of a clear ochre yellow; in the male the antennz are of a dull ferru- 
ginous, the base of the joints paler ; the legs are ferruginous in the 
male, while in the female they are of the same dark coppery green as 
the head and thorax. 
In a female specimen the elytra are of a very dark olive-green ; the 
specimen is rather larger than the other.

BiMIA, 0. g. 
Head as wide as the thorax in front, somewhat narrowed behind, 
in front square and nearly perpendicular, grooved down the middle ; 
jaws short and strong ; eyes deeply notched for the insertion of the 
antennz, the hinder margin widely sinuated. 
Antennz 11-jointed, shorter than the body; first jomt clavate, 
cylindrical, slightly longer than the third; second joint small, moni- 
liform ; third, fourth and fifth joints straight, compressed, and nearly 
of the same length; the sixth slightly bent and compressed ; the five 
last joints compressed and gradually smaller, the last blunt at the tip. 
Thorax wider than long, with a strong spine on each side about the 
middle, its disc depressed and slightly unequal. Scutellum largeish, 
hollowed slightly in the middle. Elytra rather narrow, not so long as 
the abdomen, soft, not meeting except at the base; the shoulders 
prominent, the sides nearly parallel, the ends slightly pointed; the 
wings large, and extending beyond the elytra and abdomen. Legs 
strong, slightly compressed ; femora somewhat thickened ; hind legs, 
if extended, would reach a little beyond the abdomen. Tarsi scarcely 
wider than the tibie; penultimate joint deeply cut; soles densely 
covered with short hairs. 
This genus would seem to be placed not far from Molorchus, and 
may be allied to Agapete, Newman, Zoologist, iii. p. 1017: it is not 
unlikely that the other sex is very different in form and colour; there 
is only one specimen in the Museum.
