*124. Epipedonota MARGiNEPLiCATA, Ciwr^. 



Nigra nitida, thorace concavo in disco longitudinaliter in tnarginibus transversa 

 striato, elytris porcis 2 exteriore fortiore : intervallo inter hunc niargineni- 

 que exteriorem regulariter transversa canaliculato (Tab. XLI. fig. 16.). 



Length 11 lines, breadth 6. 



Black, shining ; antennae short, with whitish hairs, the extremities silky whitish ; clypeus 

 and head punctured on the sides : thorax very broad, concave, narrowed in front and 

 deeply emarginate, the angles acuminated ; sides very convex, the base bisinuated, tri- 

 gonate and rounded, the centre striated longitudinally and forming irregularly-vermi- 

 culated lines leaving plain spaces, with a very large transverse oval impression, reaching 

 almost to the anterior and to the lateral margins, which are broad and transversely 

 channeled : elytra gradually increasing from the base, which is concave and very broad, 

 to a little beyond the middle, where it is very much sloped off, the apex being tri- 

 gonate ; there are 2 wavy striae on the back, leaving the suture and the space between 

 them a little raised and undulating ; nearer to the external margin is a large ridge, raised 

 most beyond the middle, the space between them with deep transverse channels, form- 

 ing broadish convex spaces, about 18 in number; inflected margin smooth: abdomen 

 striated, excepting the last 2 joints, which are partially punctured. 



December, Port St. Elena, Lieut. Graves. 



The foregoing Nyctelidce formed the finest group brought home by Capt. 

 King and Mr. Darwin; those submitted to my examination amounting to 12 

 species, 8 of which were nondescript ; and probably those captured by the 

 latter gentleman were equal in number and rarity.
