256 BRAZILIAN ORTHOPTERA 



in the length: costal margin well arouate proximad, thence straight with a 

 very faint sinuation; sutural margin arcuate, well flattened on median half; 

 apex rounded acute: marginal field moderately wide, reaching to distal two- 

 fifths of the tegmen, deplanate; scapular field broad, regularly narrowing 

 distad from the middle of the tegmen, where the width of the field is 

 almost one-half of the tegminal width; anal field acute, elongate pyri- 

 form: venation decided, elevated: mediastine vein arcuate distad; humeral 

 vein sinuate mesad, much the same as but more decidedly than the costal 

 margin, costal veins numbering about fourteen, the distal ones hard to dis- 

 tinguish from intercalated false nervures, which are as strongly indicated as the 

 costal veins themselves and are between all the latter, on the internal side the 

 humeral vein bears no true rami; median vein biraniose, the rami in general 

 longitudinal; ulnar vein biramose, the rami in general longitudinal; anal vein 

 in distal half straight, hardly arcuate at its apex, joining the sutural margin 

 slightly proximad of the proximal third; axillary veins three to four in number, 

 the fourth adventitious, being indicated on the sinistral and not on the dextral 

 tegmen. Wing with anterior field damaged; appendicular field small, also 

 damaged: costal veins at least ten in number, bent in direction, not clavate; 

 discoidal and median veins straight, simple; ulnar vein with a number of 

 rectangularly diverging, short, regularly placed, incomplete cross veins 

 caudad in distal section; axillary vein biramose: medio-discoidal area of medium 

 regular width, divided into a number of subquadrate interspaces by straight 

 cross veins; medio-ulnar area in general narrower than the medio-discoidal area, 

 divided distad into subquadrate interspaces. Abdomen regularly narrowing 

 distad; antepenultimate dorsal segment with a circular, depressed, glandular 

 area, which is deeper proximad than distad and divided into two fairly well 

 marked divisions by a medio-longitudinal fold: supra-anal plate transverse, 

 the greatest length contained slightly more than twice in the greatest width, 

 distal margin sinuato-convergent laterad to a median subtruncate section, 

 which has a very faint median emargination and which passes roimdly into the 

 lateral sections of the same margin: cerci damaged: subgenital plate with the 

 distal margin broadly arcuato-emarginate to receive each style, which are 

 closely placed and between whose sockets the margin is obtuse-angulate; styles 

 very similar to those of C. lata but proportionately heavier and more twisted. 

 Femora unspined ventrad, there supplied with hairs, disto-ventral spine of the 

 cephalic face of the cephalic femora very elongate, disto-ventral spines of 

 both faces of the median and caudal femora shorter, dorsal genicular spine 

 present on median and caudal femora, very elongate: arolia present. 



General color of the disk of the pronotum, anal and discoidal and narrow 

 juxta-discoidal edging of the scapular fields orange rufous; lateral portions of 

 pronotum and marginal and remainder of scapular fields hyaline. Head 

 blackish-fuscous, a transverse band of dull sulphur yellow at narrowest point of 

 interocular space, immediately ventrad of which is a very fine hair line of the 

 same color, which line also margins the eyes ventrad for a short distance; 

 antennae of the color of the head; palpi, labrum and distal half of clypeus light 

 ochraceo US-buff; eyes prout's brown mottled with fuscous. Pronotum with 

 the cephalic margin immediately cephalad of the disk clouded with napthalene 

 yellow, caudal margin for its full width narrowly clouded with wliito. 'I'egmina
