EUPITHECIA FEAXINATA. 33 



of ash, long, slender, and tapering. Thorax and 

 wing-cases dark olive. Abdomen still darker, almost 

 black, tinged posteriorly with red. 



Feeds exclusively on ash. The Rev. Joseph Greene 

 and myself have for some years been in the habit of 

 taking both larva3 and pupae, and we never found 

 them upon any other plant. The larvas will eat 

 flowers of Laurustinus if reared from the egg in con- 

 finement. It is full-fed at the end of August and 

 the beginning of September. The perfect insect 

 appears at the end of June and throughout July.

EUPITHEOIA DENOTATA = PIMPINELLATA. 



Plate CXXXII, fig. 6. 



This larva, in size and general appearance, closely 

 resembles that of E. fraxinata. It is long, rather 

 slender and tapering towards the head. There are 

 two varieties. 



Var. 1 is green, with three purple dorsal lines, the 

 centre one broad and distinct, expanding considerably 

 on the anal segment, the two side ones very indistinct. 

 Head and prolegs purple. Segmental divisions and 

 spiracular line yellowish. Belly green. Back studded 

 with a few minute white tubercles, interspersed here 

 and there with a black one. 



Var. 2 is of a uniform purple, with two lines of a 

 deeper shade on each side of the back. It feeds, as 

 far as my experience goes, exclusively on the flowers 

 and seeds of the lesser burnet saxifrage (Pimpinella 

 saxifraga), and is full-fed throughout the month of 

 September, and occasionally at the beginning of 

 October. It prefers the hedge-sides and banks. It 

 is fearfully infested with ichneumons, not above one 

 in ten escaping. 



The pupa is enclosed in an earthen cocoon ; there
