150 Phyiojyhaga Malayana. 



third of tlie elytron ; interspaces strongly thickened, costate ; on 

 the anterior two-thirds the costae are much broken up and inter- 

 rupted through the coarse irregular reticulations of the surface, 

 on the hinder third they are more or less vermiculate. Thighs 

 simple. 



Nearly allied to C. tuberculata, but separated from that species 

 by the absence of tubercles on the elytra ; it is also very close to 

 C. Laportn (p. 148), but may be known by the less strongly raised 

 costae on the hinder third of the elytra. 



24. Colaspoides tuberculata, n. sp. 



Ovata, convexa, viridi-aenea, supra senea aut cupreo-aenea ; 

 antennis filiformibus, purpureo-nigris, basi fulvis, seneo- 

 tinctis ; thorace distincte punctato ; elytris fortiter seriatim 

 punctatis, interspatiis ad apicem costatis ; punctis disco ex- 

 teriori confuse dispositis, interspatiis valde elevatis, irregu- 

 lariter reticulatis, tuberculatis. 



Long. 2| lin. 



Hab. Borneo (Sarawak). 



Head deeply but distantly punctured, upper portion of the front 

 impressed with a deep longitudinal groove ; epistome triangular, 

 sides slightly rounded, extreme apex continuous with the lower 

 border of the face; surface deeply but remotely punctured, its 

 lower portion obliquely deflexed, anterior border produced into 

 two very short obtuse lobes ; supra-ocular groove broad, deep, 

 extending downwards of equal depth between the encarpse and 

 fiice ; antennae slender, filiform, neatly equal to the body in length, 

 three or four lower joints obscure fulvous, metallic-green above. 

 Thorax transverse, sides nearly straight and parallel behind the 

 middle, obliquely rounded and converging from the middle to the 

 apex ; surface deeply but not very closely punctured. Elytra 

 broadly oblong, convex, deeply punctured, the punctures arranged 

 in longitudinal rows at the base, on the inner disk, and on the 

 hinder third of the outer disk ; the interspaces on the hinder third 

 of the whole surface costate ; on the anterior two-thirds of the 

 outer disk the punctures are less regularly arranged, the inter- 

 spaces being strongly thickened, irregularly reticulated and broken 

 up into numerous irregular tubercles. 



C. tuberculata is most nearly allied to C. cognata, but may be 

 separated by the tuberculate interspaces of the elytra.
