The oak is also attacked by many species of hymenopterous gall-flies, which distort 

 and disfigure the twigs, buds and leaves, forming swellings and protuberances of various 

 shapes and sizes. The flies which produce these galls are very small, and are generally of 

 a black color, with red or yellow legs.

 Horse-flies (Tabanid.e). 



Kirliy and Spence, in Letter V. of their very interesting Introduction to Entomology, 

 speaking of the Tabanidse say : — " In North America vast clouds of different species — so 

 abundant as to obscure every distant object, and so severe in their bite as to merit the 

 appellation of burning Ilies — cover and torment the horses to such a degree as to excite 

 compassion even in the hearts of the pack-horsemen. Some of them are nearly as big as 

 humble-bees ; and when they pierce the skin and veins of the unhappy beast make so 

 large an orifice that, besides what they suck, the blood flows down its neck, sides and 

 shoulders till, to use Bartram's expression, " they are all in a gore of blood." Packard in 

 his valuable Guide t<> the Study of Insects, page 394, confirms this statement, saying of 

 Tabanua limeolo, "This fly is our most common species, thousands of them appearing 

 during the hotter parts of the summer, when the sun is shining on our marshes and 



rn prairies ; horses and cattle are sometimes worried to death by their harrassing 



Upwards of eighty species of the genus Tabanus are found in North America, and 

 the names of thirty-two of these are on the Toronto Natural History Society's list. The
