DISTRIBUTION — In the East, Nova Scotia to Florida, April to October.

FLOWER RECORDS — Rhododendron, Rosa, Rubus, Vaccinium and Vicia. Brittain and Newton (1933) also record this species on Lonicera, Phleum, Pinus(?). Pyrus malus and Sails,.
This species can be easily confused with pennsylvanicus, but in that species the malar space is somewhat longer, the scutellum in the queen and workers is always black pubescent, and the basal abdominal tergum is yellow at least in part. In males the abdominal terga 1-5 are yellow pubescent, contrasting with the limitation of yellow to terga 2 and 3 in terricola.

COMMENTS. Little morphological variation of significance, other than size, has been noted in this subspecies. The smallest workers seen are between 8 and 9 mm long, the others ranging in size up to that given for the queen. Chromatically, however, there is considerable variability shown in all three castes. The yellow is often pale (maize yellow) and not the more typical golden yellow. The head of the queen and worker might as often be entirely black as with a suffusion of yellow on the face and vertex. The scutellum is usually black or predominantly so, but often is variously covered with yellow, and the usual black between the wings might be intermixed with yellow, sometimes almost all yellow. Thoracic pleura of the female sometimes predominantly yellow above, the usual pale lobe anterior to wing base being extended ventrad to cover nearly all the upper half of the mesopleurum; and, often in the male the thoracic pleura are almost entirely yellow. Corbicular fringes range from entirely black to predominantly burnt sienna. Rarely is the female abdominal Tl all yellow, but it is common to find specimens with varying amounts of tawny yellow intermixed, especially laterally, with the usual dominant black on this tergum. The presence of variable amounts of yellow on the male abdominal Tl is common. It is not unusual to note considerable black intermixed with the yellow (especially medially) along abdominal T2 anterior margin of otherwise typical females of this subspecies, this showing a trend toward and mergence with what was described by Franklin (1912: 271) as subspecies nigroscutatus under occidentalis Grne. (c/.). Sometimes the female abdominal terga beyond T2 are entirely black; all gradations existing from that described for T4-6 to the condition where there is a considerable intermixture of yellow on T4, and T5-6 are entirely brownish to very pallid yellow. The chromatic variability of the male abdominal terga is even more pronounced than that of the female; often T5 is almost entirely yellow, and the pile on the distal terga (especially T6-7) is pale burnt sienna, similar to that indicated for some hairs on the legs.
Compared with many other bumblebee taxa, t. terricola is among the more constant in color pattern. Yet, the quantity of material examined from all parts of the distribution clearly reveals a marked chromatic variation, particularly amongst the specimens collected in the southeastern and northwestern areas of its range. In the north central and western regions many specimens of all castes assume a color¬ation that completely merges with that of t. occidentalis (cf.) by way of what Franklin described as nigroscutatus. While typical far western t. occidentalis aver¬ages somewhat larger and would chromatically appear to be specifically distinct from terricola as described by Kirby, there are to me no evident constant or reliable morphological features by which specimens of these two overlapping (allopatric) populations can be positively differentiated in these areas of overlap. In such allo¬patric locations, obviously the two subspecies (terricola and occidentalis) interbreed and produce numerous perplexing subspecific hybrids.

