Dr. T. A. Chapman on Calloj)lirys avis. 
in front of vein two, but is bright towards the costa (space between 
six and seven), and fades towards the inner part of the wing. The 
row of spots in C. rubi is much more irregular. The first spot on 
the hindwing slopes inwards, in C. rubi it slopes outwards, giving 
the second spot the appearance of being displaced inwards in G. rubi, 
outwards in G. avis. The appendages have only slight differences. 
I have not examined sufficiently numerous specimens to be able to 
assert that these are constant. 
“ It specialises in its foodphuit, instead of being quasi-omnivorous 
like G. rubi. 
“Habitat, Southern France (Var, and Pyrdnees-Orientales),Morocco 
(Tangier). The only specimen I have seen, not in my possession, is 
one in the Brit. Mus. Collection, ranged with G. rubi var. fervida, 
and labelled ‘ Tangier, Elwes Coll.’ ” 
My original description does not need much amplifica¬ 
tion, but one or two points deserve notice, perhaps the 
most important is in the lengths of the palpal joints, a 
reference to Plate XXI will show that in C. avis the second 
joint is rather longer and stouter than in G. ruhi, but the 
last joint definitely shorter’. 
The white line on the underside is really often slightly 
tinted green, especially beneath the forewing; sometimes 
it is continuously a line, at others, and more usually, a 
little broken up. Sometimes it is nearly a straight (or 
curved) line. In other specimens, on the hindwing, tlie 
costal spot, for example, inclines inwards, the next three are 
nearly in line quite outside this, and the fifth and follow¬ 
ing spots are again further out. In C. rubi, the spots are 
always in a continuous chain, sometimes in a regular line 
(or curve), at others with some zigzag. 
In G. avis, apart from some variation on the forewing, 
all the spots are present and the total variation is com¬ 
paratively small. In C.-ruhi, as is well known, they vary 
to the greatest extent, as to some, more, or all being absent. 
The general position of the line is much nearer the base 
of the wing than in G. rubi. In (7. avis it is, for example, 
on the hindwing very near the end of the ceil; in C. rubi 
it is much nearer half-way between the cell and the hind 
margin. 
The red colour beneath the knob of the’antenna strikes 
one as a novelty compared with the more familiar G. rubi, 
and one is inclined to assume that the black area in G. rubi 
is scaled. It is, however, the case that the scaled and
