Mr. J. S. Baly on the Phytophnga. 203 



The insects composing the gomis Leptarthra have hitherto been 

 placed in Coshmera ; the resemblance, however, is only external, the 

 structure of their antennae, together with all their other characters, 

 differing so completely as to render it unnecessary to point out the 

 distinctive marks here. 



Leptarthra ahdominalis. 



L. ovata, postice pauUo ampliata, convexa, nitida, obscure viridi-metallica, 

 pui-pureo-micans ; abdomine eljiirisque rufo-testaceis, bis fortiter sub- 

 crebre punctatis, antennis scutelloque nigris, — Long. 41-5^ lin. 



Hab. Northern India. 



Antennae slender, equal in length to the body ; thorax one-half 

 broader than long, sides nearly straight and parallel, narrowed in fi'out, 

 anterior angles prominent, their apex obtuse, upper surface smooth and 

 shining, grooved transversely just behind the anterior border, the 

 hinder disk impressed with thi-ee large deep circular fovete arranged 

 transversely in a gentle curve ; scuteUum semiovate ; elytra deeply 

 punctured, the disk of each with two or more nearly obsolete longi- 

 tudinal vittcie ; anal segment of abdomen in the male impressed by a 

 shallow fovea. 



Leptarthra Dohrnii. 



L. oblonga, postice paidlo ampliata, convexa, nitida, obscm-e viridi-me- 

 tallica ; elytris subfortiter striato-punctatis, striis prope suturam et ad 

 latera saepe confusis, punctis in striis inordinatini dispositis. — Long. 

 3-7 lin. 



Hab. Northern India. 



Antennae slender, equal in length to the body ; thorax at the base 

 nearly twice broader than long, sides nearly straight, narrowed from 

 their base to the apex, the anterior angles prominent, their apex sub- 

 acute, upper surface sculptm-ed nearly as in the preceding species, the 

 transverse groove in front more deeply impressed, strongly sinuate in the 

 middle, and sending a short longitudinal groove backwards to the cen- 

 tral fovea ; scuteUum rather narrower than in Leptarth-a abduminalis ; 

 surface of the elj-tra punctate-striate, each stria being fomied of several 

 iiTegular rows of punctures, the outer strife and those near the sutm-e 

 more confused and often quite lost, interspaces impressed with scattered 

 punctm'es which vary both in number and depth, sometimes being as 

 deep as those forming the striae themselves ; on the suture, a short 

 distance below the scuteUum, is a broad shallow depression ; anal seg- 

 ment of abdomen in the male impressed by a deep semiovate fovea. 



Genus Palpoxena. 



Corpus subelongatum. Caput exsertum ; antennis gracUibus, filifonnibus, 

 corporis longitudine, articulo prime a basi ad apicem breviter incrassato, 

 secimdo brevissimo, tertio primo pauUo longiorc ; labro transverse ;
