Ohs ,—My notes made upon the Fabrician collection at Kiel, in 'wbicb the typical specimen 
is preserved, state that this insect is a Myrmecodes. Its colours seem to indicate it as a female 
of this group.

This species is very nearly allied to T. variabilis, but it is at once 
distinguished from that species by its uniform smaller size, the 
almost uniform colour of the thorax, and the nearly hyaline wings 
of the male. The head in this sex is aeneous black, closely and 
finely punctured, and clothed with short close fulvous pubescence; 
the clypeus is yellow, which colour is extended along the anterior 
and posterior margin of the eyes, higher than the insertion of the 
antennae; it forms also a slendei* branch behind the eyes. The 
mandibles are fulvous with black tips, the antennae black and 
slender. The thorax is slightly aeneous black, finely punctured, 
and tomentose like the head, with a slender transverse yellow line 
behind the scutellum and the metathorax, with a large patch above
