side; maxillary palpi widely, labial palpi very widely securifurm, 

 penultimate joint of labial palpi short, stout : protliorax parallel 

 on sides, lobate : anterior angles prominent ; two marginal 

 setigerous punctures on each side : elytra not perceptibly wider 

 than prothorax, depressed on disc, impunctate: humeral angles 

 shortly dentate: inflexed margin narrow behind first ventral 

 segment : anterior tibise bidentate. Nitid, head black, with 

 bright green reflections on frontal lateral spaces, across occiput, 

 in transverse impression, and on sides of guise: prothorax black, 

 with wide bright green lateral margins becoming aeneous at pos- 

 terior curve: elytra bright green, purple-black on disc (along 

 suture) and narrowly along basal, lateral, and apical margins: 

 inflexed margin black with faint greenish tinge: undersurface 

 and legs black: pro-episterna and ventral segments 3-6 with 

 viridescent tints. 



Head large (3-3 mm. across eyes), convex, constricted behind 

 eyes; frontal spaces convex, middle space filling all thc' interval 

 between frontal sulci, its posterior margin strongly defined by a 

 transverse impression, lateral spaces narrow and strongly raised 

 behind, defined externally foi- length of eyes by a deep supra- 

 ocular sulcus; labrum small; clypeus roundly declivous, median 

 part obsoletely trisinuate, intermediate angles short, obtuse: 

 submentum strongly raised from guise, foveate on each side 

 behind gente. Prothorax as long as broad (3-35 x 3"35 mm.), 

 convex, declivous to basal sinuosities; sides parallel, rounded at 

 posterior angles, strongly sinuate on eacli side of basal lobe : 

 antei'ior margin truncate, anterior angles advanced, bordered; 

 border very narrow. Elytra of about same width as piothorax 

 (6-5 X 3-4 mm.), subparallel on sides, depressed on disc, strongly 

 and roundly declivous on sides; suture strongly impressed: 

 border narrow, thickened towards apex, upturned in a short, 

 subacute process at humeral angles ; a closely placed row of 

 punctures along sides ; about six punctures on base of each 

 elytron (five in a transverse row, the remaining one placed before 

 this row towards lateral border). Ventral segments 3-0 bipunc- 

 tate. Anterior tibiae strongly bidentate; apical plate without a 

 subdentiform prominence below tarsus. Length, 13; breadth,
