1921] Tlussey — Distributional Notes on Ilemiptem 13 



MuseuDi has one specimen of this species, taken at Fort Davis, 

 Texas, during the summer of 1914 (M. M. Sampson). This Mexi- 

 can Veil id is a new addition to the Hemipterous fauna of the 

 United States. 



Microvelia liuenoi Drake. This little water-strider, recently de- 

 scribed ''^ from the Adirondack Mountains, was taken on a small 

 woodland pool near Three Oaks, Michigan, July 4, 1919; and I 

 also found it coramon at Minneapolis and St. Paul during May 

 and June, 1920, I have compared these specimens with a para- 

 type kindly given me by Professor Drake, and can find no sig- 

 nificant dilTerences. 



Microvclia fontinah's Bneno. T have taken this species in Michi- 

 gan at Ann Arbor (June 10, 1919), from a small pool in a road- 

 side ditch below a spring, and in Berrien County (July, 1919). 



Merragata foveata Drake. Apparently generally distributed 

 over the United States east of the Rocky Mountains. I have taken 

 it in Michigan; and I found several specimens at Minneapolis, 

 Minnesota, on N"oveniber 19, 1918— a cold, bleak day, when no 

 other surface-dwelling Hemiptera were to be found. 



Merragata hrunnea Dral-e. The range of this species extends 

 from Florida to New England, and west at least to Minnesota. I 

 have taken specimens at St. Paul (Nov. 11, 1918), in Berrien and 

 Washtenaw Counties, Michigan, and Miss Butler found it abun- 

 dant at Battle Creek, Michigan, in August, 1920. 



Ranatra protensa Montandon. This species has been much con- 

 fused with the other two species of Eanatra which occur in north- 

 eastern North America. Its range extends from the Atlantic 

 coast west at least to Minnesota. My Michigan specimens are 

 from Washtenaw and Calhoun Counties, and I have seen it from 

 St. Paul and from Cass County in Minnesota. The forms which 

 I reported as this species from Douglas Lake^ are R. americana 

 edentvla Montandon. 



The present species, as I distinguish it, can be separated from 

 R. kirJcaldyi Bueno by its somewhat larger size, its more slender 

 form, and its long and very slender fore femora, which are un- 

 handed; it is smaller than most specimens of R. americana Mon-
