2 cTJssororo, N.W.D., Dec. 1918 {Bodkin). 



In Friese's table it runs to C. moesta (Cress.), but it is 

 quite distinct. It appears to be closely allied to Tetrapedia 

 melanopus^ Sclirottky, from Paraguay, but it is doubtless 

 distinct. Schrottky's description is short, and he does not 

 mention the hind spur. He describes the face-markings as 

 yellow. 



Trigona capitata. Smith. 



Three workers ; Berbice River, 1,2. vi. 1913 {Edgar 

 Beckett). 



In these specimens the axillse and lateral margins of 

 mesothorax are yellow (reddened by cyanide). The same 

 is true of specimens from Para, received by the U.S. 

 National jNIuseum from Dr. Friese. In specimens from 

 S. Paulo, Brazil [Schrottkij) , the axillae are pale or black, 

 and the lateral stripes of mesothorax are very short and 

 weak, extending forward only as far as the tegnlas. Smith, 

 in his original description, refers to the lateral stripes, but 

 leaves us to infer that the axillre were black. The dark 

 variety of T. capitata has been named virgili^ Friese. 



The U.S. National Museum has T. capitata from Alhajuelo, 

 Panama, 28 May {Busk), and Esparta, Costa Bica, 18 Sept. 

 {F.Kriab). 



Trigona Jafy, Smith. 



Three workers ; Canister Falls, Nov. 1919 {A. A. 

 Ab7'ahani). 



These specimens have the abdomen darker than usual, and 

 possibly constitute a separable race.
