rough ground a little further inland must now be examined, when the 

 larva of A. zephymna will be found inside near the surface of the earth. 

 Distributed about on the broken ground of landslips or ledges of the 

 cliffs, will be found many old roots of the knapweed (Centaurea nigra). 

 We must examine some of them, and shall no doubt soon be rewarded 

 by finding the larva of X. zcegana. In breeding this species, we are 

 pretty sure to have some fine dark specimens emerge. 



The above are a few of the species that may occupy some of our 

 spare time during the winter months. We should at the same time 

 keep a good look out for any local plants that are likely to contain 

 larvae, for we may, by doing so, unexpectedly breed a new species, 

 or one whose early stages are at present unknown. Now just a word 

 as to rearing the larvae from the roots we have obtained. Get any 

 medium sized boxes without lids, about twelve inches deep, and put 

 a layer of earth about two inches deep at the bottom, sort out the 

 roots, keeping only one sort in each box, and then place them side by 

 side as close as possible, till the bottom is covered all over, then 

 sprinkle earth all over till the roots only are covered, the stems 

 remaining above the surface and shake well down to fill up the 

 interstices and place out in the open air, leavmg them exposed to all 

 weathers till near the time of emergence, no more attention is required, 

 and there is very little doubt but that at the end of the following 

 season we shall be fairly well pleased with the result.

CELCENA HAWORTHII, 



[Read before the Lancashire and Cheshire Entomological Society, October 12th, 1S91) 



BY C. E. STOTT. 



My first experience with the subject of to-night's paper goes back 

 to the time when I commenced to study the order Lepidoptera; and I 

 can well remember when my two elder brothers returned from a day's 

 shooting on the moors, bringing with them a dozen or more specimens 

 of this insect; and, above all, I can well recollect the zeal with which 

 I pored through "Newman's" pages, and the pride with I finally 

 determined them to be Haworthii. I truly believe those specimens 

 were, to me, more valued than my two brothers' "bags" put together.
