■326 J. CHESTER BRADLEY. 



Type in Mr. Viereck's collection. 



The author is indebted to Mr. Viereck for contributing the de- 

 scription of this new and interesting species. The third tooth on 

 the tarsal claws is so small as to be perceptible only with the utmost 

 difficulty, but is nevertheless present.

The author here quotes the original description, because the sin- 

 gle specimen that he has seen is in too poor condition to describe. 

 It is slightly smaller than Westwood's, and comes from Canada.

 this group, which the author had suspected before seeing a specimen, 

 is confirmed. 



Habitat. — Georgia, Canada.
