72 Phytophaga Malayana. 



cave, upper surface very convex, subglobular in front, smooth and 

 shining, very fine punctures placed at distant intervals being 

 visible only under a lens ; at the base on either side, just in front 

 of the medial lobe, is a somewhat oblique large shallow fovea ; the 

 extreme edge of the basal margin black. Scutellum forming an 

 elongated triangle, its apex obtuse, basal margin notched in the 

 middle, edged with black. Elytra parallel, slightly lobed at the 

 base ; upper surface convex, thickened round the suture, smooth 

 and shining, finely and regularly punctate-striate ; the punctures 

 small, piceous ; interspaces smooth, plane ; on each elytron are 

 placed eleven of these rows, the first being short.

 Long. 2 lin. 

 Hab. Borneo. 



Head rotundate, face flat, front with a slight longitudinal im- 

 pression ; epistome trigonate ; eyes long, black, their inner edge 

 broadly notched ; antennae filiform, nearly equal to the body in 

 length ; first joint incrassate ; second short, ovate ; third and 

 fourth equal, each twice the length of the second ; fifth and fol- 

 lowing joints also equal, slightly compressed and also dilated, 

 each rather longer than the fourth. Thorax about twice as broad 

 at the base as long ; sides moderately rounded and obliquely con- 

 verging from base to apex, hinder angles produced slightly back- 

 wards ; basal margin truncate, its medial lobe not produced ; 

 above very convex, subcylindrical in front, surface smooth and 

 shining, entirely free from punctures or impressions of any kind ; 

 the extreme basal margin narrowly edged with black. Scutellum 

 trigonate, its apex rounded. Elytra convex, sides moderately 

 lobed at the base, not narrowed posteriorly ; upper surface 

 sliglitly thickened in the neighbourhood of the scutellum ; humeral 

 callus obtuse, slightly prominent ; each elytron with eleven rows 

 of regularly placed punctures, which nearly disappear towards the 

 apex ; interspaces smooth, raised into faint transverse rugae on the 

 anterior disc, plane over the rest of the surface; on each interspace 

 is an irregular row of very minute punctures.
