294 THE ENTOMOLOGIST. 



in the district, probably throughout the whole of South Devon. 

 Mr. Porritt, whilst in the district last year from Aug. 20th to 30th, 

 took twenty specimens, but the weather for the most part was very 

 bad (Entom. xxx. 223). Mr. A. Jones, of Shrublands, Eltham, 

 Kent, whilst at Starcross on Monday, Aug. 19th, took three speci- 

 mens, two males and one female, all of the yellow vai'iety lutescens, 

 the female laying only five eggs. Mr. Gervase F. Mathews, of 

 Dovercourt, Essex, who was also at Starcross on the 19th, did 

 not take one. Although Messrs. Mitchell and Robson, of London, 

 whilst at Starcross worked "light" several times, they failed to 

 attract liera; nor could I hear of more than three specimens being 

 so obtained this season. 



On the evening of Wednesday, August 11 th, I took two fresh - 

 looking females, which I had captured that day, in a gauze cage 

 to the ground in the hope of attracting a few males ; but although 

 I waited patiently, none came. I afterwards found that these 

 females had been impregnated, as they each laid a number of 

 eggs a few days afterwards which proved fertile. From my 

 experience of " assembling," I am inclined to think that three 

 or four newly-emerged females would attract a number of males, 

 and strongly recommend tliis means to any entomologist who 

 may hereafter visit the grounds. On August 18th, Mr. Benthal 

 had a newly-hatched female in a breeding-cage out of doors. 

 This was visited between 6.30 and 7.30 p.m. by a male, seen on 

 three different occasions, and presumably the same. It was 

 captured about 8 p.m., and put along with the female. 



The following particulars will show, under their respective 

 headings, the number of eggs laid by the various forms, viz., 

 orange, red, and yellow, when laid, date hatched, duration in the 

 egg state, also the average number of eggs laid by the different 

 forms, together with the total average for the three forms : — 



Orange. 



(1) 49 eggs; laid Aug. 14 and 15; hatched Aug. 30 and 31 ; 

 in egg state 16 days. 



(2) 163 eggs; laid Aug. 17, 18, and 19; hatched Sept. 3, 4, 

 and 5 ; in egg state 17 to 19 days.
