would seem to be generally double-brooded here, the first brood 

 appearmg in April and May, and the second in July and August. 

 The larvae resulting from the second brood, as a rule, remain in 

 their cocoons until the following spring, when they pupate some 

 fortnight or so before the imagines emerge. During last Octo- 

 ber, however, numbers of the imagines of both sexes might be 

 beaten from Piniis sylvestris, even up to the end of the month. 



In August Mr. W. J. Lucas was fortunate enough to capture 

 several male and female specimens of the rare dragonfly, Sym- 

 petrum fonscolomhii. 



That weird-looking " beastie," Centrotiis cornutus, turned up 

 in greater numbers than I have ever known before, Cixius 

 2nlosus being also very common. The Typhlocybse were not 

 nearly so abundant as in 1910. Undoubtedly, the insects that 

 were more noticed than any others in 1911 were the common 

 wasps, Vespa vulgaris and V. germanica, which literally swarmed. 

 A worker was observed on the wing as late as November 19th, 

 while a queen, which had flown into a neighbouring cottage, was 

 brought to me on December 30th. This abundance seems 

 rather remarkable, as 1910 was particularly noticeable for the 

 scarcity of wasps here, as in other places.
