 varied with purple, brassy and golden tints, the sides of the pro- 

 meso- and meta-sterna and abdominal segments clothed with large 

 fulvous patches ; the prosternal point is also fulvous, except at its 

 deflexed obtuse extremity. The legs are black, with a purple 

 gloss ; the four posterior tibiae with a coat of short black hairs on 

 the outer edge beyond the middle, the surface of this part of 

 these limbs being marked with a remarkable series of fine oblique 

 striae. 



I have only seen a single specimen of this very beautiful and 

 singular Longicorn in the rich collection of Philippine insects 

 collected by Mr. Semper, and now in the possession of his 

 brother, G. Semper, Esq., of Altona, to whom my thanks are 

 especially due for entrusting me with the loan of this and several 

 other equally interesting unique insects.

Subdepressed ; moderately shining, head and thorax almost 

 impunctate, the elytra strongly punctured at the base. The head 

 is black, with two fulvous spots on the face, and two larger ones 

 behind the antennae ; the antennae are inserted far apart at the 

 lateral anterior angles of the head, the face is quadrate, the lip 

 and mandibles black ; the antennae are about the length of the 

 body, with the intermediate joints clothed with white hairs at the 

 base ; the prothorax is transverse, convex, the sides destitute of 

 spines, the anterior margin slightly narrowed, and the posterior 

 margin finely constricted ; on each side is an irregular circle of 

 white pile, and in the middle, near the hind margin, are two oval 

 white spots. The elytra are much wider than the prothorax at
