The structural characters seem to be altogether those of the 
European species of the genus unless the shortness of the antennce 
be considered aberrant; many species with short antenne from 
Java, &c., have, however, been attributed to Sphwroderma.

P. lubricata, sp. nov. Elongato-ovata; pernitida ; supra eeneo- 
viridis, prothorace aurato, antennis piceis basin versus 
testaceis ; subtus piceo-nigra, pedibus rufis (femoribus plus 
minusve seneo-tinctis ; capite sublevi; prothorace fortiter 
transverso, lateribus pone apicem fortiter dentatis, disco 
sparsius minus fortiter (lateribus sat crebre sat grosse) 
punctulato ; elytris leviter striatis, striis crebre sat fortiter 
punctulatis, interstitiis planis (apicem versus leviter con- 
vexis) subtilissime punctulatis ; tibiarum posticarum pro- 
cessu apicali quam tibia tota plus quam triplo breviori, ad 
latera pectinato, ad apicem fortiter bidentato. Long., 13 1.; 
lat., 4:1. 
The reddish-testaceous color of the legs (including the femora), 
—only in places with a brassy metallic tone overlying the red 
color,—distinguishes this species from its allies ; it is also notable 
for the flat interstices (only feebly convex near the apex) of its 
elytral striz.

(Sub-tribe) GALERUCIDES. 
The Australian Polynesian and Papuan Phytophaga of the sub- 
tribe Galerucides present considerable dithiculties to thier student 
owing to the great uncertainty that exists in respect of some of 
the genera—an uncertainty notably illustrated by the frequency 
of the mark ‘“?” after the generic designations of species 
described by even well known specialists. In a recent investiga- 
tion of the Galerucides of my collection I have found among those 
insects many species previously undescribed, but in several 
instances have been unable to reach any confident conclusion as 
to what is their right generic position. As this difficulty arises 
mainly from the faultiness of generic diagnoses there does not 
appear to be any escape from it, and I must therefore follow the 
same course that others have adopted and in some cases indicate 
a doubt as to the correctness of my generic determinations. 
Authors in general seem to be fairly agreed that the structure 
of the prosternum is the character on which the primary sub- 
division of the tribe should be founded. Dr. Chapuis (Gen. Col. 
vol. XI.) recognises two distinct forms of this structure indicated 
by the cavities of the front coxe being either open or closed
