C'occonotus hellicosus n. sp. 



Type: female; Cocos Island, Pacific Ocean.* February 38, 1891. 



Allied to C. striolatus Redtenbacher, from St. Vincent, and C. 

 globosus Bruner, from Mexico and Guatemala. From the former 

 it differs in the non-pilose body, in the subdepressed form of the 

 central part of the pronotum, in the broadly emarginate central 

 portion of the posterior margin of the same region, the more curved 

 ovipositor, and the presence of five species on the median femora. 

 From the latter it differs in the non constricted pronotum, the sub- 

 truncate posterior margin of the pronotum, and in the triangular 

 subgenital plate of the female. 



Size rather large; general build robust, body glabrous. Head with the vertex 

 bearing a pair of rotuudate tubercles and an anteriorly directed spinose process; 

 antennae elongate, subfiliform ; eyes spherical, slightly exserted. Pronotum 

 strongly rugulose, the lateral lobes smoother than the dorsal aspect; anterior 

 margin arcuate, posterior subtruucate with a broad central emargination ; lateral 

 lobes slightly longer than deep, the lower margins subtruncate, central portion 

 thickened. Tegmina rather long, moderately broad, apex rounded. Wings 

 ample, reaching almost to the tip of the tegmina. Anterior femora subcorn- 

 pressed, the external lower margins bearing four spines on the distal portion; 

 tibiae quadrate, the lower margins spined. Median femora subcompressed, the 

 external lower margins bearing five spines; tibiae quadrate, the lower margins 

 spined. Posterior femora considerably expanded basally, the external lower 

 margin bearing eight large spines on the distal two-thirds; tibia? quadrate, all 

 margins spined except for a small basal portion, the lower surface with the spines 

 sparser in numbers than the upper surface. Ovipositor slender, curved, the apex 

 accuminate, the lower margin with a well-defined basal shoulder. Subgenital 

 plate triangular-acuminate, deeply and narrowly emarginate apically. 



General color yellowish chocolate color, the tegmina and limbs sprinkled with 

 darker patches of pure chocolate color. Pronotum and head marked with black, 

 which color suffuses the extreme tip on all the spines on the limbs. Wings pale 

 grayish hyaline, the longitudinal viens brownish, the periphery touched with 

 whitish.
