meeting near their points ; the wing-cases were well defined, but not very projecting : 

 its colour at first was a light reddish-brown which changed gradually afterwards 

 to darker brown, the abdominal divisions a little paler than the rest and with little 

 gloss, the other parts being highly polished. — William Bucklee, Emsworth : 

 October, 1872. 



Description of the larva of Euholia lineolata. — A specimen of this insect which 

 I captured on the Cheshire sand-hills in the early part of April last deposited a few 

 eggs. They were in httle clusters, each batch containing eight or ten eggs ; their 

 colour was at first pale yellow, but soon changed to bright ochreous-brown. On April 

 30th, they had become slaty-brown, and on the following day the young larvae 

 emerged, their colour orange, tinged with green. They fed readily on Qalium 

 saxatile, though Qalium verum is probably their natural food, as it grows abundantly 

 on the sand-hills. On June 8th, I took down a description as follows : — -Length 

 about seven-eighths of an inch, slender, and of nearly uniform width throughout. 

 Head a little broader than the second segment and slightly notched on the crown ; 

 the face rather flat. Body cylindrical and very slightly attenuated from the 11th 

 to the anal segment. Skin tough, along the sides and at the segmental divisions 

 rather wrinkled. 



Ground colour pale olive-green, at and on each side the segmental divisions 

 pink ; head greenish-yellow, spotted with black. Dorsal line dark green, and there 

 is a still darker and much broader smoky stripe above the spiracles ; between this 

 stripe and the dorsal line are two faint waved ohve-brown lines. The ventral surface 

 is bright yellowish-green, with paler central stripe ; the segmental divisions sulphur- 

 yellow. The larvae went underground and changed to pupa about the middle of 

 June ; the latter is about a quarter of an inch in length, smooth and shining ; 

 very dark brown, with the abdominal divisions pale brown. — Geo. T. Poeeitt, 

 Huddersfield : October 17th, 1872. 



Notes on forcing Acidalia larvcB. — Last year, having succeeded in forcing the 

 larvffi of Acidalia strigilata by placing them in a greenhouse, I was induced this 

 season to try the experiment with other larvae of that genus ; and, as it has proved 

 a success, I venture to send a few notes as to the mode of treatment. 



I feed the larvae up in the usual glass cylinders, placing calico round them tD 

 exclude the sun's rays, which, reflecting through the glass, would no doubt quickly 

 kill the larva and wither the food-plant. As soon as the larvae are about to assimie 

 the pupa state, I place mould in a saucer, and, to prevent it becoming saturated with 

 moisture from the evaporation of the water beneath, I slightly raise it to admit a 

 current of ah' passing beneath, and also place a block of wood in the centre, with a 

 hole through it to admit a plant. It is essential to do this, for, if the plant come in 

 contact with the mould, dampness is diffused through it in a very short time. 



The following are the particulars of the species bred : — Acidalia strigilata ; 

 from twenty larvae reared seven moths, which appeared from 21st September to 20th 

 October, 1871, the remaining larvae hibernated. A. trigeminata ; bred a number of 

 moths from 26th August to 20th September, no larva hibernating. A. emutaria ; 

 faom twelve larvae bred ten moths, which appeared from 27th August to 1st Septem-
