Anal legs only slightly exceeding the penult ones in length. Slender. 

 The distal article slender, distally rounded, with no trace of claw. 

 Hairs sparse. 



Pairs of legs, 79. 



Length about 54 mm. 



Locality. — Nicaragua: Escondido River about 50 miles from Blue- 

 fields, September, 1892 (C. W. Richmond). Type, M. C. Z. 1731; 

 one specimen. 



Telocricus, gen. nov. 



Head without frontal suture. Basal plate trapeziform, wide, over- 

 lapped by the head. Dorsal plates bisulcate. 



Antennae filiform, long. 



Labrum and first and second maxillae essentially as described for 

 Nesophilus. 



Prehensors large, much exposed from above, projecting widely 

 beyond front margin of head. Claw armed at base with a stout conical 

 black tooth. Femuroid armed toward distal end with a similar 

 stout black conical tooth equally as well chitinized as that of the claw. 



Prosternum without chitinous lines. 



Prescutum also long and narrow, the coxopleurae in dorsal view 

 being much exposed each side of it. 



Ventral pores arranged as in Nesidiphilus but usually fewer and less 

 obvious. 



Last ventral plate very narrow, typically much longer than wide; 

 sides converging caudad. 



Tergite of last pediferous segment unusually narrow, conspicuously 

 narrower than the penult plate, clearly and considerably longer than 

 wide; leaving coxopleurae much exposed from above. 



Coxopleurae strongly inflated and unusually elongate in corre- 

 spondence with the long tergite and prescutum, more or less en- 

 croaching cephalad. Pores very small and very numerous, densest 

 dorsally and ventrally near plates. 



Anaf legs with six large joints distad of coxopleurae and in addition 

 with a minute membranous but clearly defined terminal appendage 

 replacing the claw. 



Genotype.— T. cubae, sp. nov. 



Very close to Nesidiphilus from which it is most readily distinguished 

 by the long and very narrow last tergite and the narrow prescutum 

 which leave the elongate coxopleurae much exposed in dorsal view 

 (Plate 4, fig. 5) as well as by the narrow elongate sternite. The
