110 THE CANADIAN ENTOMOLUGIST. 



COREID^. 



Frotenor Belfragei, Hagl. — Taken at Temiskamingue P. O. It has 

 been redescnbed as Tetrahi?ius Qiiebecensis by Provancher. 



Mega/oiomus jspinosus, Say. — Bear Island, Lake Temagami. Two 

 examples. 



Alydus eiij-inus, Say. — Taken with the preceding, and at Temiskam- 

 ingue Post Office. 



Alydus cofispersus, Montd. — Taken with the foregoing. It may best 

 be distinguished by the dotted membrane. 



Corizus crassicorjiis^ Linn. — Taken at all stations along the Ottawa 

 River, and at Temagami. This is the species I have heretofore deter- 

 mined, I believe correctly, as novceboracensis, Sign. I am indebted to Dr. 

 Horvath for its identification with the common European species. 



Lygaeid^. 



Ortholomus lo7igiceps, Stal. Taken at Bear Island, Lake Temagami. 

 I now use this name for our northern form, which was included by Dr. 

 Uhler in his description of Nysius providus, and which, it seems to me, 

 includes both this species d^\Ci Jainaicensis, Dallas. Genus Ortholomus 

 may be distinguished from Nysius by the rectilinear costal margin of the 

 elytra. 



Nysius thymi, Wolf — Nigger Point, Quinze Lake. On the occasion 

 of his recent visit to Buffalo, Dr. Horvath set aside in my collection as 

 thyvii the Nysius taken by me at Lake Placid, N. Y., and listed as afigus- 

 tatus in my " List of the Hemiptera taken in the Adirondacks." The 

 present specimen taken by Mr. Palmer is a little larger and paler, and may 

 be the true angustatus if that species really be distinct from thymic which 

 I doubt. 



Ischnorhyjichus resedce, Panz. — Temagami, one example. 



Cyvius claviculus, Hahn. — Lake Temiskammgue, two examples. 



Ligyrocoris diffusus, Uhler. — Taken at all stations, and apparently as 

 abundant as in Western New York. This is the species formerly listed as 

 sylvestris, Linn. The latter, if a Ligyrocoris at all, is contractus, Say, and 

 not diffusus. 



Ligyrocoris contractus. Say. — Like the last, this species was taken at 

 all stations where Mr. Palmer collected. It is rare about Buffalo, but be- 

 comes abundant further north.
