other times without wings. It feeds both on vegetable and animal 

 substances preferring the former like all the true Formica. 



42. Formica Assimilis, N. S. 

 Worker, exceedingly similar to the last. 



Length, 3-24th of an inch, differs in its colour chiefly being of a 

 shining reddish black, in its eyes being apparently large, the thorax 

 narrower, and in being covered all over with scattered white hairs. 



I have found it frequenting flowers in Malabar, but not abundant. 



43. Formica Phyllophila, N. S. 



Worker, length 7-48th of an inch, eyes small, anterior, jaws trian- 

 gular ; thorax slightly furrowed posteriorly; abdominal pedicle 

 thin, low, linear ; abdomen large triangular ; legs antennae rather 

 short : colour shining brown black. 



This little species forms a temporary nest between two leaves 

 usually, or sometimes in a head of flowers ; it lives in small socie- 

 ties, and feeds entirely on vegetable secretions. 



44. Formica Nana, N. S. 



Worker, length not 1-1 2th inch; eyes anterior, thorax wide ; 

 abdomen long, elliptical ; head and thorax brown ; antennae, legs, 

 and abdomen pale whity brown. 



This very minute species is found in all parts of India and is 

 very abundant in Mysore ; from its very small size is noticed with 

 difficulty. It feeds on flowers and vegetable secretion. 



2ndly. With spines on the thorax. 



45. Formica Indificans, N. S. 



Worker, 5-24th of an inch long ; head triangularly ovate, elevat- 

 ed ; eyes moderate ; jaws strongly 3 toothed ; thorax wide ante- 

 riorly, narrowed behind, with two small spines anteriorly pointing 

 forwards, and two large ones behind, pointing upwards and back- 

 wards, and two rudimentary spines or points behind and beneath 

 these latter ; abdominal pedicle square, raised with two large up- 

 right spines, and a smaller one on each side ; abdomen short ; head 

 and abdomen rufous, thorax dark glossy brown. 



Female l-3d inch long, similar to the worker; 3 ocelli on top of 

 head; wingless.
