Pygidium apice planum. Ventris segmentum apicale apice 
obtuse rotundatum, strigosum. Long. 32 millim.

Pacaptat. fe. 2 (3"). 
Mr. Whitehead obtained female examples only, in which the 
mesosternal process is extremely short and far from semicircular as 
described hy Vollenhoven. I have, however, seen another example 
(2), from Borneo (probably Sarawak), differing in no other respect 
from these two than in the mesosternal process being nearly seimi- 
circular. The sides of the thorax are immarginate. 
CHALCOTHFA POMACEA. 
Q. C. resplendenti quoad formam similis, paullo robustior, toto 
pomaceo-viridis subargenteo-relucens, subtus medio tantum sub- 
Jlavescens, tarsis chalybeis ; supra medio fere a collo usque apicem 
latius et profundius quam in C. resplendente concava ; supra et 
subtus /evissima, capite thoracisque lateribus parce punctatis, 
elytrisque prope marginem et apicem plagis duabus strigosis, callo 
humerali valde convexo nigro, callo apicali parum elevato : capite 
elongato, angusto, antice parum dilatato, apice triangulariter fisso: 
thorace elongato et angusto, ante medium perparum et haud angu- 
latim dilatato, postice minus oblique sinuato-dilatato, angulis 
posticis perparum extus productis, margine laterali integro. 
Processus mesosternalis brevis, rotundato-subacuminatus vel semi- 
ovatus. Ventris segmentum apicale apice medio obtuse rotund- 
atum, strigulatum et setifero-punctatum. Tibie postice calcari 
interiore apice oblique truncato. Long. 30 millim. 
A single female example. May possibly be found to belong to 
the section Plectrone when the male is known. The margined sides 
of the thorax would bring it, like the following, within the definition 
of Ritsema’s genus Pseudochalcothea, which appears to be synonymous 
with Plectrone, all the species of which that I have seen have the 
thorax similarly margined. 
CHALCOTHEA PLANIUSCULA. 
Q . Dilutius pomaceo-viridis, submetallico-nitens, capite viridi-eneo, 
antennis palpisque rufis, tibiis et tarsis fulvis lete aureo- vel 
cupreo-metallicis : capite ante oculos sat brevi, quadrato, apice 
minus angulatim profunde emarginato, passim punctato ; thorace, 
scutello et elytris medio late et parum profunde depressis, his 
longe ante apicem fere planis ; thorace anguste trapezoidali, angulis 
posticis parum productis, lateribus paullulum flexuosis fere rectis, 
sulco marginali profundo passim minutissime dense punctulato, 
punctis paullo majoribus consperso, lobo basali minus producto, 
scutelloque elongato: elytris lateribus et apice sat dense punctatis, 
disco utrinque convexo levi. Pygidium dense transversim striatum. 
Processus mesosternalis brevissimus, antice rotundatus. Subtus 
medio levis, lateribus et pedibus disperse punctalis. Ventris
