120 LEPIDOPTERA. 



Whole body studded thickly with minute tubercles. Belly 

 purplish grey. Central ventral line dusky purple, margined 

 with white. Resembles the pink variety of the larva of 

 E. nanata; the lateral stripes also remind me of the larva 

 of £'. vh^gaureata. Feeds on Artemisia campe.stris, ZeWer, 

 and according to Knoch and Schvvarz on A. absynthium 

 and vulgaris. The larvae sent me by M. Zeller were full 

 fied, Oct. 6 — 10th. Pupag inclosed in an earthen cocoon. 

 Thorax and wing cases pale yellowish green. Abdomen pale 

 yellowish red, segmental division dark red. 



Description of Larva of Eup. fraxinata, Crewe.* 

 Long, smooth, tapering towards the head. Ground colour 

 uniform dull-green. Segmental divisions yellow. Central 

 dorsal line dingy-green or purple, very indistinct, except on 

 the anal appendage, where it is dilated into a large dark 

 purple spot. Spiracular line yellow. Belly whitish, wrinkled, 

 central ventral line dark green. A variety rarely occurs in 

 which the central dorsal line is wanting and its place is 

 supplied by a series of dusky triangular blotches, becoming 

 faint or evanescent on the anterior and posterior segments. 

 On each side is a row of slanting yellowish stripes, tinged 

 with pink. Pupa enclosed in a cocoon under moss, on the 

 trunks 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. 

 Mr. Greene and myself have for some years been in the 

 habit of taking both larvae and pupae, and we never found 

 them upon any other plant. The larva will eat flowers of 

 laurusHnus if reared from the eg^ in confinement. It is full 

 fed at the end of August and beginning of September. 

 Perfect insect appears at the end of June and throughout
