 slightly narrowing, slightly convex, dorsum with two, more or less dis- 

 tinct longitudinal impressions, separated by a slightly elevated inter- 

 val, and back of this most often confluent, at the side-margins further 

 more with a small fovea at middle; elytra considerably broader than, 

 and fully twice as long as pronotum, posteriorly feebly broadened, with 

 dense and robust punctation; abdomen especially finely and rather dense- 

 ly punctated. L. 3 mm. 



In the o the first four joints of fore-tarsi are feebly dilated; the 

 sutural angle of elytra is more acute, and abdomen more tapering post- 

 eriorly than in the Q . 



It is found under bark of deciduous and pinacious trees, which are 

 infested with bark-beetles, also under moss on or around old stubs, or 

 under rotting plants, is distributed in forth and Middle Europe, but in 

 most places, also in this country very rare, and most often found singly 

 (Ry, Silkeborg; Sora, Kefge, Donse; Almindingen in Bornholm). In Skaane 

 the larva found in a hollow oak and reared by Mag. A. Kemner, Lund (19/4 

 1914). 



The larva is illustrated and described by Perris (Ann. Soc. Ent. Fr. 

 1853, 573, T. 17, Fig. 44-48). It lives in the burrows of the bark-beet- 

 les, and is apparently feeding on their youn* and offal. 



Closely related to Coryphlum angusticolle is Boreaphilus Hennlnglanus 

 Sahib. (Kraatz Berl. Ent. Zeitschr. 1857, 41, T. I, 4 b). It resembles 

 Coryphium in size and color etc. and is like this distinguished in, that 

 the next-last joint of maxillary palpi is pyriform thickened, and the last
