A very dark specimen from Mt. Poi, 4000 feet, I refer 

 without hesitation to this species. 



Plater OS expressus n. sp. 



Dark brown, only the mar<Tin of elytra and sometimes 

 prothorax yellowish, moderately shining; elytra with dense 

 and lonsf hairs. Frons in cf ^^^ hroad as 

 the diameter of the eye ; in 9 broader, 

 slightly impressed, hairy ; antennae in cf 

 dentate, in 9 more slender, simple. Pro- 

 thorax in cf a little broader than lonj?, 

 anterior margin rounded, protruding:, 

 anterior angles indistinct, the sides and 

 posterior margin more or less straight, 

 posterior angles rectangular, the basal 

 impression short., only the margins punc- 

 tured ; in 9 more rectangular. Scutel- 

 lum at the extreme tip slightly sinuate. 

 Elytra with distinct ribs and square 

 reticulation. 



Length of body, 5 mm. Width (hu- 

 merus) 1.5 mm. 'Mt. Poi. 1500-2000 feet. 



Typus in Sarawak Museum and cotypus in my collections. 



The new species is easily separated from already described 

 ones by its coloration. The lighter coloured parts of elytra 

 stand out immediately from the darker parts, only at the lateral 

 margin the dark colour approaches the basis. The shape of 

 penis (fig. 2) distinguishes it directly from other species.
