HENRY J. FRANKLIN. 427 



Male. Head. — Rounded in outline as viewed from in front. Face 

 argely clothed with yellow pile from near the lower margin of the 

 clypeus to some distance above the bases of the antennae, but usually 

 with a more or less strong admixture of black hairs with the yellow ; 

 occiput largely covered with yellow pile ; cheeks often entirely dark, 

 but usually with more or less yellow pile connecting with the yellow 

 on the occiput. Malar space about one-third as long as its width at 

 the apex. Ocelli placed in the narrowest part of the vertex ; the lateral 

 ones separated from the margins of the eyes by about one-half their 

 own diameters. Flagellum of antenna about three times as long as 

 the scape ; the third and fifth antennal segments about equal in length, 

 the fourth much shorter than either. 



Thorax. — The dorsum covered with yellow pile, but the disc often 

 bearing more or less black hair ; mesopleura covered with yellow pile 

 to the bases of the legs ; metapleura and sides of the median segment 

 clothed with yellow pile. 



Abdomen. — Coloration of pile of dorsum much like that of the worker, 

 but the extreme side margins of the third segment often with touches 

 of yellow. Venter mostly dark, but usually with more or less yellow 

 pile, especially in the middle. 



Genitalia. — Outer spatha (fig. 129) with anterior margin deeply in- 

 curved ; the side margins strongly incurved in front, but broadly 

 outcurved behind ; the hind margin straight or somewhat incurved ; the 

 posterior portion of the ventral surface rather thickly set with moder- 

 ately long, branching hairs. Inner spatha (fig. 127) with the sides of 

 the anterior margin nearly straight and nearly in the same straight 

 line ; the side margins incurved slightly ; the apical margin somewhat 

 variable, but usually nearly straight ; the apical portion of the ventral 

 surface thickly covered with long, branched hairs ; a large, elongate 

 fenestra often present somewhat in front of the center. Claspers (figs. 

 85 and 90) with volsellae tapering gradually toward their tips, their 

 apical projections long, prominent, somewhat recurved and with more 

 or less serrate margins ; squamae with lobes separated by an unusually 

 shallow indentation of the inner margin ; ends of branches rather 

 strongly quadrate in appearance as seen from dorsal side. Sagittae with 

 rather wide shafts and very broad, rounded, foliaceous heads, the 

 outer margins of the latter being more of less strongly serrate, espe- 

 cially at the base. 



Wings. — Usually somewhat lighter than those of the worker, only 

 moderately stained with brown. 



Legs. — Coxae mostly dark, but the hind pair usually with some yel- 

 low hair on their outer sides ; trochanters mostly dark, but often with 

 a little light pile ; femora all with a large amount of yellow hair ; fore 

 and middle tibiae dark, but often with some slightly ferruginous hair 

 on their hind sides ; hind tibiae with outer faces mostly or entirely
