verse, the fifth to tenth forming an elongate club. Hyes 
rather large, somewhat approximate below. Thorax trans- 
verse. Elytra elongate, parallel, rounded at the apex. Ante- 
rior coxe large, conical; anterior tibiew short, wide at the 
apex, with two very strong teeth on the outer edge; tarsi 
nearly as long as the tibia; claws short, with a very strong 
tooth towards the apex. Intermediate tarsi long and slender, 
about one third longer than the tibia; the claws to these and the 
posteriortarsi very slightly curved, flexuous, with an obtuse tooth 
at the base, an acute tooth (made by a fissur e) towards the apex ; 
the apex very acute, curved. Posterior tarsi nearly 34 times 
as long as the tibia, very slender ; the basal joint the longest ; 
all clothed with very long delicate hairs. Metasternum rather 
long. Pygidium acuminate. 
I place this genus next to Pachycolus, but with some 
doubt. 
Trichinopus flavipennis, sp. nov. 
T. elongatus, parallelus, nitidus, hirsutus, pallide piceus, elytris 
tlavo-testaceis ; capite piceo-nigro, fronte discrete punctulata, 
planata ; clypeo concavo, piceo, discrete punctulato, antice medio 
leviter emar pinate, angulis rotundatis ; thorace fere duplo latiore, 
longitudine + latiore, piceo, antice leviter emarginato, angulis 
anticis obtusis, lateribus rotundatis, angulis posticis omnino ro- 
tundatis, basi vix arcuata, disco utrinque diserete punctulato ; 
scutello elongato-triangulari, piceo; elytris thorace vix latioribus, 
fere triplo longioribus, leviter convexis, flavo-testaceis, parallelis, 
ad apicem conjuncto- -rotundatis, irregulariter sat crebre distincte 
punctatis ; tibiis anticis Beonibue! extus fortiter bidentatis, tarsis 
brevibus ; tarsis intermediis longis; tarsis posticis longissimis, 
tibia fere 33 longioribus, gracilibus, pilis pallidis prelongis 
ornatis. Long. 4 ee lat. 14 lin. 
The whole upperside of this insect is clothed with pale 
pubescence, which is very long on the thorax and sides of the 
elytra. The underside of the body and the legs are mode- 
rately covered with long hair; the intermediate tarsi have 
only a few hairs at the apex of each joint ; the posterior tarsi 
are remarkable for the very long pale delicate hair with which 
they are thickly clothed.
