tilus paluchiin was to be found if one searched for it. The perusal of Dr. 

 Chapman's most interesting paper on the life-history of this species, published 

 in the Trans. Ent. Soc. Lond., 1906, pp. 133 — 154, confirmed ns in oiir desire to 

 find this rare Plnme-moth. Owing* to onr absence from Woking we were tinable 

 to look for it imtil tlie middle of August, but onr first visit on the 21st of that 

 month, to a locality which appeared to us by far the most likely of those round 

 about, was amply rewarded by the capture of a fair number of specimens. We 

 went to the same place several times subseqiiently and found that tlie insect 

 did not begin to fly freely until about 6 p.m., althoiigh it could be disturbed 

 (earlier with difficulty, however), from the Spliagnutn, Narthecium, Calluna and 

 grasses, amongst which most of the Drosera was growing and the imagines had 

 been taken ; it was most abundant about 6.30 p.m. A carefid examination of 

 plants of Drosera rotundifolia yielded, in several cases, obvious signs of the 

 presence of the larvae earlier in the year, but no traces could be seen on D. 

 longifolia, which was also not uncommon, possibly becaiise the latter is a plant 

 miich more difficult to examine than its ally. It may further be noted that 

 practically all the imagines taken were flying over groimd which is so sodden 

 with water during the greater part of the year as to be impassable, althoiigh 

 the Drosera plants are kept from being submerged by the S'phagnum ai-ound 

 them. The plants whose leaves were found to have been partially devoured 

 were, however, all on the wet bare patches where sods had been cut. Searching 

 in similar places not far distant — even 100 yards away — from the spot alluded 

 to above, failed to produce a single specimen. — H. G . Champion, Heatherside,

Oviposition of Baccha. — I am indebted to Miss Alderson for calling attention 

 (p. 217, ante) to my badly expressed final line (p. 193, ante), wliich shoiild read 

 "It is satisfactory to have ascertained an (not the) actual species of Ajihis 

 attacked by it." I by no means wislied to convey the idea that Baccha, confined 

 its attacks to Ajjhis pruni. In tA\e preceding line road " 1900 " for " 1909." —
