516 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
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. 
Locatity.— Nicaragua: Escondido River about 50 miles from Blue- 
fields, September, 1892 (C. W. Richmond). Typr, 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. 
Anal legs with six large joints distad of coxopleurae and in addition: 
with a minute membranous but clearly defined terminal appendage 
replacing the claw. 
GENOTYPE.— 7’. 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
