" Of much narrower and less ovate form than C. elevatus or any other species of the 

 genus, resembling at first sight a Carabus, e. g. C. preslii. The explanated and 

 turned-up margins of the thorax and base of the elytra are of the same nature as in 

 C. excavatus, but much narrower, and the thorax is rather strongly narrowed behind. 

 The epipleurse of the elytra are more feebly rugose-punctate than in C. excavatus ; and 

 the sides of the metathorax and basal ventral segments, instead of being sculptured as 

 in that species, are smooth."

P. mexicano paullo major, relative latior. Lsevis, castaneo-rufus, an tennis (scapo castaneo excepto), tibiis et 

 tarsis fuscis ; capite supra punctulato et inaequali, frontis margine ab oculi margine posteriori usque ad 

 epistoma valde et acute elevato et angulato, collo depresso ; antennis elongatis, articulis 4°-10 m oblongis 

 compressis; thorace fere sicut in P. mexicano cordato-quadrato, sed latiori, angulis anterioribus valde 

 prominentibus acutisque, margine laterali haud crenato, integro, angulis posticis exstantibus acutis, dorso 

 subtiliter sparsim punctulato ; elytris humeris dentatis, dorso vix perspicue punctulato nee striato ; 



femoribus anticis medio subtus obtuse angulatis.

Similar in general form and smooth surface to P. mexicanus, but relatively broader, 



less shining, and further distinguished by the strongly raised and acute margins of the 

 forehead and the unusual (for this genus) length of the antennae, which reach to one

third the length of the elytra. The antennae are relatively longer than in the Chilian 

 species P. marginicollis and biguttatus, but differ from them in the more compressed, 



g joints 4-10, which are further distinguished by being naked on their flattened 





sides
