24 THE CANADUN ENTOMOLOGIST. 



Listronotus. Of this genus several species occur upon semi-aquatic 

 plants, but it may not be generally known that they appear to be more 

 readily attracted by lights than most rhyncophora. Such I found to be 

 the case one summer, when considerable numbers came to lights placed 

 on a balcony for moths, although the house stood on a hill at some 

 distance from the water (Rideau river). 



Pachylobius picivorus Germ, is quoted by Mr. Beutenmuller (Can. 

 Ent., Vol. XXII., p. 202,) as infesting pine, because in a list of insects 

 found upon that tree (Trans. Ottawa Field Nat. Club, No. 2, p. n,) I 

 mention Hylobius stupidus. The beetles so referred to I have since 

 found to be only somewhat larger specimens of H. pales, which were so 

 labelled in the collection of the late Mr. Billings, and probably in other 

 Canadian collections. While speaking of this genus I may mention that 

 I once found a hibernated specimen of H. cojifusus Kirby whicu had 

 punctured with its beak the tube of a blossom of the Mayflower (Trailing 

 Arbutus, Epigea repens) and was apparently feasting on the nectar 

 therein. I do not recollect the date, but snow was still upon the ground 

 in sheltered spots. 



Tanysphyrus lenmce Fab. is very abundant during the summer upon 

 Lemna, upon the surface of which hundreds may sometimes be seen 

 crawling. I have also obtained many, by sifting, from moss in which 

 they hibernate, and the specimens so obtained are cleaner than those taken 

 in summer, which are frequently encrusted with mud or slime. 



Magdalis. Dr. Hamilton (Can. Ent., Vol. XVIII. , p. 115) separates 

 from M. Lecontei Horn a bluish species from Eastern Pennsylvania 

 and Canada. What appears to be this species is common here upon 

 young pines, especially stunted ones growing in stony or poor ground. 

 Specimens vary considerably in the punctuation of the thorax, and some 

 approach the form with canaliculate thorax, which he mentions as found 

 on spruce. 



Anthono7nus corvulus Lee. is found in profusion upon the flowers of 

 Cornel (Cornus) in May, and is readily recognized by its small size, its 

 apion-like form and shining appearance. It varies slightly in size, but 

 not apparently in other respects. 



Orchestes. The various species of this genus are found, as recorded, 

 upon willows, especially in spring. O. paliicornis Say is always common, 

 and 0. rufipes sometimes so on trees in moist localities. O. niger Horn
