Length one inch and seven-tenths. 
This species made its appearance here about the 
middle of August. It may at once he distinguished, 
when at rest, from the apicalis, by its divaricating 
wings. It resembles a South American species, 
which, not finding described, I have called undu- 
lata ,* but the abdomen of that insect is much shorter.

Inhabits Missouri, Indiana, and Massachusetts.
