 Mr. Buckler describes the larva as follows : — The full-fed larva is 

 little more than than three-eighths of an inch in length, cylindrical, 

 though tapering a little behind ; the head a trifle smaller than the 

 second segment, and rather rounded, greyish- brown in colour, and 

 marked with blotches of blackish-brown on the lobes and between 

 them, and is very shining ; the body is pale glaucous-green, and has 

 a very broad dorsal stripe of darker bluish-green, through the middle 

 of which runs an exceedingly fine pale thread of the ground colour ; 

 the shiny sub-dorsal line is yellowish-white, and just above it is a 

 whitish-grey parallel streak : all these are regularly interrupted at 

 segmental divisions, these divisions are somewhat yellow ; the spira- 

 cles are whitish ringed with brown ; there is a white wart on the 

 hinder part of the side of the third and fourth segments ; all the 

 tubercles are whitish, each bearing little fascicles of about four white 

 silky hairs, curved and finely pointed ; the ventral surface and legs a 

 little paler than the rest of the ground colour " (" Entomologist's 

 Monthly Magazine," Vol. VIII., p. 158). With regard to the possi- 

 bility of this species having another foodplant, Mr. W. G. Sheldon 

 writes : — " As far as I can ascertain, Leioptilus lienigianus has not yet 

 been recorded as occurring in Surrey. On the 18th July last, I captured 

 a specimen which was feasting on the flower of a thistle. I have 

 since made a careful search for its food-plant (Artemesia vulgaris), but 

 am unable to find it within two miles of the spot where the specimen 

 occurred. As the species is endued with only a limited power of 

 flight, it therefore seems possible that there may be some other 

 pabulum " (•' Entomologist," Vol. XXL, p. 113). 



Pupa — -The pupa is described by Mr. South as follows: — "Whitish 

 green, with a fine yellowish line down the centre of back, and a few 

 oblique dark dorsal markings ; warts and hairs similar to those of 

 larva. The oblique markings vary in intensity, sometimes giving the 

 whole dorsal area a brown coloration ; wing-cases green, antennae 

 and legs darker anterior. Sometimes the upper part of the pupa is 

 yellowish, with a pink tinge, and the oblique stripes reddish brown. 

 Fixed by tail to under side of leaf of mugwort of food plant, 

 looking not unlike the larva at rest. June " (" Entomologist," Vol. 

 XV., p. 105). Of the habits of the pupa, and the way in which it is 

 protected by its environment, Mr. Barrett writes : — " Early in July, 

 1870, in a country lane some miles from Norwich, I chanced to find a 

 plant of Artemisia vulgaris, the leaves of which were eaten in a 

 fashion different to anything I had before seen, so curiously indeed 

 that I could not at that time imagine to what family even the larva 

 could belong, and to make the matter worse, it appeared to be quite 

 deserted. At home 1 again examined the plant, but, finding nothing
