It appears prol)able, therefore, that this is another of the hol- 

 arctic species of Hemiptera, and that its range will some day be 

 shown to extend entirely across the American continent, as it is 

 already known to extend across Eurasia. 



Ploiariola hirtipes Banks. A specimen of this Emesine was 

 taken from a spider-web in a cottage on Lindsley Lake, Gogebic 

 County, Michigan, July 20, 1919 (T. H. Hubbell). This species 

 has been reported from a number of localities in New England, 

 but this is the first record from the central part of the continent. 



Sirthenea carinata (Fabricius). There is a single specimen in 

 the Museum of the University of Michigan, collected near Ann 

 Arbor, August 22, 1916 (F. M. Gaige). This species has recently 

 been reported from Illinois by Malloch,^ but without definite 

 locality, and Osborn and Drake have recorded its occurrence in 

 southern and central Ohio. 



Atrachelus cinereus (Fabricius). During the summer of 1918 

 Mr. A. W. Andrews obtained two specimens of this little Reduviid 

 near Detroit, Michigan (July 4, x\,ugust 4). This species was pre- 

 viously known only from the southern and southeastern part of 

 the United States. 



Pagasa pallipes Stal. This Nabid, originally described from 

 Texas, has since been reported from Kansas and Utah. On Au- 

 gust 14, 1918, I took a single specimen at Ingleside, Cheboygan 

 County, near the tip of the lower peninsula of Michigan. This 

 individual lacks the obsolete pale marking on the anterior margin 

 of the pronotum, but otherwise it agrees perfectly with the descrip- 

 tion given by Eeuter and Poppius.^ 



Sericophanes lipidemanni Poppius {^= noctuans Knight). One 

 specimen of this pretty little Mirid came to my light at Minne- 

 apolis, Minnesota, June 13, 1920. This record extends the known 

 range of this form far to the westward. I am indebted to Dr. 

 Knight for identification of this form. 



Gerris argenticollis Parshley. This species is distributed over 

 the eastern part of North America, from the Atlantic seaboard 

 west at least to Michigan and Indiana. I have taken specimens 

 in Michigan at Ann Arbor (April 19, 1919), and in the extreme
