NO. 2264. BEES IN THE NATIONAL MUSEUM. 3—COCKERELL. 211 



TRIGONA CLYPEATA Friese. 



8^. Abdomen at least partly red or light; mesothorax not polished. 

 11a. Face black, with pruinose pubescence; abdomen varying from 

 red at base only, to reddish with hind margins of segments black. 



TRIGONA TOGOENSIS Stadelraann. 



lib. Lower margin of clypeus with a dull white band; abdomen 

 lively orange fulvous, with hind margins of segments black. 



TRIGONA ZEBRA Friese. 



This has been considered a variety of T. dypeata, but it seems to 

 be distinct. Another related form is T. quagga Strand. 



lie. Clypeus, supraclypeal mark and broad lateral face-marks 

 cream-color or yellow; clypeus with two faint brownish clouds, not 

 alwaj'S evident. 



TRIGONA NEBULATA Smith. 



There are specimens of this from Mount Coffee, Liberia, May, 1897 

 (E. P. Currie). 



The United States National Museum contains 10 species of Asiatic 

 THgona^ of which only the following calls for remark : 



TRIGONA BIROI Friese. 



The type of this species must be considered to be one of those col- 

 lected in New Guinea by Biro. Friese records it at the same time 

 from the Philippine Islands, where it seems to be common. Speci- 

 mens come from Los Banos (Baker), and others were collected by 

 C. K. Jones in a locality not specified. Three are from flowers of 

 Niya fruticans, "Lamao, Batan," February 26, 1916 (P. J. Weeter). 

 For the present it is assumed that all these insects are the same, but 

 it may be that the Philippine form is distinct from that of New 

 Guinea, and possibly there is more than one sort in the Philippines. 

 The specimens are mostly in poor condition, so that it is impossible 

 to be sure of all their characters. The Philippine T. Mroi has a red 

 scape, and although very close to the Australian T. carbonaria, I am 

 sure it is a distinct species.
