Phytophagous Coleoptera. 461 



Genus parastetha, Baly, n. geu. 



Corpus late oblongum, convexum. Caput exsertum, ocidis 

 magnis, rotundato-ovatis, prommentibus, integris; encarpis traus- 

 versis, contiguis ; antennis quam corpora multo brevioribus, 

 robustis, articulo primo subclavato, secuudo et tertio brevioribus, 

 cylindricis, casteris compressis, modice dilatatis. Thorax traus- 

 versus. Elytra thorace longiora, confuse striatim punctata. 

 Pedes modice robusti, coxis anticis conicis, pauUo compressis; 

 femoribus simplicibus; tibiis posticis quatuor apice spina acuta 

 armatis ; nngiiiculis appendiculatis. Prosternwn angustum, 

 inter coxas distinctum, apice abrupte dilatatum ; acetabnlis 

 anticis apertis. Mesosternum occultum. Metastermmi in spi- 

 num validum inter coxas intermedias productuni. Type P. 

 nigricoimis. 



This genus must stand very close to Hylaspes, it is chiefly 

 separated from that genus by its much shorter antenna^, which 

 scarcely exceed half the body in length. 



1. Parastetha nigricornis, n. sp.

 oculis antennisque (articulis basalibus tribus exceptis) nigris,

 verso, utrinque leviter sed late foveolato ; elytris distincte,

Hab. Assam. 



Head trigonate; vertex sparingly punctured; encarpa^ trans- 

 verse, arcuate, contiguous ; labrum deeply notched ; antennae 

 less than two-thirds the length of the body, robust, the basal 

 joint clavate, the second and third short, equal, obconic, the 

 fourth and following ones compressed, moderately dilated, the 

 fourth (which is nearly equal in length to the preceding three 

 united) to the tenth elongate-trigonate, the eleventh ovate. 

 Thorax nearly three times as broad as long ; sides nearly parallel, 

 slightly rounded, the posterior and anterior angles thickened, 

 the latter produced, very obtuse ; disc sparingly punctured, 

 impressed on either side towards the lateral margin with a large 

 ill-defined shallow fovea, hinder portion of middle disc flattened. 

 Scutellum elongate-trigonate, its apex obtuse. Elytra much 

 broader than the thorax, parallel, rounded at the apex ; above 

 convex, not depressed below the basilar space, distinctly punc- 

 tured, the punctures indistinctly arranged on each elytron in