Bombus terricola occidentalis
DESCRIPTION. The following descriptions are based on typical specimens representing the bulk of the far western populations of this subspecies.
Queen. Structurally not perceptibly distinguishable by any significant feature from that of /. terricola. Color: Head black except intermixture of drab brownish yellow on face, especially below antennal bases where such longer hairs tinged with burnt sienna, and on vertex. Thorax above from tegula to tegula and a little lobed ventrally anteriad of each, golden yellow; remainder of thorax black except intermixture of noticeable brownish yellow especially on posterior half of scutellum and less so on lateral portions of interalar area. Legs and wings as in t. terricola. Abdominal Tl, basal third of T4 black with few scattered hairs on T2-3 tipped with brownish yellow, remainder of T4 and 5-6 whitish except some shorter finer pile laterally on T6 with pale golden tinge evident under strong illumination.
Worker. Structurally like that of /. terricola. Chromatically like queen except inter¬mixture of yellow on face and vertex less, only very slight intermixture of yellow on thoracic dorsum posteriad of tegulae; wings somewhat paler.
Male. Structurally like that of t. terricola. Color: Head black and golden yellow, latter color predominating on face between and below antennal bases and on vertex, black pile above antennal bases with considerable intermixture of tawny yellow. Thorax above mostly ochraceous (yellow) except for poorly defined interalar black band, thoracic pleura black except for ochraceous (yellow) ventral extension anteriad of wing bases and most of remaining pleural pile tinged with burnt sienna. Legs black, most pile on coxae, trochanters, and ventrally on femora with considerable tawny yellow, that posteriorly on middle tibia and hind tibial fringes largely pale burnt sienna. Wings lightly, evenly stained with brown as in worker. Abdominal Tl-3 and narrow basally on 4 black, the remainder of 4-7 whitish. Sterna 6-7 and genitalia as in /. terricola (PI. X).
Redescribed from hypotypes. Queen, Robson, B.C., 20-IV-39, H.R. Foxlee; worker, Friday Harbor, Wash., July 2, 1939, R.W. Dawson; male, same data as worker [all HEM].
TYPE. Not examined. A $ (in fluid) which has either lost its identity or is not any longer extant. Evidently, in 1863 Cresson borrowed the Greene material from the Smithsonian Institution (Washington) and, if any of Greene's specimens still exist, my intensive search has not divulged their whereabouts.
TYPE LOCALITY. Washington (State), U.S.A., and (Vancouver Island, British Columbia, Canada). Number of specimens at hand: 1444. In flight: from late February or early March to ca. mid-November, the males first appearing in early June. Distribution: (vertical), from sea level to 12,500 ft; (horizontal), Alaska (including major Aleutian Islands), and in Canada south and southeastward to British Columbia, Alberta, and Saskatchewan, and in the United States eastward to the Dakotas and southward to Arizona and New Mexico. Floral visitations: Aster, Chamaenerion, Cleome, Epilobium, Gypsophila, Lotus, Medicago, Melilotus, Peta-sites, Potentilla, Rubus, Rudbeckia, Sonchus, Taraxacum, Trifolium and Zinnia. From Lutz and Cockerell (1920) we can add Monarda and Solidago.
COMMENTS: After having examined thousands of specimens of all castes of t. terricola and t. occidentalis I unhesitatingly agree with Handlirsch (1888a: 234), who first recognized that these forms were conspecific. Franklin (1912: 239, 272), who kept them apart was, however, aware that such a combination might be so.

As stated in the remarks appended to the description of t. terricola, I have not discovered reliable morphological characters that will justify a specific recognition of occidentalis Grne. Superficially, some far western populations appear to average slightly larger than those of t. terricola, but even this might be statistically questionable.
This subspecies shows a broad range of chromatic variability which is, in my opinion, associated with effects by a tolerance for and establishment in many dif¬ferent physical and biological habitats. The subspecies has numerous synonyms, as indicated.
Often the queen head is predominantly black, as is usual in the worker. From the typical described above, the most pronounced variation in the female is the amount of yellow on the thoracic dorsum, on abdominal Tl-3, and the complete mergence of whitish pile on T4-6 to the pale or tawny yellow that occurs on typical t. terricola; often a narrow to wide well-defined inter alar black band occurs, and sometimes the thoracic dorsum is almost if not entirely yellow; abdominal T3 fre¬quently entirely, T2 in part (especially laterally) to almost entirely covered with yellow, and on paler specimens some yellowish pile is evident on Tl, and often irregularly on T4 replacing black or whitish pile. These female color variations from the typical t. occidentalis to t. terricola range mostly through the described syno¬nyms proximus Cr. (1863a: 98), perixanthus C. & P. (1899a: 386), and nigroscu-tatus Fkln. (1912: 271). The male varies in color from that described above to specimens covered predominantly with golden yellow on head, thorax and abdominal Tl-4, with only traces of black on head, between wing bases, on metapleurum and abdominal Tl; legs of such pale specimens are also mostly yellow, the tibial fringes tinged with pale burnt sienna; and, base of abdominal T4 narrowly blackish, remainder and T5-7 pallid yellow to whitish.
By gross microscopic examination it is not always possible to positively sep¬arate many specimens of t. occidentalis (especially workers and males) with credible accuracy from those of L terricola taken in certain northwestern allopatric locations.
