4 Mr. T. V. Wollaston 07i a neiv genus of Colydiidce. 
Pseudotarphius Lewisii, n. sp. 
P. sat ovalis, niger, opacus, rugose sciilpturatus, sqiiamis 
cinereis pins minus dense variegatus, sctisque suberectis 
parce obsitus ; prothorace gibboso, in disco obsolete bi- 
fasciciilato, ad latera (anguste marginata) valde et rcquali- 
ter rotundato ; elytris (subter squamis transversim rugosis 
ac grosse seriatim punctatis) convexis et ad latera rotun- 
datis, plus minus obscure cinereo-squamoso-maculatis (sc. 
macula majore longitudinali juxta scutellum, et circa 4 
rainoribus, plus minus confusis aut etiam evauescentibus) ; 
antennis tarsisqvie obscure rufo-ferrugineis.

The general outline of this Tarphius-, or Coxelus-, 
like little insect is very peculiar, — its prothorax and 
elyti-a being both of them exceedingly convex, and sepa- 
rately rounded, which causes it to seem much divided in 
the middle (or rather at the junction of the two); whilst 
its roughened and setose surface is more or less obscurely 
clouded, or even (in unrubbed specimens) maculated, with 
dirty-white scales. The blotches, or spots, into which 
these paler scales tend (on the elytra) to condense them- 
selves are in much the same positions as the nodules and 
patches are (when developed) on the Tarphii, — a rather 
large and longitudinal one being on either side of the 
scutellum, and about four smaller ones on each elytron, 
the one behind the middle disk having a tendency to form 
with the corresponding one on the opposite elytron a kind 
of extremely ill-defined postmedial fascia, wliich however 
is manifestly only traceable when the specimens are liighly- 
coloured and fresh. 
It gives me great pleasure to name the species after its 
discoverer, — whose entomological researches in Japan have 
brought to light so many novel, and geographically in- 
teresting, forms.
