derus), the true Anchomeni, e. g., A. albipes and oblongus ; but the ex- 
treme forms of EHya and Selina remind one rather of Anthici or ants. 
They inhabit moist situations, running nimbly over muddy edges of 
pools or about the roots of herbage. 
Genus Evpatta. 
Castelnau, Trans. Roy. Soc. Victoria, pt. ii, vol. viii, p. 102. 
The author of the genus gives scarcely any characters, and places 
it in the sub-family Ctenodactyline, from which the distinctly truncated 
elytra distinguish it. On dissection, I find the ligula rather short, tri- 
angular, with two long sete on its straight upper edge, besides a short 
one at the angles, which are rectangular; the paraglosse are quite free 
from the upper part of the sides, narrow, and incurved. The mentum 
is broad, with a very broad simple tooth in the middle, much shorter 
than the wings, which are externally rounded. The palpi have the ter- 
minal joints very nearly cylindrical, in the labial less so than in the 
maxillary, in which latter they equal in length the preceding. The 
maxille are strongly hooked and densely spinose within. The surface 
of the body is punctulated, and, with the legs, clothed with short pale 
pubescence, as in Lachnophorus ; the slightly dilated male tarsi are also 
precisely of the same form as in that genus. The truncature of the 
elytra is, however, more decided, and is slightly incurved, and the head 
forms a very distinct neck at its junction with the thorax. The margi- 
nal stria of the elytra is not continuous along the apical margin.
