 anteunai. Body slender, cylindrical, with a few transverse dorsal wrinkles. At the 

 end of the first abdominal are two pale, light, small tubercles, situated on a transverse 

 ridge ; a similar pair, but larger, on the end of the fifth abdominal segment. On 

 each segment are two minute dark tubercles. Supra-anal plate long, triangular, with 

 large terminal piliferous warts ; those on the upper side of the anal legs large. 

 The third pair of thoracic feet larger than the others. Anal legs short and broad. 

 General color of the body dark brown, resembling that of the bark of a twig of the

 dorsally. Head semi-oval, flat, green, with yellow lateral lines. The thoracic seg- 

 ments transparent, more tinged with green ; a few small granulations on the anuula- 

 tions of the segments, which are yellowish green laterally aud white dorsally. The 

 seven lateral bands pale yellow, edged with darker green anteriorly, traversing the 

 entire segment above the stigma and continued over six-eighths of the following, in

 tips of the wing-cases, which are also smooth. Anterior leg case with a prominence 

 over the femur. First segment with a smooth dorsal spot, from which wrinkles 

 radiate. Second segment moderately rounded, with interrupted transverse wrinkles 

 dorsally. Third segment with a dark brown central transverse fold, interrupted
