60 
emerged. June 11th it rained and turned much colder, only 5 emerging. 
June 12th to 14th were very cold, and only a few emerged. On 
the 14th I found a pair of Prunaria in copula. On the 15th, it rained 
all day and only one female emerged, which paired the same evening 
with the same male that came out on 14th. It is not at all an uncom¬ 
mon thing for Prunaria to pair a second time. I have seen several such 
pairings during my acquaintance with Prunaria, but in each instance 
(except the present) the ova of the second pairing have proved infertile. 
On the other hand I have had five pairings this year (1903) resulting in 
infertile ova, although copulation in every case lasted from 12 to 24 
hours, and the normal number of eggs were laid. Probably their being 
the fifth years inbred stock had something to do with it, although the 
moths paired were amongst the largest I have every bred, and larger 
than the ordinary type. The 23rd, although cold, was a brilliant sunny 
day, the first sunshine after thirteen days of rain, during the last 
eight of which nothing emerged. After this Prunaria came out freely 
till the end of the month. In all 437 imagines emerged, as follows : 
Brood 1.—13 emerged, B js, usual orange type, 5 ¥ s, usual yellow type.

In connection with these broods the following points may be 
noted :— 
Brood 1 includes a male with a cross in the centre of each wing, 
giving it a striking appearance, also a female approaching very near to 
this. Brood 2, two dwarf banded males, one with hindwings bleached 
a light unicolorous brown, the other with bleached hindwings of a 
unicolorous dirty-brown. Brood 4 produced the only female of the 
new ab. Pickettaria. I kept it a long time waiting for a male 
Pickettaria to emerge, but did not get one in time. Brood 5, one 
female showed an attempt to throw back to the usual yellow form, 
on the right hand forewing the deep chocolate band is suffused and 
broken, showing the yellow markings crossing the band. Brood 6, 
one male is worth notice ; it approached the curious female of brood 
5, with the chocolate band suffused with yellow on the right forewing 
This male has both the hindwings suffused in the same way, and the 
chocolate bands are broken up and are mixed with the orange. Brood 
7, the only male ab. Pickettaria came out in this brood.
