Larva — Fifth stage. — Head as before. Body of a dark sagfe-green, 

 approaching to brown, and thickly set with minute black warty processes. 

 A dark dorsal line and an indistinct spiracular line (of a lighter tint than 

 the body colour) mark the larva in this stage. The spiracles are black, 

 and the fore legs black ; the pro-legs are of the colour of the body. 

 Between the loth and i ith and the i ith and 12th segments, on both sides 

 at the bottom, are conspicuous white patches (or breaks in the skin), the 

 nature of which I do not understand. The larva attained its greatest size 

 on the 24th of June. It was then an inch and two-tenths long. It con- 

 tinued to feed till the end of the month. It then became restless, and 

 shrank up considerably. On the 3rd of July it fixed upon a place for its 

 nest. It gathered the surrounding blades of grass together and bound 

 them with a net-work of silk, in which were flakes of whitish scurf 

 [Query. — Did these come from the white side patches ?]. It changed to 

 the pupa on the 6th of July. Its head-case and skin came off together 

 and fell to the bottom of the nest. 



Chrysalis seven-tenths of an inch long. Head-cover and wing-cases 

 mouse-colour. Abdomen dull yellow, with a tinge of blue above. The 

 Imago appeared on the 2 ist of July — the chrysalis case having opened 

 from the back of the head to the back of the thorax to allow of its escape. 



Imago c?  — Expanse of wings 1.6 inches; length of body .6 

 inch. Basal half of the primaries, ochre-yellow ; outer half, brown. 

 Near the apex is a broken curve of ochreous dots. In the centre of the 

 wing is a long metallic dash in a dark brown setting ; fringes brown. 

 The secondaries are brown with ochreous spots and dashes ; fringes gray. 

 Underneath the primaries are paler than above, and the secondaries are 

 sage-green with small white lunettes edged on the inner side with brown, 

 and arranged in a double curve. 



Imago $ . — Somewhat more robust in form than the male, and 

 deeper in colour — the brown prevailing. Instead of the metallic dash 

 there is merely a brown patch in the middle of the fore wing. The 

 ochreous spots on the upper side of the secondaries are more conspicuous 

 than in the male. 



The perfect insect frequents the flower-heads of So/it/ago lanceolata, 

 L., and has a bold and rapid flight. Last season I did not see a single 

 specimen at large.
