Waterh., astula Ent, ii. 1877, p. 201. 



Caenxleus, nitidus ; thoraco vix brevissime pubescentc ; disco lon- 

 gitudinaliter fortiter impresso, lateribus biimpressis ; elytris piceo- 

 testaceis, dense fulvo-rufo-pubescentibus, striis vix perspicue im- 

 pressis, apice anguste nigro ; antennis pedibusque violaceis.

Hah. Java {6), Penang ( $ ) (J. C. Bowring, Esq.). 



A more slender species than any of the preceding, and rendered 

 distinct by the beautiful shining blue thorax and violet antennae. 

 The anterior angles of the thorax are much dcflexed, and conse- 

 quently do not show the margin so distinctly ; the disk has not a 

 fine mesial line, but a deep longitudinal impression ; the lateral 

 fossfB are deep, but the oblique ridge which divides them is not so 

 well defined as in most of the species. 



c? . AntenufE rather slender. Elytra with scarcely any trace of 

 costse. Penultimate segment of the abdomen with a deep incision. 



2 . Antenn?e very slightly dilated. Thorax more narrowed in 

 front. Elytra bicostate. 



The two examples in the collection are from different localities, 

 but there is no doubt that they should he associated as sexes of the 

 same species. 



Calochromus longipennis.

Elongatus, subparallelus, niger ; thoraco supra piceo, dense rufo- 

 pubescente, medio foveola lanceolata impresso, lateribus biimpressis ; 

 scutello piceo, rufo-pubescente ; elytris longissimis, dense rufo- 

 pubesceutibus, ad apicem nigris, costatis, costis angustioribus. 2 .

Hah. Sumatra {E. C. Buxton., Esq.). 



Forehead evenly convex, black, very finely pubescent, rostrum 

 about three times as broad as long ; maxillary palpi very stout. 

 Antennte three quarters the length of the elytra, compressed ; the 

 third joint about twice as long as broad, emarginate at the apex ; 

 the fourth to ninth joints about equal in length, the lower anterior 

 angle obliquely and much produced, increasingly so as they approach
