MELIPONID/E. 



TRIGONA Jurine. 



Trigona cassise Cockerell. 



Workers from Brisbane, 8-2-16 {Hacker), and Caloundra, 20-1-16. (Hacker). 



One of the Brisbane specimens has a dark red abdomen, but it is certainly conspecific, 



and possibly not fully matured. 



Trigona Iceviceps Smith. 

 Many years ago I recorded Trigona canifrons Smith from Adelaide R., 

 Australia, basing my identification on comparison with specimens from Ceylon, 

 received from Mr. E. E. Green as canifrons. Unfortunately the Ceylon specimens 

 were really T. loiviceps Sm., and not canifrons at all. A specimen now before me, 

 from Gordonvale, N.Q., June, 1918, collected in the scrub by Edmund Jarvis, is 

 identical with the so-called canifrons of Austraha. I am quite unable to clearly 

 separate it from loeviceps, though it is rather slender, with the abdomen dark 

 sepia-brown, becoming black apically. Possibly a larger series would indicate a 

 distinct form, but I am inchned to think that we have the Indian lavicep^ probably 

 accidentally introduced into Austraha. Bingham states that it builds in crevices in 

 the walls of houses, so it seems quite possible that a nest might be carried with some 

 kind of merchandise. The red antennse distinguish if from the alhed and certainly 

 native T. carbonaria Smith.
