Phytophaga Malayana. 87 



Head opake, clothed with the usual white scales, epistome 

 broadly wedge-shaped ; eyes large, prominent, nigro-piceoiis. 

 Thorax not broader than long, subcylindrical, slightly gibbous on 

 the disk, sides rounded, converging from the middle to the apex. 

 Scutellum truncate, nigro-piceous. Elytra indistinctly depressed 

 below the basilar space, the latter obsoletely elevated; deeply and 

 coarsely punctured, the punctures arranged in longitudinal rows, 

 their interspaces thickened and elevated ; shoulders somewhat 

 prominent ; scales covering the surface rather longer and slightly 

 less adpressed than those on the head and thorax, arranged in ill- 

 defined longitudinal rows, more crowded here and there, and 

 forming small irregular patches on the surface. 



5. Demolina grisea, n. sp. 



Oblonga, convexa, nigro-picea, subnitida, sat dense albo-sqna- 

 mosa; thorace latitudini sequilongo, rugoso-punctato, ad latera 

 rude rugoso, lateribus rotundatis, ante medium convergenti- 

 bus ; elytris fortiter striato-punctatis; epistomate cuneiforme; 

 antennis, tibiis apice, tarsisque rufo-piceis. 



Long. Ig lin. 



Hab. Sarawak. 



Head clothed- with adpressed scales ; epistome wedge-shaped, 

 longer than broad, distinctly separated from the face by a deep 

 sutural groove ; eyes large, prominent ; basal joints of antennae 

 fulvous. Thorax transversely convex above, slightly flattened on 

 the disk ; surface rugose-punctate. Elytra coarsely striate-punc- 

 tate, somewhat closely clothed with adpressed scales, which are 

 distributed nearly equally over their whole surface. 



This species may be known from D. rugicollls by the absence 

 of teeth on the lateral margin of the thorax, by the larger wedge- 

 shaped epistome, and by the more equal distribution of the scales 

 over the surface of the elytra. 



G. Demolina JVallacei, n. sp. 



Oblonga, convexa, picea, subnitida, dense albo-squamosa ; 

 thorace longitudine vix latiori, subcylindrico, ante apicem 

 transversim depresso, rugoso-punctato ; elytris infra basin
