Type locality . — Barro Colorado, Canal Zone, Panama. 
August 1, 1925, W. M. Wheeler. 
Host. — Eciton hamatum (Fab.) 
Described from a single specimen. 
In habitus, in the structure of the trophi, antennae, and in 
the tarsal formula this species belongs in the genus Zyras, but 
cannot be assigned to any of the indefinite subgenera. It is 
related to mimulus Sharp, but is much longer and differently 
colored and the thorax is relatively longer. 
In form and sculpture Z. ecitonis somewhat resembles 
species of Tetradonia, but the latter has the outer lobe of the 
maxillae short (in Z. ecitonis they are longer than the inner lobe) 
and very much longer antennae.

lines; clypeus transverse, truncate, and with a thin fringe of 
very fine hairs at anterior border. Mandibles with moderately 
abundant, short, erect, stiff hairs. Pronotum transverse, sides 
nearly straight, anterior corners very broadly angulate, trun- 
cated margin short, feebly arcuate, anterior border concave, 
posterior border rather strongly arcuate at middle; sides and 
anterior border with a rounded margin which is thickened at 
posterior third of sides, and on the sides bears a feebly impressed 
line; surface evenly convex, with abundant coarse shallow 
setigerous punctures (some of them “tear shaped”). Disc of 
elytra with seven striae (not counting the marginal and sub-
