Slrexjuvencus F. in Yorkshire. — In connection with Mr. Bayford's note on 

 the above (Ent. Mo. Mag. vol. Ivii, p. 277), and the information conveyed that 

 there has only been three previous records from Yorkshire, I am reminded 

 that I have been lacking in not placing on record four specimens I received 

 from Mr. W. Fletcher, of Wakefield, in 1914. I was under the impression 

 they were the commoner S. noctilio F. until I submitted them to the Kev. F. 

 U. ^lorice, when I was pleased to learn they were the rarer S.jiivencus F. —

Le2}:doptera in the Ihlgelley district, Merionetjishire, — While collecting in 

 the valley of the Gwynant, a mountain-torrent which flows tlirough a wooded 

 valley and joins the Mawddach about three miles below Dolgelley, I have 

 been fortunate enough to obtain several Lepidoptera, which I believe have only 

 rarely or never been recorded from this district. I append a list. 



Colias eduaa, one specimen, September 1918 : Vatiessu c-album, often 

 common, sometimes seen in April as well as in September; Ijycaenn phlaeas, 

 var. schmidtii, one specimen, September 1912; Sphinx ligusfri, one larva on a 

 solitary ash-tree on the slopes of Cader Idris ; Stauroj^us fa[/i, two larvae 1917, 

 one imago 1918; Acrojiycta aim, two larvae 1916; Polyploca ridens, larvae 

 often very common, imagines not uncommon ; Ayrotis ashivorthii, one larva 

 1 920 ; Xylvphasia scolopacina, several large specimens were taken at privet- 

 blossom in August 1919 ; Stilbia anomala, common on heathy tracts ; Taenia- 

 cdinpa miniosa, in 1918 this was abundant at sallow-bloom ; Cirrhoedia 

 xerampelina, of regular occurrence ; Lithophane socia, one specimen at 

 sjiUow, April 1920; Mesoleuca ocellata, common; Perizoma hlandiata, one 

 specimen, 1917 — this specimen was captured on the south side of the 

 iMawdd.ich, not near Cwni Bychan, which I believe is a regular locality 

 f.jr it ; Eupitliecia linariata, one specimen ; Eurymene dolnbraria, one specimen 

 bred from a larva found on oak ; Tephrosia cousonaria, occurs regularly ; 

 'Pephrosia pnnctidaria, common every year. 



Since I have only collected in the locality regularly in April, August, and 

 September, this list is necessarily very incomplete, but it may prove of interest

CItloropiscu circumdata My. { = ornata Loeio, nee My.) occurriny in houses. 

 — Dr. Imms's note on p. 20 of this Volume about this species has decided me 

 that I ought to report a similar occurrence here. It was at the beginning of 

 September that I tirst noticed numbers of the flies in the top rooms of this 

 house. They were chiefly in a room which I use for my study, and in a neigh- 

 bouring bedroom, but also in the other rooms on the same floor; and there 

 were none at all in the lower parts of the house. The two rooms where they 

 were chiefly observed had windows facing, those of the bedroom North only, 

 those of the study East and South. The study is a large room, formerly used 

 for billiards, and the flies were in every part of it, but were most numerous on 

 the ceiling in the S.E. corner between the windows. Here they were packed 

 so close together that in a test-case, a narrow-mouthed cyanide bottle of barelv 

 2-iuch inside diameter, placed over as man\' as it would cover in a typical 

 portion of the mass, was found to contain 17 individuals (the sexes were
