354 Mr. F. P. Pascoe on some new or little-hnown 



uniformly coloured species represented by lolea prolata, longicornis, 

 and others ; and at the same time it is so evidently allied to Seriooia, 

 that I do not see any characters by which they can be kept apart. 

 Seriocia, as the oldest name, must therefore be adopted. Tn addition 

 to the characters previously given (Trans. Ent. Soc. 2 ser. iv. p. 45), 

 the genus may also be recognized by the little narrow lobe on the 

 disk of the prothorax posteriorly, but which never attains to its 

 margin. 



Serixia cephalotes. 



S. rufo-testacea ; elytris, basi excepta, infuscatis^ griseo pubescentibus. 



JIab. Batchian. 



Moderately narrow, pale reddish testaceous ; head and prothorax ob- 

 soletely punctured, finely pubescent ; scutellum small, triangular ; elytra 

 remotely seriate-punctate, very dark ashy, and, from the varying light 

 of the somewhat silky pubescence, much paler in certain positions, 

 especially towards the apex j antennae two or three times as long as the 

 body, brownish, base of the first and foiu-th joints testaceous ; legs and 

 body beneath pale testaceous ; eyes and mandibles black. Leng-th 3^-4 

 lines. 



In one of my specimens the breadth of the head is nearly twice 

 that of the prothorax ; in two others it is considerably less, although 

 still exceeding the ordinary size ; the antennae, also, are of variable 

 length. 



• Serixia sedata. 



S. rufo-testacea, sat lata ; elytris grisescente pubescentibus, apice aliquando 

 infuscatis ; oculis, antennis, mandibulisque nigris. 



Hab. Siam. 



Reddish testaceous, inclining to ferruginous, with a thin greyish 

 pubescence ; head and prothorax with shallow scattered punctm^es, the 

 latter transverse and narrower than the former; scutellum broadly 

 triangular ; elytra seriate-punctate, the apex in some individuals black, 

 more or less brown or entirely concolorous in others ; eyes and mandi- 

 bles black; antennae gTe5dsh brown, pubescent, half as long again as 

 the body, rather stout, the fourth joint with the basal half, and occa- 

 sionally the bases of the sixth and eighth also, reddish ferruginous. 

 Length 3^ lines. 



The rings on the antennae are in some examples scarcely apparent. 



EiJMATHES [Lamiidae]. 

 (Dejean, Cat. de Coleop.) 



Head short, nai-rower below the eyes. AntenuiB setaceous, longer than 

 the body, distant at the base, the first joint of moderate length and 

 thickness, the third longest of all, the remainder gi'adually decreasing
