934 THE ENTOMOLOGIS'T. 
been much discussed in our entomological journals, but it was 
last raised by Mr. Hodgkinson (‘ Record,’ iii. 85) asking whether 
the species had occurred again. Mr. Tutt, in a note, replied :— 
“The last record should be well known to Mr. Hodgkinson. It 
is in the E. M. M. vol. xxiv. p. 181, and is vouched for by Mr. 
Webb. Mr. Edmonds has sold a large number of pupz of late, 
but no one supposes they are of British origin.” This refers to 
the 1887 captures; and if, as Mr. Webb tells us, Mr. Tutt was 
perfectly conversant with the fact of their annual occurrence. at 
Sandwich (i. e., in 1888—89—90—91), it appears a strange 
answer to Mr. Hodgkinson’s plain question, which related not to 
the record, but to the occurrence, of the species. Probably, 
however, Mr. Tutt agreed with my opinion, that this emasculated 
record was not sufficient to enable it to be quoted, and, therefore, 
very properly ignored it.

ON BREEDING PARNASSIUS DELIUS. 
By Leronarp 8. SELLOon. 
Tuts year I have been fairly successful in rearing P. delius 
from larve, and venture to give the following account of my 
experiences. 
I obtained sixty-two larve in May by searching the food- 
plant (Sazifraga aizoides) at an altitude of about 5200 feet. 
These were of all sizes, some nearly full-fed, others quite small. 
The first larva I obtained on May 17th, and it was then about 
half-grown; but some taken at the same altitude much later were 
still quite small. On the 24th of June I took six more larve at 
6500 feet. ‘These were also of various sizes. 
These sixty-eight larve (with the exception of half a dozen, 
which I preserved) I fed on the growing plant of Sasxifraga 
aizoides, and they all turned to pupe, with the exception of four 
or five, which escaped from the cages. The food-plant grows in 
exceedingly moist situations, in fact often in the water; and I 
therefore kept the plants on which my larve were feeding very 
moist, by watering the whole cage, plant, larve, and all, very 
freely, at least twice a day. 
The first larva spun up, among the food-plant, about the end 
of May. ‘The cocoon is very slight, and the pupa can easily be 
seen through it. 
The first imagines appeared on July 6th (one male and one 
female), and others followed through July until the 29th; after 
which date there were no more emergences until August 19th, 
when one male appeared. Altogether forty-two imagines were 
bred, of which twenty-four were males and eighteen females,
