Male.--(See figure 1 for genitalia.) Length 17 mm. Head: clypeus broadly truncate, with no central emargination; frontal suture distinct to anterior ocellus; a broad and quite shallow frontal depression; surface of frontal depression finely reticulate and with very many small punctures, rest of frons with only a few small punctures but with numerous large punctures; pilosity of head black. Thorax: collar narrowly rounded; rectangle with rather shallow, moderate-sized punctures, mesopleuron with these punctures elongated; metapleuron with the moderate-sized punctures elongated and with fine ridges between them; propodeal side with many moderate-sized to small punctures, fine ridges as on metapleuron; tiny punctures scarcely evident anywhere on thorax, but the surface is roughened or reticulate; no metanotal flange; pilosity of thorax entirely white except on anterior part of prothorax, where it is black. Wings: vein R5 (2nd transverse cubital) nearly perpendicular to vein Rs (radial). Abdomen: first two, and anterior half of third, segments red, rest of abdomen black.
Female.--Length 16 mm. At first glance appearing quite different from male; structurally, however, practically identical except for usual sexual differences. Head: clypeus slightly to very moderately bulging in middle, sloping gradually to upper edge, which is curved and not very distinctly marked; surface of clypeus with many large punctures, very few small punctures, distinctly reticulate on upper half but rather glossy on lower part; frontal depression distinctly reticulate. Thorax: pilosity black. Legs: arolium very small, barely projecting beyond base of claws. Abdomen: entirely black.
Redescribed from a male and a female located in the collection of the University of Minnesota at St. Paul, Minn. Male, Parkdale, Colorado, June 15, 1926 (E. G. Anderson) ; female, Westcliff, Colorado, June 19, 1926 (E. G. Anderson).
Holotype.--Female, Rocky Mountains. It is located in the British Museum (Natural History) in London.
Allotype.--Male; the holotype of pacifica becomes the allotype of luctuosa. It was collected at Pacific Grove, California, July 9, 1897, by Miss Rose Patterson, and is now located in the Museum of Comparative Zoology at Cambridge, Mass.
Specimens examined: 722 male, 747 female; total specimens 1469.
Luctuosa has been collected in the following states and provinces:
MAINE, NEW HAMPSHIRE, VERMONT, MASSACHUSETTS, CONNECTICUT,
NEW YORK, MICIIIGAN (May 21-Oct. 12), WISCONSIN, MINNESOTA
(May 16-Sept. 15), NORTH DAKOTA, SOUTH DAKOTA, NEBRASKA,
KANSAS, MONTANA (Apr. 26-Aug. 16), WYOMING, COLORADO (Mar.
20-Nov. 1), NEW MEXICO, UTAH (Mar. 11-Oct. 4), ARIZONA, IDAHO,
NEVADA, WASHINGTON (Mar. 21-Sept. 9), OREGON, CALIFORNIA (Jan.- Dec.), NOVA SCOTIA, NEW BRUNSWICK, QUEBEC, ONTARIO, MANITOBA,
SASKATCHEWAN, ALBERTA, BRITISH COLUMBIA, YUKON TERRITORY.
Variations.--Rarely with a very slight metanotal flange; rarely with frontal suture obsolescent or entirely obsolete; in eastern specimens rectangle usually with fine ridges running forwards and downwards, these not usually present in western specimens; in some western specimens punctures of rectangle may be rather large, deep and round, almost as in communis. Male : length 12-20 mm.; in eastern United States and Canada pilosity usually entirely black, in western United States and Canada pilosity usually white on most of thorax; all gradations between the two conditions found in Minnesota; clypeal margin occasionally not broadly truncate but more rounded, sometimes making an extra bend before extending transversely to center; frontal depression sometimes with only a few punctures; rarely pilosity of cheeks white, though with a few hairs black basally, and tips of a few hairs on frons white, otherwise head black pilose. Female: length 12-20 mm.; clypeus rarely almost flat, with no bulge whatever; upper edge of clypeus occasionally not defined at all; arolium sometimes large enough to be confusing with communis; one female with dull red spots on dorsum of first, second, and third abdominal segments.
Luctuosa is extremely closely related to communis. The most reliable characters to use in separating these two species are given following the description of communis.
