somewhat narrowed in front, but behind only a very little 

 narrower than in the middle; the posterior angles are nearly 

 obtuse-angled ; the posterior margin is truncate and straight. 

 The scutellum has the same pubescence as the thorax. The 

 elytra have an ashy-grey bloom, no yellow pubescence along 

 their base, are densely punctate, nearly without traces of striae, 

 a little widened in the middle, behind obtusely acuminate. The 

 legs are ferruginous red, the thighs brown. 



The same characters which distinguish coracinus from the 

 other species in this group apply also to morio, and under that 

 species I have already given a comparison of the differences be- 

 tween them. They are however closely allied. 



This appears to be a rare species. So far as I know, it has not 

 yet been taken in Scotland. It is found in England, and is 

 widely spread over the Continent. It is included by Gebler in 

 his list of insects found in South-west Siberia. M. Kraatz says 

 it is found under leaves and in the chinks of wood.

Oblong-oval. The antenna? are as long as the 

 head and thorax, imperceptibly thickened towards 

 the point. The first six joints are reddish brown, 

 the remainder brown, the 8th joint not much 

 smaller than the rest, the last joint oval, acuminate, yellow. 

 The thorax is scarcely a half broader than long, rounded on 

 the sides, broadest in the middle; nevertheless only a little 

 narrowed in front and behind, in front rather narrower than 



* Both from his figures and descriptions it appears to me evident that 

 Sturm has transposed the names of nigrita, Erichs., and tristis, Panz. This 

 has not been noticed by Kraatz or subsequent authors, but a very short 

 perusal will I think convince them of it. For instance, of tristis, Panz., he 

 says, "the thorax broad, short," &c, and of nigrita, Erichs., "the thorax 

 narrower than the elytra, transverse," which is just reversing the characters 

 of the thorax ; and his figures speak for themselves.
