HENRY J. FRANKLIN. 171 



Legs. — Coxae, trochanters, femora and tibiae clothed with dark brown 

 or black pile. 



Male. Head. — With black pile only. Malar space very nearly as 

 long as its width at apex, about one-fifth as long as eye (longer than 

 that of any other Bonibias male known to me) . Clypeus largely naked, 

 or sparsely pilose, and moderately coarsely punctate. Ocelli placed 

 distinctl}^ below supra-orbital line and very slightly above narrowest 

 part of vertex ; lateral ones distinctly nearer to margins of eyes than 

 to each other, but separated from eyes by distinctly more than their 

 own diameters. Eyes only very slightly swollen (less so than the eyes 

 of any other Bombias male known to me) . Third antennal segment 

 longer than fifth ; the fifth longer than the fourth. 



Thorax — Pile all black. An area on front part of middle of scutel- 

 lum naked and another area on center of dorsal disc naked and mostly 

 smooth. 



Abdomen. — Dorsum : segment one black, but with a slight admix- 

 ture of coccineo-ferruginous pile on extreme sides. Segment two 

 mostly coccineo-ferruginous, but with black pile in middle ; segments 

 three and four covered with entirely coccineo-ferruginous pile ; seg- 

 ment five mostly coccineo-ferruginous, but with a mixture of white 

 and black hair on apical middle ; segment six with some short black 

 hairs in middle, but clothed for most part with white pile ; segment 

 seven with mostly white pile. Venter mostly black, but with apical 

 margin of apical segment bearing a heavy fringe of short ferruginous 

 pile. 



Genitalia. — Outer spatha (fig. 155) very short and broad, with a 

 large reticulated area on each side of the posterior portion of the ven- 

 tral surface, these areas being united by reticulations running along 

 the hind border ; the front margin deeply incurved ; the side margins 

 curved inward in front and outward behind ; the hind margin deeply 

 incurved in the middle. Inner spatha much like that of fervidus (fig. 

 101), but with anterior median projection much more prominent than 

 in that species and with hind margin of apical portion somewhat out- 

 curved. Claspers (figs. 185 and 191) long and apparently thick and 

 powerful ; the branches, as seen from dorsal side, with moderately 

 wide and broadly rounded apices, the ventral side of each branch hav- 

 ing a single very noticeable branched hair rising from the bottom of 

 a rather deep pit, this pit being located opposite the base of the vol- 

 sella and well away from the margin ; the volsellse rather short in com- 

 parison with the other parts of the genitalia and unusually densely 

 and evenly hairy over their entire surface as seen from the ventral 

 side and without noticeable projections of any sort, except the small, 

 elongate and rather slender apical projections ; the squamae strongly 

 bilobed, the two lobes being about equal in size, the outer lobe being 

 slightly the longer and the inner one somewhat the broader, the outer
