tera. These, in the order of their publication, are: — List of Ileniip- 

 tera from the Muskoka Lake Region of Canada by the present writer: 

 A List of the insects of New Jersey by Prof. J. ]*>. fSmith ; Fauna 

 Ottawaensis, Hemiptera, by Mr. W. H. Harrington ; and a Catalogue 

 of the Hemiptera of Iowa b}^ Prof. Herbert Osborn. The latter is the 

 most extensive and valuable local list of Hemiptera yet published in 

 this country although Mr. Harrington's list is probably the more 

 complete enumeration. Two other recent lists deserve notice here: 

 Mrs. Slosson's notice of the insects taken on the summit of Mt. Wash- 

 ington, and Mr. Cockerell's list of insects from the sub-alpine region 

 of Custer Co., Colorado, both of which include a few Hemiptera. 



The present list enumerates all the described Hemiptera to and 

 including the Jassoidea known to inhabit the vicinity of Buffalo, N. Y, 

 The limit of 70 miles, adopted by Mr. David F. Day in his Catalogue 

 of the Plants of Buffalo and Vicinity, has been followed by the author 

 in the present list as it was in his list of our local Lepidoptera pub- 

 lished in 189 1, but nearly all the species have been captured within 

 a radius of 20 miles from this city. Most of the material here enum- 

 erated and the notes appended are the results of the authors own 

 labors through a period of nine years of collecting with the special 

 object of obtaining a complete representation of our hemipterous 

 fauna. Still many species have been added through the efforts of 

 other local collectors and friends of the author all of which indebted- 

 ness is duly acknowledged in the annotations. But a special 

 acknowledgement is due Mr. Alva H. Kilman of Ridgeway, Ont., who 

 has very generously turned over to the writer all of the Hemiptera 

 taken by him from the unusually rich collecting grounds near his 

 home. These, as will be seen, have added largely to the value and 

 extent of the list. 



It has been deemed inadvisable to include here the Psyllidae, 

 Aphidae and Coccidae as but few of our species are known and any 

 list in these families would be extremely fragmenterj^ This is cer- 

 tainly the largest and probably the most complete local list of Hemip- 

 tera yet published in this country. In addition to the 378 species 

 here enumerated not less than 25 species have been taken that are as 

 yet undescribed and consequently cannot be included. These with 

 a few forms still undetermined can be published later as a supple- 

 mental list together with such species as may be added by future 

 collecting in this vicinity. 



In the annotations the aim has been to give the known dates of 

 capture or periods of general occurrence, the comparative abundance
