ChALCOTHEA (PlECTRONe) VIRIDIPES. 



P. auripedi quoad formmn sindUima. Supra cum antennis et 



palpis saturate virifiis submetallica, svbtus pedibusque subaneo- 



viridis : clypeo profunde Jisso, capite utrinque marginato et 



punctata : thorace laferibus pwictaiis et marginatis ante medium 



perparvm angidatis deinde usque ad angulos posticos acutis fere 



rectis, medio cum scutello et elytrorum sutura late depresso : 



elylris prope marginem et ajncem pnnctulatis sub callo apicali 



siriffulosis. Pi-ocessus mesosternalis (equilaterali-triangidaris. 4 



cJ . Tibice onticee graciles,extus inermes ; posticcB intus longe ante 



medium lobum elongatum tenuem apice triangular iter spathu- 



latum emittentes. Ventris segmentum apicale apice medio emar- 



givatum. Pygidium transversim striatulum, apice convexum et 



medio sulcatum. 



$ . Tibice anticts Intte, tridentatce ; postice inermes, calcari inte- 



riore elongato apice emarginato. Ventris segmentum apicale 



semicirculare, toto transversim striolatum. Pygidium striatum, 



apice parum convea'um, cequale. Long. 34 millim. 



This species is similar in colour to Clerota brama (Gestro), to 



wliich I should have been inclined to refer it, if the niesosternal process 



had not been so different in form. In C. brama it is prolonged (as 



figured in ' Midden-Sumatra,' iv. 6, pi. ii. fig. 55) 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. brama than in C. viridipes. 



Chalcothea (Plectrone) spathulifera.
