LIEUT.-COL. S. MONCKTON COPEMAN ON A RARE PLY. 481 



The Giant Centipede is nocturnal in habits, bnt it may some- 

 times be found on the move during t'ae day, and when disturbed 

 its rustling passage through the undergrowth is distinctly 

 audible. Occasionally it is found sheltering in the rock iissures 

 leading to a deep seated Par.isol Ants' nest, and when the latter 

 is attacked with a chemical exterminator the bewildered lodger 

 emerges. 



Lieut.-Col. S. MoNCKTON Copeman, M.D., F.R.S., and Major 

 E. E. AusTEJf, D.S.O., F.Z.S., exhibited, and made remarks upon, 

 photographs and specimens of the rare fly Hylephilas ohtusa Zett. 

 The exhibition included tlie only male of this species captured 

 in this country in the neighbourhood of the burrows of the bee 

 Andrena ftdva, on which the female of this fly is parasitic. The 

 specimen was captured on Pi'imrose Hill, London.
