Name, Location and Description

W.T. Davis’ description1 from 1917:

Type male from west of Vega, Oldham County, Texas, July 15, 1917 (Miss McGill). Davis collection.

A black and light orange or straw-colored species, with rather prominent eyes, and a conspicuous pruinose spot on each side of the abdomen. Head above black with the following marks light orange-colored : a spot on the rather prominent front, a triangular one just behind this, two small ones (one larger than the other) above each antenna, and an irregular one each side of the ocelli at the back of the head. Pronotum black with the anterior margin faintly touched with light orange; the posterior margin more broadly so, the light band being about one half a millimeter in width. The anterior angles are light orange, and the tops of the raised portions, occupying the central part of the pronotum, are orange-colored and darker than the margins. Mesonotum black with a well defined pruinose stripe on each side near the base of the wings. The hind margin is light orange including the ridges of the elevated X. The central portion is occupied by two light spots at the extremities of the X, and anterior to the depressions there are four others, the two central spots being curved and the outer ones more rounded. Tergum black with two pruinose spots at the base, one large one each side below the tympanum, and the eighth segment also conspicuously pruinose. The posterior edge of each segment is narrowly edged with light orange. Fore wings with the costal margins straw-colored to the end of the radial cells, beyond darkened; subcostal veins black; first and second cross veins infuscated. The basal cell of each fore wing contains a conspicuous black, longitudinal mark, with the posterior portion of the cell nearly clear. The flaps of both fore and hind wings are grayish in color. Beneath light straw-colored, with what dark margins there are about the head, nearly concealed by pruinose. The transverse rugae are orange with the sides black and the hollows well filled with white silken hairs. There are also many hairs in the rather shallow median sulcus, and longer ones under the eyes. The legs are straw-colored, inconspicuously touched and lined with black. The opercula, straw-colored with the extremities rounded and the inner margins
