found in Southern India,

were busy tending her, and removing some eggs or larvae. It is the 

 only female I have seen of this genus, and is well characterized 

 by its large eyes, and ocelli. 



13. OCODOMA QUADRISPINOSA, N. S. 



Worker nearly l-8th of an inch long, head smooth ; eyes small ; 

 thorax with two small spines anteriorly, and two large carved 

 spines posteriorly ; first abdominal pedicle long, raised, rounded 

 behind ; second also rounded, blunter, of equal height ; head, legs, 

 and thorax dark rufous ; abdomen blackish brown. I have not 

 seen the Warrior (if any) of this race, which I found during the 

 monsoon forming a small temporary mud abode round the head of 

 flowers of a species of Leucas, abundant in Malabar. It appeared 

 to be feeding on the vegetable secretions surrounding the seeds. 



Of these seven species of Ocodoma the first and last are very 

 distinct from all the others, the first by having only rudimentary 

 spines, and the last by having four spines instead of two. Ocodoma 

 Minor is readily distinguished by its smaller size ; and the other 

 four are most readily distinguished inter se, by the jaws of the 

 Warriors, which in No. 10 is entire, in 11 with two teeth at each 

 angle ; in 9 with moderately strong teeth throughout its extent ; 

 and in 8 with the jaw very finely toothed. 



Gen. Eciton. 



The characters of this genus are thus given by St. Fargeau. 

 " Antennae entirely free, head .elongated, and the thorax without 

 " spines ; maxillary palpi long, of 6 joints ; jaws linear ; wings 

 44 unknown." I have got four species of Ant which perhaps may be 

 ranged under this genus, of which only one species is described, 

 and that from South America, but it is more than probable that 

 they will form a new genus to which however I will not attempt 

 to impose a name. My species have a long slender body, oblong 

 head, large eyes, short antennae, inserted very near the mouth, 

 linear or oblong jaws, and sting very severely. 



14. ECITON ? RUFONIGRUM, N, S. 



Worker, length about ll-24th of an inch ; head square ; antenna- 

 short, first joint thickened ; very long palpi, eyes large, lateral,
