ocelli of the male are removed from the margins of the 

 eyes by distinctly less than their own diameter. Is it the 

 same as Friese's B. weisi albocaudata male ? Tucuman is in 

 Argentina.

Types. — Col. C. T. Bingham succeeded in identifying 

 Smith's type queen, for me, in the collection of the British 

 Museum. It was collected in Colombia. The types of 

 Friese's varieties are in his private collection. The worker 

 type (Handlirsch description), also from Colombia, is in the 

 collection of the k. k. Hofmuseum at Vienna. The typical 

 male is here described for the first time — from three speci- 

 mens, of which one is deposited in the collection of the 

 Massachusetts Agricultural College and the other two in the 

 collection of the United States National Museum. These 

 males all came from Colombia. 



Pife rather long and rather fine. Malar space short in the male and 

 rather short in the females. Ocelli of females distinctly below the supra- 

 orbital line and very slightly above the narroivest part of the vertex ; 

 those of the male considerably below the supra orbital line and in the nar- 

 rowest part of the vertex, the lateral ones being separated by about half 

 their own diameter frotn the eye margins. Eyes of male considerably
