are very prominent when seen from behind. Eyes moderate. 

 Thorax subquadrate, unequally impressed, a large fovea in 

 the lobe in front of the scutellumj two others placed obliquely 

 on each side of it, a transverse one in front, and a triangular 

 one on the inflexed side, which is sinuate ; posterior angles 

 obtuse, and posterior margin of median lobe truncate, straight. 

 Scutellum triangular. Elytra with the shoulders not very 

 prominent, and the apex fimbriated with fine denticulations. 

 Underside shining aeneous, fulvo-pubescent, acicularly rugose. 

 One specimen. 



(Subgen. Polyonychis^ Chev.) 



This subgenus is not accepted by Lacordaire nor by Kiesen- 

 wetter, although the former so far inclines to adopt it as to 

 point out the characters which distinguish it from CoroebuSj 

 and the latter divides Coroebus into two sections, of which the 

 one has the characters of Goroehus as restricted by Chevrolat, 

 and the other those of this genus [Polyonychus). Although 

 the seizable generic characters are trifling, the difference in 

 facies is tolerably marked ; and I therefore think it a useful 

 section, worthy of being preserved, particularly in a family 

 which is so numerous, and of which the species are so much 

 alike as the Agrilidce. The true Coroehi are the broader flat 

 species with irregular patches or bands of different coloured 

 pubescence, of which C. rubi may be taken as the type, while 

 the more uniformly metallic and less banded species, such as 

 C. elatuSj compose the genus Polyonychus. It is to be ob- 

 served, however, that the name is not happy ; for both Coroebus 

 and Polyonychus have equally the claws of the tarsi split in 

 two.

This species differs in the following respects from Castelnau 

 and Gory's description and figure of Agrilus Sophorce^ to 

 which it was referred by some continental entomologists to 

 whom I sent it. In the first place the tarsi are short, more 

 especially the first article, which is inconsistent with the genus 

 AyrtluSj in which Castelnau and Gory place Sophorce. Pass- 

 ing that, it is, like it, a small bright-green insect like an Agri-
