Rev. J. F. Dawson on new species of Coleoptera. 215 
Beneath black: head and thorax dark metallic green, 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 antennz 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 fasciz 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 sazxatilis 
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 perhaps less depressed, and the 
punctured strize not carried to the apex, as they are in sazatilis, 
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 Clarkit. Supra nigro-picea, thorace subcordato, truncato, 
utrinque foveolato : elytris oblongo-ovatis, punctato-striatis, punctis 
sat profundis: antennarum basi, pedibusque testaceis. Long. 13

Beneath shining black, above pitchy black, head with two 
slightly flexuous striz, 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- 
tennze 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, deeply punctate- 
striate, the punctured striz 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-
