There are only two bristles in the supra-alar region, one each side of 
the sutural depression; two or three on the post-alar callus; one, strong, 
on post margin of mesopleura. Hypopygium complicated; claspers with 
numerous long bristles along the sublateral margin; between the bases of 
claspers is a broad appendage with a rounded, laterally directed, tooth- 
like projection. = 
Q. Similar. Wings generally darker, more blackish. Pile mostly 
black; that on cheeks, base of proboscis, and on scutellum generally, re- 
maining pale; it is also less abundant especially on the legs. Length— 
18 mm.

Pogonosoma ridingsi new species. 
o. Similar to dorsata but more robust. Mesonotum and scutellum 
not shining but subopaque. Color of bristles and pile similar except on 
the face where they are pale (yellowish not white) with several long black 
bristles on the prominence medianly; of the scutellum and postcoxae, 
black. The facial pile is more abundant than in dorsata, and along the 
alar margin of the mesonotum and on the postalar calli there are numer- 
ous black bristles, while the scutellum has some erect bristle-like hairs of 
the disc. The vestiture of the pleurae is more abundant than in dorsata 
and the pile on the fore legs is very dense, noticeably more so than on 
the middle and hind legs. The wings, although probably they will show 
much variation, seem to be fairly constant in having the fuscous clouding 
confined to the veins, even those near the costal margin (none of the speci- 
mens showing the density of dorsata). The hypopygium more robust, 
similar in general form; but the appendage between the bases of the 
claspers is tooth-like, not developed laterally into tooth-like lobes. The 
bristles of the claspers are stronger and fewer in number. 
9. Similar, but as in dorsata the pile is mostly black, being pale 
(brownish) on the cheeks only. The wings as in the male. Length 20 
mm.
