90 Phytophaga Malayana. 



lateral margins, where sometimes they form an ill-defined longi- 

 tudinal vitta. Elytra deeply and coarsely striate-punctate, sub- 

 nitidoLis, interspaces on the middle of the disk raised and forming 

 indistinct transverse ridges, scales clothing their surface collected 

 into irregular ill-defined patches. 



10. Demotina rufopicea, n. sp. 

 Oblonga, subcylindrica, rufo-picea, subnitida, albo-squamosa ; 

 thorace latitudini aequilongo, subcylindrico, rugoso-punctato; 

 elytris profunde striatim punctatis, interstitiis elevatis, squamis 

 hie illic congregatis, plagas albidas formantibus ; epistomate 

 cuneiforme. 

 Long. 1^ lin. 

 Hab. Menado. 



Head clothed with coarse adpressed scales ; epistome wedge- 

 shaped, not distinctly separated from the face, its surface glabrous; 

 eyes large, prominent. Thorax subcylindrical, sides converging 

 in front ; surface coarsely rugose-punctate, clothed with adpressed 

 whitish scales. Elytra coarsely and deeply striate-punctate, the 

 interspaces thickened, scales on the surface arranged in irregular 

 patches. 



Very nearly allied to D. parvula, and very possibly only a 

 variety of that insect ; it differs chiefly in the coarser punctation 

 of the elytra. 



11. Demotina ornata, n. sp. (Pi. IV. fig. 8.) 



Oblonga, convexa, nigra, nitida ; tibiis apice, tarsis, antennis 

 (his extrorsum piceis), epistomate labroque fulvis; thorace 

 vittis duabus, elytrisque maculis nonnullis e squamis albis 

 formatis ornatis.

Hab. Ceram. 



Head coarsely punctured ; face clothed on either side within 

 the eyes with adpressed white scales ; antennae slightly thickened 

 towards the apex, slender, two-thirds the length of the body, pale 

 fulvous, six outer joints piceous. Thorax scarcely broader than 

 long, subcylindrical, sides slightly rounded, converging in front; 

 surface closely covered with large round shallow punctures, spar- 

 ingly clothed with white scale-like hairs, either side of the disk 

 with a broad longitudinal vitta of adpressed white scales. Elytra 

 striate-punctate, sparingly clothed with white scale-like hairs;
