142 Colydiidee collected by Mr. A. R. Wallace. 
Penthelispa morio. 
P, fusca, nitida; prothorace subdepresso, medio longitudinaliter levigato, 
modice punctato, angulis anticis haud productis, lateribus leviter ro- 
tundatis. 
Hab. Mysol. 
Dark brown, shining (in one specimen ferruginous) ; head moderately 
punctured ; prothorax rather depressed, a smooth longitudinal space on 
the posterior two-thirds of the disk, each side of this space with a con- 
cave line with moderate-sized but very distinct punctures, the anterior 
angles not produced, the sides slightly rounded ; scutellum small, tri- 
angular ; elytra striato-punctate, the punctures oblong, the sides nearly 
parallel; body beneath dark brown, shining with coarse scattered punc- 
tures; antennee dark brown; legs dark ferruginous. Length 13 line. 
I only know of one other Asiatic Penthelispa (an undescribed spe- 
cies from Ceylon), which, inter alia, differs in having no smooth space 
on the prothorax. 
Cerylon punctipenne. 
C. oblongum, convexum, rufo-ferrugineum; prothorace antrorsum an- 
gustato, lateribus rotundatis, vage et fortiter punctato; elytris ovatis, 
fortiter seriatim punctatis. 
Hab. Morty. 
Size and form of Cerylon histeroides, but more convex, and reddish 
ferruginous, the prothorax strongly and remotely punctured, the scu- 
tellum transversely triangular ; elytra more ovate and bearing a smaller 
proportion to the rest of the body, the punctures very coarse and ar- 
ranged in rather distant lines; the tibize, especially the anterior, very 
much dilated at the distal extremity. Differs from Cerylon orientale, 
Motsch., in its greater convexity, larger prothorax more rounded at the 
sides, elytra more ovate and more coarsely punctured, &c. Length 
1} line. 
Cerylon pusillum. 
C. oblongum, subparallelum, ferrugineum, nitidum; prothorace amplo, 
modice punctato; elytris striato-punctatis, striis basin versus incurvatis. 
Hab. Mysol. 
Oblong, nearly parallel, ferruginous, shining; head rather finely punc- 
tured ; prothorax moderately punctured, as broad as the elytra at the 
base, the sides rounded ; scutellum transversely scutiform ; elytra nearly 
parallel at the sides, striate-punctate, the strize at the base curving 
inwards towards the scutellum ; body beneath ferruginous, nearly im- 
punctate ; tarsi much dilated at the distal extremity, antenne and legs 
pale ferruginous. Length % line. 
The stric of the elytra curving gradually inwards towards the 
scutellum will readily distinguish this species from any other known 
to me.
