180 THE ENTOMOLOGIST. 



weeks getting the number, the "physical fatigue" was there- 

 fore not so very great: an average of two hundred and fifty 

 specimens a week is surely not very hard work for four 

 enthusiastic collectors! Great pleasure most certainly did 

 come through my success, which enabled me to give some of 

 my friends some very fine series of this insect. I also 

 attempted a little exchanging, but soon found the greatest 

 pleasure was to be obtained in giving them away. As to the 

 man who "look the whole spring-brood" of Sinapis, it is the 

 first I have heard of it. Anyone who could attempt such a 

 mean and selfish action (unless he were a dealer, — it would 

 be pardonable then), should be treated with silent disdain and 

 contempt. — H. Ramsay Cox ; Lyndhurst, June 14, 1875.

 Sugaring for Moths. — I should like to say a word respect- 

 ing sugaring. I have practised that pleasing pastime more 

 than a quarter of a century. I have found that a good deal 

 depends on the atmosphere : the weather gloomy, thick, 

 foggy, daiTfip nights, are the times that I have been successful, 

 beginning about sunset in tlie month of June ; and instead of 

 putting the mixture on about the height of my breast I run 

 the brush right down to the ground. — John Polls. 



Life-history of Acidalia emarginala. — A female, taken 

 during the first week in August, last year, deposited a few 

 eggs, from which the young larvae appeared on the 13th of 

 that month. They grew very slowly until the time for hyber- 

 nation came; and although they fed at intervals throughout 

 the winter they increased very little in size. In March of the 

 present year they began to feed more vigorously ; and have 

 now, July 13th, become about three-quarters of an inch long, 

 after having lived in the larval state exactly eleven months, 

 and spending most of that long period almost stationary on 

 the dead twigs of the food-plant (Galium mollugo), resting 

 sometimes in a straight position, and sometimes — especially 

 in their very young days — with the back arched. Body 

 tapering anteriorly, ribbed transversely and rough to the 

 touch ; the transverse ribs less distinct on the anterior portion 

 of the middle segments. Colour of head and face dark brown. 

 Head notched, and thickly sprinkled with hairs ; as are also 

 the 2nd and 3rd segments, on which the hairs point forward. 

 Colour of body various shades of olive-brown. The medio- 

 dorsal line is composed of two slender, darker lines, edging
