and Species of Longicorn Coleoptera. 21 



Cerambyx demissus. 



C. sub-angustatus, fusciis, griseo-pilosus ; prothorace mutico, 

 pHcato ; elytris apice sub-truncatis. 



India (Benares), 



Rather narrow, dark browu, sparingly covered with greyish 

 hairs, which are longer and slightly curved on the elytra, parti- 

 cularly the basal portion ; prothorax unarmed, sub-transversely 

 plicate ; elytra somewhat truncate at the apex ; antennae mode- 

 rate. 



■Length 6 lines. 



Nearly allied to C. egenus, but the ihorax is proportionably 

 longer, more regularly plicate, elytra shorter, &c. 



Hesthesis mcerens. 



H. niger ; prothorace marglne antico elytrisque macula apicali 

 stramineis, his testaceo-olivaceis ; abdomine supra segmento 

 primo tertioque flavo-marginata ; femoribus ferrugineis. 



Sydney. 



Black, space between the eyes, anterior border of the prothorax, 

 and small spot at the apex of each elytra, dull straw colour, the 

 latter testacous olive, darker exteriorly ; abdomen with a band 

 across the first segment, and margin of the third above, bright 

 yellow beneath, the first segment covered with a white silky 

 pubescence ; thighs ferruginous. 



Length 8 lines. 



I have not seen Mr. Newman's H. hizonatus ; his description is 

 too short to be of any use, but it ditFers from this species in the 

 ferruginous base of its antenna^. 



OXYLYMMA. 



Head prolonged into a snout; eyes round, prominent, nearly 

 entire, distant below ; antennae short, filiform, the fourth joint as 

 long as the fifth, the third twice their length, the rest shorter ; 

 prothorax smooth, narrower in front ; elytra short, depressed, 

 each gradually narrowing to a point ; femora stout, clavate ; tibiaj 

 lengthened ; tarsi short, the first joint of the posterior not greatly 

 exceeding the second in length. 



The affinity of this genus is with certain small insects confined 

 apparently to the Valley of the Amazons, which Mr. White has 

 placed in Rhinotragus,aiid to which he also refers Oregostoma. It
