are pale in colour, black at the summit. Hairs pellucid, club-shaped, 

 especially on second segment, where they are considerably longer than on 

 the other segments. 



Tried the larvae with Vaccinium, two or three species of birch, two or 

 three species of willow, Amphicarpsea Monoica, Epilobium Augusti- 

 folium, and several other plants at a venture, but in all cases they crawled 

 off the leaves on to the side of the jar. One that was afterwards placed 

 upon a willow leaf just died and dried up where it was put. On 5th 

 August found the leaves of Vaccinium eaten in several small patches, and a 

 sprinkling of tiny frass in the bottom of the tumbler. All the larvae 

 behaved as though Vaccinium were not their proper food plant, leaving it 

 and wandering around the glass, and only returning to it when they 

 found that they could not get anything more to their taste. I have, how- 

 ever^ since then, seen the same thing done b.y the larvae of a Noctuid, 

 the eggs of which were found on the leaves of a shrub, and I therefore 

 judge that it is owing either to a desire to explore their surroundings or 

 because they object to the confinement. The frass from the young larvcC 

 must have been ejected with considerable force, a;^ the jar was always 

 sprinkled half way up the side. The mortality, through drying up 

 apparently, was very heavy, and by the 15th of the month only five 

 remained out of fifteen, and in my despair I wrote to Mr. Scudder for sug- 

 gestions, and on the 17th received an answer from him describing his 

 method of unconfined feeding. I then filled a homoeopathic vial with 

 water, bored a small hole in the cork, and inserted a small sprig of Vac- 

 cinium. The vial I placed in a wineglass, with earth around it to sup- 

 port it, in order that should the larvae fall off the leaves they would be 

 caught, and also to decrease the danger of their straying. The earth I 

 watered, so as to render the air about the larvae slightly moist. I then 

 transferred all that remained alive, viz., three, as two had perished since the 

 15th, to the sprig. The following day I found that one had not moved from 

 the spot where I placed it, and was apparently dead and drying up, but 

 the two others were healthy, and thenceforward I had no trouble, and 

 carried these two right through to imago. One of these larvae passed 

 first moult on i8th August, and the second on the 20th. Just before the 

 moult the larva seems quite smooth. 



After first moult : Length about 3.9 mm., rather plump, colour dull 

 green, head same colour as body, head and body covered with very short, 

 minute whitish hairs, giving a shagreened appearance ; faint, darker green 

 longitudinal lines are visible under a lens.
