We have received specimens of all the forms (except 5) of this variable species from 
Cuernavaca, not only from M. Sallé but also from Herr Hoge. S. nigripennis is dis- 
tinguished from the allied species by its narrow and very elongate shape, shining hairy 
surface, black or piceous head, reddish thorax, and (in the typical form) bluish-black 
or nigro-gneous elytra. The head is comparatively narrow (and owing to the long and 
prominent labrum appears very elongate), and has a few coarse setiferous punctures 
between the eyes and at the base ; the eyes are rather small and oblique ; and the antenne 
are rather long, and have the apical joint in the male longer, in the female shorter, 
than joints 8-10 united. The thorax is convex, rather longer than broad, immarginate 
laterally, and has (except on the middle of the disc) a few scattered coarse punctures. 
The elytra are long, and finely and rather deeply punctate-striate ; the interstices are 
flat at the base but become convex towards the apex, and each has an irregular row of 
rather closely placed setiferous impressions extending from the base to the apex. The 
femora and tibie on all sides are clothed with long scattered erect hairs. 
In the Sallé collection S. nigripennis is separated into five species, though all are 
from the same locality and differ in nothing except colour. S&S. nigripennis varies from 
7-9 millim. in length and from 12-24 millim. in breadth. 
59. Statira nigrosnea. (Tab. II. fig. 19, 3, var.) 
Elongate, narrow, nigro-sneous, shining, the surface clothed with moderately long erect hairs. Head with 
scattered very coarse punctures, the eyes moderately large; antenne not very stout, piceous, the apical 
joint in the male longer, in the female less, than joints 8-10 united; prothorax convex, about as long as 
broad, the sides immarginate (or obsoletely margined at the extreme base), rounded anteriorly, and 
moderately constricted behind, the hind angles not very prominent, the basal margin very little raised, 
the disc sometimes a little depressed in the middle before the base, the surface with very coarse widely
