singly, and he had taken it twice in the White Field. 

 Ennychia octomaculata, Fb., and Etipithecia plumbeolata, Haw., 

 were perhaps the only two other species of any importance. 

 The Rev. E. C. Dobree Fox and the Rev. C. F. Thornewill were 

 also collecting in the neighbourhood at the time with similar 

 experiences to his own ; he, in company with these two 

 gentlemen, twice visited Beachy Head, and they took between 

 them on the first occasion twenty-five, and on the second 

 occasion, twelve specimens only. 



Mr. Carrington stated further that on Beachy Head he 

 noticed the bee orchis {Ophrys apifera, Huds.) in greater pro- 

 fusion than he had ever seen it before ; on getting back to 

 Box Hill on the loth instant he found the species just 

 beginning to come into flower ; it would therefore seem that 

 at Beachy Head it flowered a week earlier than at Box Hill. 



Mr. Billups asked with reference to the habits of the heron 

 whether they flew in flocks or in pairs ; as on the 22nd 

 instant, he saw seven fly over the Borough in the direction 

 of Battersea. 



Mr. C. Fenn said on the Devonshire Moors they could be 

 seen in flocks of twenty or thirty, but about the London 

 district they were generally seen either singly or in pairs. 



Mr. Carrington remarked that in the south of England they 

 generally flew singly ; he had frequently seen single examples 

 cross over Box Hill and Dorking in February and March, 

 and in the marshes below Southend, Essex, they occurred 

 singly. Mr. T. D. A. Cockerell added that in the west of 

 London they passed over singly or in pairs.

Adverting to Colonel Blathwayt's communication to the 

 Entomologisf s Monthly Magazine for the month of April 

 last, p. 109, Mr. Jenner Weir exhibited specimens of the two 

 forms of the Dipteron Volncella botnbylans, L., which 

 mimicked the Hymenopterous Bombus lapidarius, L., and 

 Bombus terrestris, Kirby, respectively; stating that he fully 

 concurred with the Colonel in considering that this remarkable 

 dimorphic condition of the Volucella assisted it to become 

 parasitic upon two species of Bombus differing both in colour 

 and markings, and stated that it was interesting to observe 

 that, notwithstanding the two static conditions of the insect
