356 Longicornia Malayana. 



ferently sliaped from that of the type. Both species are thinly 

 covered with short stiffish erect hairs. 



Cyanastus aiilicus. (PI. XVI. fig. 2.) 



C. fulvus, elytris laete cyaneis ; prothorace valde transverse, 



antice miilto angustiore. 

 JIab. — Macassar. 



Fulvous, shining, elytra bright glossy blue, blackish and opaque 

 on each side behind the shoulders ; head and prothorax finely 

 punctured, each puncture furnished with a stiffish erect hair, base 

 of the antennary tubers and sometimes the middle of the prothorax 

 spotted with black ; scutellum semicircular, yellow ; elytra finely 

 punctured, clothed with short erect hairs, especially at the sides; 

 body beneath and legs yellow, hairy, the tibiae and tarsi blackish 

 or blueish ; antennae yellowish, the outer side of the basal joints 

 and apex blackish. 



Length 7 lines. 



Cyanastus simius. 



C. fulvus, elytris laete cyaneis ; prothorace modice transverse, 



antice vix angustiore. 

 Hab. — Menado. 



Differs from the former in the narrower prothorax, the apex 

 and base nearly of the same breadth, and the lateral tumidity very 

 much smaller ; the elytra also are less convex. 



Tropimetopa. 



Tropimetopa, J. Thomson, Syst. Ceramb. p. 118. 



Characteres ut in Aslathe, sed caput antice inter oculos bicarina- 

 tum ; elytra depressa, breviuscula, ampla, baud carinata, 

 apicibus spinosis. 



M. J. Thomson separated this genus from Hecphora (or as it 

 should be written Ecphora) on account of the presence of two 

 frontal ridges — one at the base of each antenna — and the de- 

 pressed spined elytra. The former character, however, is found, 

 although in a less degree, in Ecphora testator (an African species). 

 Still, when we take into account the gibbous prothorax of Ecphora, 

 prolonged posteriorly so as nearly to cover the scutellum, and 

 contrast it with that oi Tropimetopa, whicli is nearly of the same 

 form as in Astathes, we cannot hesitate to adopt the genus.
