Type. — Say's type oi ephippiatus is, of course, lost. Smith's 

 worker type of lateralis is in the collection of the British Mu- 

 seum and Col. C. T. Bingham v^as able to identify it for me- 

 Friese writes me that his type specimens of schneideri (the 

 queen cotypes) are in his private collection. He has sent 

 me a specimen of schneideri in good condition. The male is 

 here described for the first time, from two cotypes, one of 

 which is deposited in the collection of the United States 

 National Museum and the other in the collection of the Massa- 

 chusetts Agricultural College. 



The species is peculiar in that the workers arid males do not resemble 

 the queens in coloration. Malar space of females short. Queens, 

 workers and males with the sides of the thorax, the first abdominal seg- 

 ment and the disc of the second yellow . Queens with dorsum of thorax, 

 sides of dorsal abdominal segtnent two and segments three, four and 

 five ferruginous . In the males arid workers, this ferruginous pile of 

 the queens is replaced by black. Pile of medium lerigth, thick atid rather 

 fine. 



Queen. Head. — Mostly dark as a rule. Face and occiput often en- 

 tirely black, but usually with a more or less strong admixture of dark 

 ferruginous hairs. Clypeus sometimes with a sprinkling of ferruginous 

 hairs. Labrum with fringes rather long and ferruginous. Sides of 

 head, behind the eyes, dark. Malar space shorter than its width at the
