of the weather, with the presence or absence of sunshine, is 

 largely influential. The result of this susceptibility to 

 external influences is that the butterfly is seen on the wing 

 in different years in every month from March to October or 

 even November. 



Lahva, one inch in length when full grown ; of a soft 

 velvety appearance from a covering of fine pubescence ; very 

 bright green slightly inclining to olive-green, with a darker 

 green dorsal stripe attenuated at each end, and margined by 

 a greenish-yellow line ; sub-dorsal lines greenish-yellow, 

 margined above by a fine line of a darker green than the 

 ground colour ; a little below are three parallel undulating 

 lines of faint greenish-yellow ; spiracles flesh coloured ; last 

 segment with two blunt, whitish or flesh-coloured, terminal 

 points. 



On first emerging from the egg it is pale greenish white, 

 with darker dots, long pale curved hairs, and some black 

 bristles on the head, which is large and of a brilliant jet 

 black. After the first moult the head becomes green, and 

 the general colour pale green with a deeper green dorsal 

 stripe and a whitish sub-dorsal line ; the anal points are now 

 developed and pink, and the bristles are more numerous. 

 After the nest moult the hairs still increase in abundance, 

 and the colour is of a more vivid green, and after the third 

 moult the adult colouring and markings, as already described, 

 are gradually assumed. (Buckler and Hellins). 



On Dactylis glomerata, Triticum rcpcns, and other coarse 

 grasses. As in the butterfly, the larva is irregular in its 

 times of feeding, and may doubtless be found occasionally in 

 almost every month of the year. One brood, reared by the 

 Rev. J. Hellins, hatched from the egg on July 5th, and were 

 full fed about the 27th of the same month, but those from 

 eggs obtained in September passed the winter in the larva 

 state, and fed on till the beginning of May. Hybernation 

 seems to be partial and dependent upon the severity of
