DISTRIBUTIONAL NOTES ON HEMIPTEEA, WITH THE 

 DESCRIPTION OF A NEW GERRIS.^ 



By Roland F. Hussey, Forest Hills, Mass. 



During the past three years I have collected Hemiptera in vari- 

 ous parts of Michigan, and in the vicinity of Minneapolis and St. 

 Paul, in Minnesota, and during this time several noteworthy cap- 

 tures have fallen to my lot. Some of these are reported below; 

 records from Berrien County, in the extreme southwestern part of 

 Michigan, have largely been omitted, however, in view of a forth- 

 coming list of the Hemiptera taken there. I have also included 

 here a few records, based on specimens in the collections of the 

 Museum of Zoology of the University of Michigan, which yield 

 important information as to the ranges of a few species. Inasmuch 

 as the distribution of the various known species of Hemiptera in 

 North America is as yet very imperfectly known, such records as 

 these are of considerable value. 



Published records of Hemiptera from Michigan are very few 

 indeed — and the records from Minnesota are equally unsatisfactory. 

 Occasional references to species which have been taken in Michigan 

 are scattered among the reports of the proceedings of various ento- 

 mological societies, but the only important list including non- 

 aquatic forms which has appeared is that of Townsend,^ who 

 reported about eighty-five species from Gonstantine, St. Joseph 

 County. Some of his records, however, must be regarded as doubt- 

 ful: the species reported as Neottiglossa sulcifrons Stal is un- 

 doubtedly N. undata (Say), which he does not list; I have taken 

 Phymata erosa fasciata Gray and P. e. ivolfi Stal in southern 

 Michigan, but I have seen nothing which could be considered P. 

 acutangula Guerin, a Neotropical form which finds its way into 

 Texas; the species listed as Coriscus inscriptus Kirb;f is probably 

 one of the allied species of Nabis, possibly N. roseipennis Renter.
