The heaa (Fig. 124; is as broad as pronotum, oblong, scarcely 

 broadened posteriorly, at middle smooth, the sides with fine and rath- 

 er scattered punctation, the surface very finely transversally aci- 

 culate; antennae robust, after the lonj first joint distinctly genic- 

 ulated, their second and third Joints of equal length; pronotum anteri- 

 orly as broad as elytra, narrowing posteriorly, oblong, the surface 

 very finely, yet distinctly transversally aciculate and with 12-16 

 punctures in dorsal rows, the sides with rather fine, ana somewhat un- 

 evenly scattered punctation; elytra as long as, or sometimes a little

Distributed everywhere in Europe and North Asia, and common in this 

 country, as well on dry as damp ground, not infrequently in company 

 with ants, especially Formica rufa and lasius fuliginosus . 



X. longiventris Heer (Kraatz Ins. Z. II, 641; Thorns. Skand. ':;ol. 



II, 191; Muls. et F.ey Bre'vip. 1877, €7] is seemingly only a somewhat 



deviating form of linearis . It has longer elytra and fewer (lC-12), 



— -( Pa-^e 438 ) 



larger punctures in pronotal rows; head and pronotum with smooth surface 



or indistinctly transversally aciculate. - None of these characters are 



however settled or unchangeable and therefore not sufficiently strong 



to separate the species.
