green, the head and thorax rather thickly covered with soft grej-ish 

 vello^v hairs ; elytra mth three longitudinal, considerably raised keels, 

 between each of which is a slighter keel ; in the male these lat er are 

 abbre^-iated, between the keels the elytra are closely punctured; the 

 elytra in the male are of a brownish yellow, the punctured parts, ex- 

 cept at the base, being darker in colour ; m the female the elytra are 

 of a clear ochre yellow ; in the male the antennse are of a dull ferru- 

 ginous, the base of the joints paler ; the legs are lerrugmous m the 

 male, while in the female they are of the same dark coppery green as 



the head and thorax. , , v i.i,„ 



In a female specimen the elytra are of a very dark olive-green ; the 



specimen is rather larger than the other.

BiMiA, n. 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 

 antenna;, the hinder margin widely smuated. - , . . , ,.^ 



Antenna 11-jomted, shorter than the body ; first joint clavate, 

 cylindrical, slightly longer than the third; second jomt small moni- 

 hform ; third, fourth and fifth joints straight, compressed, and nearly 

 of the same length ; the sixth shghtly bent and compressed ; the five 

 last joints compressed and gradually smaller, the last blunt a the tip. 

 Thorax wider than long, with a strong spme 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 stouldeis 

 prominent, the sides nearly parallel, the ends slightly pomted ; the 

 ^ngs large, and extending beyond the elytra and abdomen. Legs 

 strong, slightly compressed; femora somewhat thickened ; hmd legs, 

 if extended, would reach a little beyond the abdomen. Tarsi scarce y 

 wider than the tibiae ; penultimate joint deeply cut ; soles densely 



covered with short hairs. nr / j, „,,^ 



This genus would seem to be placed not far from Molorchus, and 

 may be allied to Jffapete, 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.
