that the elytra are half orange and half black, or very deep 

 blue. As in this case, they are deeply fuiTowed, and the 

 hind wings are smoky black (Lycus Terminalis). 



C. — As I was roaming on the bank of the river yester- 

 day, near the bridge, I caught a large black HemerobiuSj 



the wings banded and spotted with white (Hermes f ) 



Great numbers of Dragon-flies were flying over the water, 

 many of them in coitu, in the form of a circle, having a very 

 singular appearance. Towards evening, I noticed several 

 Day-flies ( Ephemera J^ dancing in the air above the river. 

 I observed that they alternately fluttered perpendicularly 

 upwards for about ten feet, and then sunk down with 

 closed erect wings; the anal bristles held perpendicularly 

 and diverging : then they would flutter up and sink 

 again ; continuing these motions over one spot, till I left 

 them. 



F. — The Brush-footed Bee (Megachile Willughhiella ) and 

 the Green and crimson Elater, (Elater Metallicus ? J both 

 natives of Newfoundland, I have observed here lately. — 

 There are not nearly so many species of insects common to 

 that country and this, as I should have expected from their 

 proximity. It is stated by Linnaeus, if I mistake not, that 

 twelve degrees of latitude make almost a total change in the 

 insect species ; but probably much difference is also caused 

 by the situation of a country : for instance, between the coasts 

 of an island, as Newfoundland, and an inland region, as this 

 part of Canada. 



C. — A lad gave me, yesterday, a Water-fly of very large 

 dimensions, measuring about three inches and three-fourths 

 in spread of wing. It is of a dusky colour, and the nervures 

 of the wings are of the same ; its claims to notice are only 

 its enormous size, as compared with other species of the 

 genus, for it has no beauty. It is Vteronarcys Regalis.
