Types. — Not improbably in the collection of the British 

 Museum, but their identity apparently lost as Col. C. T. 

 Bingham wrote me that he was unable to find them. The 

 beautiful colored figures given with the original description 

 are sufficient to identify the species with certainty. 



Pile very long and fine. Head of females black. Thorax entirely 

 covered with light pile, except for broad black interalar band; dorsum 

 of abdomen yellow at base, black in the m-iddle and zvhitish or ferrugin- 

 ous at apex. Wings light. Malar space very long. 



Queen. Head. — Elongate in form. Face entirely black, except for 

 occasionally a slight tuft of light pile between the bases of the an- 

 tennae ; occiput usually entirely black, but sometimes with a very slight 

 sprinkling of light hairs ; sides of head behind eyes entirely dark. 

 Tubercle-like areas of labrum with summits not very deeply con- 

 caved and only very sparsely punctate and upper (posterior) margins 

 rounded, the space between them, above the shelf-like projection, rather 

 small ; translucent areas small and dim, almost absent. Malar space 

 between one-third and one-half as long as the eye ; clypeus sparsely 

 punctate over disc, rather smooth and shining ; fiagellum of antennae 

 about twice as long as scape ; third antennal segment distinctly longer 

 than the fifth, the fifth longer than the fourth. 



Thorax. — Dorsum entirely covered with very light yellow, in some 

 specimens whitish, pile, except for broad black interalar band ; the 

 yellow on the anterior part not quite reaching back to the tegulas in 

 some specimens; anterior border of black band bending forward, and 

 posterior backward in the middle, its length along the middle line, 

 from front to hind margin, distinctly more than half its width from 

 wing base to wing base ; scutellum bearing only light pile. Meso- 

 puelra entirely covered with light (whitish in most specimens) pile,
