no. 3603 HERMETIA JAMES AND WIRTH 15 



niinal abdominal terga is dense and golden. The abdomen usually is 

 wholly black; sometimes, in the males, the terminal segment may be- 

 come reddish brown, and occasionally a pair of pale, but not translu- 

 cent, spots may appear on the second tergum. The male genitalia 

 are reddish yellow to reddish brown; the basistyle is robust; the disti- 

 style, from ventral view, oval, its apex, when viewed laterally being 

 rounded and projecting only very inconspicuously (fig. 3). 



Geographic distribution (fig. 12): Southern Sinaloa (Elota, Maz- 

 atlan) to Durango and San Luis Potosi (Ciudad del Maiz) south to 

 Oaxaca (Oaxaca, Camaron) and Guerrero (Amula, Venta de Zapilote, 

 recorded by Williston, 1900). We have records from the following 

 Mexican states within the above distributional area: Zacatecas, 

 Aguascalientes, Nayarit, Guanajuato, Jalisco, Michoacan, Morelos, 

 Veracruz, and Puebla. Seasonal records run from March to late 

 October; however, this may merely reflect lack of collecting during 

 the winter months.

The supra-antennal callus is distinct and the area above the frontal 

 callus rugulose, with two rather low carinulae; the mesonotum is 

 wholly whitish to yellowish pilose, the pile thin except on the pre- 

 scutellar band; a narrow presutural vitta is present in the male but 

 absent in the female. The wing is brown with a yellow area extending 

 the length of the second basal cell across the discal cell to the anterior 

 margin and apex of vein R, so that both the posterior half of the wing 

 and the anterior margin to the stigma remain brown; the differentia- 

 tion in color is more marked in the female than in the male. The hind 

 tibia is blackish to black on its apical third to half, the others reddish 

 brown in the same area. The abdomen, at least when viewed from 

 behind, is reddish brown in both sexes, the color more reddish in the 

 male; however, the yellow pile of the abdomen is not as prominent as in 

 H. chrysopila, more nearly comparable to H. ryckmani, and each 

 tergum bears a broad transverse band of black pile, the yellow pile 

 usually being limited to the extreme base and the apical half of the 

 tergum. The male genitalia are similar to those of H. ryckmani. 



So far as we know, this species is restricted to the southern part of 

 Baja California (fig. 11), and other records in the literature pertain 

 to other species. Townsend's types came from San Jose del Cabo and
