considerably ; dorsal stripe almost white ; laterals and interme- 

 diate spaces all grey ; remaining dirty red. The whole skin 

 appears greasy ; the dorsal rows of hairs have become quite stiff, 

 jet black, but each radiating clump is centred with four or five 

 grey hairs ; laterals in some cases have almost vanished ; the 

 warts are very prominent now, black and shining upon the pale 

 ground. The head also jet black, highly polished, and deeply 

 notched in the centre. 



I fed the larv?e throughout upon common groundsel, as they 

 did not seem to do well upon any other plant. In handling, the 

 bristles enter the skin, causing a slight irritation. 



June 12th. Two pupated ; the larvas settled in the corners of 

 the box and spun an extremely light cocoon of white silk, not 

 strong enough to support them, as both fell out and pupated 

 upon the soil. A^'hen first formed the pupa is pale reddish, 

 with the tubercles, &c., showing distinctly, but within twelve 

 hours the whole becomes jet black and polished ; anal angle 

 smooth and rounded, immovable ; it greatly resembles the pupae 

 oi E. jacohcua. Other larvffi pupated up to July 25th, right in 

 the centre of the Aira plants, forming small and very frail egg- 

 shaped cocoons. Several died, but many were infested by a 

 small Microgastcr, which emerged from all portions of the host, 

 and spun up small white cocoons ; the liies from these were 

 black, with red legs. They began emerging during April. 



July 12th. The first imago of E. crihrum emerged, and from 

 that date the dates of emergence were as follows : — 



Several specimens bred were cripples, but these are not 

 included in above. 



It may be interesting to give the dates of capture of the 

 imago in the Eingwood locality : — June 13th, a female ; June 

 21st, thirteen ; June 27th, fourteen ; on July 3rd and subsequent 

 dates I went for it, but did not see any. The Eingwood ground 

 for this species is about fourteen miles from its Bournemouth 

 haunts. 



The series bred are more typical than I get here ; one male 

 has a beautiful black central band, a few are almost black, the 

 grey nervules being conspicuous, but nothing very remarkable.
