Body slender, abdomen little villous. Head narrow, face luteous, 

 between the eyes a broad shining black band, notched on the inferior 

 margin ; vertex luteous ; antenna; as long as head and thorax, slender, 

 elongated, clavate on tip, blackish fuscous, pale in middle ; palpi short, 

 pale ; maxillary ones with the three apical joints equal ; labials not longer, 

 apical joint fusiform ; prothorax elongated, narrower anteriorly, luteous, 

 faintly granulated with black ; thorax dull luteous, above darker ; on each 

 side above the legs a broad black longitudinal band ; below pale ; abdo- 

 men shorter than the wings (I believe I have not seen a male), blackish 

 brown, with a yellow dorsal, transversal band on the middle of each seg- 

 ment, or at least on the second ; the parts in the last segment light brown, 

 with black hairs ; above split longitudinally ; below on each side a short, 

 flat appendage ; legs very long and slender, with short hairs, shining 

 black ; anteriors with base of femur and tip of tibia brown ; hind legs 

 with a luteous band before the tip of femur, or luteous, tip black ; tibia 

 pale, black on tip and after base ; or black, pale at base ; tarsi long, 

 black ; the basal joint sometimes luteous ; spurs luteous, as long as the 

 two basal joints ; apex incurved ; claws luteous ; wings hyaline spotted 

 with fuscous ; front wings with the inner half of an ocellate spot on the 

 middle of the hind margin ; a double spot at the pterostigma, an apical 

 interrupted series, and some dots along the mediana ; hind wings with a 

 larger orbicular spot before the pterostigma, and some spots near the tip 

 and the apical part of the hind margin j venation white, some of the forks 

 and the longitudinal veins interrupted with fuscous. Length of body, 20 

 to 26 mm ; exp. al., 46 to 67 mm. 



Mr. Sanborn, Mass. Agric. Rep., 1862, p. 161, states:— " Specimens 

 of this insect are sometimes found which differ either with the wings not 

 spotted, but hyaline or sprinkled with fuscous, or costal space with a 

 double series of areoles, or without spurs." Apparently Mr. Sanborn has 

 here confounded several species.
