Psyche 
[March- June 
Cebrio bruesi sp. n. 
Male. Slender, tapering behind. Dark brown. Antennae, legs, 
and abdomen paler. Possibly close to emarginatus Schaeffer 
but it differs from that species in the absence of a “moderately 
deep” excavation of the apex of the last abdominal segment. 
Head quite densely and moderately deeply punctured. Front 
concave, with a pair of lateral impressions in the concavity. A 
feeble ridge runs almost straight across between the bases of the 
antennae. Sides of labrum almost parallel. Apex deeply, tri- 
angularly excavated. Mandibles moderate in size, a little more 
slender than in bicolor. Last segment of the maxillary palpi as 
long as the third, not greatly broadened apically and obliquely 
truncated. Third segment of the antennae almost twice as long 
as the fourth. The antennae are moderately slender, the anten- 
nal processes short. Process of last segment very faint, obtuse. 
Pronotum more densely and finely punctured than the head. 
Posterior angles divergent. Striae of the elytra distinct for the 
whole length; the strial punctures not very distinct. Prosternal 
process broad. Apex of last abdominal sternite just perceptibly 
excavated. Length, 13-16 mm. Width, across base of elytra, 
3J4-4 mm.
