174 THE entomologist's record. 



body above appeared to be divided along its axis in two parts, belong- 

 ing to the respective sexes ; on the right side the thorax and abdomen 

 are covered with the greenish villosity characteristic of the S » on the 

 left the thorax is brownish and the abdomen almost glabrous, blackish, 

 with each segment bordered with a pale line as in the $ . Also a 

 series of P. apollo captured at Eclepens in July, 1907, of a beautiful 

 ivory-white, the $ s frequently with the black spots of the forewings 

 marked with red ( = ab. psendononiion) also the two anal spots ( = ab. 

 decora). Fruhstorfer has compared the ivory colour of these with the 

 form iiiellirnlus. from Bavaria. 



Mr. Culot exhibited fine bred exotic Attacids. Mr. Mazel, exotic 

 Sphingids, Nymphalids, and Chalcosiids. Mr. Helle, African lepidop- 

 tera. Mr. Lacreuze, Swiss lepidoptera, including Farnassius apollo ab. 

 riifa from Gex, and a ? Polyoniuiatiis icariis, with triangular black 

 streaks resting on the inside of the orange lunulas and pointing 

 towards the base of the wing. 



The larval habits of Adkinia graphodactyla var. pneunionanthes 

 in spring, just previous to pupation. 



By J. W. TUTT, P.E.S. 

 The light that Dr. Chapman was able to shed on the habits of the 

 spring brood of the larva of Adkinia graphodactyla var. pneumunanthes, 

 detailed at length in The Nat. Hist. British Lepidoptera, v., pp. 524-5, 

 left it quite clear that many of the notes recorded by Freyer, Frey, and 

 Zeller only doubtfully belonged to this species, and, at the same time, 

 left no uncertainty as to the hybernating habit of the larva in the root 

 (or shoots immediately springing therefrom) of Gentiana pnemnonanthe. 

 It left involved, however, the whereabouts of the spring larva, and its 

 habit after hybernation was over. I, therefore, urged Mr. Gillmer to 

 get me, if possible, some plants of Gentiana pnetononantJie, and this he 

 did, and, on May 12th I received some plants from him, carefully 

 packed, and which I was instructed to pot as soon as received. This 

 I did, and the plants seemed to thrive up to a point, though not alto- 

 gether happy. It was evident that the central portions of the plants 

 were much eaten, but a series of side shoots were making fair progress. 

 As, however, I wanted to know what the larvae would do, I did not 

 disturb them much. They made no real external sign until about the 

 22nd, when a fine green larva was seen, evidently nearly fuUfed. 

 The central area of the plant on the ground level was now seen to be 

 somewhat brown and discoloured, but the larva left the plant on which 

 it had been feeding, settled down on a grass-stem some four inches 

 above the ground, and soon its swollen thorax and outstanding (appar- 

 ently knobbed) setjE gave indication that pupation would soon take 

 place ; this happened on the 24th, by which time another larva on 

 another plant was observed ; this also selected a grass-stem on which 

 to spin up, and on the 27th this was also showing the usual modifica- 

 tion observed in shape, etc., in the quiescent stage preceding pupation, 

 and on the 28th had pupated ; a larva also was apparent on the last 

 (third) plant, and as this was already fixed on a grass-stem and near- 

 ing pupation, it is evident that it had been overlooked the preceding 

 day. On the evening of the 28th, two more larvas were observed on 

 this plant both settled on grass-culms, but with the thoracic areas not 

 yet swollen, so that there could be no doubt that it was the habit of
