REPORT OF “THE ENTOMOLOGIST. = =. «93, 
the silk threads and the excrement which filled the injured nuts. 
Te orifice in the hilum of the nuts was also produced by these cater- 
pillars in the act of leaving the fruit to transform outside. 
«But there was also, besides the two caterpillars, a great number of 
_ reddish maroon pups, which could only belong toa dipterous insect. 
- These were found everywhere in the cavity of the spoiled nuts. At 
the end of two weeks there issued a number of small black flies. 
These all belonged to the same species (Siphonella nucis) which M. 
__E. Perris made known for the first time in our Annales more than 
- thirty years ago, accompanying his work by numerous figures. 
_  ©T have not seen the larve of the Siphonella, but M. Charles Robin 
has seen them inthe wormy nuts. These larve transformed to pupze 
during the journey from the Department of the Ain to Paris. 
**T confided to the care of M. J. Fallou the two caterpillars 
- mentioned. One of them after pupating produced Carpocapsa po- 
/ monana. 
> «* * * Tn my opinion the larva of Siphonella nucis lives upon 
- spoiled material, perhaps upon the excrement of other larve, and 
» is not to be relegated to the same rank as the Carpocapsa for the dam- 
age which it causes. M. Perris has distinctly stated that it is nota 
_” parasite; it lives by the damage done by the Carpocapsa, which is in 
- reality the principal author of the injuries which render the nuts 
--worm-eaten.” 
q _ The fact that this insect was a true Codling Moth rests entirely 
~ upon the determination of Mr. Fallou. Onreferring to the bulletin 
_ of the same society for December 27, 1871, page 85, we find that La- 
% boulbéne stated that the specimen bred by Mr. Fallou was destroyed 
_. during the sack of the city of Chateaudun by the German army. In 
speaking of it he makes use of the following somewhat significant 
. sentences: ‘* This Lepidopter was so near Carpocapsa pomonana, 
Hiibner ( pomonella, L.), that it was referred to thisspecies. However, 
to make sure,-Mr. Fallou sent it to Mr. Guenée, who is so great an 
authority upon such matters. We know what became of the speci- 
men. In order to state positively that the lepidopterous insect inju- 
rious to walnuts is the same as that which injures our apples it will 
be necessary to raise a great number and so determine it irrefutably. 
I call this fact to the attention of competent entomologists.” 
a Even in this state of comparative doubt, however, the fact seems . 
to have been accepted by other entomologists. The record is quoted 
~ without question in the Zoélogical Record for 1871, page 580. 
In the Entomologist’s Monthly Magazine, Vol. XV (1874), page 
18, Mr. C. G. Barret states that Mr. W. West “tells him that he has 
‘reared the perfect insect [C. pomonella] from a larva which he found 
_ feeding ina walnut. Without intending aslur upon Mr. West’s com- 
_  petency, we may simply draw attention to the fact that this determi- 
» nation does not seem to have been verified by any well-known ento- 
mologist. 
_ Inthe bulletin of the Societé Entomologique de France for May 
10, 1876, Mr. Ragonot makes the similar statement that this insect 
has been reared from walnuts, although he does not give it asa per- 
sonal observation, and it is probably simply a reference to Mr. Fal- 
lou’s rearing, 
The probability of a uniformity of habit in this species must be 
~ our excuse for endeavoring to show that these observations are not 
well supported, and we may refer to the fact that a closely allied 
Species (Carpocapsa putaminana, Staud.) seems to be quite well
