spot ; I also took a large $ at Slivno, 27nim. in expanse, with uni- 

 colorous dark upperside, and the underside also as in coretas. Probably 

 similar examples, recorded as coretas, occur." He further notes {Lep. 

 Balkans, pt. 2, p. 181) that, in Bosnia and Hercegovina, the spring form 

 pohjspercluin has been recorded only from Dervent ; but that, at Jaice, 

 specimens of the summer brood with green-blue upperside in g s, and 

 without reddish-yellow marginal spots on the underside of the hind- 

 wing, which Staudinger named dccolorata, have been taken. Aigner- 

 Abafi observes [in lift.) that, "in both broods, the ab. decohrata, 

 Staudinger, occurs at Budapest, Szaar, and Lipik, the 3 often with a 

 broad marginal band; the ? without blue dusting." Hormuzaki 

 reports it from Bucovina. 



Jlg^OTES ON COLLECTING, Etc. 



KuMiciA PHL^AS IN OcTOBER. — I captured a J of 7i'. jMaean that 

 was observed near here (Brasted), flying in the the hot sunshine, on 

 October 28th. Its appearance so late was the more striking, as snow had 

 fallen on the previous night and was still lying in shekered places. —

:iaOTES ON LIFE-HISTORIES, LARY^, &c. 



Aberration of larva of Papilio machaon. — I may note that I 

 obtained seven more melanic larvae of Papiliu )iiachaon similar to those 

 already noted {antea, p. 240). I had hoped to have reared the imagines 

 to see if they would differ from the type, but a mouse got at the pup^ 

 and ate every one. — P. A. H. Muschamp, F.E.S., Staefa, Zuricher-See.

Notes on Argynnis aglaia. — On June 2nd, I received a larva of the 

 above, in its last skin, from Dr. Chapman, who found it near Bude. 

 In appearance it was a much duller object than that figured in 

 Buckler's " Larv^," lacking the yellowish dorsal stripes entirely, the 

 lateral red spots being, also, smaller and less brilliant than those in 

 the figure referred to. Both ]'iola sylvatica and V. odorata leaves, 

 with which the larva was provided, were eaten ; there were no regular 

 times of feeding, but, between its meals, it invariably retired to the 

 bottom of its cage. On the least disturbance the larva ceased to feed, 

 for the time being, and, when its cage was moved for changing the 

 food, etc., would jerk or twitch its entire body rather violently. 

 Becoming restless, on June 13th, it appeared to fail to find a suitable 

 place for suspension, and finally pupated, without any attachment, on 

 the floor of its cage. The pupa much resembles that figured by 

 Buckler, but the " two rows of blunt, conical, projecting points" are 

 far less conspicuous, and the last segments are bent completely round, 

 so that the cremastral area all but touches the tip of the wing-cases, 

 The resulting butterfly, a male, was disclosed on July 9th. — R. M. 

 Priweaux, F.E.S., Brasted Chart, Kent. October 28th, 1908. 



On the muscular force possessed by the larva of Cossus lig- 

 nipekda. — Recently one of my boys brought me a full-grown larva of 

 the above. After giving a brief account of its habits, etc., I placed it 

 for the time being in a small chalk box, such as is used for school 

 purposes, and left the lid apart about one-sixteenth of an inch. I 

 placed on the lid a series of weights represent 1850 grammes. Shortly
