oiic-tlilivl from the beginning, and three others near tlic end ; tlie anterior k'gs 

 developed in gradation, the shortest pair in front, the second pair a Httle longer, and 

 the third pair the longest ; the ventral and anal pairs well developed. 



In colour the head is pale greenish-white in front, light glaueous-green at the 

 sides, reticulated with whitish ; near the crown, on each lobe, is a black streak un- 

 didating down to the antennal papillus, and bounding the whiter face from the 

 greener side of the head ; above the mouth is a triangular mark of blackish-brown 

 atoms : the ground colour of the body generally is a pale blue-green, that of the 

 back has a more lively green tinge, though so pale as to be a greenish-white ; through 

 the back can be distinguished the dorsal line by its bluer tinge, besides a small streak 

 on either side of it anteriorly on each segment, excepting the thoracic, wliich 

 are broadly divided with it ; but the chief feature of the back is the row of black 

 spots, viz. : one rather oblong spot on the whitest portion on each thoracic segment, 

 and on the others an oblong spot just at the beginning, and another thicker, of a 

 blunt spear-head shape, about midway towards the end of each segment, and a small 

 spot on the anal tip, — these are upon the dorsal line ; along the boundary of the 

 whitish colour of the back runs the row of sub-dorsal black dashes ; these are short 

 and situated midway on the thoracic segments, and on the others are behind the first 

 wrinkle extending nearly to the segmental division ; these vary in individualsj being 

 in some simple oblong dashes, while in others they appear open at one end, and in 

 others again at both ends, suggestive of parallel streaks run together in the middle ; 

 but in all, each of these dashes is bounded below by a greenish-white dash of the 

 same extent, followed by a group of two or three small angular black spots or streaks, 

 amongst which is the spiracle, which, though appearing blackish, has a faint flesh- 

 coloured centre ; next runs the inflated greenish-white sub-spiracular stripe marked 

 with a black dash at beginning of each segment, except on the anterior ones, which 

 are marked in the middle with a squarish spot, and a small black spot is at the base 

 of each anterior leg ; the belly has a central faint greenish-white line with a black 

 elongate mark on it at about the middle of each segment from the fifth to the ninth, 

 both inclusive ; a little more behind, on each side the central line, are a twin pair of 

 black specks, and a couple of greeiiish-white spots on each side at the beginning of 

 each of these segments ; a very small black mark is at the inside base of each anterior 

 leg : the anterior legs are glistening, the head and body are smooth without gloss : 

 the tubercular dots are excessively small and dusky, each emitting a fine bristly hair. 



The pupa measures about lialf'-an-inch in lengtli, and in its gi'catest diameter, at 

 the ends of the wings, one-eighth of an inch ; the eye-covers rather prominent, and 

 tlie abdominal divisions deeply cut, the anal tip bearing a spike finely forked at its 

 extremity : at the end of the first week the wings were olive-green, the other parts 

 brown, the anal spike blackish ; the whole surface glossy. — William Buckleb,

A new British Torlrix — Allahia argentana, CI. — On Jidy 10th I found a in-ctty 

 white moth, which was evidently a species new to our lists, flying amongst the grass 

 on the side of a mountain in Athole, Perthshire, and liaving called the attention of 

 my companions, Sir Tliomas Moncreiffe and Mr. W. Herd, to it, we managed to 

 secure a few more specimens. This niiilli, Sir T. jMoucrcifTe has evince iilenfilicd with
