middle of the disk, and on the sides; on the hinder disk are 

 several shallow, ill-defined, longitudinal sulcations. 



Genus Mimastra. 



Corpus elongatum, modice convexum, dorse subdepressum. Caput 

 exsertum ; facie subperpendiculare ; antennis corpore brevioribus, 

 gracilibus, filiformibus, articulo prime elongate curvato, a basi ad 

 apicem incrassato, secundo ad tertiam partem primi aequali, tertio 

 secunde duple longiere, quam articulum quartum pauUo breviere, 

 caeteris singulatim quarto fere sequalibus ; palpis maxillaribus lan- 

 ceelato-ovatis, apice acuminatis. Thorax trausversus, lateribus an- 

 guste marginatis, obsolete angulatis ; disco irregulariter excavate. 

 Elytra thorace latiera, postice pauUo dilatata, lateribus anguste ex- 

 planato-marginata, modice convexa, dorse deplanata, confuse punc- 

 tata. Pedes graciles, sat elongati ; coxis anticis erectis, contiguis ; 

 femoribus posticis nen incrassatis ; tibiis omnibus apice muticis ; tar- 

 soriun posticorum articulo basali duobus sequentibus conjunctim 

 sequali; unguicuUs bifidis. Prosternum obsoletum. 



Type, Mimastra arcuata. 



The less exserted and smaller head, the shorter third joint of 

 the antennae, the flattened upper surface, together with the 

 obsolete prosternum, separate the genus before us from Momcea. 



Mimastra arcuata. 



M. elengata, subnitida, dorse subdepressa, subtus obscure olivacea ; 

 capite thoraceque fusco-fulvis,ilIo vertice, hoc disci maculis quinque 

 metallico-elivaceis ; antennis pedibusque piceis, femoribus infra 

 tibiisque apice fulvis ; scutello nitido, nigro ; elytris subelongatis, 

 postice leviter ampliatis, granulosis, obsolete rugulosis, tenuiter 

 punctatis, metallico-elivaceis, singulatim limbo lateral! fasciaque 

 arcuata prope medium posita, ad marginem adfixa, fulvis. 

 Long. 4 1 lin. 

 Hab. India. 



Thorax one-half broader than long ; sides distinctly margined, 

 nearly straight and parallel, moderately dilated, obtusely angled 

 just before their middle; upper surface covered with about six 

 large excavations; the green patches are arranged two in the 

 middle of the disk, and three in front of the basal margin, the 

 two lateral larger than the others. 



Genus Sastra. 

 Corpus elongatum, convexum, supra pube brevissima adpressa 

 plus minusve dense vestitum. Caput exsertum ; facie perpendi- 

 culari, brevi, transversa ; mandibulis mediocribus ; antennis corporis 

 longitudini fere a^qualibus, gracilibus aut sat gracilibus, filiformibus ; 

 articulo prime curvato, a basi ad apicem incrassato, secunde brevi, 

 tertio duobus prsecedentibus lengitudine sequali aut paullo longiere, 

 quarto et sequentibus singulatim tertio brevioribus, inter se fere 

 cequalibus j oculis magnis, prominentibus, integris ; palpis maxillari-
