244 PROCEEDINGS OF THE ACADEMY OF '[May-Oct., 



internal, six to fifteen; ventro-external, twenty to twenty-six; ventro- 

 internal, twenty-one to twenty-nine; ventro-mcdian carina, ten 

 to eleven, no lobes present on the margins; genicular lobes spinose, 

 subdepressecl; caudal tibiae faintly shorter than the four prox- 

 imal abdominal segments, the margins armed and developed as 

 on the median tibiae; caudal metatarsi slightly longer than the re- 

 maining tarsal joints, evenly cristato-lobate dorsad, the distal ex- 

 tremity of the lobe with three to six minute teeth. 



General coloration pinkish-cinnamon to kaiser-brown (unciues- 

 tionably green or a more uniform brownish in life), the femora, par- 

 ticularly the caudal pair, weakly washed with dark livid-purple, 

 while the tibiae are in part weakly light fluorite-green' to dull mala- 

 chite-green, this probably a trace of the original coloration. 



Length of body, 264.6 mm.; length of head, 12.5; length of pro- 

 notum, 7.3; length of mesonotum, 59.5; length of metanotum (in- 

 cluding median segment), 40.3; length of median segment, 19.7; 

 length of cephalic femur, 74; length of median femur, 56.5; length 

 of median tibia, 64.3; length of caudal femur, 59.4; length of caudal 

 tibia, 77.5; length of operculum, 24.2. 



The type of this striking species is unique.

Rio de Janeiro. One male, one female. [M. C. Z.] 

 The female specimen is somewhat smaller than the original meas- 

 urements and is minus the caudal limbs, but it is clearly the opposite 

 «ex of the male now before us, and, when compared with a pair of 

 C. radula, their close relationship to the latter species is very appar- 

 ent. The specimens measure as follows:
