Gerris najas, DeG., in the north. — In a small stream in the parish of North 

 Hykeham, Lincolnshire, I came across, on the 6th inst., a pair of Gerris najas, DeG., 

 in cop. This seems to have been taken in extreme southern counties only up to 

 now. — Id. 



Correction respecting Ornix fagivora — On p. 151, line 9 from the bottom, of 

 this Tol., " differ " should read " differs," and refers not to the larva itself but to its 

 way of constructing its domicile. In Stainton's " Nat. Hist, of the Tineina," vol. 

 viii, pi. 3, the larva is represented to the best of my recollection as living in a rolled 

 leaf of beech, those I found here had folded back the edge of the leaf so that the 

 turned down portion rerdained almost flat and fitted closely to the under surface of 

 the leaf ; owing to this the domiciles were very inconspicuous and diiEcult to detect- 

 A larva which I placed on a seedling beech gi'owing in a flowerpot crept on to the 

 upper surface of a leaf to pupate and turned up a little corner of the leaf to con- 

 struct its cocoon in ; acting on this hint I searched the buslies where I had found 

 my larva and got two cocoons spun up in the same fashion near empty domiciles, 

 but I cannot say whether this is their usual way of pupating. — C. E. DiGBY, 

 Sonning : August, 1898. 



[Mr. Stainton says that the leaf has "a piece of the edge turned down and 

 fastened to the under surface ; " but the figure referred to seems to convey the idea 

 of a rolled leaf. — Eds.] 



Psithyrus rupestris, F., var. arenaria, Panz., at Brighton. — Mr. Alfred Brazenor, 

 of 39, Lewes Road, Brighton, has sent for my examination a $ of the above named 

 variety taken on the downs near Brighton. As it is, I believe, of considerable 

 rarity in this country, I think it may be worth recording. F. Smith, in his British 

 Symenoptera, 2nd ed., p. 221, says that the late Mr. Wing had a specimen, and 

 that Mr. Bridgman, of Norwich, had taken specimens near that city. It would be 

 interesting to ascertain whether tlie Bombus lapidarius with which these vai'ieties 

 of P. rupestris associate show any tendency towards a similar coloration of the pro- 

 notal hairs — the variety of lapidarius ( $ and $ ) with the pronotal hairs pale being 

 as rare or rarer in this country than the var. arenaria of rupestris. — Edwaed 

 Saunders, St. Ann's, Woking : August, 1898. 



Crabro gonager, Sfc, at Putney. — I had the opportunity this August of searching 

 for insects in the wood of an Acacia I had cut down in my garden. I found in 

 burrows in the wood Pemphredon lugubris, Crabro leucostomus (abundantly) ; besides 

 one (J and one ? of Crabro gonager, their burrows were stocked with a small green 

 Aphis. There were a great many holes of Anobium in one part of the tree, and in 

 two of these I found the male of Stigmus Solskyi ; here again there were the 

 remains of small green Aphides at the bottom of the burrow. — Haeoid Swalb,
