Phytophaga Malayana. 59 



interspaces forming close elevated reticulations ; gibbosity im- 

 pressed with a broad, shallow, longitudinal groove, wliicli, distinct 

 at its base, is gradually lost on the anterior portion of the gibbosity. 

 Elytra rugose-punctate, the interspaces along the middle of the 

 disc forming four or five irresjular longitudinal ridges : each 

 elytron furnished with a number of elevated tuberosities ; those 

 on the anterior half of the disc transversely compressed, those near 

 the apex more strongly raised and irregular in shape, their surface 

 covered with large round reticulations : these tuberosities are 

 placed as follows, viz. the first at the lower edge of the basilar 

 space, half-way between the suture and humeral callus; the 

 second about the middle of the length of the elytron, placed 

 obliquely half-way between the first tubercle and the suture ; the 

 third on the suture itself, at some little distance below its middle ; 

 these three form an oblique line across the disc ; secondly, three 

 other tuberosities, placed respectively a little more outwardly and 

 lower down than the three preceding, form another oblique line, 

 parallel to the former ; and, lastly, there are two or three 

 tuberosities on the apical portion of the disc, more towards the 

 outer angle.

Head closely punctured ; antennae obscure fulvous, pale piceous 

 towards the apex. Thorax strongly gibbous, surface of gibbosity 

 oblique posteriorly, covered with six raised lines ; the middle 

 pair parallel, not united at their base, anastomosing in front with 

 each other and with the intermediate pair ; the four others oblique, 

 arising two on either side from the middle lines, the outer pair 

 short. Elytra more coarsely punctured than the thorax, sub- 

 parallel, slightly narrowed towards their apex ; shoulders promi- 

 nent ; disc of each elytron furnished with four indistinct longitu- 

 dinal ridges ; the first rises at the base near the scutellum, runs 

 parallel to the suture, is slightly elevated in the middle of its 

 course, and terminates at a short distance below the middle of 

 the disc in a strongly raised, transversely compressed tubero-
