ble, the male sexual characters, when visible, affecting the abdominal 

 segments only Stil1)US 



Basal joint of the posterior tarsi longer than the second ; elytra with two 

 discal striae. 

 Prosternal process inflexed at apex, devoid of terminal setae. 



Basal joint of the posterior tarsi extremely elongate, much longer than 

 the entire remainder ; mesosternura not extending behind the middle 

 acetabula except as a fine marginal bead ; sexual differences in the 



posterior legs not observable LiitoclirilS 



Basal joint elongate but distinctly shorter than the remaining joints com- 

 bined ; mesosternum extending behind the middle acetabula, where it 

 is moderately developed ; sexual differences in the posterior legs con- 

 spicuous Liitochropus 



Prosternal process not inflexed, having a free acute edge OclirolitltS 



TOLYPHUS Erichs. 



The antennae in this genus are unusually short and robust, the 

 two basal joints of the club strongly transverse. The prosternal 

 process is rather wide, gradually inflexed at apex, and margined 

 throughout the sides and apex with a fine strong convex bead ; it 

 is not in the least setose, and, in repose, rests against the vertical 

 portion of the mesosternum. The metasternal process is rather 

 narrower than in Phalacrus, but similar in form and extent, the 

 mesosternum forming a fine apical and lateral bead. The mesoster- 

 num behind the middle acetabula forms a fine bead as in Phalacrus. 



The terminal spurs of the posterior tibiae are short, although 

 projecting well beyond the terminal fringe of spinules; they are 

 very sti'ongly dilated toward base and pointed at apex. 



The singular structure of the eyes mentioned in the table, together 

 with the structure of the tibial spurs, isolates Tolyphus widely from 

 the entire remainder of the family, and constitutes of it a group 

 equivalent to either the Phalacri or Olibri. The first of these 

 characters, neither of which has apparently been before noticed, is 

 of exceedingly rare occurrence in the Coleoptera ; the second is 

 often seen as a modification of the anterior spurs in the Harpalini. 



The observations above noted were made upon T. granulatus 

 Guer. from Spain. No species has yet occurred outside of the 

 Mediterranean province of the paliearctic fauna.
