COLOBOPSI&. 



343 



Xode of the pedicel thick, oval, sometimes trausverse ; abdomen 

 short, broad, oval. 



5 min. Similar to the ^ maj. in the shape of the thorax and 

 abdomen, but the anterior portion of the head is only bent down 

 at an obtuse angle, scarcely truncate. 



2 ■ Similar to the g maj. in the shape of the head, but the- 

 thorax and abdomen are, as usual in all ants, more massive. 



The species of Colohopsis, though widely diffused in ludia, 

 Burma, and Ceylon, are nowhere very plentiful. One species, 

 C. puhescens, lives in hollows of trees, and the ^ min. on being 

 touched emits an acrid milky juice.

g maj. Black with a few scattered 

 erect brown hairs, and a soft thin 

 greyish pile chiefly visible on the 

 abdomen ; antennae, thorax and legs 

 very dark castaneous brown, almost, 

 but not quite, black. Head very

 in front than across the vertex, 

 the anterior truncated portion 

 of the head depressed, the basal 

 portion of the clypeus being thus 

 bent downwards and inwards ; the 

 cbeeks on either side of the depressed 

 portion acutely ridged and coarsely 

 obliquely striate ; the lower portion 

 of the head above truncation lon- 

 gitudinally striate. Thorax narrow,
