162 AMERICAN HYMENOPTERA. 



Three of the workers before me are from Callanga and one 

 is from Ecuador. 



The veination of the fore wings and the formation of the 

 apex of the hind metatarsi of the workers lead me to place 

 this species in the subgenus Bombias and Friese's descrip- 

 tion of the male—" as worker, but with larger eyes " — makes 

 me confident that I am right in doing this. The ocelli of 

 the worker are, however, placed as in the subgenus Bomhis. 



Its closest ally is evidently rubicundus, from which it can 

 be readily separated by marked differences in the coloration 

 of its pile. 



The species was named for Herr Anton Handlirsch, a bee 

 student of Vienna. 



Friese has sent me a worker of this species, from Ecuador, 

 in good condition and determined by him.

Type.— Col. C. T. Bingham found Smith's type specimen 

 in the collection of the British Museum for me. It came 

 from Colombia. Friese's workers came from Ecuador 

 (Cuenca, 2200 meters altitude) and Mexico (Colon). The 

 male is here described from two specimens (from Colombia), 

 the cotypes of that sex, deposited in the collection of the 

 United States National Museum and the collection of the 

 Massachusetts Agricultural College.

 ferruginous. Head of queen with rufo ferruginous pile ; of worker and 

 male mostly dark. Dorsum of abdomen of queen either entirely rufo-

 worker and male partly rufo ferruginous and partly dark fuliginous ; of 

 worker sometitnes mostly black. Corbicular fringes black. 



Queen. Head. — Broad and rounded in form. Face, occiput and 

 sides usually bearing little but rufo-ferruginous pile ; sometimes with
