General coloration buffy, tinged with buckthorn brown. Head buffy with four 

 vertical lines on occiput, a moderately broad band between eyes, a moderately broad 

 band, convex ventrad, between ocelli and face maculate with blackish brown. ^^ 

 Pronotum with disk ochraceous-buff, with suffusions and picturing of tawny and 

 dots of mars brown; in other individuals, instead, chestnut brown and prout's 

 brown: pattern of the same general type as that found in acanthastylata. Teg- 

 mina transparent, buckthorn brown; area of dextral tegmen concealed when at 

 rest, with veinlets dresden brown. Wings hyaline, with a very faint brownish 

 tinge, this decided, prout's brown, in narrow area between intercalated triangle 

 and axillary vein; area of distal portion of costal veins buffy in type, this only 

 weakly indicated as a very narrow suffusion, proximad of the enlarged apices of the 

 costal veins, in other specimens; radiate field in some lights distinctly iridescent, as 

 in all other species of the Impar Group before us. Dorsal surface of abdomen 

 ochraceous-buff, washed with cinnamon brown, thi§ deepening to mummy brown 

 distad. Cerci ochraceous-buff, bases and medio-distal joints washed with mummy 

 brown. Ventral surface and limbs ochraceous-buff, *< with a striking shining black 

 maculation proximo-mesad on the abdomen. 



Several specimens before us are of recessive coloration, in these 

 the facial markings, normally decided in this species, are weakly 

 defined or subobsolete. The delicate pronotal markings likewise 

 show reduction in both extent and intensity in these examples. 



In addition to the type and allotype, the following series is con- 

 sidered paratypic.

83 Several specimens before us have the head somewhat discolored in drying, the 

 markings probably more suffused than in life, the small ocelli now not strikingly pale. 



*• The limbs are clearly discolored, ochraceous tawny, in the type.
