There are many remarks to make on it. We notice first of all 

 the increase of Parasitic Hymenoptera, Ants, long and mid-tongued 

 Lepidoptera, long-tongued flies, Coleoptera and miscellaneous insects 

 (chiefly Thrips) to autumn. We notice that mid-tongued Hymen- 

 optera (Andrena, Halictus, Nomada, Chrysis, and Odynerus) are 

 summer insects, as also are the Tenthredinidse, the Wasps, and the 

 short-tongued Lepidoptera (Eriocephala only). The short-tongued 

 flies and the Bombi decrease from spring to summer to increase 

 again in autumn ; while Apis seemed almost to disappear towards 

 autumn. 



Hymenoptera. Apis, a stranger introduced and kept by man in 

 the glens, may be henceforward disregarded. We will turn to the 

 Bombi. The vernal abundance of Bombi is due to B. lapponicus, 

 F., the autumnal to B. terrestris, L., and B. agrortim, F., especially 

 the former. B. agrorum is the longest torlgued of the three, and B. 

 terrestris the shortest ; seasonally they were distributed as follows 

 (the seasons being calculated as of 61 days) :

 B. terrestris ..... 



Short-tongued Flies. Like the Bombi, the short-tongued flies 

 showed a summer decrease. This our largest group in Table V. 

 deserves some subdivision, and on separating the orders we get 

 the following :
