HENRY J. FRANKLIN. 119 



covered up with pile. Third antennal segment about three-fourths as 

 long as fourth, the fifth considerably longer than the fourth. 



77/ora.*-.— Entirely black ; a noticeable naked area present on the 

 center of the disk. 



Abdomen. — Entirely dark. 



Genitalia. — Outer spatha much like that of sonorus (fig. 32). Inner 

 spatha much like that of f>enHsylvatiicus (fig. 132). Branches (figs. 

 161 and 167) rather sharply rounded on inner sides of distal ends as 

 seen from dorsal side. Volsellae with distal ends very broad and not 

 extending far beyond tips of squamae ; apical projections triangular, 

 the free angles of these projections being acute angles. Squamae 

 shaped somewhat like those of pennsylvaniciis (fig. 66), but with outer 

 lobe narrower and rather pointed at apex and with indentation between 

 this lobe and the inner one deeper. Sagittae with shafts slightly bent 

 outward in the middle and with heads shaped much like those of pul- 

 latus and medius, their outer margins being distinctly, though not very 

 deeply, serrate ; much longer and larger, in comparison with the 

 claspers, than those of pullatus or vieditis, extending somewhat beyond 

 the tips of the squamae and almost as far back as the tips of the vol- 

 sellae. Claspers appearing much thicker, in proportion to their length, 

 than m pullatus or niedius. 



Wings. — Dark and with violaceous reflections. 



Legs. — Some or all of the coxte and trochanters with a scattering of 

 dirty whitish hairs, though mostly dark ; femora and tibiae black ; 

 hind tibiae with outer faces convex and hairy throughout, with no long 

 fringes and without a trace of corbiculte ; hind metatarsi with outer 

 faces distinctly concaved and with no long fringes. 



Dimensio?is. — Length, 12| mm. to 15 mm. ; spread of wings, 33 mm. 

 to 39 mm. 



This species is apparently most closely related to medius 

 and pullatus, but it may be readily separated from those spe- 

 cies by means of the differences in the genitalia already 

 noted. 



This may be the true male of kohli. 



Bombus (BombiLs) brevivillus new species. 



This species has the same doubtful bibliography as that 

 given to iiiger. 



Type. — Described from a single queen from Pernambuco, 

 Brazil, deposited in the collection of the United States Na- 

 tional Museum. 



Pile short and coarse. Entirely black. Malar space of a little more 

 than average length.
