locally common. The late Mr. Blanchartl took it in numbers 

 near Lowell, Massachusetts, as has Mr. Frost at South Framing- 

 ham, but the Leng and Liebeck Collections contain only two 

 examples each, while in the Horn Collection there is only a single 

 specimen, and other large collections are not much better off. 

 In the Blanchard Collection it passed nsfemoratus, and one exam- 

 ple at least in the National Museum Collection is included under 

 atomariiis.

Distributions. — A'orlh Carolina: Southern Pines, June (Manee). 



Two females from Maryland in the Nat. Mus. Coll. arc placed
