The female, except for shape of head, seems to be indistinguishable 
from the female of cephalosus. The species is represented by four 
males and four females, the type series of three pairs from one bird, 
the other pair from another, taken at Carraipia, La Guajira, Colombia. 
Note.—The drawing of D. cephalosus published in 1936 (pl. 24, fig. 
1) shows the front of the head too convex. There is actually a slight 
depression in the middle of the frons, but much less than in D. 
microgenttalis.

I have a large series of this handsome species taken on several in- 
dividuals of Mothoprocta o. ornata, collected at Callipampa, Inca- 
chaca, Choros, and Potosi, Bolivia. There seems to be no valid 
grounds for separating these insects from hzrsutus, they being ex- 
tremely similar in all respects, except the single character of more, 
and more prominent, internal projections on the frons. However, 
since this character, I find, is subject to individual variation, it does 
not seem sufficient for their separation.

This species was described from two males and one female, all in 
rather poor condition. I have recently secured fresh material from 
the type host, taken in northern Colombia. The published figure of 
the male genitalia is somewhat misleading, and a corrected one is 
herewith presented. 
The chaetotaxy, as shown in the published figure of the male, is 
very deficient, and we have the following additions: Four short, 
dorsal hairs on the frons, two marginal and two submarginal; two 
ventral hairs on each side of head just forward of antennal bands; a 
dorsal hair on each side of base of mandibles; two submarginal hairs 
on middle of temples instead of one; a long hair on posterior margins 
of abdominal segments IT to V near the small hair shown in the figure; 
an additional hair on segments IV and V on the posterior margin, in- 
side the lateral angle; two median ventral hairs also on segments III 
and IV; four dorsal hairs on median portion of posterior margin of
