CARABID^E. DYSCHIRIUS. 31 



8. D. jejunus : capita thoraceque nigro-cmeis, capite rugoso, 



thorace ovato, elytris amis, elongatis, erebre punctato- 

 striatis, tibiis anticis extus fortiter bidentatis. (PI. I. f. B.) 



This insect has the head and thorax brassy black, the former 

 rather obscure ; elytra brassy or brownish brass. Head rugose, 

 transversely strigose in front, with some traces of a longitudinal 

 elevation, which is lost in the rugosity which entirely covers the 

 head ; mouth, mandibles, base of the palpi and three joints at 

 the base of the antennae red. Thorax ovate, very slightly 

 narrowest in front, rather widest about the region of the posterior 

 angles, convex, having a distinct dorsal furrow deepest at the 

 base and towards the apex and the usual transverse impression 

 in front, which is strongly striated longitudinally both above 

 and below, the disk of the thorax being otherwise wrinkled. 

 Elytra elongate, shoulders slightly elevated, sides appearing at 

 first sight parallel, but in reality widest in front and a little 

 narrowed behind, apex rounded, very finely punctate-striated, 

 more faintly so before the apex, interstices flat ; legs red, anterior 

 tibiae furnished with two long spines at their extremity of equal 

 length, but the outer one much stouter, slightly curved and obtuse 

 at the tip ; armed likewise externally with two distinct strong 

 obtuse teeth, the lower one largest. Length If line. 



We are indebted to the exertions of Mr. Bold of Newcastle 

 for the discovery of this unique species. Two examples were 

 captured by him on a damp sandy bank by the river Irthing 

 a little above Lanercost Abbey, Cumberland, in June. They 

 were returned to him from Paris as entirely unknown. Mr. Bold 

 having kindly placed them at my disposal for the purpose, I have 

 for the first time introduced them as a new species. 



9. D. seneus : emeus, nitidus ; thorace breviter ovato, elytris ob- 



longo-ovatis, punctato-striatis, stria marginali ad humerum 

 abbreviatd, tibiis anticis extus acute bidenticulatis.
