Hab. — -A male from Florida, by Uhler ; a male from Cumberland Gap, 

 Ky.; a male from New Haven, Conn., by E. Harrison ; a male from Fal- 

 mouth, Mass., July 22; a male from Middleboro, Mass.; besides I have 

 seen some fresh specimens collected by B. P. Mann in June, in Martha's 

 Vineyard. The distribution from Florida to Martha's Vineyard Isl. is 

 very large. This species is until now the only one known from the U. S. 



I have before me a sketch of a young larva of an Ascalaphide, made 

 more than a dozen years ago, which was shown to me by Mr. Riley ; per- 

 haps it belongs to this species, at least it differs from all larvae known,
