parallel to the second sulcus, considerably expanding between the 

 second and third, very slightly expanding to the caudal margin; 

 cephaHc margin subtruncate, caudal margin obtuse-angulate, more 

 rounded in the male than in the female; first transverse sulcus obsolete; 

 lateral lobes of the pronotum with the dorsal length slightly greater 

 than the depth, ventral margin with a considerable cephalic emargina- 

 tion. Interspace between the mesosternal lobes moderately longi- 

 tudinal in the male, slightly so in the female; metasternal lobes con- 

 tiguous caudad in the male, separated by a space about a fourth the 

 width of the mesosternal interspace in the female. Tegmina consid- 

 erably exceeding the tips of the caudal femora in length, apex rounded, 

 costal margin with a very narrow and slight proximal lobe; hyaline 

 in the proximal third ; intercalary vein irregular and extending the whole 

 length of the area, becoming lost in irregular reticulations ; ulnar area 

 with a distinct longitudinal dividing vein in both sexes. Wings ample. 

 Abdomen considerably compressed; subgenital plate compressed with 

 a blunt apical tubercle. Caudal femora robust, the pagina deeply 

 and strongly sculptured; caudal tibise distinctly, but not greatly, 

 shorter than the femora, the lateral margins armed with ten or eleven 

 spines ; tarsi with large arolia. 



General color shading from tawny-olive to burnt umber. Head and 

 pronotum with postocular bars of vandyke brown, broad and dark 

 in the male, quite narrow and light in the female. Dorsum of the 

 head, pronotum and closed tegmina lighter than the lateral aspects, 

 tawny-olive in the female, bay in the male. Venter wood brown. 

 Limbs varying shades of the general color; tarsi very pale viridian 

 green, with the base of the first, the whole second, the apex of the third, 

 arolium and tips of the claws black; spines on the tibiae tipped with 



black.

A paratypic series of two females have also been examined (Septem- 

 ber 7 and 14, 1900), and differ in no important characters from the 

 type. One specimen represents a darker and more sooty type of color- 

 ation than the other.
