Longicornia Malayana. 237 



The type of this genus was referred by Mr. White to Cereopsius, 

 but the large head and smaller eyes, together with the form of the 

 prothorax, strongly constricted at the apex and base, and the 

 nearly central position of the spine, are at variance with the 

 characters laid down for that genus. The figure of this handsome 

 insect given by Mr. White does it very scant justice.

 a few scattered punctures, deeply impressed with an irregular 

 transverse line before the spine and another behind it, the centre of 

 the disk irregularly corrugated ; scutellum broadly triangular, its 

 apex slightly rounded ; elytra with a few large ])unctures at the 

 base, the black portion of the basal spot enveloping the shoulder 

 and nearly extending to the suture ; body beneath dark chesnut, 

 shining, pubescent at the sides ; legs paler, passing into luteous 

 at the tarsi ; antennae brown, thinly pubescent.
