112 THE entomologist's RECORD. 



examples, and I do not think I have met with it at large before the 

 beginning of July ; and even in breeding, one does not ordinarily 

 obtain them till about the middle of June — 1893 being an abnormal 

 season. In the Knt. Mo. Mk;/., vol. ii., pp. 90-91 (1865), Dr. Jordan 

 recorded that in Devonshire (Dartmoor, etc.) the imagines from the 

 bilberry- fed larva appear a month earlier than those from sallow and 

 nut, namely, from the beginning of June. Mr. Porritt tells me that 

 this is certainly not the case in Yorkshire, where both forms appear 

 together in July and early August. Dr. Jordan, in this same note, 

 says that he can detect no difference, either larval or imaginal, between 

 the bilberry and sallow forms. I am not aware that any writer has 

 noticed any difference in the larval stage, but certainly the imaginal 

 (as already remarked) shows very decided differences in many localities. 

 As a set-off against these early records of Dr. Jordan's (from the 

 beginning of June), I quote the following instance of late emergence 

 from some brief notes by J. Sparre Schneider, on the entomology of 

 Arctic Norway {Ent. Tidskr., vi., p. 151) : — " In 1881, I found a pupa 

 under a stone, 11th September (!), from Avhich the moth emerged the 

 day after, a small and dark, but well developed, $ ." It is to me not 

 conceivable that this species should throAV even an occasional speci- 

 men of a second brood ; and I look upon all late dates as instances of 

 retardation, probably in the time of hatching, or in the rate of progress 

 in the larva, but possibly occasionally also in the development or dis- 

 closure of the imago. 



As to the resting habits, etc., they probably vary a good deal in 

 the different races. In districts where I have collected, tliey generally 

 resort to the cover of hedges or bushes. They may be readily disturbed 

 by day by the beating stick, often in great abundance. Like nearly 

 all Geometers, they fly freely at dusk, and they frequently visit 

 flowers, if not also sugared trees. As far as 1 remember, I have 

 noticed them chiefly at flowers of Kupatnrlwn cannabinuiii. 



Notes on the Larva of Saturnia pyri. 



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

 Larva of Saturnia pyri. — The larva is of a lovely pea-green 

 colour, rather darker in colour between the sub-spiracular flange and 

 supra-spiracular tubercles ; paler (tending towards whitish) between 

 the two rows of dorsal tubercles ; a faint and indistinct medio-dorsal 

 line can be discerned on some of the abdominal segments. The head 

 is comparatively small, rounded in shape, but tending towards a 

 trapezoidal form, and slightly notched on the crown ; the surface is 

 smooth ; the colour green, with a dark red isosceles triangle in the 

 centre of the face, the base of which runs along the upper edge of 

 the mouth, the apex of triangle not quite reaching the furrow dividing 

 the apex of the head ; the mouth parts are reddish-brown. The 

 head is retractile within the pro-thorax, the cheeks with a few dark 

 hairs. The upper edge of mouth with a fringe of long whitish hairs. 

 The thoracic segments are deeply cut, and the pro- and meso-thorax 

 are partially retractile. The juv-tltora.r, with two turquoise blue pre- 

 spiracular tubercles elevated on stalks, with seven points round the 

 edge, bearing black hairs, and two central black points also bearing 

 long spatulate hairs. Two compound, similarly coloured, dorsal
