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 “took 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, damp nights, are the times that I have been successful, 
beginning about sunset in the 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 Potts. 
Life-history of Acidalia emarginata.—A female, taken 
during the first week in August, last year, deposited a few 
eggs, from which the young larve 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 ; aud 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 8rd 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
