. Closely resembles T. ivalshi, darker, but identical in sculp- 

 ture and pilosity. The head is shorter, nearly square, the scape 

 and legs are proportionately much shorter, the metanotal spines 

 shorter and more stoutly built. The pedicel has the nodes trans- 

 verse, broader than long, but proportionately longer than in 

 T. walshi, while the petiole of the 1st node is very distinctly 

 shorter than in that species. 



Length, 2 mm.
