Mr. C. J. Galian on new Longicorn Coleoptera. 459 
spined in the middle, with the anterior and posterior angles 
sharply rounded and destitute of any trace of a spine. Elytra 
fulvous testaceous, somewhat darker towards the base, thickly 
punctured, and each with four or five feebly raised lines. 
Body underneath light reddish brown, with a rather sparse 
tawny pi.bescence, which is somewhat thicker and longer on 
the breast. Antennae with the third joint a little shorter than 
the fourth, the ramus of the third joint as long as the body of 
the joint, the ramus of the fourth joint about as long as the 
body of the fifth joint, and the rami of joints fifth to ninth each 
longer than the body of the succeeding joint. 
This species in size, form, punctuation, and pubescence 
agrees pretty closely with C. flabellicorn is, Serv. The elytra 
and the underside of the body are, however, much lighter in 
colour ; the eyes below are not more than half as far apart, 
and the structure of the antennae is different. In the seven 
male specimens of C. Jlabellicornis before me the third joint of 
the antennae is in every case about equal to or a little longer 
than the fourth, and is not furnished with a distinct ramus, 
but is merely produced at its inner apical termination into a 
very short angular process ; the ramus of the fourth joint is 
never longer than half the fifth joint, and in no case is the 
ramus of any joint longer than the body of the succeeding 
joint. 
Tereticus antennal is , sp. n. 
Fuscus, creberrime punctulatus ; capite, prothoraceque cum pectore 
fulvo-villosis ; elytris fulvo-brunoeis vel fuseis, pube fulva leviter 
obtectis ; an tennis dimidium corporis vix attingentibus, articulis 
a secundo ad decimum gradatim crescentibus, ramis longissimis, 
articulo undecimo sex prmcedentibus conjunctis aequali. . 
Hob . Imerina Mountains. 
Dark brown, closely and finely punctured. Head, pro- 
thorax, and breast with a somewhat sparse tawny villosity. 
Elytra with but the faintest trace of costse ; clothed with a 
rather sparse fulvous pubescence. Antennae with the joints 
from the second to the tenth gradually increasing in length 
and each provided with a very long ramus ; the tenth joint 
about equal in length to the scape, the eleventh as long as 
the six preceding taken together. 
This species resembles the same sex of T. pectinicornis , 
Waterh., but is easily distinguished by the structure of the 
antennae. In pectinicornis the branches of the antennal joints 
are much shorter and the third joint is almost as long as the 
scape and longer than any of the succeeding joints, the eleventh 
excepted.
