Phytophaga Malayana. 75 



angles produced distinctly backwards, anterior angles produced 

 into an acute tooth ; basal margin subsinuate, on either side 

 slightly oblique near the medial lobe, the latter very slightly 

 produced, its apex broadly truncate ; above transversely convex, 

 strongly impressed with large deep punctures ; the piceous 

 colour (in the unique specimen before me) covers nearly the 

 whole surface, leaving only the outer limb and a few small mark- 

 ings on the front and sides flavous. Scutellum transversely 

 quadrate, its sides sinuate, its apex broadly truncate, the basal 

 margin, together with those of the thorax and elytra, narrowly 

 edged with black. Elytra distinctly narrowed from their base 

 towards the apex, sides moderately lobed at their base ; upper 

 surflice thickened near the scutellum, deeply impressed with 

 numerous large round punctures, which, placed without order on 

 the anterior disc, form irregular longitudinal rows towards the 

 apex of the elytron ; interspaces thickened, transversely rugulose 

 in front and on the sides, costate on the hinder disc ; the surface 

 of the disc is almost entirely piceous, the suture and a few smooth 

 irregular slightly raised scattered patches being flavous.

Hab. Morty Island. 



Head coarsely rugose-punctate ; eyes reniform, their inner 

 edge deeply notched ; antennae slender, filiform, basal joint 

 thickened, second moderately thickened, short, ovate, third 

 slender, filiform, three times the length of the second, fourth equal 

 in length to the third ; basal joint fulvous, the two following rufo- 

 piceous, the next two black (the others wanting). Thorax twice 

 as broad at the base as long ; sides rounded, slightly converging 

 in front, the lateral border reflexed ; basal margin broadly concave 

 on either side, slightly produced near the medial lobe, the latter 

 broadly truncate, its margin slightly excavated to receive the base 

 of the scutellum ; upper surface very convex and obsoletely
