THE ENTOMOLOGIST. 197 



the winter months, but have never found a living pupa : I am 

 therefore of opinion that bees can only survive the severity of 

 our winter months in the larval and perfect state. 



I am not aware of any addition having been made to the 

 number of species of our native ants, but I have this year 

 (186{)) found Formica aliena very plentiful on the sand-hills 

 at Deal ; and Mr. Bold has taken the rare Myrmica lobi- 

 cornis near Newcastle. Dr. Sharp has taken workers of 

 Myrmedonia Latreillii in Headly Lane, at Mickleham, where, 

 he informs m&, the species is tolerably abundant in moss and 

 low herbage. Ammophila lutaria has been more numerous 

 at Deal than I ever before observed it, whilst the two other 

 native species, usually very abundant there, were compa- 

 ratively rare : for the first time I detected A. lutaria with its 

 prey, the larva of some species of Noctua. 



I have scarcely seen any wasps during the season, and Mr. 

 Bold informs me he has only noticed three workers in the 

 north. 



The pretty little Ceratina caerulea has been plentiful in the 

 "Warren at Folkstone during the months of July and August : 

 this little bee is usually considered a rarity ; it is certainly 

 very local ; 1 once found it as near London as Charlton, in 

 Kent: I have captured it as late in the season as the 3rd of 

 October, reposing in the flowers of a species of hawk-weed ; 

 it is more frequently attracted by the flowers of Echium vul- 

 gare, but it also not uncommonly selects those of the com- 

 mon bramble. During my visit to Folkstone in October last, 

 I collected a bundle of perforated bramble-sticks, and 1 find 

 on examination that they contain the Ceratina in its perfect 

 condition : the cells are merely separated by a thin partition, 

 I think composed of the pith of the bramble-sticks, the tun- 

 nel being thinly coated with some glutinous secretion adapt- 

 ing it for containing the semi-liquid honey stored up by the 

 bee. I am therefore of opinion that Ceratina always passes 

 the winter months in the perfect condition : Dr. Thwaites 

 has a memorandum in his private journal, " Found perfect 

 examples of Ceratina in bramble-sticks at Stapleton." 



On the 19th of October, so fine was the day, and so greatly 

 had many species of Apidaj been retarded in their labours by 

 the previous unfavourable weather, that I took the following 

 species of Andrenidu; on the wing: — Sphccodes gibbus.
