common on Scots pine, as in the Rhine valley, Dauphiny, etc. 

 This is remarkable in so far as that, amongst the forty or fifty 

 species of trees and shrubs on which it grows in England, Scots 

 pine has never been recorded. The plants of mistletoe are usually 

 scattered irregularly over its host, and this is also the case as 

 regards the Scots pine, but I noticed at Bourg d'Oisans that, in no 

 small proportion of cases, it was crowded on the upper six, ten or 

 more feet of the leading shoot, so as more or less completely to 

 smother it. The photographs illustrate this curious distribution. 

 How this occurs is open to discussion ; most probably it has some 

 reference to the perching habits of the birds that happen to be its 

 chief disseminators. (See Plates IX. and X.) 



Mr. A. E. Tonge exhibited slides illustrating the burrows of 

 .Ef/eria andrenaformh, a wild, newly-emerged A. form iac for mis and

 buckthorn, a web of Eriogaster lanestris on sloe, the ova of ISlon- 

 agria nenrica on the inside of a sheath of reed-stem, a batch of the 

 ova of Tccuiocampa gothica on a head of bramble, a cocoon of the 

 niicro-lepidopteron, Lyonetia clerckella, and of the ova of several 

 species of Lepidoptera, in sitfi, wild laid. 



Mr. C. B. Williams exhibited slides illustrating the oothecfe of 

 Manti!< bioculata, a mass of micro-organisms obtained by the use of 

 the Berlese apparatus, the egg of the snake-fly (H/iajihidia maculi- 

 collis), several species of Conioptenjx and a species of Aleurodidte. 



Mr. West (of Ashtead) exhibited slides illustrating various species 

 of springtails (Collembola), the crustacean which inhabits ants- 

 nests {Platgarthriis liofmann^eggii), ova of Plnjlloxera punctata, 

 several species of freshwater Rotifera and Entomostraca, and 

 examples of Mycetozoa. 



Mr. Dennis exhibited slides illustrating galls on willow catkins 

 and leaves, lime (an unnamed species of Diptera), ash, aspen, drop- 

 wort, plantain, honeysuckle (aphis), fir (aphis), alder (mite), walnut,

Mr. Colthrup exhibited a long series of slides illustrating the
