Apparently related to R. solitarius Poc. It differs in coloration. 

 The collum, last scutum, and anal valves are black, all narrowly bor- 

 dered with ferruginous. Segments in front of suture blackish brown, 

 the dark color extending caudad of the suture dorsally and the stripe 

 narrowing ventrad to a point below middle; the segments elsewhere 

 more or less ferruginous. Head with vertex dusky, a thick black mark 

 bifurcate below extending ventrad from vertex; clypeus ferruginous. 



Eyes about four times their diameter apart. 



Second tergite not flattened or excavated below. 



Unlike R. solitarius the suture is deep and very sharply defined en- 

 tirely across the dorsum. 



Segments forty-eight or forty-nine as against forty-four in R. soli- 

 tarius. 



Length near 38 mm.; width, 4.5 mm. 



114. Rhinocricus heteroscopus, sp. nov. 



Type. — M. C. Z. 4,373. Paratypc. — M. C. Z. 4,374. Jamaica: 

 Liguanea Plain, 1911. C. T. Brues. 



Similar in general structure to R. solitarius. Differing in color in 

 having a mid-dorsal series of transverse black stripes, each of which is 

 broadly trapeziform and occupies the space in front of the suture. 

 On each side of the black marks a longitudinal reddish or ferruginous 

 band. Below this on each somite a black stripe in front of suture 

 which near the pore occupies the entire space between suture and 

 anterior margin but narrows ventrad leaving a caudal ferruginous 

 border. Anal scutum black. Collum mostly obscure ferruginous, 

 darker along anterior border. Legs and antennae ferruginous.
