30 Mr. J. W. Tutt on recent Experiments in 
I8¢y 3 I am obliged to term these “ intermediates,” 
as they will not fall into any of the above 
divisions. They are moderately well-marked 
and might be looked upon if found in nature 
as odd aberrations of either species. Need- 
less to say, such forms do not to my know- 
ledge occur in nature.* 
2° Unclassified. Quite distinct from any- 
thing that I have ever seen. 
376 : ue One emergence on November 4th; 14 
pup still left on November 10th, 1897. 
VI. Insrep Hysrips.— gf (f TZ. histortata x 2 T. 
crepuscularia) x 2 (gf T. bistortata x 3 T. crepuscularia). 
—From two batches of eggs :—(1) Paired August 10th ; 
ova laid August 12th; hatched during the fourth week of 
August, some only fertile: (2) Paired August 13th; ova 
laid August 15th; hatched first week in September. By 
October 22nd all except 13 larvee had pupated. The 
first two imagines emerged on November 4th, fine full-fed 
larvee at that date not having gone down. 5 specimens 
examined, 3 ¢ and 2 2 ; emerged between November 
4th and 10th. 
et 2 These are again perfect intermediates be- 
tween TZ’. bistortata ab. consonaria and 7. 
crepuscularia. The larger size of the 2, the 
uniform grey tint, the ill-defined markings 
all lean to the former, whilst the squarer 
wings approach the latter. 
ies Of a cleaner and better marked type. 
Difficult to place, but certainly more nearly 
approaching 7’. crepuscularia. 
32 22! The brood only just commencing to appear. 
This cross is similar to the two which follow, but two 
months later. They are not so very dissimilar from the 
first section (12 ¢ 1 ¢) of Bacot’s Batch VI, but very 
different from the 9 @ specially described. 
* IT use the term ‘‘ intermediate” simply to include those speci- 
mens in which the characters of both parents are more or less defined 
without any very strong tendency towards either.
