along the tarsal groove; the posterior tarsi (the only ones I have 
been able to examine) are less slender than in the following 
species, with the 1st joint a little longer than the 2nd, which is 
about equal to the 3rd, and not shorter, as in the subgenus T'@enio- 
cerus. Schaufuss is in error in stating that the 1st joint is twice 
as long as the 2nd, and that the antennal funiculus is 4-jointed. 
It is exceedingly short, and the joints are almost impossible to 
count unless it is mounted in balsam. I have made out certainly 
five, and I believe six, the number in all the other species. ‘The 
club is not acuminate ; and Herr Schaufuss informs me that there 
is no marked difference in the male antenne.

Pars basilaris capitis in utroque sexu margine concavo; mentum 
pedunculo triangulari insertum, in feminis ter longius quam latius. 
Prothorax angulis posticis productis, basi valde bisinuata, in medio 
producta. Tarsi longi, tibiis fere adzquantes, articulis angustis ; 
articulo 3io 2do duplo fere longiore. 
Mas. Antennis dimidio corporis longioribus, scapo elongato, 
recto, clavato, funiculo flexili, articulis duobus primis elongatis, 
ceteris transversis, clava longissima, valde acuminata, apice piloso. 
Fem. Antennis brevibus, funiculo recto, articulo lmo capitato, 
2—6 transversis, latitudine vix crescentibus, clava longitudine 
scapo funiculoque conjunctim «quali, ovali, subacuminata. 
Antenne in the male very long, reaching nearly to the middle 
of the elytra; scape straight, except for articular hook, strongly 
clubbed at apex; funiculus as long as scape, flexed outwardly on it, 
1st joint long, nearly cylindrical, being strongly produced ex- 
ternally, its inner border hairy, 2nd joint inserted within external 
point of 1st on its anterior side, elongate, cylindrical, joints 83—6 
short, transverse, their outer margins closely applied, their inner 
separated to allow of flexion; club more than three times as long 
as wide, narrow and pointed, attached at its outer basal angle, 
outer edge concave, inner convex at base, thence straight to apex, 
hairy. Antenna of female with scape short, curved, little clubbed; 
funiculus very short, scarcely thickened; club oval, acuminate, 
hairy. Elytra strongly striate.
