berland, and Woodside Moss, CUbiivu, Westmorland; both localities are 

 some miles south of those in which Mr. F. II. Day and otliers have taken 

 tiie species. My friend Mr. K. J. I'earce lia.s also given me, among other 

 Heniiptera, several specimens of Aotouecta halojjhila J. Edw., taken by liim 

 at Minsmere, near Dunwich, on the Suffolk coast. They were fouhd in 

 brackish pools. — G. E. HutchInson, Aystliorpe, Newton Road, Cambriilge ;

The egg-Uiyimj of ^mcjiies. — Referring to the interesting " Notes on Egg- 

 laying of Pteronidea pavida Lep.," by Dr. Chapman, I may siiy that I have 

 bred sawflies for many years and have found that all require food if they are 

 to be kept alive for more than a few days. Most of the smaller species, such 

 as Pteroiiidea, Pacht/ne)nati(s, J^iiiph i/tus, etc., ave quite content if supplied with 

 a few heads of dandelion or butteicup flowers : hemlock or hogweed are also 

 favourites with flies wiiich emerge later in the year. AUantus arcuatus, Ten- 

 thredu livida, and some others kill and eat .small insects and cannot be trusted 

 with sawflies smaller than tliemselves. Pamphilius /(o>'tor»«i is particularly 

 fond of the pcdlen of pine-blossom, and it is well known that sallows in 

 blossom attract many species of sawflies as well as other insects. Abia fa&ciat a 

 has an affection for the flowers of the snowberry. and A. sericea for those of 

 tlie scabious, which are also the food-plants of their larvae. Macrophya 

 punctuin-albuin is the only species known to me which eats leaves of ash, biting 

 holes in them after the manner of certain leaf-eating beetles. I noticed that 

 the leaves which were attacked became much discoloured where the tly had 

 gnawed them. Ash is one of the food-plants of the larva ; I do not know if flies 

 which have been reared on privet would eat those leaves, it would be inter- 

 esting to And out. Arge seems to have a penchant for bramble and wild rose 

 flowers. If fed in this way*and given water daily (for they are very thirsty 

 creatures) sawflies will live for a fortnight or even loi ger, which is useful when 

 one is trying to And out on what plant they will lay their eag^. The longest 

 time I have known one to live is five weeks, the species was M. pimctian- 

 album; she laid her eggs two or three days after emerging, and spent the rest 

 of her life sunning herself and eating and drinking. I have taken several 

 species of Pamphilius at strawberry-blossom, and AUantus vespa on those of 

 Cotoneaster. — (Miss) E. E. Chawner, Forest Bank, Lyndhurst, Hants :

Archisoto)iia besselsi {Pack.) Linmin.on the South Coast of Enyland. — On 

 April 21st, 1919,1 was able to collect a number of these CoUembolans near 

 Beachy Head. They occurred, a few together, on the surface of the water in 

 small rock-pools and amongst the shingle, near the foot of the Head. Wiien 

 the tide rises they apparently seek safety down amongst the shingle itself- 

 Their presence on the South Coast is of particular interest, as the species is 

 one of the Northern and Arctic iorms of CoUembola. It was first described 

 by A. S. Packard (Amer. Nat. 1877) as Isotonia besselsi, and later redescribed by 

 Sir J. Lubbock (Jouru. Linn. Soc, Zool. xxvi, 1898) under the name Isotoma 

 spitzberaenensis. It has previously been recorded in Britain by G. H. Carpenter 

 and W.Evans (Proc. Roy. Soc. Edinb. xiv, 1899) from the Scottish Coast, and by
