segment with four, fourth to eleventh segments with five, trans- 

 verse folds ; the posterior three of each more swollen ; black 

 dots (larger on fourth fold of each segment) on subdorsal line, 

 with slight surrounding tawny tinge. Size, 51-GO mm. 



Change for spinning, June 1st to July 2nd. Ground colour 

 general greyish-blue tinge, shading to green at the head, with 

 tawny suffusion below subdorsal, and two double orange spots on 

 each segment ; dorsal line blue, subdorsal orange. This period 

 lasted from four to seven or more days, after which the larvae 

 spun a very opaque cocoon, varying in colour from a dirty yellow 

 to a very dark brown, according to the character of its surround- 

 ings. 



It will be noticed that the length of each stadium varied 

 considerably in different individuals, so that some larvae pupated 

 in at most seventy-five days, whilst others took at least ninety, 

 although they all received exactly the same treatment. 



The imagines, the first of which appeared on Nov. 1st, seem, 

 so far as they have yet emerged, to be of a ruddier tinge than the 

 majority of those captured. I have secured a number of fertile 

 ova from several parents, and- shall be interested in seeing 

 whether this trait will be accentuated in their progeny if fed on 

 apple, and whether it will disappear if some other food-plant is 

 adopted.

DICYCLA 00 IN HUNTINGDONSHIRE, 1902. 

 By G. Lissant Cox. 



During the "Long" this summer I was very successful in 

 getting round our Dean for several "week-end" exeats, and in 

 company with my friend Mr. H. S. Dickson made some delight- 

 ful flying visits to many places near Cambridge. 



I have been interested to see several notes on Dicycla oo in 

 the ' Entomologist ' for October and November, and perhaps our 

 experiences with this insect in Huntingdonshire may be of some 

 interest. 



On the evening of the 13th of July, when we were bicycling 

 to our headquarters for the night, for some unaccountable whim 

 I dismounted and sugared a noble oak — an old friend — and then 

 went on to our destination. We came past the tree at 2 a.m. 

 on our way home, and I boxed an unknown insect, which, except 

 for the inevitable Xi/lophasia monogliipJia (poli/dou), was the sole 

 specimen at the treacle. That we should have taken it at such 

 an hour was, as future events proved, an extraordinary piece of 

 good fortune. We showed our captures to Mr. W. Farren, and 

 he was not long in spotting the single D. oo, a male in perfect
