collected by the late M. Mouhot, Sc. 303 
the vertex a somewhat polished elevation, Thorax once and a- 
half as broad as long, anterior margin straight; sides rather 
sinuous, gradually diverging posteriorly, base straight; disk re- 
_ motely punctured, with a faint coppery dorsal line, met at the base 
by a deep puncture; sides very deeply and rugosely punctured, 
with a rugose fovea almost touching the lateral margin about one- 
third of the entire length of the thorax from the base (this cha- 
racter appears to be very variable, as in some specimens it hardly 
exists at all). Scutellum small and brilliant. Elytra a little 
broader than the thorax, irregularly impressed at the base; sides 
rather sinuate as far as the centre, then converging to the 
apex, which is obtuse; posterior margin denticulated; disk 
punctured, the punctures becoming larger and closer together 
as they approach the sides; just above the margin is a well- 
marked carina, which extends from the shoulder to the apex. 
Beneath punctured, covered with remote hairs, Legs punctured, 
hairy. 
Length 17—14 lines; breadth 54—43.

Allied to I. aurolimbata, H. Deyr., but differs by its deeply 
punctured elytra, its much longer thorax, and its coppery head.

Lampetis puncticollis, n. sp. 
L. zxreo-viridis; capite rugoso; thorace rugose punctato, 
linea dorsali levi, basi duabus impressionibus notata ; elytris 
punctato-striatis, interstitiis foveis aureis numerosis minutis 
interruptis : Subtus punctata. 
Dark bronzy-green, with coppery reflexions. Head rugose 
and flat in front; margins of the eyes: ciliated. Thorax twice as 
broad as long; anterior margin nearly straight and somewhat 
elevated, especially at the sides ; sides gradually rounded and di- 
verging posteriorly ; base almost straight, posterior angles slightly 
enclosing the base of the elytra; disk remotely punctured, with a 
broad smooth dorsal line, met at the base by two deep punctures ; 
sides deeply and largely punctured. Scutellum smooth and small. 
Elytra scarcely broader than the thorax, gradually converging to 
the apex, which is faintly ciliated ; each is armed at the apex 
with two spines, the sutural ones obtuse; disk punctate-striate,
