The Aphids here recorded include Macro siflmm sonchi, L., taken 

 on Cichorium in August and Centaurea in October ; Myzns cerasi, F., 

 not uncommon on wild cherry in July ; Rhopalosiphum ribis, L., 

 causing twisting and distortion of currant shoots ; Aphis cardui, L., 

 taken on thistle in June ; A. laburni, Kalt., very abundant at the 

 end of June, twisting and stuntmg young shoots of acacia, and also 

 occurring on lucerne ; Crypto si pJium artemisiae, Buckt., taken under 

 the leaves of Artemisia in July ; Dryobius croaticus, Koch, found in 

 July on oak shoots ; Eriosoma {Schizoneura) ulmi, L... common on 

 elm in June ; and Tetra7ieura ulmi, De G., the empty flask-shaped 

 galls of which were found on elms in July.

 a Braeonid. — Entomologist, London, li, no. 665, October 1918. 

 pp. 227-229, 1 fig. 



In the autumn of 1915 the cocoons of an Aphid-destroying Braeonid, 

 probably Praon volucre, Hal., were found in the New Forest to be 

 attacked by a fungus, Isaria arachnophila, hitherto supposed always 

 to infest spiders. This seems to be the first time that an entomogen- 

 ous fungus has been recorded as attacking a Braeonid, though 

 Cordyceps myrmecojihila has been found on an Ichneumonid. 



Scott (H.). Swarming of the Chalcidid, Pterotnalus deplanatv^, Nees, 

 in Buildings. — Entomologists' Mthly. Mag., London, Iv, no. 656, 

 January 1919, pp. 13-16. 



Vast swarms of the Chalcid, Pteromalus deplanatus, Nees, invading 

 houses, have been recorded for three years in succession near 

 Godalming. The invasion begins about the middle of July and lasts, 

 if the weather is seasonable, till about the end of August. 



An explanation of these swarms that has been suggested is that they 

 originate in the buildings where they occur fi'om Anobiid beetles in 

 the woodwork. To this it may be objected that they have been 

 definitely recorded as entering buildings from without and that 

 incredible numbers of Anobiids would have to be present to explain 

 the existence of such myriads of parasites, even if many emerged 

 from a single host. Another, and more probable explanation is the 

 recent extreme abundance of Tortrix viridmm of which P. deplanatus 

 is a parasite.
