Length of body, 36.5 mm. 54 mm. 



Length of pronotum 7.5 " n.2 " 



Length of tegmen 30.5 " 38.5 " 



Length of caudal femur, 17.5 " 22.8 " 



A paratypic series of tliree males and four females, taken on dates 

 in December, 1904, January, February and March, 1905, have also been 

 examined. One of the females possesses slightly longer tegmina and 

 wings than the others, and in several of the females the frontal costa 

 is slightly constricted ventrad of the sulcus, but otherwise]no important 

 structural variation is noticed. In color the variation noticed is 

 chiefly in the depth of the bay color and the brilliancy of the yellow, 

 the blackish on the internal face of the caudal tibice]^also varying 

 slightly in extent and intensity, being weak in some females and 

 distinctly marked in two of the males.
