Sftodos avara nov. sp. — Length 10 mm. Head yellowish, with gray and

 sector, one at origin of divisialis, (me at forking of divisialis, another at arculus, 

 and a fifth at end of lower branch of divisialis; three transverse gradate veinlets 

 fuscous; upper branch of radial sector forks at the first transverse veinlet; coxiB 

 and abdomen greenish. Legs pale yellowish, with white hairs. 



One specimen, Sherbrooke, Canada, June (L'abbe P. A. Begin).

 of the divisialis, a transverse one at arculus, one at end of thyridial cell, and the 

 fourth at end of thyridial area; but three distinct transverse veinlets in fore 

 wing, one between branches of radial sector, another between radius and upper 

 branch of radial sector, the third in the anal region ; upper branch of radial 

 sector forks a little before tip, lower branch forks near base. 



Many specimens from a stream near Sea Cliff, N. Y., in December,
