HENRY J. FRANKLIN. 153 



Clypeus, for most part, densely covered with nearly pure pale yellow 

 pile. Occiput mostly dark, but bearing a mixture of dark and yellow 

 hairs in the middle. Behind the eyes dark. Ventro-lateral portions 

 of head almost entirely dark, but with a slight admixture of yellow 

 hairs almost opposite the lower ends of the eyes. Malar space but little 

 more than half as long as its width at apex. Ocelli large and placed 

 somewhat less than one-third of the distance toward the bases of the 

 antennas from the supra-orbital line, exactly in the narrowest part of 

 the vertex, the lateral ones being separated from the margins of the 

 eyes bj' about half their own diameter. Eyes swollen so as to cause 

 the vertex to appear distinctly depressed between them, about as in 

 the male of separatus. (The antennae of all the males before me are 

 lost.) 



Thorax. — Coloration of pile about like that of the queen and worker, 

 but the black interalar band fully half as long, from front to rear, as 

 wide, from wing base to wing base. 



Abdomen. — Dorsum : segments one, two and three entirely covered 

 with yellow pile ; segment four dark, but with some of the hair on its 

 hind margin tipped with white ; segments five, six and seven clothed 

 with long, fine white pile (most of the hairs of this pile are dark brown 

 or black at the base and shade out to white, so as to appear entirely 

 white unless examined with a lens). Venter mostly dark. Apical 

 margin of both epipygium and hypopygium entire. 



Genitalia. — Outer spatha in general form much like that of rtifo- 

 cinctus (fig. 122), but much longer {i. e., with a much greater dis- 

 tance between the front and hind margins); the hair on the ventral 

 surface of the apical portion sparse and short, being thickest and most 

 conspicuous on the hind corners. Inner spatha appearing much like 

 that of rufocinctus (fig. 55), but with a conspicuous rounded-triangu- 

 lar fenestra on each side of the middle of the front part of the apical 

 portion. Claspers (figs. 181 and 197) long, but apparently powerful ; 

 branches broadly rounded at apex as seen from dorsal side ; squamae 

 strongly bilobed, the outer lobe being much the larger, triangular in 

 shape and with evenly curved inner and outer margins and pointed 

 apex, and the inner lobe being rounded at the apex and extending 

 mesad but slightly beyond the inner margin of the volsella. Volsella; 

 only very moderately hairy ; considerably widened in the middle by a 

 broadly rounded protuberance on the inner side of each ; their apical 

 projections not very large, but conspicuous and with serrate inner 

 margins. Sagittae with long and nearly straight shafts and recurved 

 heads ; the heads considerably foliaceous and projecting mesad in a 

 somewhat sickle-shaped foliaceous extension ; considerably outreached 

 by the apices of the volsellae. Uncus quite broad at base, but taper- 

 ing gradually to the moderately wide, rounded and recurved tip. 



^?«^.J.— Somewhat darker than those of the queen, but somewhat 

 lighter than those of the worker.
