14 Phytophaga Malayana. 



botli sexes may be readily distinguished by the nigro-cseruleous 

 tint of the darker portion of the elytra (which varies very little in 

 extent), by the pale upper lip, and by the black markings on the 

 upper surface of the joints of the antennae ; these markings vary 

 very greatly, in some specimens being confined to mere patches 

 near the apex of each joint, in others covering the whole of the 

 upper surface, leaving only a pale line beneath. 



12. Lema alriceps, n. sp. 



Siibelongata, parallela, ful vo-lestacea ; capite (collo praetermisso), 

 abdomine, pedibus posticis (femoribus basi exceptis), tarsis, 

 tibiisque quatuor anticis (his basi plus minusve exceptis) 

 nigris; antennarum articulo ultimo albo ; thorace posterius 

 profunde constricto ; elytris ab apice vix ultra medium 

 obscure nigro-caeruleis, basi elevatis, infra basin profunde 

 transversim sulcatis, subtilissime punctato-striatis, interspatiis 

 ad apicem obsolete convexiusculis. 



Mas. — Femoribus posticis minus valde incrassatis, muticis; tibiis 

 ejusdem paris infra basin ad apicem vix incrassatis. 



Fcem, — Femoribus posticis modice incrassatis, muticis. 



Long. 2^ — 3 lin.

The black head and white apical joints of the antennae, together 

 with the unarmed hinder femora in the S > will separate this 

 from the foregoing species, the larger size and pale thorax from 

 L. Hebe.
