204 THE CANADIAN ENTOMOLOGIST. 



fluid which stains the skin, has a pungent odour, and turns alcohol to a 

 crimson colour. The heads and legs of some worker termites dropped 

 in the same alcohol became of a deep violet colour, but the heads of 

 soldier termites, from their harder integument, remained unstained. 

 These beetles exhibited considerable variation in the disposition of the 

 black markings on their orange-red elytra. I could find no communica- 

 tion with their galleries from the outside. Their social hibernation is 

 interesting. 



Synchroa punctata, Newm. — Beetles and pupae under bark of linden 

 and elm logs (May). 



Attelabus analis,' Illig., bipustulatus, F., rhois, Boh. — On leaves of 

 young hickory. 



Magdalis artnicollis, Say. — On elm foliage (June). 



Anthonomus cratcegi, Wish. — On beech foliage. 



Mononychus vulpeculus, F. — On wicch hazel (June). 



"Cceliodes acep/ia/us, Say. — On witch hazel (June). 



Balaninus nasicus, Say, rectus, Say. — Very numerous under an isolated 

 red oak (Sept. 15 to 22 only), 



Eupsalis minuta, Drury. — In dead oak and linden. 



Cossonus p/ata/ea, Say. — Fifty-four taken under bark of an old butter- 

 nut log (May). 



Determinations of above coleoptera were made by Dr. Horn and Mr. 

 Schwarz. 



Lepidoptera. — A sesiid (Sannina, sp.?) was bred from large knotty 

 galls common on trunks of red oaks. These are rough excrescences of 

 the bark and wood, frequently attaining a diameter of several feet. The 

 moths are about the size of 6". acemi. 



Diptera. — The pine-cone gall of Cecid. s.-strobiloides, O. S., occurs 

 commonly on Salix cordata (June, July). It remains conspicuous 

 through the winter, when these shrubs are otherwise bare.
