In specimens preserved for some time in alcohol, all traces of the original color are 

 lost, the whole animal turning to a testaceous hue. The coloration of a very large 

 fresh female befoi'e me is as follows : — 



General tint is a very light olive-brown ; median stripe is black, continuous, strongly 

 defined, and extending from between the eyes to the posterior border of the pe- 

 nultimate scutum, where it abruptly terminates. Lateral stripes are black, strongly 

 defined, interrupted, and extending from the eyes to the posterior border of the last 

 scutum. The interruptions are so arranged that most of the scuta present three 

 blotches on each side. Anterior portion of the head with two stripes converging 

 anteriorly to the median line. In front of these there is a sub-round marking pro- 

 longed anteriorly. Most of the femora are provided with a very incomplete greenish 

 black annulus, which is, however, complete on the last pair. Tibia and tarsi biannu- 

 lated. Dorsal stomata bordered with brilliant white. 



Authorities differ as to the validity of this species. We have never seen C. 

 coleoptrata, and therefore cannot offer an opinion.

Color of the specimen is at present brown, of an obscure olivaceous tint. When 

 alive, it was probably more decided^ greenish. The tuberosities on the posterior
