A neotropical species described from Jamaica and Brazil by Dal- 

 las and again by Uhler (1894, 183) from Grenada, Florida and 

 Cuba as N. inoequalis, a synonym. The Jacksonville specimen, the 

 only one with definite Florida station, is much paler than those 

 from Mexico and San Domingo, with median carina of scu- 

 tellum more distinct.

 Indian Lake, Sabael, N. Y., Aug. 13 — 17 (Barber). An intro- 

 duced European species of northern distribution, its known 



range in this country extending 

 from Quebec and New England 

 west and north to Vernon, B. C,

 much confused with N. cricx and 

 some of its more southern rec- 

 ords belong to that species.
