Genus Aspidispa. 



Corpus sub-ovatum, postice paullo subdepressum. Caput 

 obtusum, inter antennas in cretam elevatam antrorsum 

 productum ; antennis filiformibus, corporis dimidio longi- 

 tudine fere gequalibus, ad apicem vix attenuatis, articulo 

 primo incrassato, ob-ovato^ secundo ovato, prime vix 

 breviorij tertio paullo elongate; mandihulis apice obtusis ; 

 ojiento oblongo; liguld segmento basali integro. Thorax 

 transversus. Elytra thorace multo latiora, subcordata, 

 lateribus basi rotundato-ampliatis, bine apicem versus 

 oblique angustatis, apice conjunctim rotundatis ; dorso 

 subdepressa^ hie illic profunde excavata ; utraque bicostata, 

 costis valde interruptis^ interspatiis profunde biseriatim 

 punctatis, interstitiis transversim costatis. Pedes breves, 

 antici (^ valde incrassati ; tihiis anticis trigonatis ; tarsis 

 quatuor anticis latis, anticis (^ transversim ampliatis; 

 unguihus articulo penultimo sequilongis, illo fere occultis. 



This very singular form resembles closely the genus 

 Hoplionota, and at first I had considerable doubt whether 

 it really belonged to the present family; but M. Boheman, 

 to whom I showed it, at once pronounced it to be one 

 of the group of Hispidw. It must stand close to Go- 

 iiophora. 



The mentum differs in form in the two sexes ; in the ^ 

 its anterior surface is deeply concave ; in the ? it is plane 

 and raised towards the apex into a longitudinal ridge. 



Aspidispa tibialis. 



Sub-ovata, subdepressa, fulva, nitida, supra (facie an- 

 tennisque exceptis) nigro-cserulea, vertice utrinque, tho- 

 racis lateribus vitta submarginali, scutelloque rufo-piceis ; 

 thorace transverse, hie illic rude punctate, basi arcuatim 

 sulcato, lateribus obtuse rotundatis, minute serratis; 

 elytris subcordatis, thorace multo latioribus, basi rotun- 

 dato-ampliatis, hinc apicem versus rotundato-angustatis, 

 apice conjunctim rotundatis, dorso hie illic late et pro- 

 funde excavatis, utrisque tricostatis, costis interruptis, 

 interspatiis profunde biseriatim punctatis, interstitiis hie 

 illic transversim elevatis.
