MALE.—Scales on head black, and white or yellow. Second antennal segment lenticular, apical margin not produced as a sharp flange.

Scales on mesonotum mixed yellowish white and black, margins with white scales, few yellow ones intermixed and some black ones on postalar callus. Scales on scutellum black, white, and yellow. Pile on mesopleuron and pteropleuron black. Scales on pleura gold and yellow. Prosternum with black pile; propleuron and anterior margin of mesonotum with mixed black and white pile, few yellow hairs on former. Postalar tuft of pile white. Scales on coxae gold and black.

Cells C and Sc of wing (Plate 2o) entirely infuscated. Cells R, 1M, and 2M entirely infuscated except for subapical and submedial hyaline spots in former, and apical stigmatic area in latter. Cell 1A with postbasal subhyaline spot, and postmedial and apical hyaline areas. Cell 2A with broad infuscated area submedially on vein 2A not reaching posterior margin, and small subapical spot on vein 2A. Cell R1 infuscated out to tip of vein Sc except for basal hyaline spot; cell 1M2 infuscated on basal third except for small hyaline spot basally on vein Cu1. Bases of cells R2+3, R5 and Cu1, infuscated. Independent spots at bases of cells R4 and M1, in cell R1 below tip of R1, on vein R4+5 between bases of cells R2+3 and R4, and medially on m crossvein.

Fore and middle femora and tibiae with black scales posteriorly and white scales anteriorly; hind femur and tibia with black scales.

Sides of first abdominal tergum with dense white pile, few yellow hairs posteriorly; hind margin with black scales medially and white scales laterally. Sides of terga two through seven with black setae and few linear black scales. Discs of terga with mostly black scales; white scales laterally and medially on posterior margin of second tergum, laterally on terga six and seven, and medially on third tergum. Venter with linear black scales, a few yellowish-white scales laterally on posterior margins of second and following sterna.

FEMALE.—Similar to male. Sternopleuron with some black scales. Cell 2M of wing with hyaline area basally. Venter of abdomen without light scales.

MALE GENITALIA (Figure 29).—Distal part of gonocoxites parallel sided in lateral view, rounded apically; apices sharply rounded in ventral view, with mesal ridges defining shallow medial sulcus. Distal segment of gonostylus inverted-trapezoidal basally, with narrow apical hook. Apex of epiphallus with sharp lateral angles, proximal process large, sharply recurved. Aedeagus narrow and sharp apically, gonopore ventral. Basal part of aedeagus enlarged, bulbous; lateral and proximal apodemes small in relation to base of aedeagus.

FEMALE GENITALIA (Figure 40).—Similar to pluto pluto. Tenth tergum with 12 spines on each side. Sclerite on each side of gonopore very narrow dorsally, with spurlike mesal extension and narrow, spatulate outer lobe.

BODY LENGTH.—6.7 to 7.4 mm.

WING LENGTH.—6.1 to 6.7 mm.

DISTRIBUTION.—Anthrax cybele probably occurs from southern California to southwestern Arizona and into northwestern Mexico (Map 10).
