NOTES ON HEMIPTERA TAKEN BY W. J. PALMER, NEAR 



LAKE TEMAGAMI, ONT. 



BY E. P. VAN DUZEE, BUFFALO, N. Y. 



These notes refer to a small but interesting collection of Hemiptera 

 taken about Lake Temagami in August, 1906, by my friend, Mr. William 

 J. Palmer, of Buffalo. Before starting for a brief vacation trip to 

 northern Ontario, Mr. Palmer very kindly offered to collect Hemiptera 

 for me as time and circumstances would permit. On four days only was 

 he able to do any collecting, but considering the unfavourable conditions, 

 the results were remarkably good, both as to the amount and character of 

 the material brought home. This material represents sixty-two species, 

 including several very interesting forms, and four that may prove to be 

 still undescribed. Among the more interesting species taken may be 

 mentioned Plagiogriathus afimilatus^ Uhler, Dj'cectilacephala AlafiitobiaJia, 

 Ball, Thamnotettix eburata, Van Duzee, Thanuiotettix waldana, Ball, 

 Tha77ifiotettix Smiihit, Van Duzee, and Cicadida lepida, Van Duzee. In 

 the case of five of these six species the known range has been considerably 

 extended. The rediscovery of Tha7n7iotettix ehiirata shows conclusively 

 that this is a boreal species, probably having the southern limit of its 

 range in the Adirondack Mts. It is not unlikely that it will yet be found 

 in the White Mts., and possibly elsewhere in northern New England. 



The particular localities where collections were made by Mr. Palmer, 

 and the dates, are as follows : Red Cedar Lake, August 9th : Fox Island, 

 at the other end of Red Cedar Lake, on August loth ; the lumber camp 

 on Island Lake, August 12th; and Swamp Creek, August 14th. All 

 of these places are within forty or fifty miles of Lake Temagami, in a 

 south-easterly direction. 



Ba?iasa dimidiata^ Say. — One large and deeply-coloured example 

 was taken at the Island Lake lumber camp on August 12th. 



Podisus serieventris, Uhler. — One fine large specimen from Red 

 Cedar Lake, August 9th. As stated in my Annotated List of North 

 America Pentatomidse. I distinguish this species from 77iaculiveiitris by 

 the short ventral spine, less acute humeri, etc. The present example is 

 fully as large as any I have seen of 77iacidive7ii7-is, and is much more deeply 

 coloured, with the wings of a rich metallic green^ and some of the 

 ptmctures, especially on the pronotum, tinged with the same colour. 



Ligyrocoris co7itractus, Say. — One specimen from Red Cedar Lake^ 

 August 9th, and one from Swamp Creek, both females. I have this 



December, 1906
