an tennis nigris, basi pallide piceis ; thorace sat crebre 

 punctato, lateribus rotundatis, angulis posticis late ro- 

 tundatis, fere obsoletis ; elytris sat crebre punctatis. 

 Long. I lin. Hab. — Jamaica. 



Head exserted, subtrigonate ; vertex and front distantly 

 pnnctured, the latter impressed on either side above the 

 encarpa with a deep fovea; encarpse triangular, con- 

 tiguous ; carina raised, linear, elongate ; clypeus rugose 

 on either side the carina, its anterior surface oblique, 

 smooth, impunctate ; antennae nearly three-fourths the 

 length of the body, slightly thickened towards the apex, 

 the five lower joints piceous, the rest black. Thorax 

 about one-fourth broader than long; sides rounded, the 

 hinder angles broadly so, nearly obsolete, the anterior 

 ones thickened, obliquely truncate ; disk rather coarsely 

 punctured, their interspaces irregularly strigose. Elytra 

 much broader than the thorax, narrowly oblong, convex, 

 coarsely punctured. 



Phyllotreta malayana. 



Elongata, parallela, nigra, nitida, pedibus anticis 

 quatuor obscure piceis ; supra obscure nigro-cserulea, sat 

 rude punctata ; antennis nigris, basi piceo-fulvous. 



Long. 1 lin. Hab. — Celebes. 



Head trigonate, rather longer than broad; clypeus 

 obscvire piceous ; vertex shining, impvmctate ; encarpge 

 well defined, triangular, contiguous ; carina raised, its 

 apex acute ; antennee nearly three-fourths the length of 

 the body, robust ; five lower joints obscure fulvous, more 

 or less stained with piceous, the rest black. Thorax 

 nearly twice as broad as long; sides parallel, slightly 

 convex, the anterior angles obliquely truncate, produced 

 laterally into an obtuse tooth ; upper surface coarsely but 

 not deeply punctured, the interspaces granulose. Elytra 

 rather broader than the thorax, their sides parallel ; upper 

 surface more deeply punctured than the thorax, the 

 interspaces shining, impunctate. 



Phyllotreta Downesi. 



Elongata, convexa, viridi-metallica, cyaneo tincta, an- 

 tennis nigris; subtus nigra, femoribus posticis viridi- 

 metallicis; thorace granuloso, sat fortiter punctato;
