HESPERID.E, 277 



obscured by the dark colour. The portion of the nei-vures 

 forming an angle at the apex of the discal cell of the fore 

 wings is also blackened, in this specimen, so as to form a 

 quite unusual discal streak. On the under side of the fore 

 wings this appears more distinctly as a black discal spot, 

 such as I have seen in no other specimen of this species. 

 Its antennjB are black above to the tip, but yellow on the 

 under side, and with the exception of the black discal spot 

 the under side of the wings is quite normal. A specimen in 

 Mr. Sydney Webb's collection is entirely fulvous on the upper 

 side, being destitute of the usual dark brown marginal colour 

 and streaks on the nervures. 



On the wing in July and the beginning of August. Colonel 

 Randall states that he has taken it twice in Monmouthshire in 

 May, but this seems an altogether exceptional circumstance. 



Larva more than three-fourths of an inch in length, 

 stoutest in the middle ; tapering a little towards the head, 

 also to the tail, which is slightly flattened and rounded off ; 

 head globular and projecting, larger than the second segment, 

 which is remarkably small and short ; under surface flat, 

 and legs placed well beneath. Colour a tender and delicate 

 light green, without gloss, but sprinkled on some of the 

 anterior segments with black points of extreme fineness, so 

 that they do not affect the delicate green colour ; head rather 

 deeper green, rough with minute points ; upper lip pinkish ; 

 smoother and deeply channelled ; ocelli black ; dorsal stripe 

 very narrow on the second segment, thence uniformly wider 

 to near the tail, where it becomes very gradually attenuated on 

 the anal flap, bluish green, having a stoutish line of paler 

 green running through the middle, and bordered outside, in 

 stronger contrast, by lines of pale green ; sub-dorsal line pale 

 green, spiracles prominent, of a reddish flesh colour ; beneath 

 these at a little distance is an inflated paler stripe of almost 

 creamy whitish extending round the anal flap ; under surface 

 and legs green, except that on the front of the ventral sur-
