Similar to chamaesarachae, but the female differs in having the face marks more reduced, the facial foveae broader, the pygidal plate weakly notched at apex, and the maxillary palpi four-jointed. The male differs in having the upper margin of the white face marks more or less even and truncate at lower level of antennal sockets, with the blue of frons rarely intruding below that level. In material from Texas the marginal cell is distinctly shorter than in chamaesarachae, but this difference disappears in specimens from New Mexico and Arizona.

Female.—Head and thorax dark blue-green, the propodeum and pleura bluer. Face below antennae black, with white clypeal and lateral marks. Clypeus rarely white, except usual pair of dark dots and two submedian blackish stripes, more often dark with a small white median spot and a spot on each side of the disk, or sometimes entirely dark except the median spot. Lateral marks shaped as in chamaesarachae but smaller, or more usually concave on inner margin, sometimes reduced to a curved line or small anterior spot, and occasionally absent. Mandibles yellowish white, becoming dark rufous at apex. Labrum and antennae dark, the scape white beneath and the flagellum yellowish brown beneath. A small spot on each side of hind margin of disk of pronotum and the tubercles white. Legs black, the front and middle knees, front tibiae except beneath, and front tarsi white. Abdomen ferruginous, except the blackish lateral foveae of tergite 2. Tegulae hyaline, becoming whitish at base. Wings hyaline, the nervures pale yellowish brown, the subcosta and margins of stigma more brownish.

Head slightly broader than long. Facial foveae elongate oval, usually somewhat broader at lower end, and nearly one half as broad as the space between eye and adjacent antennal socket. Maxillary palpi with four short thin joints. Tarsal claws slender, with a minute tooth at middle of inner margin. Head and thorax mostly polished, but a delicate tessellation apparent on frons and vertex and a coarser tessellation on base of propodeum. Puncturation minute and very sparse, the punctures of frons restricted to a triangular space in front of ocelli. Pubescence white, fine and sparse. Length, 4-4.4 mm.; anterior wing, 2.8-3 mm.

Male.—Dark blue, the mesonotum more greenish. Mandibles except red tips, labrum, and face below level of antennae white; upper margin of the white sometimes almost straight, but usually more or less concave with the lateral marks extending a little higher on the orbits, and rarely with the blue of frons intruding as far as middle of outer margin of the subantennal plates. Tubercles and a small spot on each side of hind margin of pronotum white. Abdomen ferruginous with base of tergite 1 more or less dusky. Legs black, the front femora except behind, front tibiae and tarsi, basal third of middle tibiae, middle basitarsi, and middle and hind knees white or yellowish white. Antennae brown, the scape white except a small spot above at apex, the flagellum dull yellow beneath. Tegulae and wings as in female.

Head slightly wider than long, the cheeks narrow and simple. Labrum emarginate at apex. Mandibles simple and acute as in chamaesarachae. Tarsal claws more dentate than in female to become almost bifid. Sculpture and pubescence as in female, the cheeks, however, with abundant white hair. Subgenital plate triangular, bluntly rounded at apex, and less narrowed apically than in chamaesarachae. Dorsal lobes of caulis extending beyond base of the parameral lobes; the latter very broad at base, abruptly narrowed before the apex, and not at all bilobate as in chamaesarachae; sagittae subangulate at widest part, about one fhird of the length before the apex. Length, about 3.5 mm.; anterior wing, 2.8 mm.

Eight females, 8 males (holotype female, allotype, and paratypes), 15 miles southeast of Dryden, Terrell County, Texas, on Chamaesaracha coniodes, Apr. 13, 1949 (Michener and Beamer). Additional paratypes as follows.—TEXAS: 1 male, Sanderson, Terrell County, the data otherwise as in the type series; 1 female, 4 males, Davis Mountains, Jeff Davis County, on Ch. coniodes, Apr. 17, 1954 (R. H. Beamer). NEW MEXICO: 29 females, 26 males, Hot Springs, San Miguel County, July 22, 1950 (Beamer); 3 females, 7 males, 35 miles north of Hot Springs, on Baileya multiradiata, July 22, 1956 (Beamer); 6 females, 4 males, Vaughn, Guadalupe County, on Ch. coniodes, July 2, 1952 (Beamers, C. Weiner, A. Wolf, La Berge, and C. Liang). ARIZONA: 2 females, 3 males, 7 miles west of Fairbank, Cochise County, on Physalis heterophylla, Aug. 28, 1954; 4 females, 12 males, same data as last, but Aug. 15, 1955 (Timber-lake) ; and 2 males, Don Luis, Cochise County, on Ch. coniodes, Sept. 11, 1954 (Timberlake); 1 male, 4 miles northwest of Tombstone, Cochise County, on Chamaesaracha, Aug. 13, 1940 (Michener); 1 male, 7 miles east of Douglas, Cochise County, Aug. 11, 1940 (Michener) ; 8 females, 5 males, 5 miles east of Portal, Cochise County, on solanaceous flower, Sept. 14,1955, except a female on Veroesina encelioides and one of the males taken Sept. 15 (G. E. Bohart); 1 female, 1 male, 8 miles southwest of Willcox, Cochise County, July 12, 1952 (Beamers, La Berge, and C. Liang).
