Mr. C. J. Galian on new Longicorn Coleoptera. 463 
subc> lindric, with the scape clavate, reaching almost to 
the middle of the prothorax, with the third joint longer 
than the scape, the fourth rather shorter than the scape, 
the fifth and succeeding joints gradually decreasing in 
length. Prothorax with a distinct conical tubercle at the 
middle of each side, feebly tubercled on the disk. Elytra 
rather short, regularly convex, gradually narrowed and sub- 
truncate behind: the shoulders slightly projecting. Femora 
clavate-fusiform. Intermediate tibiae entire. Claws of tarsi 
divergent. Anterior cotyloid cavities strongly angulate 
externally. Prosternal process simply arched. Intermediate 
cotyloid cavities open on the outside. 
The female differs from the male by its slightly shorter 
antennas, its somewhat shorter elytra, and by having the last 
abdominal ventral segment longer and sinuately emarginate 
at the apex. (In the male this segment is rounded and not 
emarginate.) 
In the difficulty of finding a more satisfactory position for 
this genus, 1 am content to place it near Phymasterna . From 
Phymasterna and all the genera of the same group it differs 
by the complete absence of any notch or groove from the 
intermediate tibiae, by the more elongate and coarsely granu- 
lated eyes, and by the club-like form of the scape of the 
antennas. The general form of the single species of the 
genus is suggestive also of certain genera of the Crossotides ; 
but, owing to the structure of the claws, it can scarcely be 
admitted into that group. 
Cedemon tristis, sp. n. 
Nigro-velutinus, tarsis et annulis antennarum albo-flavescentibus 
exeeptis ; prothorace supra leviter trituberculato ; elytris sparsim 
punctatis. 
Long. 16, lat. 7 mm. ( $ ), long. 14, lat. 6 mm. ( J ). 
Hab . Imerina Mountains. 
With a deep uniform velvety black pubescence. Head 
sparsely and not very distinctly punctured ; with a very fine 
median impressed line running from the base to the occiput. 
Antennas with the eighth and eleventh joints wholly, and the 
basal halves of the third, fourth, and sixth yellowish testa- 
ceous and clothed with a whitish pubescence ; the rest of 
the antennae velvety black. Prothorax with three feeble 
tubercles above — two anterior, one median posterior. Elytra 
each a little prominent at the middle of the base, as well as 
at the shoulder, sparsely punctured on the basal half, sub- 
truncate at the apex. Tarsi (the claws excepted) testaceous
