DESCRIPTION OF TWO NEW SPECIES OF ORTHOPTERA 



FROM PERU. 



BY A. N. CAUDELL. 

 Bureau of Entomology, U .S. Dapt. Agriculture, Washington, D. C. 



Among Orthoptera recently received from C. H. T. Town- 

 send, Piura, Peru, for determination were the following two species 

 which seem to be undescribed. 



Plectoptera huascaray, n. sp. 



Description. — d^ (the 9 unknown) : Most closely allied to the 

 P. niicans of Bolivar from the West Indies but is decidedly larger. 

 Is also allied to P. picta S. and Z. but has darker elytra and wings 

 and the pronotal disk is not margined in front. 



General colour black variegated with brown. Head black with 

 a small ashy variegation and transverse stripe about the insertion 

 of the antennae; antennae black, the first few segments lighter. 

 Pronotal disk broadly elliptical, black in colour with the lateral 

 margins broadly and the posterior margin very narrowly and 

 interruptedly bordered with yellow. Elytra brown and black, the 

 humeral area and a large subquadrate spot at about the apical 

 third of the posterior margin black, the rest yellowish brown 

 flecked with black, the black flecks assuming a definite elongate 

 shape and regular arrangement along the posterior half of the 

 costal margin. Wings large, smoky brown, the apical area nearly 

 black, the costal margin almost entirely so; the apical area is very 

 large, being nearly as long as the rest of the wing, and the base is 

 straight, not at all angulate. Abdomen black; supra-anal plate 

 twice as broad as long, mesially produced apically and narrowly
