straight. Wings like those of rugosus, the tip infuscated but not mac- 

 ulate. Ground-color of tegmina a pale, almost vinaceous brown; the 

 basal half of the anal field suffused with fuscous except along the anal 

 vein ; the distal half of the costal field more or less suffused and the 

 basal third finely maculate, the proximal part of the discoidal field 

 evenly suffused, the veins and venules of the distal part more or less 

 infuscated apically, and a slight fuscous suffusion near the base. 



"Compared with rugosus the specimen differs relatively little struc- 

 turally or in wing-marking, but radically in the tegminal pattern, 

 which suggests that of tuberculatus , but is much less distinct."
