Differs inter alia fi’om Megamerus in the shape of the apical 
joint of the maxillary palpi, from Cheiloxena in the nondentate 
sides of the prothorax, from DvJboxdaia in the strongly convex 
eyes, from Prionesthis in the dentate hind femora, from Carpopha- 
gus, Diphanops, Mecynodera, and Ainetalla in the long antennae, 
and from Polyoptilus in the dense clothing of pubescence.

Sat elongata ; ferniginea ; dense albido-pubescens ; elytris costis 
3 vel 4 latis obscnris instructis ; his nonnihil denudatis, postice 
obsoletis. [Long. 4-6, lat. 11-1? lines. 
The structure of the head and its organs is almost exactly as in 
Polyoptilus Lacordairei, Germ. The surface is entirely clothed 
with dense whitish hair beneath which it appears to be finely 
punctulate. The basal joint of the antennae is about equal 
to the tliird, — joint 2 short, 3 twice 2, 4 nearly t’wice 3, 5 scarcely 
longer than 4, 6 equal to 5, 7-11 successively longer, the appendi- 
culate part of 1 1 very short. The prothorax closely resembles 
that of Polyoptilus in structure, the suture between the pronotum 
and prosternum running (as in that genus) on the undereide but 
appearing more conspicuous ; the prothorax is as long as wide, its 
greatest width immediately in front of its base, its sides concave 
in the middle, and convergent in the extreme front, so that a 
little behind the front the segment is not much narrower than at 
its Arfdest ; there is a denuded and slightly elevated narrow line 
(abbrerfated at both ends) running down the middle ; the angles 
are all obsolete. The elytra are not at all punctulate-striate but 
(as far as I can observe under the dense pubescence) are I'ather 
closely punctured with a confused mixture of large and small 
punctures ; three or four ill-defined wide rounded costje originate 
at or near the base but do not extend much beyond the middle of 
the elytra hind wards (very similar costje exist in Polyoptilus 
Lacordairei), which are almost devoid of pubescence and thus show 
a ferruginous colour in contrast with the nearly white pubescence, 
girfng the elyti-a the general appearance of being nearly white 
with several obscure wide reddish longitudinal vittaj in the anterior
