anterior angle, one lateral one just behind the middle and four 
forming a dorsal line behind the middle with its lateral bristle 
quite close to the one in front of it: in addition there are two 
shorter bristles near the median line close to the posterior margin 
which are undoubtedly homologous to the scutellar bristles al- 
though there is no trace of a scutellum. Wing narrow, strap- 
shaped, strongly bent near the middle, its outer edge clothed with 
fine bristly hairs at the base and small bristles apically, and in 
addition with a series of five longer bristles each about half as 
long as the wing. Abdomen with the second tergite chitinized, 
one-third longer than wide, the base four-fifths as broad as the 
apex; anterior angles rounded, posterior ones sharply angulate; 
with the usual hairs and row of minute apical bristles. Third 
tergite absent; fourth very small, crescentic, with four marginal 
bristles; fifth a minute band with a circular ring behind enclosing 
the gland opening, with two minute bristles at tip. Posterior 
margin of second to fifth segments with a row of minute bristles; 
sixth segment bristly medially and at tip. Legs rather stout, 
the hind metatarsi unusually stout. 
Type from Hamburg, Farm, Sen Jose, Costa Rica (F. Never- 
mann) taken with Eciton sp. 
This species agrees closely with the previously described 
species. From E. yarva Schm. it may be distinguished by the 
complete absence of the third tergite and longer wing bristles;, 
from E. bruchi Schm. by the presence of 14 frontal bristles; from 
E. comes Schm. by the presence of eight dorsal thoracic bristles 
and a greater number of wing bristles; and from E. collegiana 
Borgm. and E. cequalis Borgm. also by the eight thoracic bristles. 
Heretofore no species of this genus have been reported outside of 
the South American continent.

A species probably referable to this genus was taken by Dr. 
Mann in the nest of Pheidole in Mexico. It differs greaty 
from the type and only described species of Ecituncula in having
