Rev. J. F. Dawson on new species of Coleoptera. 215 



Beneath black : head and thorax dark metallic gveen^ shining, 

 the former with a broad frontal impression on each side behind 

 the eyes, back of the head smooth and glabrous : mandibles 

 pitchy : palpi testaceous with the apex pitchy : first, second, third 

 and basal half of the fourth joints of the antennae red, the rest 

 fuscous black, all the joints (except the second) rather long : 

 thorax convex, heart-shaped, narrow, not much more than half 

 the width of the elytra at the base, which has a deep fovea on 

 each side, hinder angles acute : elytra oblong, rather wide and 

 depressed, the sides somewhat parallel, with the tip gently 

 rounded, coarsely punctate-striate, with two deeper impressions 

 on the third stria ; the apex smooth, pitchy red, with two reddish 

 testaceous fasciae more or less obscure and obsolete, sometimes 

 wholly wanting : legs testaceous red. 



Not unfrequent in the north of England on the banks of the 

 Tyne and Derwent, and mentioned in the ' Catalogue of the In- 

 sects of Northumberland and Durham^ as a variety of saxatilis 

 by Mr. T. J. Bold, to whom I am indebted for my series. It is 

 however sufficiently distinct from that species ; for independently 

 of the colouring the structure is different, and while the elytra 

 are considerably broader and pei'haps less depressed, and the 

 punctured striae not carried to the apex, as they are in saxatilis, 

 at the same time the thorax is smaller, narrower in front and more 

 convex. Dr. Schaum, whose attention I called to the species, after 

 a careful examination and comparison of the specimens which I 

 had given him with their continental allies, both at Paris and 

 Brussels, informed me that it is unknown. 



Genus Lopha, Megerle. 



5. Lopha Clarkii. Supra nigro-picea, thorace subcordato, truncate, 

 utrinque foveolato : elytris oblongo-ovatis, punctato-striatis.punctis 

 sat profundis : antemiarum basi, pedibusque testaceis. Long. 1| 

 lin. 



Beneath shining black, above pitchy black, head with two 

 slightly fiexuous striae, between which is an elevated ridge, on 

 each side behind the eyes somewhat approximating in front • 

 mandibles pitchy red, palpi pitchy black, basal joint of the an- 

 tennae wholly and base of some of the following ones pale red : 

 thorax oblong heart-shaped, truncate before and behind, disc 

 convex, transversely wrinkled, with the sides dilated and rounded 

 before the middle, then narrowed, but leaving the base suffi- 

 ciently broad, which has a large rugged fovea on each side, hinder 

 angles acute : elytra oblong-ovate, wide, convex, deejjly punctate- 

 striate, the punctured striae abbreviated before the apex, which 

 with the sides is smooth, and has an obsolete blood-red spot 

 near the outer margins : legs entirely red. In its general struc-
