the lower lobes extended close to the rnandibular edge of thegenae ; 

 mandibles oblique, straight at base, turned in at right angles at 

 the apex. Antennae of c? about one-third to twice longer than 

 the body ; first joint stout, asperate, its apex with sharp upper 

 edge and acutely produced anterior angle or spine ; third to tit'th 

 thickened, asperate, the third shorter than the fourth or fifth ; 

 sixth to tenth subequal, each much shorter than the fifth ; antenna) 

 of $ a little longer than the body, joints third to fiffh less 

 thickened and less asperate. Prothorax slightly convex above, 

 rounded at the sides, base with rounded lobe in the middle. 

 Elytra long, more or less narrowed backwards from the base, 

 rounded at the apex. Legs long, the front pair shorter than the 

 others ; femora fusiform-clavate, compressed, pedunculate at base ; 

 tibiae compressed. Front coxae separated, their acetabula strongly 

 angulate outwards. Mesosternum moderately broad, narrowed 

 posteriorly and truncate at the end. 



The pupa3 of one species at least, and probably of all the species, 

 of this genus are enclosed in calcareous cocoons of a texture 

 similar but somewhat longer and narrower in form than those 

 which enclose the pupae in the genus Plocederus.

Eeddish brown ; protborax with the front and hind borders, a 

 narrow median longitudinal band (sometimes obsolete) and a 

 broader lateral band, which in the c? 

 runs obliquely from the side of the 

 thorax in front towards the medio-basal 

 lobe behind, metallic blue or green ; 

 elytra testaceous yellow, the outer and 

 apical borders and, on each, a median 

 longitudinal band, which anteriorly is 

 directed obliquely towards the shoulder, 

 also metallic blue or green. Head densely 

 punctate. First joint of antennae 

 asperate, with spiniform anterior process 

 at the apex ; third to fifth strongly 

 asperate, each in the 6* with the apex 

 thickened and dentate beneath ; third 

 joint thicker and about one-fourth 

 shorter than the fourth. Prothorax 

 densely and finely granulated on the 

 disc in the d" , less densely granulated in 

 the $ ; prosternum of the male with a transversely striated glossy 

 band of metallic colour, close to the front margin, the rest of its 

 surface as well as the lower part of the sides of the prothorax 

 forming a convexly raised, very minutely and densely punctate, 

 area of a dull red colour; the corresponding area in the female more
