DIVISION II. MACROSCELIA (Raffray, 1890) 



The preceding nine tribes form the first division of the subfamily Psel- 

 aphinae, all having the coxae subcontiguous to their respective femora as a 

 consequence of the short, obliquely articulated trochanter. 



The Macroscelia have the intermediate trochanters elongate obconical 

 to clubbed apically, with the articulation of the respective femur distinctly 

 apical, and consequently the intermediate coxa and femur are relatively distant. 

 This division holds fewer tribes, genera and species. 



Tribe 10. Pselaphini 



The Pselaphini are poorly represented in the neotropics by two genera 

 and eight species. They may be differentiated from other macrosceline tribes 

 by (1) fourth (distal) segment of the maxillary palpi is very long, slender 

 and pedunculate at base, inflated and clubbed at apex, and (2) the tarsi are 

 normally formed, with the second tarsomere never bilobed, the third (distal) 

 tarsomere having only a single large claw. The two genera may be separated 

 as follows: 



Distal segment of the maxillary palpi without a sulcus on the external 

 face, or if present it is very short and restricted to the apex; vertex 

 with a deep, median, longitudinal sulcus from near anterior margin 

 of eyes to apex of antennal tubercle; abdomen relatively long, nearly 



as long as elytra PSELAPHUS 



Distal segment of the maxillary palpi with an entire longitudinal sul- 

 cus on the external face from base to apex; vertex with no longi- 

 tudinal sulcus, at most the apical margin of antennal tubercle in- 

 cised; abdomen relatively short, much shorter than elytra
