COLIAS EDUSA. 57 



of males in the early part of the flight-time, and of the 

 females later. The total absence of C. Hyale is also noticed 

 by several. Very many other occurrences have come to my 

 knowledge privately, but they are not included, as the distri- 

 bution has been general, extending from Orkney (W. Tait) 

 to Land's End (H. Miller), and from Pembroke (C. G. 

 Barrett, in E. M. M.) to Lowestoft (R. Laddiman). The 

 above, together with the records of the early appearances, 

 which are tabulated in the July and August issues (Entom. 

 X. 187, 209), are ample to show the comparative earliest and 

 latest dates; also the occurrence of Helice. The comparative 

 absence of life-history notes is to be regretted. If the 

 collectors, who now boast of their one, two, or even three 

 thousand specimens, had set apart but one day to the 

 obtaining of eggs, it is evident that both themselves and 

 their favourite Science and pursuit would have been benefited 

 and rewarded. What 1877 — the great Edusa year — lacked, 

 1878 should have been able to make good. From the 

 number of specimens taken there certainly ought to be ample 

 materials for a continuation of the species in entomologists' 

 hands, either as eggs, larvae, pupae, or hybernatiug imagos. 

 Prudens futuri. Where are they ? 



In addition to published notes in the 'Entomologist' 

 (Entom. X. '210, 285), the following relate to life-history: — 



I obtained about twenty eggs from two females, about 

 August 5th or 6th. These hatched in about twelve or 

 fourteen days, and fed till October 7th, when one changed to 

 pupa. The others im fortunately died, from some cause 

 not known to me, after the last change of skin. A male 

 Edusa emerged from the said pupa on the 2nd of November.

I took a worn female Edusa at St. Helen's, Isle of Wight, 

 on September 26th, which I put under a net. In a short 

 time it laid about twenty eggs, and a iew more the next day. 

 They were laid on two species of clover, and also on the net, 

 one by one. They have since all collapsed. — H. Golding-

On September 6th I captured a female, which I pill-boxed, 

 and afterwards placed under a glass cylinder, with a sprig 

 of clover in blossom. On the 13th I found she was dead, 

 and had deposited about fifteen eggs, which commenced to 

 hatch on the 17th. I supplied them with a growing plant of 

 clover, upon which they commenced feeding but very slowly ; 

 and I have at the present date one or two larvae remaining,
