Phytophaga Malayana. 95 



I'ng the surface arranged in three longitiulinal rows, one on either 

 side broad and well defined, placed just within the lateral margin, 

 and a third, narrow and indistinct, occupying the middle of the 

 disk ; a few scales also scattered over the remainder of the surface. 

 Elytra much broader than the thorax, narrowed from behind their 

 middle, deeply impressed with parallel rows of punctures, from 

 each of which springs a single fine white hair ; interspaces to- 

 wards the apex and on the outer disk thickened ; scattered over 

 the whole surface are numerous white scales, wliich form irregular 

 confluent patches, more crowded towards the apex and on the 

 sides.

Elongatus, subcylindricus, obscure cupreus, subnitidus, squamis 

 adpressis albidis vestitus ; labro, antennarum basi, pedibusque 

 rufo-piceis ; thorace sulielongato, crebre et fortiter punctato, 

 vittis tribus e sq\iamulis forujatis instructo ; elytris fortiter 

 striato-punctatis, squamis disci hie illic irregulariter congre- 

 gatis. 



Long. 2 lin. 



Hab. Batchian. 



Head slightly longer than in the foregoing species, coarsely and 

 closely punctured ; epistome broadly but slightly angulate-emar- 

 ginate in front, thickened at the base, surface oblique, irregularly 

 strigose-rugose. Thorax longer than broad, sides obliquely di- 

 verging from the base to beyond the middle, thence rounded and 

 converging to the apex, above convex, closely and coarsely punc- 

 tured ; surface clothed with bifid scales, arranged in three longi- 

 tudinal rows, one on either side at the lateral margin, broad, 

 dilated in the middle and at the apex, where it is continued along 

 the anterior border of the thorax, and a third very narrovv and 

 indistinct, running down the middle of the disk. Elytra very 

 similar in form, puncturing and clothing to P. clypeatus, 



3. Pachnephorus conxexicollis, n. sp. 



Subelongatus, subcylindricus, obscure cupreus, subnitidus, 

 squamis albidis vestitus, labro antennarumque basi rufo-piceis; 

 thorace latitudine vix longiori, sat convexo, crebre et pro- 

 funde punctato, ad latera dense squamoso, disco fere glabro ; 

 elytris elongato-ovatis, fortiter striato-punctatis, pilis sub-
