Odonata and Lepidoptera at Watford, Herts. — During a stay at 

 Watford in the first half of August, I observed the following dragon- 

 flies in the neighbourhood : — JE>^i-hna f/raiidis, two ; one in Cassiobury 

 Park, and the other a few miles off. .E. rt/anra, one, near Watford. 

 Siimpctniiii stri()latt())i — nih/ata, two, near Tring. I had never seen 

 Liicana cori/ddti on the wing, and Mr. Arthur Cottam, of Watford, very 

 kindly introduced me to thousands of the butterfly near Tring, on Aug. 

 8th. Another butterfly I had never seen before alive was Hesperia 

 comina, flying commonly enough with L. rori/don, L. agcsth, and 

 Ij. alexia. Other Lepidoptera on the same habitat were (Tonnptcri/x 

 rJiawni (one, just out), EnhoUa hipiinrtan'a, and a specimen of Zi/ifccna 

 I'dipi'iuhiUe, which is an intergrade form midway between the type and 

 the variety ceriniis (Robson) with pale yellow spots and secondaries. 

 It was as follows — Primaries : basal spots normal in colour ; succeed- 

 ing spots gradually paler until terminating with the marginal one pale 

 yellow. Secondaries normal. Other butterflies I noticed in the Wat- 

 ford district were Vanessa atalanta, one. It seems as if it were not 

 going to be an atahoita year, though I believe the species is not so 

 common here as at Chester. Thcda ir-alhinn, several individual speci- 

 mens near Watford, and one in the town itself, L.anjiohis (getting over), 

 Epinephelc ianira, Folj/oinuiatiis p/ilceas, ('cEnoniimpha pawphihis (not so 

 large or so bright in colour as our Delaraere and North Wales speci- 

 mens), and a few final examples of E. titJinnns. I kept a sharp look-out 

 for ('alias ((lasa and ( '. hj/ale, but saw neither. Common "whites," 

 probably all or chiefly Picris rapce, were plentiful through the district. 

 The weather all along was very warm and sunny until the 1-ith, when 

 it broke up with copious showers. — J. Arkle ; Chester. 



Notes on Lepidoptera for September, 190L — The second brood 

 of Hmeiinthns popnii larvte, which, as I previously mentioned (ante, 

 p. 258), emerged from the ova on August 5th, have fed up very slowly, 

 and at the time of writing, out of thirty that I kept (having given 

 away the remainder), only seven have yet pupated. The first brood 

 not only fed up much more quickly, but also seemed more brisk and 

 lively : is the difference owing to the change in temperature ? A brood 

 of Ampliidasjis hctidaria, from ova laid by a black female, have success- 

 fully come through, but, curiously enough, one solitary larva, though 

 apparently full-grown like the rest, went on eating for twenty-four 

 days after the others had gone down to pupate, and it was only on 

 Sept. 21st that he disappeared. On Sept. ith I took a specimen of 

 Epinephelc ianira with a large patch of white on the left upper wing. 

 It is not in perfect condition unfortunately, but it is good enough to 

 set. It is a male, and the white patch is about the size of that on the 

 right upper wing of the variety figured in Newman's ' British Butter- 

 flies.' The other three wings are, however, perfectly normal. — F. A. 

 Oldaker ; Parsonage House, Dorking, Sept. 23rd, 1901. 



Lepidoptera at Farnborough, Kent, and Neighbourhood. — Com- 

 pared with last year, this season's collecting is almost nil. All 

 through the summer " sugar" seems to have had no attraction what- 

 ever. Some evenings, in fact, with every appearance of being most 

 favourable, have produced nothing. Last night (Sept. 23rd) I sugared 

 about fifty trees, &c., and examined them all five or six times, the net
