Capt. P, P. King's South American Coleoptera. 465 



nulated : legs stout, sometimes ferruginous ; anterior tibiae crenulated, with a small 

 external apical spine, the others scabrose : inflected margin striated obliquely ; pectoral 

 lobe large and rounded, coarsely punctured, with an elongated horseshoe channel ; pec- 

 tus rugose, centre of abdomen somewhat vermiculate. 



This fine species was not uncommon at Cape Fairweattier. From its beau- 

 tifully sculptured surface, shining like ebony, I had named it N. sculpturata, 

 but I am happy in adopting the name of the distinguished naturalist which 

 has been lately assigned to it by Mr. Waterhouse. 



*119. Nyctelia? corrugata, Curt. 



Nitidfe nigra, thoracis lateribus rugosis, elytris transversim undulato-canali- 

 culatis porcas plurimas undulatas formantibus : sutura depressa bistriatS. 

 (Tab. XLI. fig. 14.). 



Length Q^ lines, breadth 5. 



Black, smooth and shining : antennae brown ; clypeus emarginate, with a transverse groove, 

 sides slightly punctured ; head with a long puncture on the crown : thorax twice as 

 broad as the head, a little broader than long, scarcely narrowed before, but very con- 

 cave, forming acute angles, sides very convex, contracted at the base, the angles ovate, 

 the base straight and slightly striated longitudinally, lateral margins thickened and gra- 

 nulated internally, with numerous oblique furrows, inclining towards the head and form- 

 ing short ridges ; scutel minute and broad : elytra oval, convex, broader than the thorax 

 at the base, but not twice as broad at the middle ; suture very much depressed, with a 

 groove on each side, the outer margin keeled and crimped, the entire back with nume- 

 rous deep transverse grooves, somewhat oblique at the base and apex, forming convex 

 ridges ; each elytron with 2 indistinct curved longitudinal striae, apex rather pointed and 

 margined ; inflected margin scratched only : pectoral lobe clavate, with a deep channel 

 round : legs stout, hinder the longest ; anterior tibiae without an external spine at the 

 apex, granulated outside, as are all the others, the hinder being crooked ; basal joint of 

 tarsi but slightly elongated. 



This distinct species, which was not uncommon at Cape Fairweather in 

 December, seems to connect Nyctelia with Epipedonota, for the anterior tibiae 

 are longer than the tarsi, and the external spine is wanting at the apex ; yet 

 the habit of the insect and the trophi apparently accord so strikingly with 

 Nyctelia, that unless it be made a distinct genus, I think it better to let it 

 form a section of that group.
