HENRY J. FRANKLIN. 369 



Pile of medium le7igth and rather coarse in texture. Face and occiput 

 with considerable yellow pile ; dorsum of thorax largely covered with 

 a mixture of yellow and dark pile ; tnesopleura yellow to the bases of the 

 legs ; dorsum of abdom.en with the two basal segments yellow, third and 

 fourth segments variable and two apical segments dark ; bases of legs 

 with considerable light pile ; wings subhy aline. Malar space long. 



Queen. Head. — Elongate trapeziform. Face with a large patch of 

 generally pure light, often whitish, yellow pile reaching some distance 

 above and below the bases of the antennae, sometimes with an admix- 

 ture of dark hairs ; occiput sometimes with a triangular patch of pure 

 light yellow pile, but usually with an admixture of dark hairs ; ventro- 

 lateral parts sometimes with a small amount of light pile, often con- 

 necting with the light patch on the occiput. Labrum with tubercle- 

 like areas moderately separated, their margins rounded and summits 

 flat or somewhat concaved; shelf-like projection not very prominent. 

 Malar space longer than its width at apex, fully one-fourth as long as 

 the eye. Clypeus rather finely and sparsely punctate over the disc. 

 Flagellum of antenna about twice as long as the scape ; third antennal 

 segment much longer than the fifth, the fifth longer than the fourth. 



Thorax. — The greater part of the dorsum covered with a mixture of 

 black and yellow (of greatly varying shade) pile and thus having a 

 distinctly clouded appearance, being darkest between the bases of the 

 wings ; the center of the disc naked ; mesopleura covered with yellow 

 pile to the bases of the legs ; metapleura sometimes largely clothed 

 with dark pile, but usually bearing light pile for the most part ; sides 

 of the median segment often entirely dark, but usually bearing a mix- 

 ture of dark and light hairs. 



Abdomen. — Dorsum : segment one with dark pile in the middle and 

 yellow on the sides, or nearly or entirely clothed with yellow pile; seg- 

 ment two entirely covered with yellow pile, or with a more or less defi- 

 nite triangular median patch of dark pile, the base of this triangle 

 being on the basal margin of the segment and its apex on or near the 

 the apical margin ; segments three and four entirely covered with fer- 

 ruginous-red pile ; segment five dark, but the apical margin often 

 fringed with light hairs; segment six dark, but sometimes with some 

 light hair on the sides. Venter with the apical margins of the seg- 

 ments fringed, for the most part, with yellow hairs. Hypopygium 

 with a median carina on its apical portion. 



Wings. — Subhyaline, only slightly stained with brown ; the fore pair 

 lightest across their middle portions. 



Legs. — Coxas sometimes entirely dark, but usually with some light 

 pile ; trochanters and femora with considerable light pile ; fore and 

 middle tibiae dark, often with a few ferruginous hairs ; corbicular 

 fringes sometimes entirely dark, but usually with more or less ferru- 

 ginous hairs.
