FAUNA OTTAWAENSIS. V-^^X^jAStfji//^' 



HEMIPTKRA. \-^ .<* V W 



By W. Hague Harrington. 

 In the report of the Entomoluyical l-!ranch for 1890 (Ottawa 

 Naturalist, Vol. V, 193) it was ])ron"iised that a preliminary list of 

 local Hemiptera would be published. The collection and study of our 

 species has been of a very limited and fragmentary nature, and the 

 list now submitted (with some reluctance) is correspondingly incom- 

 plete. It may, however, serve some purpose as a basis lor future 

 study of our many interesting forms, and, as few lists of Canadian 

 Hemiptera have been published, a record oi the distribution of the 

 species enumerated. When the Abbe Pi:o\ancher was publishing the 

 third volume of his Petite Faune Entomologique du Canada, specimens 

 of ou! Hemi])tera were communicated by .Mr. Fletcher, ]\Ir. Cuignard 

 and the writer, and reference to his work will show that from our 

 material he described several new species, and made a number of 

 additions to his records. 



The appearance of the present list, however, has been possible 

 only through the kindly assistance of Mr Van Duzee, of Baffalo, N.Y., 

 who has examined nearly all the writer's collections, and has also 

 furnished a generic arrangement of the Homoptera, and in other ways 

 given valuable aid. In the Heteroptera the check list of North American 

 species published by Mr. Uhler in 1872 has been followed. 



The following list contains nearly 200 species, buL it only shows 

 how much yet remains to be done before any satisfactory knowledge 

 of our fauna is gained. The references to the relative abundance of the 

 species, and the dates of their appearance, are given from the writer's 

 collection, but in many instances are of small value, as these insects 

 have not been systematically collected, but obtained when the main 

 object of the chase was the capture of Hymenoptera and Coleoptera. 

 The greater part of this collecting has further been in the early summer, 

 when many of the species are immature, and comparatively little in 

 July, August and September, when the mature insects would probablv 

 be most abundant. Our Psyllidse, Aphidse and Coccidce have been 

 omitted, for though the species are numerous and important, espLcially
