])r. T. A. Chapman on CaUo'phrys avis. 93 
over his series of C. ruhi in search of any intrusive 
C. avis. 
He writes me that he “ has found one specimen taken by 
his colleague Prof. Tavares in May at Jerez. It is one of 
two specimens, of which one is C. ruhi, the other C. avis, 
with the hindwings somewhat worn. The distinction is 
perfect. I have also examined more than twenty speci¬ 
mens from the neighbourhood (Sao Fiel), from Lisbon and 
from Algarve, all of which are G. o'lchi.” 
Spain can thus be added to the habitats of C. avis. 
On October 26th, 1909, M. C. Oberthiir wrote me that he 
had just received from Tunisia two specimens that appear 
to be G. avis, and later, after actual comparison, he tells 
me that they certainly are G. avis (2 ^ from Aiu-Draham 
(Kroumirie), Tunis. 
Unfortunately, by the time I liad “ spotted ” my butter¬ 
fly at Amelie-les-Bains the weather became dull and 
unsettled, so that I can say little of its habits. It can fly 
strongly in good weather, but does not stray far from its 
proper habitat. It affects (for feeding probably) flowers of 
a species of Etqihorhia, where it is sometimes accom¬ 
panied by specimens of C. riibi. Owing to weather, I 
had no opportunity of seeing it orient itself in the sun 
as G. rubi does. 
The butterfly I saw ovipositing on April 20th was lay¬ 
ing her eggs on the flowers (?), calyx really, of Goriaria 
myrtifolia.* I found at this date that two $ $ that I had 
placed on Gytisus spinosibs (or closely allied species), which, 
by their joint distribution, seemed to be the chief food- 
plant of G. rubi at Amelie, three days before, had laid 
only two eggs. They began to lay at once when given 
Goriaria. Un April 30th an egg laid wild, hatched; eggs 
laid in confinement began to hatch on May 8rd. 
The following are my notes of experiments on the food- 
plants of G. rubi and G. avis. They show that G. rubi 
would not touch, or only sparingly and ineffectually, the 
foodplaut of G. avis. Whilst G. avis absolutely refused all 
the ordinary pabula of G. rubi. 
May 26th.—Placed some newly-hatched larvae of 
G. rubi, j^arents taken amongst Goriaria at Vernet-les- 
Bains, on Goriaria, and found that they refused for 24 
* The local botanists (Messrs. Raine, Powell, Jehandiez, etc.) say 
that Goriaria myrtifolia does not grow near Hybres, it follows that 
C. ori.s must there subsist on some alternative foodplant.
