The species has a peculiar facies, owing to its parallel 
form, the length and slenderness of the joints 4-11 of the an- 
tenne,and thecoloration. The surface is slightlyshining. The 
lateral carinee of the elytra extend from the base to beyond 
the middle, and are thickened and raised posteriorly so as to 
give the elytral surface a plane appearance in the central 
portions. 
Malacoscylus albens. 
Angustulus, nigro-fuscus, passim erecte pilosus, antennis articulo 
quarto quintoque basi, pedibus (tarsis tibiisque apice exceptis) 
et vitta laterali elytrorum albo-testaceis ; capite (occipite excepto) 
thoracisque lateribus rufo-testaceis: capite postice subtumido ; 
thorace brevi, antice et postice constrictulo, sparsim grosse punc- 
tato; elytris apice breviter truncatis (angulo exteriore producto), 
subcrebre punctulatis; antennis articulo tertio valde elongato et 
piloso sed haud incrassato, quarto dimidio breviore.

Agrees with Malacoscylus in the great length and pilosity of 
the third antennal joint, although the absence of thickening in 
the same joint gives the insect a different facies. The elytra 
have no elevated lines, and the lateral keel is much thickened ; 
the white lateral vitta is broad from the shoulder to far beyond 
the middle, whence it narrows and terminates in a point before 
the apex. 
Malacoscylus ‘iodinus. 
Elongatus, niger, elytris violaceis sericeo-nitentibus, fascia postmedi- 
ana flava ; capite thoraceque nigro-velutinis, fronte vix convexa ; 
thorace linea utrinque laterali indistincte fulva ; elytris apice 
_ late rotundatis, dorso convexis, utrinque costulis duabus tertia- 
que laterali preeter carinam, lateribus post medium paullulum ex- 
planatis ; pedibus antennisque nigris, coxis fulvis.
