ing either end of body, each end of line turned up or down a short

 segments mostly white, the last with a large white triangle each side 

 at base; legs and mandibles pale yellowish, heavily reticulate with 

 black. Venter red-brown, granulate. Dorsum smooth, posterior 

 tubercles rather large; legs long, tarsus I with 6 joints, II with 17, III 

 with 9, and IV with 10 joints. Hind legs of male with femur and 

 tibia slightly curved, the metatarsi sinuate, and at base above with 

 a series of over 20 teeth. Length 6 to 7 mm. 



From Turrialba, Costa Rica (Tristan); nine specimens, all agreeing 

 in the peculiar coloration.

Fortuna; La Palma; Turrialba. 



Cynorta pedalis n. sp. 



Very dark red-brown; a yellow Y-mark as usual, the anterior 

 ends of which terminate in large spots, each with several dark dots, 

 a yellow oblong behind at region of tubercles, and a line from it to each 

 side yellow. Legs yellowish; the trochanters very bright yellow, 

 the femora more or less distinctly banded with dark at base, before 

 middle, beyond middle, and at tip; the tibia? with indistinct bands at 

 base, middle, and tip; the metatarsi with four bands as on the femora; 

 hind tarsi pale yellow, others darker. The dorsum is mostly smooth, 

 the tubercles practically absent ; legs spinulose ; femur IV more strongly 

 so, but hardly with teeth, no large tooth at tip of coxa IV. Tarsus I 

 with 6 joints (three enlarged), II with 11, III with 7, and IV with 8 

 joints. Hind femur about as long as body. Length 6 mm. 



From San Isidro, Costa Rica (Tristan). 



Cynorta tristani n. sp. 



Dark red-brown, marked with yellowish; a Y-mark as usual, the 

 sides and posterior margin narrowly yellow, many small dots above,

 joints, II with 14, III with 8, and IV with 9 joints. Length 5 mm. 



El Higuito, Jesus San Mateo (Pac.) (Biolley and Tristan). The 

 posterior tubercles are much shorter than in C. longispina, to which it 

 is otherwise much related.
