 are black, the metathorax more coarsly rugose, with the median carina 

 quite distinct and extending from base to apex, while the hind tarsi 

 are slightly dusky, the tibial spur being one-third the length of the 

 basal tarsal joint. The wings are hyaline, the marginal cell nearly 

 obsolete, not as long as the width of the radius, the latter prolonged 

 into the disk of the wing with a small fuscous spot at its origin.
