yellow patches, one on each side of the former, and on the latter 

 one very large at the base, and another nearly as large and some- 

 what oblique rather below the middle, and in each case uniting at 

 the suture with its fellow, between these a smaller spot, and 

 another, crescent-shaped, near the apex ; body beneath, and legs 

 testaceous ; a black lunar mark on each side of the metathorax ; 

 antennae fulvous, with the two first and tips of the other joints 

 black.

Differs in coloration from all others in this genus. 



Astathes externa. 



A. flava, nitida ; elytris vix carinatis, subtilissime punctatis, 

 plaga exteriori sub-humerali, violacea ; metathorace macula 

 magna laterali, nigricante. 



India. 



Pale yellow, head and prothorax darker ; elytra with a very 

 faint trace of two carinee very minutely punctured, and towards 

 the shoulder externally a large rich violet patch ; antennae darker 

 at the apex ; metathorax with a blackish spot on each side ;

Aslathes decipiens. 



A. flava, nitida ; elytris quadricarinatis vix punctatis, dimidio 

 basaii violaceis ; metathorace lateribus oculisque nigris, his, 

 parte inferiori, rotundatis. 



Sumatra. 



Pale yellow, inclining to orange on the head and prothorax ; 

 elytra with short stiff hairs, scarcely punctate, except at tlie base, 

 with four raised lines, the two nearest the suture strongly marked, 

 the basal half rich violet; side of the metathorax with a hlackish 

 patch ; antennae with the four last joints, mandibles, and eyes 

 black, the latter having the inferior portion round. 



Length 6 lines. 



Closely allied to A. splendida, F., but rather broader, the elytra 

 almost free from punctures, except at the base, the hairs coarser, 

 the raised lines more strongly developed, and the lower portion of 

 the eye almost perfectly round ; in A. splendida, too, the antennae 

 are darker to a much greater extent.
