Adelium pestiferum, n.sp, 

 (Plate iii., fig.6.) 



Narrow, elliptic, coppery-bronze, shining; oral organs, tarsi 

 and apical joints of antennae reddish. 



Head : labrum narrow, prominent, epistomal ridge pronounced, 

 frontal disc very concave, the whole coarsely and densely 

 punctured. Eyes large and widely elliptic. Antennae of male 

 long, with third joint a little less than fourth and fifth combined. 

 Prothorax broader than long (in the proportion of 7 : 10), sinuate 

 at apex, with anterior angles well advanced but obtuse, sides 

 widely rounded to meet the subrectangular and well defined hind 

 angles. Base truncate. Disc convex, separated fr< m foliaceous 

 sides by a short, deep, curved sulcus, whose continuation forward 

 is indicated by a second small fovea near front angle. Strongly, 

 but not rugosely punctured, with slightly raised vermiculate lines 

 irregularly placed. Medial line is indicated by slight depression. 

 (In one specimen this depression is only shown near base). Elytra 

 oval-elliptic, moderately convex, shoulders rounded. Widest in 

 anterior half, then gradually tapering (as in A. ellipticum Blackb.), 

 towards apex. Punctate-striate, with intervals strongly pustulated 

 with shining nodules. Abdomen and legs black, shining; posterior 

 intercoxal process rounded, truncate and entire. Anterior femora 

 slightly curved, other femora straight. Dimensions 13x5 mm.

This species belongs to the class of A. pustulosum Blackb., and 

 A. canaliculatum Carter. From the former it is readily distin- 

 guished by its lighter and unicolorous bronze, by its pronounced 

 hind angles to prothorax, and its more elongate-elliptic form; 

 from the latter it is more strongly differentiated by the shape of 

 prothorax (see Plate iii.), its larger size and brighter colour. It 

 is the most markedly pustulose Adelium known to me, the side 

 and apical portions being studded with shining nodules varying 

 in shape from round to elongate, the anterior central intervals 

 only being more or less smooth. The punctures in elytral striae
