utrinque praedita, margine lateral! carinata, interstitiis parce 

 pubescentibus, costis apiceque longius pilosis ; pedes sub-graciles, 

 modice elongati, pubescentes. Long. 13-15 mm ; lat. 6-7 mm. 



The shape of the prothorax is not unlike that of P. flagrans, but it 

 is a little less aculeate laterally in the middle ; the outer posterior 

 margins are less recurved, and the basal one less arcuate ; the elytra 

 are not villose, and the costae are very distinct. It is generally 

 covered with an earthy indumentum, and is on the whole closely 

 allied to H. sabulosus, Sol.

 profunde transversim impressum, oculi convexi, prominentes ; 

 prothorax apice basique sinuatus, lateribus in medio sub-angulatim 

 dilatatis, latitudine maxima duplo brevior, sub-depressus, marginibus 

 laterum acutis valdeque reflexis, plicis brevibus longitudinalibus 

 confertim obsitus, medio linea longitudinal! evanescente ; elytra 

 basi prothoracis latitudine maxima latiora, deinde vix ampliata,
