The pi'etty little Tnrtrix pronuhana, of which the second 

 emergence usually takes place about the beginning of September, 

 appeared to be practically over early in August, but stragglers 

 met with during the latter part of September appeared to indicate a 

 partial third generation. A single specimen of Tnrtrix podana that 

 emerged on September 13th from a pupa found in a shoot of 

 FJuonijmus japonica, was clearly a case of a second brood, a 

 circumstance that was thought to be verj- unusual in this species. 

 Teras contaminaiia was common among the blackthorns during the 

 latter half of September,' showing no great variance from the 

 usual time of appearance of the species. 



Mr. B. Harold Smith said that his holiday had been spent in 

 South Cornwall near the Lizard, between September 4th and 25th. 

 The weather was very fine during the first fortnight, but the last 

 week was rainy with high winds, so that during that part of the 

 time comparatively little collecting could be done. His experience 

 in regard to Pieris brassicce was at variance with that of Mr. Adkin 

 at Eastbourne, for in Cornwall he had found it very abundant, and 

 at night numbers were to be found at rest on a species of 

 Meaenibry anthem H)n . P. rapa; and P. napi also were very common, 

 but less so than the first named species. Colias ednsa was met 

 with very sparingly, about six examples in all being seen. One 

 female that was taken deposited a number of eggs which 

 commenced to hatch about October 3rd, and were not all out till 

 the 11th. Rumicia p/dceas swarmed everywhere, and included a 

 number of the var. caruleopunctata. One female was taken in 

 which the right forewing was of the var. schmidtii form, fading 

 away to almost white at the outer margin. Pyrantels atalanta was 

 very plentiful, and P. cardin fairly so, but Aylais urtica- was 

 distinctly scarce. Pararyc uieij(rra also was very plentiful. 



Agrius (Sphinx) convolriiU was not uncommon, and two each 

 Mandiica I Acherontia) atropos and Phrijxtis [Deilcphila) livornica 

 w^ere taken at light, a larva of the latter species also was found 

 which selected sallow as its food from among a number of plants 

 with which it was supplied. Se.sia {Macroiilosaa) stellatarnm was 

 abundant, and on two occasions was noted on the wing well after 

 half past six in the evening, once when it was quite dark, with 

 high wind and squalls of rain and fog. 



Geometras as a rule were scarce, but a couple of specimens of 

 Sterrha aacraria were taken, one, a female, on the wnng, by Mr. 

 Smith, the other, a male, flying over coarse grass, by a friend who 

 was with him. Acidalia niaryitiepnnctata {proniiitata) occurred 

 fairly commonly on the sugar patches.
