At the present time atalanta larvae in different stages are still 

 to be found in this neighbourhood and probably elsewhere 

 throughout the country.

NOTES ON BRITISH NEUROPTEEA IN 1919. 

 By W. J. Lucas, B.A., F.E.S. 



Alder flies {Sialidce). My first capture of the common 

 species, Sialis lutaria, Linn., was one with damaged wings taken, 

 24 May, on a sports' ground in Kingston-on-Thames. Both 

 sexes were captured at the Mill Pond, Leatherhead. on 31 May. 

 Several Cheshire examples were sent for examination by G. A. 

 Dunlop : — Piuncorn, 19 May ; Stretton Moss, 9 June : Moss 

 side, Acton Grange, 14 June ; Appleton Pieservoir, 24 May. 

 From Stretton Moss on 9 June came also a specimen which I 

 take to be Sialis fidiginosa, Pict. Unfortunately one of the 

 clearest tests failed, the transverse nervure in the sub-costal 

 area being missing in both forewings. 



Snake flies (RapJiidiiche) . Both sexes of Raplddia macidi- 

 collis, Steph. were taken by beating at Boxhill, Surrey, on 

 31 May. R. xantho.^tigma, Schum. was reported (F. W. Fordham) 

 from the Selby District of Yorkshire, in which county it is not 

 an uncommon insect. 



Brown Lace wings (Hemerohiida). An example of Hemero- 

 bius hri.muli, Linn, was obtained by beating oak on 30 Aug., near 

 Highland Water in the New Forest. One, which turned out to be 

 H. orofifpus, Walleng. was taken on the occasion of the S. 

 London Society's Excursion to Boxhill on May 31. On the same 

 occasion two cocoons of the genus Hemerohius, Linn, were 

 obtained. One was constructed in the axil of a twig on a small 

 branch of dead wood, the material being a very thin whitish 

 lace- work of silk within a still finer lace-like web. The inner 

 cocoon was elliptical, about 5 mm. long and about 2'5 mm. wide. 

 From this a somewhat small imago of II. quadi-ij'asciatus, Beuter 

 was bred on the 6th (or 5th) of June. The other cocoon (which 

 was attached to a pine needle), though made of a somewhat 

 open lacework of silk, was less transparent and of a yellower 

 tint. It was elliptical, or perhaps slightly pear-shaped, about 

 7 mm. long and 3*5 mm. wide. It produced an imago of II, 

 concinnus, Steph. on 8 June. In each case the pupa left the 

 cocoon at one end, and was free from it before disclosing the 

 imago. 



GrREEN Lacewings {Chri/sopidcs) . One Chrt/sopa Jiava, Scop. 

 •was found on a tree-trunk at Netley Heath, Surrey, on 5 July 

 (but it was not immaculate on the prothorax). C.prasina, Piamb.
