The spines at the apex of the posterior tibize are longer than usual 
in the genus.

This species was first discovered by Capt. King, and will be here- 
after described in detail by Mr. Curtis, whose MS. name I have 
adopted. Two specimens were found by Mr. Darwin at Port Desire : 
it approaches very near in size and general characters to N. Darwinii, 
but differs in having red legs and antenne, in being of a broader 
form, in having the legs less rough, the lateral keel of the elytra less 
prominent, and not so distinctly crenulated, and the spurs or spines 
at the apex of the posterior tibiz are much smaller. The length of 
the elytra is rather less than the width, if the produced apical portion 
be omitted; and if included in the measurement, the length very 
slightly exceeds the width; they are very convex and smooth, and 
so is the thorax, which is twice as broad as long, and considerably 
narrower before than behind. ‘The head is sparingly punctured. 
Nycreta GranuLata, Curtis, MSS. Nyct. atra, nitida, subro- 
tundata ; capite transversim impresso, anticé punctato ; thorace sub- 
quadrato, ad latera crenulato, supra convexo, levi; elytris rotun- 
datis, apice pauld productis, supra convexis, ad suturam depressis, 
rugis validis et irregularibus obsitis, his in dorso plerumque lon- 
gitudinalibus et prope latera oblique dispositis.

Hab. Cape Negro. 
This, together with several nearly allied and very remarkable spe- 
cies of Nyctelia, occurs in Capt. King’s collection, and will be here- 
after characterized in detail by Mr. Curtis. The specimen from 
which the above short description is taken forms part of Mr. Darwin’s 
collection, and was found at Cape Negro. The legs are very rough, 
being thickly covered with tubercles, and they are shorter than in 
most of the species of Nyctelia. The whole upper surface of the 
elytra is covered with rugz, and these are very strongly marked, and 
though very irregular, they have a general longitudinal direction on 
the depressed space on the middle of the elytra. This sutural de- 
pression, which is about two lines in width, is bounded on each side 
by a broad and slightly elevated ridge; between this ridge and the 
outer margin the rugz have a tendency to form oblique lines. A 
few fine punctures are observable on the fore-part of the thorax, and 
on the sides are two grooves placed closely together, and parallel
