., Worker, length not y^^th of an inch; eyes anterior; thorax 



wide; abdomen long, elliptical; head and thorax brown; an-^a 



tennse, legs and abdomen pale whity brown. ^ 



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



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



difficulty. It feeds on flowers and vegetable secretion^^jjel 0^1 ao

cj— 45. Formica nidificans, Jerdon (p. 125). I 



Worker, /^ths of an inch long ; head triangularly ovate, ele-' 

 vated; eyes moderate; jaws strongly three- toothed ; thorax 

 wide anteriorly, narrowed behind, with two small spines ante- 

 riorly pointing forwards, and two large ones behind pointing 

 upwards and backwards, and two rudimentary spines or points 

 behind and beneath these latter; abdominal pedicle square, 

 raised, with two large upright spines, and a smaller one on eachfg 

 side ; abdomen short ; head and abdomen rufous ; thorax darbs 

 glossy brown. j 



Female, ^rd of an inch long, similar to the worker; three ? 

 ocelli on top of the head : wingless. 



This ant makes a small nest about half an inch, or rather..', 

 more, in diameter, of some papyraceous material, which it fixes j 

 on a leaf. I have opened two, each of which contained one 

 female and eight or ten workers. It is very rare, and I have 

 only seen it in Malabar. 



o'^^^:>^ 46. Formica sylvicola, Jerdon (p. 126). -y% 



Worker, y^ths of an inch long; head narrowed in front and' 

 rounded behind; eyes posterior, salient; antennae inserted in; 

 front of the eyes, with a strong crest bordering their insertion ' 

 internally ; jaws short, with five teeth, the upper one much the 

 longest and bent ; thorax wide, with two spines on its anteriorta 

 angles, and two stronger ones posteriorly pointing backwards 

 and upwards; abdominal pedicle large, square, ending behind • 

 in two large curved spines, pointing backwards and outwards^ r, 

 and two points or tubercles behind and between them; abdomen b 

 short, oval, colour dull black; abdomen shining glaucous green. I 



Female, 2^*^^ ^^ ^^ i^^^ loiig^ differs in the anterior thoracic 

 spines being apparently shorter, and in having three ocelli: ^ 

 wingless. ^ 



This ant has the same habits as the last, but is not found^^ 

 except in the jungles. It appears very closely allied to F. hastata 

 of Latreille, from India, and to several other species said to be 

 from Southern Asia; and as many of these may be found in
