following joints thickened and dilated, trigonate, the third 

 nearly twice as broad as long, its outer edge strongly com- 

 pressed, cariuate, the fourth and fifth nearly equal in length, 

 each rather shorter than the third, the upper and outer angle 

 of the fifth emarginate, bidentate. Thorax rather more than 

 one half broader than long ; sides nearly straight from the base 

 to the middle, thence slightly rounded and converging towards 

 the apex; disk transversely sulcate immediately behind the 

 middle, very distantly and minutely punctured, the puncturing 

 rather closer on the sides. Elytra oblong, dilated posteriorly, 

 convex, transversely excavated below the basilar space, finely 

 punctured. 



The three similarly coloured species described above are readily 

 separated in the male sex by the position and form of the frontal 

 tubercles. The females are not known to me.

Hah. New Guinea. 



Front on each side in the S with a strongly raised oblong 

 tubercle, placed longitudinally close to the inner margin of the 

 eye, apex of the tuberosity torulose, slightly incurved ; antennae 

 in the same sex with the basal joint thickened, its outer edge 

 concave-emarginate ; the third and two following joints dilated, 

 trigonate, the third and fifth equal in length and breadth, the 

 fourth longer than either of the two others, but less broadly 

 dilated; in the specimen before me, sent by Mr. Jacoby, the 

 outer half of the antennaD is stained with fuscous (the author 

 describes these organs as entirely flavous)*. Thorax nearly 



* The $ of this insect is unknown to me, the specimen sent by Mr. Jacoby 

 as belonging to that sex proving to be the of a similarly coloured species 

 having simple antennae.
