 It appears scarcely different from the A. nigripes described by Chaudoir himself in 1847. 

 A specimen from Playa Vicente in the Salle collection, named A. obscuripes, does not 

 differ from A. oblongopunctata, and bears no near resemblance to A. rufescens in the 

 sculpture of the elytra.

Subfam. PSEUDOMOBPHINM 







The curious insects which form this subfamily differ in many respects from all other 

 Truncatipennes. One of their chief characters is the possession of a groove or cleft in 

 the cheeks, on each side of the mentum, for the insertion of the base of the antenna?. 

 Other characters are the narrow mesosternum, the contiguous posterior coxse, and the 

 rigid contractile legs. The ligula is horny ; and the paraglossse are not conspicuous as 

 thin membranous appendages, more or less attached to the sides of the ligula, as in 

 most other Truncatipennes. Dr. Horn treats the group as one of the three primary 

 divisions of the Carabida? ; but I hesitate to adopt this view, until the morphological 

 value of the peculiar characters of the group shall have become better understood. 

 They may be only adaptations of structure to the peculiar subcortical habits of the insect, 

 just as the Scaritina?, for example, have certain parts quite as widely modified to suit 

 their fossorial mode of life.
