246 CLIMATOLOGY. 



Tabani. In dry seasons rivulets become low, 

 though rivers retain their strength. 



July. Our warmest month. The river unusally gets low. 

 Sturgeon fishing continues. Cattle become lean, 

 being tormented by flies in the day, and feeding in 

 the night only. 10th — 20th. Many genera of Cole- 

 optera appear, some of them of forms more charac- 

 teristic of warmer climes ; Cicindelce, JYecrophori, 

 many Buprestes, and a species allied to Lucanus. 

 Of those whose larvas live on wood, the Serropal- 

 pus, a very fine Dorcacenis, Cerambyx, Callidium, 

 Lamia, and numerous species of Lepturetce. Neu- 

 roptera are abundant on the banks of the river — 

 LibellulcB, Agrion, &c. ; and on the leaves Heme- 

 robius, Panorpes, Sialis. In the other orders, also, 

 there are many genera to keep up the character of 

 the month. It ends with bringing in strawberries, 

 and in sending off sturgeon, which return to the 

 depths. 



Aug. The raspberries begin to ripen. Young ducks are 

 well feathered. We have sultry weather for a few 

 days, and then thunder-storms followed by chilly 

 nights. 10th. Pigeons (Ectopistes migratorius) are 

 numerous. Young geese (Anser canadensis) can 

 fly. Gnats decrease, and sand-flies (Similium) re- 

 place them. 

 15. The raspberries, and red and black currants ripen. 

 Grasshoppers are full grown. Trout move about, 

 ascending the river. Sturgeon are very scarce. 

 Grass becomes brown in dry situations. 20th. The 

 noisy lesser tell-tale ( Totanus flavipes) appears, 

 and if we have much rain we are visited by a 

 species of snipe. The golden and ring-necked 

 plovers are not uncommon. 



Sept. The air is generally cooler and the wind stronger, 

 and frosty nights may be expected.
