is practically the only species to be taken at Van Cortlandt. Very rarely single 

 specimens are found in company with Notonecta undulata, and this is also true of the 

 occurrence of the latter with the former. It is this insect that is recorded in Dr. 

 Smith's list as N. americana, a bug that occurs only in the southern part of the coun- 

 try. N. variabilis is omitted in the list mentioned. 



N. uhleri Kirkaldy. 



Palisades, N. J., May 5 ; Putnam Co., N. Y., September 5 ; Van Cortlandt 

 Park, New York City, April II, 18 and 25; Fort Lee Dist., N. J., May 14. 



This extremely beautiful crimson and black species, mentioned in my first notes on 

 this family* as likely to occur in this vicinity, I myself had the pleasure of finding at 

 Van Cortlandt Park, making the first published record of the species in this State, 

 and indeed, the first mention of it outside of the type localities. My catch in the 

 localities mentioned constitutes the majority of the specimens in collections. This is 

 a very rare bug, but very readily separable from any other American species. 



N. irrorata Uhler. 



Delair, N. J., Bronx, New York City, September 30; Forest Park, R. I., 

 November 7 ; Palisades, N. J., July 18, August 9 and 23, September 7 and 23, Oc- 

 tober 10 ; Putnam Co., N. Y. , September 5 ; Staten Id., N. Y., August 2 and October 

 2 ; Van Cortlandt Park, New York City, April II, iS and 25, June 6 and July 25 ; 

 Railway R., Cranford, N. J., August 6, 20 and 27 ; Fort Lee Dist., N. J., Septem- 

 ber 18 and October 22. 



This bug is not uncommon in dark waters, hiding among stems and roots grow- 

 ing in the water. 



N. insulata Kirby. 



Delair, N. J.; Palisades, N. J., May 1, August 9 and 23; Staten Id., N. Y., 

 September 26. 



This species is not very abundant. It may at times be found in company with 

 X. irrorata, but ordinarily it seems to seek clear cold pools, where the water is deep 



Genus ANISOPS Spinola. 

 A. elegans Fieber. 



Palisades, N. J., September 7 ; Staten Id., September 26; Van Cortlandt Park, 

 New York City, July 25 ; Rahway R., Cranford, N. J., August 27 ; Fort Lee Dist., 

 N. J., September 18 and October 22. 



This is rather rare in this vicinity and may be found floating in the shallower 

 waters of ponds, near the edges, among the weeds. 



A. sp. (? albidus Champion). 



Delair, N. J. ; Staten Island, N. Y., September 8 and 26, October 25, Novem- 

 ber 11. 



This is the species erroneously identified by me as Anisops platycnemis in my paper 

 cited above. At the time this identification was made, I did not possess Fieber' s
