COLEOPTERA.

North Italy are well known, and as nothing of special note occurred, I 

 will not dilate on the butterflies, more especially as it is many years 

 since I studied this group, which has now become more than ever a 

 subject of special investigation. My son went partly up one of the 

 mountains and brought back Si/ntowis plieqea and reports of several 

 Zygaenids, so no doubt the upper slopes would be well worth working.

Lepidoptera attacked by Birds. — On August 19th I was given a 

 specimen of the Convolvulus Hawk Moth {Aipiiis conrolvnli) which had 

 been picked up on the bank of the river at Wroxham. It was evidently 

 a freshly emerged specijiien and in fine condition, with the exception 

 that the lower half of the abdomen had been pecked ofl", probably by a 

 bird of some kind. On September 4th I found a pupa of the small 

 Copper butterfly {Ihiiiiicia i)hlaeat<) at New Fen, near Waterbeach. 

 This I took home, and the perfect insect emerged in about a week's 

 time. As the small Copper occurs in my garden I decided to let it go, 

 and put it out of my study window on to the creeper. Next day I 

 observed the four wings of the butterfly on the leads. I generally put 

 bread for birds there ; it is therefore most probable that the insect had 

 been eaten by a bird and its wings allowed to fall on the leads. —

A White-bodied Piekis rapae from Japan. — A form of Pieris 

 rajiae, in which the abdoujen is entirely covered with white has long- 

 been known from Syria under the name of var. lencusonia, Schawerda. 

 From no other part of the world has a similar form of this well 

 known and common butterfly been described, so far as I am aAvare. It 

 was therefore with much interest that I came across an aberrant speci- 

 men of Fieris rapae with white abdomen in a lot of butterflies sent 

 to me some time ago by Mr. S. Satake, of Tokyo, Japan. A brief 

 diagnosis follows : — 



Pieria rapae ab. albiventris, nov. aber. 



Belongs to subsp. cmcivora, Boisd., and is about the same size as 

 the typical form of that subspecies, differing as follows ; — The apical 

 black mark on the upperside of forewing larger at least by one- third, 

 the shape more nearly approaching an equilateral triangle than a 

 scalene triangle ; no trace of the dark suffusion on the underside of 

 hindwings ; abdomen entirely white, as in var. leucoaoina, Schawerda. 

 Much larger in size and by far the more strongly marked than var. 

 leiicdHonia. 



Length of boJy, f inch ; expanse of wings, 2i inches.

Leptura rubra, L., in Norfolk. — On August 6th, 1918, Mr. H. J. 

 Thouless captured a male of Lej)tnra rubra on the wing at Horsford, 

 in Norfolk. Each year since he has taken a small number of speci- 

 mens in this locality, on and in stumps of Scots pine. This year he 

 was kind enough to tell me that he had again found the species, and 

 I determined to go to Norfolk and try for it. On August 18th I visited 

 Horsford and obtained a short series of the beetle, on the stumps and
