the end of the abdomen. Near the end of the posterior border the 
wings are densely margined with long brown hairs, none on the basal 
portion. On the anterior margin the hairs are rather short and sparse. 
The posterior half of the wing is shaded a decided but not very dark 
brown and is clothed with short hairs, as is also the hind wing; the 
second longitudinal vein has heavy dark brown spines. Hind wings 
nearly as long as the fore, no brown longitudinal shading as in the fore 
pair; on the anterior margin the hairs are rather short and dense. 
Abdomen spindle-shaped, abruptly narrowing at the seventh seg- 
ment. One or two short, weak, curved, inconspicuous spines on the 
lateral margin of each segment. On the eighth and ninth there are 
eight very long stiff spines; two much shorter ones at the end of the 
abdomen.
