74 Phytophaga Malayana. 



Head semicircular, flat, front impressed with a longitudinal 

 groove ; jaws and eyes black, the latter large, flat, their inner 

 edwe deeply notched ; antennae three-fourths the length of the 

 body, very slender, filiform ; basal joint moderately thickened, 

 second short, ovate, third about one-half longer than the second, 

 fourth and three following nearly equal, each about one-half 

 longer than the third, eighth and following joints gradually dimi- 

 nishing in length. Thorax twice as broad at the base as long ; 

 sides obliquely deflexed from base to apex, nearly parallel at 

 their base, rounded and converging in front ; basal margin 

 slightly concave on either side ; medial lobe not produced, its 

 margin concave, emarginate ; above very convex, almost gibbose 

 in front, smooth aud shining, impunctate ; on either side, just 

 in front of the base, is a broad obliquely transverse depression, 

 which, extending from the medial line nearly to the middle of 

 the lateral margin, renders the convexity of the anterior disc very 

 apparent. Scutelluni narrowly trigonate, shining black, its apex 

 subacute. Elytra nearly three times the length of the thorax, 

 parallel, sides moderately lobed at their base, not thickened in 

 the region of the scutellum, the humeral callus moderately pro- 

 minent ; each elytron with eleven rows of regularly-placed, deep, 

 but not very large punctures, which become smaller towards the 

 apex ; interspaces plane, very slightly convex on the outer disc. 

 Body beneath sparingly clothed with concolorous adpressed hairs. 

 Anal segment of abdomen in the ? with a large deep round fovea. 

 Prosternum longer than broad, its hinder extremity produced into 

 two very obtuse teeth.
