982 <- Mr, F. P. Pascoe’s List of the Longicornia 
spatium includente, Jateribus rngoso-punctatis et verrucosis, 
apicem versus subito depressis; antennis, basi excepta, 
omnino.pallidis. 
Dark reddish-brown, with thin scaly pubescence ; head with a 
white spot behind each eye; antennze very slender, about five 
times as long as the body, very pale-yellowish, darker at the 
base; prothorax strongly bituberculate, the sides behind the 
lateral tooth greyish; scutellum semi-circular; elytra very irre- 
gular, raised at the base, a narrow tuberculate crest on each side, 
two warty lines beginning a little before the middle and passing 
backwards to the apex, inclosing a comparatively smooth space 
between them, posteriorly the elytra are rather suddenly de- 
pressed towards the apex, the sides from the shoulders roughly 
punctured and furnished with several prominent warty tubercles; 
body beneath reddish-chesnut ; legs brownish, varied, especially 
the femora, with darker. 
Length 5 lines. 
Nearly allied to 4. asperulus, White, but more uniformly 
coloured, the tubercles at the sides slender and prominent, and the 
spaces between the lines of tubercles on the dise more excavated. 
This member of the group is also found at Rio. 
Onycnocerus scorpio, Oliv. 
ALPHUS*® ASELLUS, N. Sp. 
A. fuscus, pube grisea albido-varia tectus ; prothorace trans- 
verso, disco sige eet utrinque taberculates elytris apicem 
versus attenuato-rotundatis. 
Dark brown, covered with a dense grey pile, varied on the elytra 
with whitish ; head with a broad elevated line on the vertex ;_ pro- 
thorax transverse, disk nearly regular, with a few course punctures 
at the base, and a short broad tubercle on each side; scutellum 
triangular ; elytra gradually tapering from the base to the apex, 
the approach to the latter, therefore, gradually attenuated, not 
suddenly rounded ; body beneath, legs and antenne with a short, 
slightly silky pubescence. 
Length 6 lines. 
An obscure species as regards colour, but distinguished by the 
regular prothorax and tapering elytra. I owe the determination 
of the genera of this and of the next species to Mr. Bates.
