and Species of Asiatic Longicorn Coleoptera. 45 



At the first glance this species closely resembles the West 

 African A. testator, F., from which, however, it is abundantly 

 distinguished by the apical spine and well marked characters in 

 the elytra and antennge. 



Serixia. 



Head wider than the thorax, the antennae filiform, longer than 

 the body, with the first, third and fourth joints sub-equal and 

 slightly spined at the end, the under surface ciliated ; thorax 

 short, equal, with the anterior and posterior margins grooved ; 

 elytra depressed, dilated posteriorly. 



This genus has much the form of Astathes and Entelopes, but 

 diflPers from both in its longer and more slender antennae. 



Serixia apicalis. (PI. XVI. fig. 3.) 

 S. griseo-glauca, nitida ; elytris sericeo-tomentosis, striato- 

 punctatis, apice luteis ; thorace, capite, antennisque nigris ; 

 pedibus flavis. Malacca. 

 Glaucous grey, the elytra silky shining, striate punctate, with a 

 bright luteous spot on the apex of each ; antennas and eyes 

 black ; the head and thorax black, with a slight tinge of grey ; legs 

 yellow. 



Length 5 lines. 



Serixia modesta. 



S. griseo-nitida ; elytris sericeo-tomentosis punctato-striatis ; 



thorace capiteque obscure fulvis ; antennis nigris ; pedibus 



flavis. Borneo. 



Smaller than the last, and without the apical spot ; the head 



and prothorax of a dull fulvous colour, in other respects very 



similar. 



Length 4 lines. 



Neoxantha. 

 Head small ; eyes reniform, undivided ; antennae moderate ; 

 maxillary palpi clavate ; prothorax rounded, equal ; elytra 

 convex ; legs robust. 



A genus near Astathes, but differs in its reniform undivided 

 eyes, clavate palpi and other characters. 



Neoxantha amieta. (PI. XVL fig. 4.) 

 N. croceo-flava, pilosa ; prothorace tuberculis trlbus nigro- 



nitidis ; elytris singulis plagis duabus viridi-nigris ; antennis 



variegatis, tarsis nigris. China Borealis. 

 Light saffron yellow, densely hairy, with longer setose hairs
