Calosoma frigidum. A specimen of this beetle was taken on 

 Kettle Island on 19tli May. C calidum is common here, but no othei' 

 specimen oi frigidum has come under our notice. Many other species 

 of Carabida3 were taken on the same date. Blplotaxis tristls. On the 

 occasion of the Club Excursion to King's Mountain on the 24th May, 

 this beetle was very abundant under and on the pines near which the 

 members lunched. Hojilia tr'ifasciata was at the same time somewhat 

 numerous on the flowers of Viburnun lantinoides and the catkins of 

 willows. Phymatodes thoracicus. During the early part of June, Mr. 

 Fletcher obtained a number of these interesting longicorns which had bred 

 in an old wine cask then used by him as a water-ban-el. Toxotus 

 vittiger. This beetle was captured at Casselman at the Club Excursion 

 of 23rd June. Among other interesting species taken on the same 

 day were Elaphrus cicatricosus, Languria inornata (var. gracilis) 

 Aphodius hyperhoreus, Leptura subhamata, (on oak) Disonycha carolin- 

 iana, (on Rumex salicifolius) Silpha i7icequcde and Psephenus Lecontei, 

 all aditions to list. Purpuricenus humeralis. A fine male of this 

 handsome beetle was taken near Rideau Hall on 27th June, and a 

 female was found upon the sidewalk on Sparks Street, about a fortnight 

 later. This species occurs in the middle and western States, and 

 although recorded from Canada we have been unable to find where it 

 was captured. 



Tanysphyrus lemna', Fab. Immense numbers of this minute 

 weevil were observed on 26th July upon the corre=!pondingly minute 

 water-plant Lemna minor, by which the surface of the brook flowing 

 from Fairy Lake was entirely covered. On the same day the voracious 

 blister-beetle Macrobasis unicolor, Kirby, was seen in destructive 

 abundance on meadow-rue [TJialictrum Cornuti). Stenotrachelus 

 drctatus, Say, was unusually numerous during October, and occurred 

 until the middle of November. Phyllobrotica decorata, Say, was taken 

 during July, at the Mer Bleue and along the Canal, feeding in large 

 numbi'rs upon Scutellaria laterijlora. Among injurious beetles which 

 were destructive during the summer may be specially mentioned 

 Diahrotica vittata, Fab., greatly infesting cucumbers, and Crepidodera 

 cucumeris, Harris, and Phyllolreta viltata, Fab., which did great 

 damage to all garden crucifers, such as cress, radishes, etc.
