CEdionychis Gerrnari. 



(E. late ovata, convexa, nigra, nitida, facie inter oculos, macula 

 utrinque antennisque basi piceo-fnlvis ; thorace albido, fascia 

 pone apicem, utrinque abbreviata, nigra ; elytris distincte, sub- 

 fortiter, punctatis limbo exteriore, fascia mediana nee non sutura 

 inter fasciam et apicem albidis.

Head short ; vertex and front sliining, impunctate ; encarpa3 

 transverse-quadrate, bounded above by a deep transverse de- 

 pression ; carina thickened, narrowly wedge-shaped, termina- 

 ting anteriorly on a strongly raised transverse ridge ; antennas 

 filiform, three lower joints piceo-fulvous, the rest black, third 

 nearly twice as long as the second, scarcely more than half the 

 length of the fourth. Thorax nearly three times as broad as 

 long ; sides broadly margined, rounded and converging from 

 base to apex, the anterior angles produced, mucronate ; disk 

 minutely punctured, lateral margin reflexed, concave. Scutel- 

 lum trigonate, its apex rounded. Elytra broader than the 

 thorax, moderately convex, the lateral margin rather broadly 

 dilated ; surface distinctly and rather deeply but not coarsely 

 punctured, the interspaces between the punctures minutely 

 punctured. Tarsi nigro-piceoiis ; basal joints of hinder tarsus 

 equal in length to the second; claw-joint strongly dilated. 



The broadly oval form will at once distinguish this insect 

 from any similarly coloured species. 



CEdionychis spilota. 



(E. elongato-ovata, modice convexa, nitida, subtus nigra, prothorace 

 pedibusque flavis, femoribus tibiisque apice tarsisque nigris ; 

 supra flava, vertice antennisque (his basi exceptis) nigris ; thorace 

 lateribus late explanatis, rotundatis, disco Isevi, iascia basali, 

 utrinque abbreviata, nigra ; scutello nigi o ; elytris minute, crebre 

 punctatis, utrinque maculis quatuor nigris, duabus infra basin 

 transversim positis, prima elongata super calhim humerale, se- 

 cunda inter callum et suturam, subovata, tertia prope medium, 

 magna, transverso-quadrata, quartaque trigonata ante apicem 

 positis.

Hob. Rio Janeiro. Collected by the late Mr. Squire. 



Head trigonate ; encarpse subquadrate, contiguous, bounded

 labrum, jaws, and cheeks nigro-piceous ; eyes black ; antennae

 joints fulvous, the rest black. Thorax twice as broad as long ;
