388 MR. H. W. BATES ON NEW COLEOPTEROUS [June 18, 
CHALCOTHEA (PLECTRONE) VIRIDIPES. 
P. auripedi quoad formam simillima. Supra cum antennis et 
palpis saturate viridis submetallica, subtus pedibusque subeneo- 
viridis: clypeo profunde fisso, capite utrinque marginato et 
punctato: thorace lateribus punctatis et marginatis ante medium 
perparum angulatis deinde usque ad angulos posticos acutis fere 
rectis, medio cum scutello et elytrorum sutura late depresso: 
elytris prope marginem et apicem punctulatis sub callo apical 
strigulosis. Processus mesosternalis equilaterali-triangularis. & 
3. Tibie antice graciles,extus inermes ; postice intus longe ante 
medium lobum elongatum tenuem apice triangulariter spathu- 
latum emittentes. Ventris segmentum apicale apice medio emar- 
ginatum. Pygidium transversim striatulum, apice convexum et 
medio sulcatum. 
Q. Tibie antice late, tridentate ; postice inermes, calcari inte- 
riore elongato apice emarginato. Ventris segmentum apicale 
semicirculare, toto transversim striolatum. Pygidium striatum, 
apice parum converum, equale. Long. 34 millim. 
This species is similar in colour to Clerota brama (Gestro), to 
which I should have been inclined to refer it, if the mesosternal process 
had not been so different in form. In C. drama it is prolonged (as 
figured in ‘ Midden-Sumatra,’ iv. 6, pl. ii. fig. 54) into an acute point ; 
in C. viridipes it forms a rather short subequilateral triangle. The 
hind legs and tarsi, judging from the figure, are also much shorter 
in C. drama than in C. viridipes. 
CHALCOTHEA (PLECTRONE) SPATHULIFERA. 
Precedentibus differt thorace scutello basique elytrorum parum 
depressis his post medium planis: supra saturate cenescenti- 
viridis, antennis et palpis castuneo-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, elypeo triangulariter 
emarginato lobisque minus acuminatis, toto crebre punctato 
carinisque submarginalibus angustis. Thorax angustior longe 
ante medium subangulato, deinde postice margine usque ad an- 
gulos posticos acutos valde sinuato : scutello levi: elytris disco 
utrinque viv convexis.  Subtus et pedes sat dense punctata, 
medio fere levis.  Pygidiwm dense transversim rugulatum. 
Processus mesosternalis mediocris, apice obtuse acuminatus. 
3. Tibie antice extus inermes, intermedie intus valde sinuate 
apiceque dilatate, postice intus longe ante medium lobo longis- 
simo tenui apice spathuliformi (ovato) armatis: venter disperse 
punctulatus parum depressus, segmento apicali apice valde et late 
sinuato. Pygidium apice breviter bilobatum. 
9. Tibie antice tridentate, intermedia recte calcaribus acutis, 
postice recte calcart interiore elongato, apice emarginato.
