352 Longicornia Malayana. 



the scape pitchy ; prothorax with the gibbosity sh'ghtly ridged on 

 each side, each ridge deeply excavated anteriorly; elytra narrower 

 than in the preceding, punctures small. 



Length G| lines. 



This is a flatter insect than A. poslicaUs, which it much re- 

 sembles in colour, but is narrower, with the disk of the prothorax 

 slightly keeled on each side of the gibbosity. Astatlies ignoranti- 

 nus, J. Thorns. (Arch. Ent. i. 51), differs in the body being yel- 

 low beneath. 



A statlics Jlavivenlris. 

 A.($) angustata ; capite prothoraceque nigris ; elytris viola- 

 ceis, parte apicali flavis ; pectore, fenioribus tibiisque piceis ; 

 abdomine flavo. 

 Hab. — Sarawak. 



Much narrower than either of the preceding, and scarcely dif- 

 fering in coloration from the last, except that the abdomen is 

 bright yellow ; prothorax without any point, the gibbosity simply 

 rounded above and sinking on each side posteriorly; elytra finely 

 punctured ; scape and second joint of the antennse pale chesnut, 

 the last three or four joints black. 

 Length 5 — 6 lines. 



The male is unusually narrow ; the violet is sometimes re- 

 placed by purple. 



Astatkes content losn. 



A. capite prothoraceque nigris ; elytris purpureis, parte api- 

 cali flavis ; corpore infra femoribusque purpureo-nigris, 

 nitidis ; disco prothoracis in medio oblongo-tuberculato. 



Hab. — Singapore. 



Head and prothorax black ; basal half of the elytra purple, the 

 remainder yellow, the two colours limited in an oblique direction 

 from the middle of the suture outwards ; body beneath and fe- 

 mora glossy purplish-black ; antenncE, tibiie and tarsi yellowish, 

 the former pitchy at the base and brownish at the apex ; prothorax 

 only slightly elevated on the disk, the middle with an oblong 

 tubercle strongly punctured on each side. 



Length 5 lines. 



I have only seen a single example of this species, which agrees 

 pretty much in colour with A. terminafn, but is at once distin- 

 guished by its prothorax.
