FURTHER BREEDING EXPERIMENTS WITH HaPLUAS 
BY F. II. FOSTER, CL.AKEMUNT, i\. H. 
In the Entomological News for March, 1901, the writer gave some account 
of breeding experiments with Haploas. Experiments were continued during 
the four following seasons with a view to determining the limits of variation 
in the race of Haploa cuiifiisa occurring near Claremont and to working ont 
more thoroughly the life histories of the other forms of the genus and their 
mutual relations. Efforts to breed successive generations from the same stock 
have been but partly successful owing to the difficulty of carrying the larvae 
in sufficient numbers through the hibernation. 
Haploa confusa 
From moths bred from wild larvae taken at Claremont in May, 1901, 
three successful pairings were obtained, viz; 
Pair Xo. /. PL 11 , Fig. i and Fig. 2 parents. 
24 (j — 14 9 ( See PI. II, Mgs. 3 to 18 for selected series of progeny) 
Pair Xo. 2. PI. 11 , Fig. ip and Fig. 20 parents. 
45 S ■ — 16 9 (See PI. II, Mgs. 21 to 36 for selected scries of progeny) 
Pair Xo. j. PI. 11 , Fig. 37 and Fig. parents. 
20 S — 16 9 (See PI. II, Figs. 39 to 54 for selected series of progeny) 
A new sup])ly of larvae was obtained in 1903 and three successful pairings 
were obtained from which were reared 
from Pair No. i

These 1902 broods present no character materially difYereut from the three 
1901 series illustrated on plate.
