transverse, the margin broadly obtuse-angulate with the immediate 

 angle broadly rounded, the median section of the margin supplied 

 with a group of long bristle-like hairs : cerci missing : subgenital plate 

 very similar to that of fossicauda, having a large, elongate, quadrate, 

 peg-like projection sinistrad, this, however, being proportionately 

 longer and more compressed than in fossicauda; mesad the distal 

 margin is deeply U-emarginate, dextrad of which is a projection less 

 than one-half the length of the sinistral protuberance, dextral margin 

 arcuate: genital hook resembling that of C. insularis (Walker), but 

 with the curve of the hook more distad in position. Spination of the 

 limbs typical of the genus. 



Allotype : d^ ; same data as the type. 



Differing from the description of the male in the following features. 

 Occipital line weakly arcuate; interspace between the eyes slightly 

 exceeding the greatest depth of the eye and subequal to the distance 

 between the margins of the antennal scrobes. Supra-anal plate 

 transverse, with a distinct, relatively broad, rounded emargination 

 mesad: cerci greatly surpassing the subgenital plate, tapering, 

 moniliform, apex sharply acuminate: subgenital plate ample, the 

 distal section broad, when seen from the ventral aspect not emar- 

 ginate or bilobate, weakly channelled when seen from the caudal 

 aspect. 



General color above pale old gold, the tegmina and lateral portions 

 of the pronotum semihyaline, the wings almost colorless hyaline with 

 the veins tinted. Ventral surface largely cinnamon-buff to ochrace- 

 ous-buff . Head of the ventral color, the face with bister bands which 

 in disposition combine features of the patterns of C reticulosa and 

 craticula, the ventral facial band clearly defined in the allotype, but 

 not indicated in the type, a detached bister point present at each 

 lateral angle of the clypeal base in the allotype but not indicated in 

 the type; eyes kaiser brown, thickly mottled with bister; antennae 

 old gold, becoming bister distad. Pronotum with a pattern in 

 bister much like that of fossicauda but with the lines more connected 

 and complete, the pattern more intensive and therefore more complete 

 in the allotype than in the type. Wing veins, excepting the costal 

 clavations and radiate veins, old gold, the exceptions bister, the clava- 

 tions rather weakly so. Dorsum of the abdomen washed with bister 

 laterad, leaving, however, a very narrow, pale margin; venter of 

 abdomen with a proximal median area of bister and narrow submar- 

 ginal lines of the same color. Tibial spines and the larger femoral 

 spines with their bases surrounded by bister rings.
