mological Society. In the first published account of this exhibi¬ 
tion (II) it is stated that the larvae were in flour shipped from 
America to Trieste, and thence to London; but later (20) Prof. 
Cockerell states that although the larvae just referred to were 
in flour from America, they were supposed to have come from 
some badly infested Trieste flour stored in the same warehouse. 
In the same year Mr. C. G. Barrett (12) reports breeding 
moths of Ephestia kuehniella from larvae sent him by Prof. 
Zeller in 1879; refers to the moths of this species sent him by 
Mr. Thompson for determination, noted above; and briefly de¬ 
scribes the moth, noting ready means of distinguishing it from 
that of other species of Ephestia and from Myelois ceratonice. 
November 2, 1887, Mr. Sidney T. Klein read notes of his ob¬ 
servations on the habits of Ephestici kuehniella , at a meeting of 
the Entomological Society of London (13). He discovered in 
May a colony of these larvae in some large warehouses in the 
east end of London, where the insect spread rapidly in spite of 
the fact that the building was fumigated with sulphur and the 
ceilings, walls, and floors were hot-limed. One entire warehouse 
was “literally smothered with larvae, and several hundred pounds’ 
worth of damage was done.” Chickens introduced into the ware¬ 
house gorged themselves with the larvae. Some interesting ob¬ 
servations are reported concerning the habits of the larva, and it 
is said that a small hymenopterous parasite ( Bracon brevicornis 
Wesm.) destroyed the pest by September. The same author 
gives elsewhere (14) full details concerning a lot of flour from 
Trieste infested with larvae of the flour moth, referring, again to 
the parasite, and in another connection (15) has an item con¬ 
cerning the introduction of the flour moth into England. The 
County of Middlesex Natural History and Science Society pub¬ 
lished a note by Mr. Archibald Geikie (17), in which he reported 
the complete destruction of Ephestia kuehniella by the same 
little braconid mentioned by Mr. Klein, figuring the male and 
female. He said, in substance, that he had noticed a black spot 
on the back of the flour moth larvae which he had not observed 
before, but paid no attention to it, thinking it a normal phenom¬ 
enon in the development of the insect. Some weeks later he was 
astonished to find on the sacks of flour, which had been covered 
with Ephestia larvae, a great number of little black insects, and he 
was of the opinion that the black spots he had seen were noth¬ 
ing else than the eggs of Bracon brevicornis. 
I will not call in question the correctness of this inference, as I 
know nothing about the life history of the European braconids, 
but will simply say in this connection that our two American 
species, Bracon gelechice Ashm. and B. hebetor Say, do not lay 
their eggs within the body of their host. I have made many 
observations on this point, and have always found the egg either 
on the bodv of the larva or attached to some material very near 
it. Mr. E. B. Poulton, of London, England, has, however, shown 
by experiment ( 21 ) that these black spots are simply testicles 
in the process of evolution. Mr. J. Danysz, of Paris, France, 
who seems to have overlooked Mr. Poulton’s paper, has arrived
