Colour generally fuscous, either unicolorous, or with a pale dorsal streak. Head 

 with the vertex prominent, meeting the frons at an acute angle ; eyes prominent, 

 lateral ocelli above the insertion of the antennae, central ocellus at the lower end of 

 the frontal sulcus ; frons looking forwards and downwards, sulcate above, with a 

 raised ridge on either side, replaced in the middle by a single median ridge, which, 

 towards the clypeus, diverges on either side. Pronotum narrow anteriorly, dilated 

 above the insertion of the wings, produced posteriorly into a long pointed process, 

 not reaching beyond the posterior knees, with the median ridge considerably elevated, 

 making the pronotum tectiform, generally with a black spot on either side behind 

 the broadest part. Lateral flaps of the pronotum bilobed at the posterior mar- 

 gin (one-lobed in the immature insect). Elytra lateral, short, lobiform, coriaceous. 

 Wings as long as the process of the pronotum in $ , much shorter in ? . Posterior 

 femora robust, with sharp, straight ridges. Prosternum produced anteriorly, sur- 

 rounding the mouth parts. Abdomen, above compressed, below flat, with two 

 longitudinal ridges. Valves of the ovipositor rugose, denticulate. 



Length, 7'5 — 11 mm. 



Brunner says this species is found over nearly the whole of 

 Europe, chiefly in the north and middle. I have it from several British 

 localities. It should be looked for in dry places in woods, fields, and 

 under dead leaves, and probably will be found plentiful and widely 

 distributed. 



Fieber figured and described the larva of bipunctatus as a new 

 species {Schrankii), depending chiefly on the one-lobed posterior mar- 

 gin of the side flaps of the pronotum ; but, as Brunner {op. cit., p. 

 237) points out, this is a character of all the species in their immature 

 stage. Dr. Buchanan White recorded Schrankii, Fieb., from Scotland 

 in 1870 {vide Ent. Mo. Mag., viii, p. 25).
