462 Mr. C. J. Galian on new Longicorn Goleoptera. 
Mastododera ? simplicicollis , sp. n. 
M. laterali similis, sed difFert prothorace absque tuberculis ; capite 
antice plus elongato ; pedibus antennisque gracilioribus. 
Long. 18, lat. 5| mm. 
Hab . Imerina Mountains. 
The chief structural character by which this species could 
be separated from Mastododera is the absence of tubercles 
from the prothorax. The latter is rounded at the sides, feebly 
dilated in the middle, and narrowly constricted at the base ; 
it is convex above, with evidence of a feeble groove or 
depression along the middle of the disk. The legs are elon- 
gate and rather slender, the posterior femora reach to the 
apex of the elytra, and the last joint of the posterior tarsus is 
longer than the three succeeding joints combined. 
The species is smaller and narrower than M. lateralis , 
Guer., but is coloured in almost exactly the same way. The 
lateral fulvous band of the elytra is, however, narrower and 
stops short before reaching the apex. 
Glaucytes basalts , sp. n. 
Niger ; capite supra prothoraceque dense punctatis ; elytris minus 
dense punctatis, fusco-violaceis basi ru fo- testa ceis, vitta angusta 
suturali griseo-pubescente, apicibus truncatis, quadridentatis ; 
capite fronte vittaque utrinque, thorace subtus, et vitta utrinque 
abdominis argenteo-griseo-pubescentibus. 
Long. 12-15 mm. 
Hab. Fianarantsoa, Imerina Mountains. 
This species has a strong resemblance to G. Jiumeralis , 
Buq., but is more elongated; the prothorax is a little more 
strongly and more thickly punctured, and has no silky, white 
vitta on each side. The elytra are brownish rather than blue 
in colour. 
In the male specimen, from the Imerina Mountains, the 
antennse surpass the apex of the elytra by about the last two 
or three joints. In the females they do not reach to the apex 
of the elytra. 
Cedemon, gen. nov. 
Head moderately concave between the antennal tubercles. 
Front rectangular. Eyes emarginate, coarsely faceted, with 
the lower lobes longer than broad, rounded below. Antennse 
a little longer than the body in the male, barely reaching 
to the apex of the elytra in the female, subfiliforrn and
