Length 18 mm., breadth at the shoulders 6^3 ram.; length 

 of the antennae 41 mm. — Head dark brown, covered with a 

 reddish brown pile in front , changing on the vertex in 

 stripes of different colours, varying from blackish brown 

 to yellowish. The front with a prominent longitudinal 

 line; the mandibles black. The scape of the antennae and 

 the 2"'i joint black with a greyish tomentum , all the 

 other joints fulvous , becoming darker near the apices. 



Prothorax nearly as long as wide at the base , with a 

 strong lateral tooth on each side ; at the top and at the 

 base transversely impressed ; on the disk with some small 

 gibbosities: covered with a blackish-brown velvety shining 

 pile in the middle, laterally with patches of different shades ,

Elytra straight at the base, gradually attenuated towards 

 the apex , slightly convex ; the shoulders rounded ; deeply but 

 distantly punctured, strongest at the base; the apical half 

 of each elytron with two elevated lines ; each elytron rounded 

 separately at the end. — Brown , darkest at the base, covered 

 with a pubescence of a lighter shade , lightest in the middle 

 where it is intermixed with numerous very small punctiform 

 and strigiform spots. The base near the shoulders is covered 

 with the continuation of the pile that covers the sides of 

 the thorax. Each elytron shows at two thirds of its length, 

 near the lateral margin , three oval white spots , placed in 

 a triangle , and another one near the apex. 



The whole underside and the legs with a close pubes- 

 cence of various shades, the brown being dominent at the 

 prosternum and abdomen , the white and ochraceous at the

A single cf specimen of this beautiful species was 

 captured in Sumatra, and I am glad to have the op- 

 portunity to name this insect in honour of Dr. J. C. Costerus , 

 who always kindly favours me with the insects he receives.
