34 Mr. J. S. Baly on new Genera and Species of Phytophaga. 



groove; vertex bright metallic green; antennae short, subiili- 

 form. Thorax nearly three times as broad as long, sides rounded, 

 nearly straight and parallel at their base, converging towards 

 the apex, anterior margin nearly truncate ; upper surface smooth 

 and very remotely punctured on the disk, more deeply and 

 closely punctured on the sides. Elytra irregularly punctate- 

 striate, the punctui*es deeply impressed and arranged in irregular 

 double longitudinal rows ; beyond the middle these rows become 

 more confused, and the punctures less deeply impressed ; general 

 surface of elytra subremotely covered with irregular transverse 

 grooved lines. The green colour of the under surface varies 

 greatly in extent in different individuals. 



Genus Australica, Chevr. 

 Australica Digglesii. 



A. subelongata, convexa, nigra, nitida ; capite, tborace elytrisque 

 rufo-fulvis, ore, antennis (basi excepta) verticis plagis tribus, 

 thoracis plaga magna discoidali a basi fere ad apicem extensa, 

 scutello elytrorumque singulatim plagis duabus (prima infra 

 basin posita, transversa, utrinque abbreviata, secunda infra me- 

 dium, subrotundata) nigris. 



Long. 3f lin.

Head short, irregularly punctured; front impressed with a 

 longitudinal groove, which extends upwards from the epistome ; 

 on either side, extending backwards from the upper border of 

 the eye, is a large black patch, a third (smaller and subtrigonate) 

 being placed on the middle of the vertex : antennae slender, 

 slightly thickened towards their apex ; four basal joints fulvous, 

 stained with piceous above, the others black. Thorax twice as 

 broad as long, sides parallel, slightly converging in front ; sur- 

 face irregularly, but not closely, punctured. Elytra each with 

 eleven regular rows of distinctly impressed punctures, the first 

 being short. 



Genus Lamprolina, Baly. 



Lamprolina discoidalis. 



L. elongata, convexa, violaceo-senea, nitida ; antennis nigris, basi 

 cyaneis ; femoribus, abdominis limbo, capite thoraceque fulvis, 

 illo fronte, hoc disco, f usco-seneo maculatis ; elytris cupreis, vio- 

 laceo micantibus. 



Long. 3-3| lin.

Face with a large triangular depression, which occupies nearly 

 the whole space between the insertion of the antenna?, and ex-
