as the prothorax and provided with a long neck, parallel from the vertex 
to the epistome, the eyes ovate, not reniform, epistome shorter than the 
labrum which is slightly attenuate, mandibles very long, slightly tapering 
and hooked at tip ; antennae very long, slender, joints sub-cylindrical, 
occasionally angular inwardly at tip, ultimate joint longer than the 
penultimate ; prothorax longer or as long as broad, strongly tapering 
in the anterior part, ovate globose in the posterior ; scutellum long, 
oblong ; elytra broader than the prothorax, elongated, sub-cylindrical, 
but occasionally plane on the dorsal part (planidorsis), not singly rounded 
at apex, without costules, always pubescent ; last abdominal segment 
of ^ deeply scooped ; legs long, tarsi also long, bristly laterally, claws 
corneous, each one very deeply cleft as in Cantharis, and likewise not 
pectinate ; spurs of hind tibiae either contiguous or not at the base, 
equally long or the inner one longer, sometimes one or both are 
sub-spatulate or truncate diagonally and sharp at apex. 
The species included in this genus have not been recorded from 
beyond the South African limit. They are mostly found in the western 
part of the Cape Colony, but one species is recorded from the eastern 
provinces. They are floricolous, and appear for a short time only. 
Nothing is known of their habits.
