the normal hard and rigid appearing cerci of the other species of 

 the genus. Subgenital plate truncate l:)et\veen the short (Usto- 

 lateral styles. Ovipositor elongate (in the specimen l)efore us 

 13 mm.), nearly straight. The caudal femora are elongate 

 (cT', 13.7-15.7; 9 , 16.2 in the material Ijefore us) and armed with 

 (cf, 3 ami 4 and 4 and "); 9,4 and o, in our material) long, 

 heavy spines. 



Specimens Examined: 3; 2 males ancl 1 female.

Apparently nearest in relationship to C. truncatii.s'''' and allied 

 to C versicolor, but distinctive in coloration and several other 

 important characters given below. 



Type: cf, Itatiba, ?ao Paulo, Brazil. April 10. (J. Lima.) 

 [Academy of Natural Sciences Philadelphia, Type No. 5268.] 



Description of Type. — Size medium, form moderatelj' robust. Coloration 

 verj' distinctive. Head with dorsum of vertex when seen from lateral aspect 

 scarcely ascending (not as much as in versicolor), fastigium of vertex narrow, but 

 about two-thirds as wide as basal antennal joint, two and one-fourth times as 

 long as broad, sides straight and not decidedly convergent. Eyes moderately 

 large, moderately protruding (not as much so as in versicolor). Lateral lobes 

 of pronotum with cei)halic margin convex to the ventro-caudal angle, ventro- 

 cephalic angle very broadly rounded but distinct, ventro-caudal angle sharply 

 rounded and rectangulate, humeral sinus absent, convex callosity very narrow. 

 Tegmina broad and truncate with very broadly rounded apex, covering half 

 the distance from the pronotum to the apices of the cerci, veins distinct, vein- 

 lets subobsolete, tympanum large and distinctly though not strongly longi- 

 tudinal (somewhat more nearly transvei'se than in versicolor); wings small 

 aborted pads broadly rounded at apex, extending half the distance from the 

 tegminal speculum to the apices of the tegmina. Cerci heavy and elongate, 

 proximal portion stout and very brief, mesal portion very ekmgate and much 

 swollen, protluced weakly interno-proximad in a rounded narrow shelf, in the 

 mesal portion of which is situated ventrad a rather heavy tooth directed 

 strongly meso-i)roximad with its sharp apex weakly decurved, distal portion 

 of shaft broad and rather elongate, decidedly dei)resscd, sides subi):irallel to 

 apical portion, where they become (>venly convc^xo-convergent to the \ery 



^^ From d!Xpos=pale antl T€Xos=end, in alhision to the pale and strongly 

 contrasting coloration of the two distal dorsal abdominal segments.
