Chalcothea (Plectrone) spathulifera. 
Praecedentibus differt thorace scutello basique elytrorum parum depressis his post medium planis : 
supra saturate senescenti-viridis, antennis et palpis castaneo-cupreis clava obscura, corpore subtus 
femoribusque cupreo-auratis, tibiis, tarsis clypeoque apice igneo-cupreis ; supra toto sat dense 
punctata, elytris basi sparsius et seriatim, lateribus et apice confluenter et rugose, punctatis, 
interstitiis subtilissime punctatis. Oculi magni et prominentes, capite ante oculos angusto 
antice dilatato, clypeo triangulariter emarginato lobisque minus acuminatis, toto crebre punctato 
carinisque submarginalibus angustis. Thorax angustior longe ante medium subangulato, deinde 
postice margine usque ad angulos posticos acutos valde sinuato : scutello laevi : elytris disco 
utrinque vix convexis. Subtus et pedes sat dense punctata, medio fere laevis. Pygidium dense 
transversim rugulatum. Processus mesosternalis mediocris, apice obtuse acuminatus. 
$. Tibiae anticae extus inermes, intermediae intus valde sinuatae apiceque dilatatae, posticae intus 
longe ante medium lobo longissimo tenui apice spathuliformi (ovato) armatis : venter disperse 
punctulatus parum depressus, segmento apicali apice valde et late sinuato. Pygidium apice 
breviter bilobatum. 
? . Tibiae antics? tridentata > , intermediae recta? calcaribus acutis, posticae rectae calcari interiore 
elongato, apice emarginato. Pygidium apice planum. Yentris segmentum apicale apice obtuse 
rotundatum, strigosum. Long. 32 millim. 
Chalcothea affinis, Vollenh. Tijdschr. Nederl. Ent. Yer. i. p. 23, t. ii. fig. 2 ( d'). 
Mr. Whitehead obtained female examples only, in which the mesosternal process is extremely short 
and far from semicircular as described by Yollenhoven. I have, however, seen another example ( ? ), 
from Borneo (probably Sarawak), differing in no other respect from these two than in the mesosternal 
process being nearly semicircular. The sides of the thorax are immarginate. 
Chalcothea pomacea. 
$ . C. resplendenti quoad formam similis, paullo robustior, toto pomaceo-viridis subargenteo-relucens, 
subtus medio tantum subflavescens, tarsis chalybeis ; supra medio fere a collo usque apicern 
latius et profundius quam in C. resplendente concava ; supra et subtus Isevissima, capite thora- 
cisque lateribus parce punctatis, elytrisque prope marginem et apicern 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 hand angulatim dilatato, postice minus oblique sinuato-dilatato, angulis posticis perparum 
extus productis, margine laterali integro. Processus mesosternalis brevis, rotundato-sub- 
acuminatus vel semiovatus. Yentris segmentum apicale apice medio obtuse rotundatum, 
strigulatum et setifero-punctatum. Tibiae posticae 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 planiuscttla. 
$ . Dilutius pomaceo-viridis, submetallico-nitens, capite viridi-ameo, antennis palpisque rufis, tibiis 
et tarsis fulvis laete 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 apicern fere planis ; thorace anguste trapezoidali, 
angulis posticis parum productis, lateribus paullulmn flexuosis fere rectis, sulco marginali pro- 
fundo passim minutissime dense punctulato, punctis paullo majoribus consperso, lobo basali 
minus producto, scutelloque elongato : elytris lateribus et apice sat dense punctatis, disco 
utrinque convexo lasvi. Pygidium dense transversim striatum. Processus mesosternalis brevis- 
simus, antice rotundatus. Subtus medio lasvis, lateribus et pedibus disperse punctatis. Yentris 
segmentum apicale strigulosum, apice rotundatum. Tibiae posticae calcari interiore apice 
emarginato-truncato. Loner. 30 millim. 
A single (female) example. 
Glyptothea, nov. gen. 
A gen. Chalcothea differt clypeo apice verticaliter reflexo integro. Oblongus ; thorace postice, 
scutello elytrisque medio profunde depressis, his disco posteriore lateribusque plurisulcatis :
