1921] Hussey — Distributional Notes on Hemiptera 9 



N. fahricii Fieber (= glauca Linne) and as N. americana Fabri- 

 cius ('= indica Linne), a species occurring in the southwestern 

 United States and Mexico, can be identified only by examination 

 of the specimens. The same is true of the single Corixid species 

 listed, Arcfocorisa calva (Say). 



However, recent work in various parts of Michigan has added 

 materially to our knowledge of the Hemipterous fauna of the state. 

 Collections have been made in four localities in the lower peninsula, 

 and in the western part of the upper peninsula, along the Wis- 

 consin border. These studies will be reported separately in the 

 near future. 



Acknowledgements are due to Messrs. H. G. Barber, J. K. de la 

 Torre Bueno, H. M. Parshley, and H. H. Knight for identification 

 of several of the species listed below, and to Mr. F. M. Gaige of 

 the Museum of Zoology of the University of Michigan for permis- 

 sion to include several records here. 



Sciocons micro phth.ahiuis Flor. This Pentatomid, which was 

 first described in 1860 from the Baltic region, is widely distributed 

 in the Palfearctic region, where it has been recorded from Europe, 

 Eussia, tlie C'aucasus district, Siberia and China. It was first 

 reported in America by Van Duzee in 1904, from Mt. Washington, 

 New Hampshire, and it has since been recorded twice from Maine. 

 Hart^ lists it as occurring at Duluth, ]\Iinnesota, and in the "Lake 

 Superior region." Stoner"* has recently given an account of its 

 capture at Douglas Lake, Cheboygan County, Michigan. 



I have also taken this species at Douglas Lake, from roadside 

 grasses in a lowland stand of arbor-vitae, balsam fir, birch, and 

 aspen ; and, while I was at the University of Minnesota, Professor 

 0. W. Oestlund very kindly gave me one of five specimens which 

 he took in tlie vicinity of Minneapolis a number of years ago. 



Very recently I have received from the Museum of Zoology of 

 the University of Michigan a number of Hemiptera collected in 

 North Dakota by Mr. T. H.' Hubbell during the summer of 1920. 

 Among these was a single specimen of 8. microphtlialmiis, taken 

 on the arid top of a butte in the Bad Lands near Amidon, Slope 

 County, in the southwest corner of the state, August 21, 1920.
