32 NEOTROPICAL PSELAPHIDAE 



5. Trochanters of intermediate legs short, very obliquely articulated with 



femora, so that the latter are near the coxae ; tarsi with two equal 



claws (PI. VI, 9) FARONINI 



(p. 35) 

 Trochanters of intermediate legs with the femora articulated at the 

 distal face, so that the femora are relatively distant from the coxae; 



tarsi with a single claw (PL VI, 8) HOLOZODINI 



(p. 288) 



6. Trochanters of intermediate legs with the femora very obliquely 



articulated, so that the femora are near the coxae (PI. VI, 9) . . . . 7 

 Trochanters of intermediate legs long, more or less clubbed or in- 

 flated distally, with the femora articulated at the distal face, so 

 that the femora are relatively distant from the coxae (PI. VI, 8) . . 13 



7. Mentum very wide, covering mouth and mouth-parts in large part; 



base (cardo) of each maxilla extended obliquely on outer face into 

 a long projection; ventral surface of head usually (but not in- 

 variably) provided with two strong carinae which converge basally 



toward neck to form a Y or a V (PI. VII, I) JUBININI 



(p. 38) 

 Mentum normally small; base of maxillae not so extended; ventral 

 surface of head variably modified but not with a Y or V-carinal 

 pattern (PI. IX, 1) 8 



8. Posterior coxae with median face, which articulates with the tro- 



chanter, either conical or conically produced (PI. VII, 7) (Euplec- 



tini, sensu latiore) EUPLECTINI and TRICHONYCHINI 



(p. 63) 

 Posterior coxae with median face, which articulates with the trochan- 

 ter, either broadly triangular or globular (PI. VII, 6) 9 



9. First visible stemite relatively long: at least as long as the posterior 



coxae, usually extending well beyond these coxae; this sternite al- 

 ways clearly visible for its entire width; with the first stemite 



visible, at least six stemites can be counted 12 



First visible sternite very short: either invisible, or visible laterally 

 but invisible medianly ; or visible laterally and also visible medianly 

 as a short plate or minute tubercle between the coxae ; with the first 

 sternite thus hidden, at least five sternites can be counted 10 



10. Tarsi with a single claw BRACHYGLUTINI 



(p 122) 

 Tarsi with two very unequally developed claws 11 



11. Antennae with their articulations distant, and hence the head is not 



suddenly and strongly constricted anterior of the eyes and not 

 swollen to form a median antennal tubercle; antennae diverse but 

 never having the first segment conspicuously long, hence antennae 

 never geniculate, or sharply bent between the first two segments
