terminates in a cluster of minute hooks, by which it is sus- 

 pended from the web ; the colour is umber-brown, delicately 

 reticulated with black lines ; on the back, in the depression 

 between the thorax and abdomen, are three or more blotches 

 of beautifully burnished silver. 1 am indebted to Mr. Wright 

 for both the larva and pupa of this butterfly. — Edward

Description of the Larva of Satyrus Megm-a (Gatekeeper). 

 — This species is double-brooded : the eggs which produce 

 the first brood of larvae are laid on Dactylis glomerata and 

 several other species of grass, at the end of May : the larva 

 is full-fed about the middle of July, when it rests, by day, in 

 a nearly straight position on a blade of grass, feeding chiefly 

 by night. Head subglobose, exserted, wider than the 2nd 

 segment, which is restricted in front. Body somewhat fusi- 

 form, gradually decreasing to each end, decidedly convex 

 above, somewhat flattened beneath ; dorsal surface trans- 

 versely wrinkled, the wrinkles dividing each segment into six 

 sections, of which the anterior is the largest ; the body ter- 

 minating in two parallel points directed backwards ; entire 

 surface, both of head and body, covered with minute warts, 

 which impart a scabrous appearance to the larva ; each wart 

 emits a short bristle ; on each side below the spiracles is a 

 decided but inconspicuous skinfold. Colour apple-green, 

 the head and an indistinct narrow medio-dorsal stripe rather 

 darker ; the latter appears to be little more than the food in the 

 alimentary canal showing through the cuticle ; it is sometimes 

 entirely absent; a lateral stripe paler; there is also a narrow 

 and very indistinct stripe exactly intermediate between the 

 medio-dorsal and lateral stripes ; the minute wa'rls are gene- 

 rally, but not invariably, white ; the bristles either black or 

 white ; the legs semitransparent and almost colourless ; the 

 claspers concolorous with the body ; the anal points tipped 

 with pink. Changed to a pupa, suspended by the tail, on 

 the 14th of July; this was rather obese; the head truncate, 

 broadly emarginate, the angles almost right angles ; thorax 

 dorsally humped and keeled, laterally angled at the base of 

 the wing-cases ; dorsal surface of abdomen with a lateral 

 series of six points on each side. Colour apple-green ; the 

 angles of the head, the lateral and dorsal angles of the tho- 

 rax, and five equidistant raised dots on each side of the
