IV. — Descriptions of New Genera and Species of Eumolpidae. 

 By J. S. Baly, 

 The chaotic state of the Eamolpidie, the crowd of species which 

 remain unnamed and unarranged in our collections, and the want of 

 generic landmarks, have induced me to select some of the more 

 interesting for description, proposing in many instances new genera, 

 of which I have briefly given the differential characters. 



Genus Basilepta. 



Caput exsertum, facie subelongata, fere perpendiculare ; oculis prominen- 

 tibus, rotundatis, integris ; antennis gracilibus, filiformibus, corpore lon- 

 gioribus, articulo tertio quarto fere dimidio breviori ; pcdpis maxillaribus 

 subfiliformibus, articulo ultimo angustato-ovato, ad apicem attenuate 

 Tlwrax lateribus marginatis, pone medium angulatis ; antepectoris seg- 

 mento antero-laterali (fig. 1 b) cuneiformi, apice acuto, angulo exteriori 

 ad thoracis angulum anticimi extenso. ScuteUum subtrigonatum, apice 

 obtusum. Elytra thorace latiora, oblonga, modice convexa. Pedes 

 elongati, graciles; femoribus dimidio basali attenuatis, filiformibus, 

 dimidio apicali incrassatis, ampullatis, quatuor posticis subtus ante 

 apicem dente acuto armatis ; tibiis gracilibus, extus ante apicem emar- 

 ginatis ; tarsis (fig. 1 d) gracilibus, articulo primo duobus sequentibus 

 aiquali ; unguicido (fig. 1 c) basi appendiculato. 



Type, Basilepta longipes, Baly. 



Basilepta longipes. (Plate I. fig. 1.) 

 B. subelongata, valde convexa, nitida, supra obscure viridi-senea ; pedibus 

 elytrorumque tuberculo obscure piceis, corpore subtus antennisque (his 

 basi fulva exceptis) nigro-piceis ; thorace lateribus angidato. — Long. 

 2 1in. 



Subelongate, very convex, nitidous, above obscure metallic green, 

 body beneath and the antennae (the fulvous base of these latter excepted) 

 obscure pitchy-black ; a large shining circular protuberance on the 

 basilar space of each elytron, together with the legs, piceous ; attenuated 

 base of four posterior thighs obscure fulvous. Head smooth above, 

 forehead with a longitudinal groove ; lower portion of face deeply 

 punctured ; antenna? slender, filiform, longer than the body, three basal
