on the center of the disc (in middle of black band) naked, this area 

 being smooth in the middle, but strongly punctate around its margins. 

 Mesopleura covered with yellow pile to bases of legs. Metapleura and 

 sides of median segment with mostly yellow pile. 



Abdomen. — Dorsum : segment one yellow; segment two yellow on 

 its basal middle and also more or less so on its hind margin, especially 

 on its hind corners, the remaining portion being black ; segment three 

 yellow; segments four, five and six black. Venter dark. Epipygium 

 with a distinct longitudinal median apical carina. Hypopygium not 

 carinate. 



Whigs. — Very dark and with distinct violaceous reflections. 



Legs. — Coxae mostly dark, but usually with some yellow hairs on 

 outer sides ; trochanters usually entirely black, but sometimes with 

 some yellow pile on lower sides ; femora and tibiae entirely dark. 



Worker. — Like queen, but wings distinctly lighter, though still dark; 

 epipygium without a distinct median carina ; second dorsal abdominal 

 segment sometimes with no yellow pile on its basal middle and some- 

 times with no yellow on its hind corners or hind margin. 



Male. Head. — Rather elongate. Face, occiput, and ventro-lateral 

 portions bearing a mixture of black and shorter and finer whitish pile. 

 Malar space as long as its width at apex, nearly one-fourth as long as 

 eye. Clypeus mostly naked over a large portion of disc ; sides and 

 basal portion clothed with a mixture of black hairs and short, fine, 

 whitish pile ; middle of anterior portion with an elongate smooth area; 

 otherwise densely and coarsely punctate. Third and fourth antennal 

 segments subequal in length, the fifth much longer than either. 



Thorax. — Coloration of pile about like that of worker, but with black 

 interalar band distinctly narrower. 



Abdonieji. — Dorsum : coloration of pile like that of queen, but with 

 considerable yellow on extreme sides of fourth segment ; hind margin 

 of second segment bearing yellow pile throughout its length ; apical 

 segment dark. Venter mostly dark, but with the lateral portions of 

 the apical margins of most of the segments fringed more or less with 

 pale hairs. 



Genitalia. — Outer spatha much like that oi pemisylvaniais (fig. 126). 

 Inner spatha much like that of pennsylvanictis (fig. 132). Claspers 

 (fig. 182) of medium length and apparently powerful ; in general, 

 much like those of peiuisylvatiicus (fig. 70). Sagittae much like those 

 of fervidus (fig. 102), but with no serration of the outer margins of the 

 heads. Uncus moderately broad at the base, but gradually tapering 

 to the rather narrow recurved tip. 



Wings. — Strongly infuscate ; somewhat lighter than those of worker. 



Legs. — Coxae with more or less yellow hair; hind trochanters dark, 

 but the fore and middle pair with much yellow pile on their lower 

 sides ; fore and middle femora with much pale yellow pile on their lower
