head (lcn:«oly and distinctly punctate; tlie parts of the mouth 

 red. The tlmrax is rather depressed and is thickly and finely 

 punctured, witii a tine ycllowish-srrey dense pubescence ; it is 

 half as broad again as long, lightly rounded on the sides, 

 somewhat narrowed in front, but l)eliind only a very little 

 narrower than in the middle; the posterior angles are nearly 

 obtuse-angled ; the posterior margin i.s 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 stri«;, 

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

 legs are ferruginous red, the thighs brown. 



The same characters which distinguish corachms from the 

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

 species I have already given a comj)arison 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 antennse 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 



* Both from his figures and descrijjtions it appears to mc evident that 

 Sturm ha.s transposed the names of niyrita, Eriehs., and tristis, Panz. Tliis 

 has not been noticed by Kraatz or subsequent autliors, l)iit a very short 

 pem-sal will I think convhice them of it. F'or instance, of tristis, I'anz., he 

 savs, "the thorax broad, short," &c., and of niyrita, Eriehs., "the thorax 

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

 of the thorax ; and his figures speak for themselves.
