NEW PHYTOPHAGOUS COLEOPTERA 65 



tured , the interstices being slightly uneven and that the frontal 

 tubercles are very distinct (nari'owly transverse) ; in the type 

 the latter are obsolete and almost wanting; these two differences 

 are however the only ones I can find and I think may be taken 

 as the result of local variation, M.^' Raly's specimen having been 

 obtained at Batchian. 



Oblong, fulvous; head thorax and legs black; three apical 

 joints of the antennae and t\u) posterior tarsi, testaceous; thorax 

 impunctate, elytra very minutely punctured.

Head impunctate, black; fr(\ntai tubercles indistinct; labrum

 colour; antennae nearly as long as the body, slender, the 3.*^ 

 joint one half longer than the 2.''; the eight lower joints black, 

 the rest testaceous; thorax nearly squareshaped ; the sides slightly 

 rounded and forming a distinct angle at the middle; anterior 

 angles oblique, posterior produced in a short tooth; surface shi-

 tarsi testaceous. 



Sumatra, Mt. Singalang (0. Beccari). 



This species differs from its numerous allies in the long an- 

 tennae and angulate sides of the thorax; other structural diffe- 

 rences I cannot however find and I included it therefore in the 

 present genus. 



V. Thorax with transverse groove, anterior cavities closed.
