200 THE ENTOMOLOGIST. 
V. Urtice, earliest, March 24; latest, June 27 (disappearing 
the whole of May). V. Polychloros, earliest, March 28; 
latest, May 2. Pieris Brassice, earliest, April 7; latest, 
June 27. P. Rape, earliest, April 20; latest, June 27. 
P. Napi, earliest, April 25; latest, June 9. Anthocharis 
Cardamines, earliest, April 29; latest, June 9. 
The remaining five species were only seen once each; and 
of the ten, previously mentioned, I noticed five during the 
first fortnight in July, namely,—Pieris Brassice, P. Rape, 
P. Napi, Vanessa Urticz, and Satyrus Janira, as well as two 
additional species that I had not observed from March to 
June inclusive,—Satyrus Hyperanthus, July 3 and 4, and 
Thecla W-Album, July 10. 
From the foregoing statistics it will be perceived that of 
the above fifteen species, so far at any rate as my own 
observation went, Gonepteryx Rhamni (male) was the earliest 
seen, on the 18th of March, and Polyommatus Alexis and 
Pamphila Sylvanus the two latest, on the 9th of June. That 
the two kinds, moreover, most frequently noticed, were Pieris 
Rape, seen on twenty-three days, and P. Brassice, on nine- 
teen ; next to these, Vanessa Urtice and Gonepteryx Rhamni, 
seen respectively on fourteen days; and next, Pieris Napi, 
Anthocharis Cardamines, and Vanessa Io, which were each 
observed on twelve days. Also that of the tribe of whites, 
which, as regards the number of individual specimens, do 
not appear to be particularly numerous this season, Brassicze 
occurred nearly a fortnight before Rapz, more than a fort- 
night before Napi, and three weeks before Cardamines; that 
Rapz was seen five days before Napi, and Napi in its turn 
four days before Cardamines; that the earliest. Satyrid 
(P. Egeria) was observed nearly a month previous to any of its 
congeners, on the 23rd of April, later than two species of 
Pieride, Brassice, and Rape, and earlier than another two, 
Napi and Cardamines; that the three remaining species of 
Satyridz were later than the two latest species of Pieride ; 
that Megera occurred ten days before Pamphilus, and thirty. 
days before Janira; that Pamphilus and Egeria were only 
seen once each, but Janira and Megzra seven times in each 
case,—the appearances of Janira, however, being restricted to 
June, and Megera, on the other hand, ranging over the two 
months, May and June, being noticed three times in the
