angular in the recessive specimens, the narrowest point caudad, in the inten- 

 sive individuals the whole area of the disk is infuscate; the caudal margin of 

 the pronotima is much paler in some individuals than in others, while the dai-k 

 disk is in all but the most intensive indi^^dual distinctly divided in two along 

 the median line by a bar of kaiser brown to pale rufous. In the; single excep- 

 tion there is, moreover, a weak indication of such a bar. The pale lateral and 

 cephalic sections of the pronotum are more warm buiT to pale ochraceous-bufT 

 than the general tone. The tegmina have the marginal and greater portions 

 of the scapular fields pale buffy hyaline, the infuscation along the greater por- 

 tion of the mediastine vein very decided. Wings with the veins largely clay 

 color, these saccardo's umber on most of the anterior field and the region of the 

 costal veins and apex of the anterior field is washed with yellow ocher. Dorsal 

 surface of the abdomen washed along the lateral borders with mummy brown; 

 ventral surface of abdomen ochraceous-tawny to mummy brown, the paler 

 individuals are mummy browm laterad and distad, the darker ones fuscous; 

 dorsal apex of abdomen and cerci of male mummj- brown. Limbs ochraceous- 

 buff to pale ochraceous-buff, the spines ferruginous, the coxae marked with 

 prout's brown proximad.
