The narrow prothorax of this insect distinguishes it from the 
great majority of the species of this genus. The very setose legs, 
and clava of the antennz, the latter not larger than the head and 
closely punctured, the tibize furnished with two spurs, and the 
abdomen with two diverging horny points at the apex beneath, are 
also amongst its leading characters. The head is opaque, but not 
distinctly punctured, and the tarsi are as thick as the tibie. The 
structure of the palpi proves that this species is a species of the 
present genus. The insect figured by M. Guérin under the name 
of P. cornutus, Chevrolat, is identical with the present species, as, 
indeed, M. Chevrolat has since ascertained, the name armatus 
being now attached to the specimen in his collection. Figures 2, 
2a, and 2 6, are copied from M. Guérin’s figures ; the spine of the 
head is, however, much less acute than in the specimen represented 
at fig. 6. 
Fig. 1a represents the head seen sideways; 1 0, the maxillary 
palpus; 1c, the labial palpus; 1 d, the antenna; 1 e, one of the tarsi.

Obscure rufo-castaneus, elytris magis rufescentibus, capite oblongo obscuro punctato, antenna- 
rum clava punctatissima setulosa, rotundato-ovali, basi extus hamato, marginibus acutis
