The third paper of Mr. Beyerink will probably be useful to Amer- 
ican students, as the galls produced on our Crucifere will be found 
nearly related to those of Kurope. Mr. Beyerink describes four 
fungi as producers of hypereropthis: four Diptera, three of them 
Cecidomyia, and one Agromyza doubtful; one Hemipteron, the well 
known Aphrophora spumaria; five Coleoptera, all weevils; and some 
Phytoptus. 
It is of course impossible to give an extract of the condensed rec- 
ord of Dr. Thomas, but for American Entomologists, it will be of 
interest to know that the new genus Colopha (Thelaxes ulmicola 
Walsh) of Mr. J. Monell, Canad. Entom., vol. rx, is identitied as the 
common European species Tetraneura ulmi. 
Prof. O. Nickerl has published a record of the insects observed to 
be obnoxious to farmers in Bohemia, during the year 1878. There 
are two facts probably of some value for N. American farmers. The 
sugar beet is extensively damaged by larvae of different species of 
Silpha. These larvae are commonly considered to be carrion-teeding, 
but it was shown by experimenting, that though not avoiding meat 
or carrion, they will leave this kind of food when plants are at hand. 
Farther experiment showed that some weeds were preferred by the 
larvae to the sugar beet. ‘Therefore Mr. Nickerl recommends farm- 
ers not to clear the fields entirely of these weeds. As two of them, 
Chenopodium album and Atriplex platula, are very common here, it is 
possible that they would here in the same manner be attractive to 
obnoxious larvae. 
Farther it was observed that many injurious moths, principally 
those with hairy caterpillars, have the habit of depositing the eggs 
in the interior of bird-houses. Therefore it is recommended to clear 
such houses carefully before the spring. I may remark that in Ger- 
many such cleaning is done regularly, as it has been observed that 
birds avoid the uncleaned houses. 
Note on A SARCOPHAGOUS LARVA FOUND IN A GrRw’s NECK. 
By Dr. H. A. HAGEN. 
T lately received from Mr. R. R. Wright of Toronto, Canada, the 
skin of a larva extracted from a swelling in the neck of a girl. 
The larva belongs to the genus Sarcophaga, and there are known 
at least seven cases, where sarcophagous larvae have been extracted 
living from the eyes, nose and ears of man. Mr. J. F. Ruthe-
