had a box of pigeons containing some squabs placed in a room on 

 the floor. I next morning found several of the squabs dead cover- 

 ed with these Ants chiefly however the warriors. 



37. Formica Stricta, N. S. 



Worker, length 7-20th of an inch ; head nearly square, slightly 

 narrowed anteriorly ; jaws rough, triangular, strongly toothed ; eyes 

 large, posterior ; prothorax wide, metathorax narrowed ; post 

 thorax in the form of a rounded raised narrow platform, ending 

 in two points, and truncated ; abdominal pedicle blunt, rounded, 

 raised ; abdomen short, oval ; antennae rufous, head and thorax 

 dull greenish black, shagreened; abdomen shining glaucous green- 

 legs shining black. 



I have found this Ant on flowers in Malabar, but have not seen 

 its nest ; it is not a very common species. 



38. Formica Cinerascens, Fabr. ? 



Worker, length 3-8th of an inch ; head large, eyes rather small 

 posterior ; jaws strongly toothed ; thorax wide in front, narrowed 

 behind with 2 glands on each side above ; abdominal pedicle elevat- 

 ed, conic ; abdomen oval ; colour dull black, except the abdomen, 

 which is glaucous green, and somewhat pubescent. 



Female \ inch long nearly ; head smaller, thorax not so wide ; 

 abdomen long, oval ; wings not reaching to the end of abdomen. 



Male 3-12th inch long ; similar in form to the female, but with 

 much narrower abdomen, and head still smaller proportionally. 

 Warrior, 5-1 2th of an inch long ; head large ; antennae short ; «yes 

 minute. 



This species lives in the ground in small societies. I have only 

 seen it in the Carnatic. It is described as having the head fulvous, 

 and a triangular spot on the abdomen, but as it is said by Fabricius 

 to have been sent from Tranquebar, in the vicinity of which I have 

 seen our present species, I think they are probably identical, and 

 that the difference of colour is accidental, especially as there are 

 only two species common in the Carnatic with glaucous abdomen, 

 this and our F. rufoglauca.
