1886.] REV. H. S. GORHAM ON NEW COLEOPTERA. 157 
with a marginal line round the entire edge uniting with the central 
channel in front ; front margin deeply bisinuate ; sides hardly so much 
rounded in front asin S. chrysomeloides. Elytra longer than in that 
species, thickly and distinctly punctured, hardly any trace of sulcation 
or striation ; shoulders with a callus well raised, ending in a deep red 
spot, another spot near the scutellum, and a third between these two ; 
posteriorly are two small oblong spots (united in the specimen 
described) near the suture about one third from the apex, and another 
between these and the margin. There is a fine sutural stria for the 
whole length of the elytra, and the margin is narrowly reflexed. Legs 
and underside shining black ; femora punctate, but more finely than in 
S. chrysomeloides; anterior pair in the male compressed at the tip 
and with a very small fine calear above the spatulate compression. 
The tubercle on the apical ventral segment is squarish and impressed 
on its top so as to seem faintly bidentate. 
A single male specimen is all that Mr. Lewis secured of this 
species. 
CyMOoNES. 
Characteres plerumque ut in genere Encymon ; differt mesosterno 
haud transverso, prothoracis basi medio vix marginato, sulco 
transverso nullo, antennarum clava elongata, laze articulata, 
articulis nono et decimo viz latioribus, maris tibiarum anticarum 
dente lato. 
I have no doubt that the species for which I propose this new 
genus is the Madagascar representative of Encymon, with which it 
is associated in the form of the mandibles. It has, however, a 
different facies, principally owing to the form of the pronotum, 
which is more convex, with its margins even and scarcely at all 
reflexed. The longitudinal basal sulci are present, but the transverse 
one is quite obsolete. The mode of toothing of the front tibia of 
the male is, moreover, quite different to that of Encymon; in the 
only species of that genus in which I have seen it take place, and 
which is figured by me (Endom. Recitati, tab. f. 10), the tooth is 
small and close to the apex ; here it is wide and strong and near the 
middle of the tibia.

Hab. Madagascar, Betsileo (Cowan). 
Head black, mouth and palpi testaceous, epistoma with a 
few indistinct punctures, crown smooth, antennal orbits raised. 
Antenne piceous, rufo-piceous at the base; the proportion of the joints 
as in Hncymon till the ninth, which with the tenth and apical joints 
are elongate, only rather longer and more widened at their tips than
