Description of the Larva of Lycama Alexis (Common 

 Blue). — The eggs are laid on Ononis spinosa (rest-harrow), 

 and the young larva3, when they emerge, feed on the leaves 

 of this plant, on vvhich they may be found resting much after 

 the manner of a Chiton, a shell vvhich in form they somewhat 

 resemble. Head very small, glabrous, oblong, porrected in 

 crawling, otherwise withdrawn into the 2nd segment and 

 totally concealed : body convex above, flattened below, 

 rounded at both extremities, dilated and lobed at the sides : 

 the divisions of the segments conspicuously marked : spi- 

 racles situated much above the lateral margin, the posterior 

 pair dorsal : whole surface covered with extremel}' minute 

 warts, each of which emits a hair. Colour of the head 

 intensely black, of the body green, sometimes bright apple- 

 green, at other times dull olive-green ; a medio-dorsal stripe 

 rather darker ; a narrow lateral stripe below the spiracles, 

 but above the lateral lobes, much paler, almost white ; be- 

 tween the dorsal and lateral stripes there are, on each side 

 of each segment, three pale oblique lines, their inclination 

 being from the anterior to the posterior margin of the seg- 

 ment ; the minute warts black ; legs, claspers and ventral 

 surface of the same green hue as the body. Towards the 

 end of July they undergo pupation : the pupa is rounded at 

 both extremities, and is without angles ; the anal extremity 

 is without the usual minute hooks for attachment; the region 

 about the head is furnished with minute bristles : the colour 

 is dull green ; the head, extremity of wing-cases, and ventral 

 surface of abdomen tinged with brown. The butterfly ap- 

 peared on the 12th of August. I am indebted to Mr. Double- 

 day for the larvae of this insect. — Edward Newman. 



Description of the Larva of LohopJiora viretata. — Feeds

 June, when it rests in a somewhat arched posture, the ante- 

 rior part of the body being held quite free of the food-plant,
