624 Mr. J. S. Baly's Descriptions of Phytopliaga. 



Genus Aplosonyx, Chevr. 

 1 . A])losonyx elongata. 



Elongata, parallela, convexa, fiilva, nitida; tibiis extrorsum, 

 tarsis, antennarumque articulis intermediis, nigris ; elytris viri- 

 di-caeruleis, tenuiter piinctato-striatis, punctis in striis con- 

 fuse bifariam dispositis. 



Long. 6 — 9 lin. 



Hab. Northern India. 



Elongate, parallel, convex, shining fulvous. Head prominent, 

 face oblong, forehead impressed with a crucial line ; antennae 

 more than two-thirds the length of the body, tapering towards 

 their extremity, four basal joints fulvous, glabrous, last three ob- 

 scure fusco-fulvous, the rest black; apex of jaws black. Thorax 

 nearly twice as broad as long, sides deeply sinuate, rotundate- 

 dilatate in front, upper surface deeply excavated across the mid- 

 dle, furnished in front with four obtuse tubercles, placed trans- 

 versely at some distance behind the apical margin, the two inter- 

 mediate less distinct and united by a transverse ridge ; surface 

 nearly impunctate, with the exception of five deep punctures 

 placed in a group on either side the centre of the transverse 

 groove. Scutellum elongate-trigonate, obtuse. Elytra metallic 

 greenish-blue, oblong-elongate, sides parallel, apex rounded, 

 shoulders prominent and elevated into an oblique ridge ; on the 

 inner side of the latter is a deeply-grooved line, which, in con- 

 junction with the usual transverse depression below the basilar 

 space, and a faint longitudinal groove on the inner edge of the 

 suture, bounds on each elytron a slightly elevated oval space ; each 

 elytron with ten finely punctured striae, each stria formed by a 

 double row of punctures, more or less regularly placed along 

 the line ; at the base, near the scutellum, and also on the middle 

 of the hinder disc, the puncturing is much more confused and the 

 striae are nearly lost. 



The different punctation of the elytra, together with the tu- 

 berculate thorax, separate this insect from all other concolorous 

 species of the genus.
