Pile short and coarse. Fe)na/es entirely, and males tnostly, black, ex- 

 cept third dorsal abdominal ses^mettt, this being covered ivith yellow pile. 

 Malar space of females somezvhat shorter than its width at apex, nearly 

 one-fourth as long as eye. Squamcs of genitalia with outer lobe very 

 short almost wanting. 



Queen. Head. — Entirely dark. Malar space somewhat shorter than 

 its width at apex, nearly one-fourth as long as eye. Clypeus moder- 

 ately punctate, with rather coarse and very fine punctures mixed, 

 rather sparsely so on front part of disc. Third antennal segment 

 longer than fifth and fifth longer than fourth. 



Thorax. — Entirely black. Center of dorsal disc with a considerable 

 area naked. 



Abdomen. — Entirely dark, except third dorsal segment ; this segment 

 clothed, for most part, with yellow pile, except on very basal portion, 

 this portion being thinly clothed with very much shorter black hairs. 

 Hypopygium without a median carina. Surface of epipygium elevated 

 somewhat in middle of very apical portion. 



JVings. — Very dark and with strong violaceous reflections. 



Legs. — Entirely dark. 



Worker. — Like queen, but with slightly lighter wings. Malar space 

 apparently somewhat shorter, in proportion to length of eye, than that 

 of queen.. 



Male. Head. — Mostly dark ; face with mostly cinereous pile (this 

 pile being darkest above the bases of the antennae, there being a much 

 more sparse admixture of the long dark hairs on the clypeus); occiput 

 .sometimes with a faint admixture of yellow pile. Malar space nearly 

 as long as its width at apex, nearly one-fourth as long as eye. Clypeus 

 mostly covered up with usually light cinereous pile. Third antennal 

 segment slightly shorter than fourth, the fifth much longer than the 

 fourth. 



77/ora,r.— Entirely dark. Center of dorsal disc with a noticeable 

 naked area. 



Abdomen. — Dorsum : segments one and two entirely dark ; segment 

 three mostly yellow, sometimes with the yellow pile replaced, on the 

 very basal portion, with very short black hairs ; segment four either 

 entirely covered with yellow pile or with yellow pile on the basal por- 

 tion and the very apex bearing black pile ; segments five, six and seven 

 entirely dark. Venter mostly dark, but with apical fringe of last seg- 

 ment ferruginous and the fringes of some other segments tinged with 

 the same color. 



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

 like that oi peimsylvanicus (fig. 132). Ends of branches (figs. 160 and 

 164) rounded, not angled, on their inner sides. Volsellae with nar- 

 row apices, their apical projections triangular and blunt pointed ; with 

 a very prominent rounded projection on their inner sides, a little be-
