life history of Trypeta fratria Loew, which may be called the parsnip 
leaf-miner. 
On June 11, 1891, Dr. Riley received, a package of parsnip leaves 
from Mr. J. Gr. Barlow, of Cadet, Mo. These had been quite exten- 
sively mined by the larvae of a two-winged fly, aDd from three pupa- 
ria found in one of the mines the adults issued on the 23d of the 
same month. These belong to Trypeta fratria, a rather rare species, 
which extends from the Atlantic seaboard westward at least as far as 
the State of Missouri. Dr. Loew, who has published a monograph on 
this group of insects, has expressed the opinion that one of the forms 
described from California by the Swedish entomologist, Thompson, may 
prove to be identical with the present species, in which event its distri- 
bution would be extended across the continent. 
The European species belonging to the same group or subgenus 
(Acidia) as this one, are principally leaf-miners in the larva state, and 
the nearest related species {Trypeta lieraclei Linn.) has been bred from 
larvae found mining the leaves of Eumex, Heracleum, Ligusticum, 
Archangelica, and the common garden celery. Several of these plants 
belong to the same natural family as the parsnip. 
The remedies mentioned as of value against the radish leaf-miner 
will be equally applicable to the present species. 
SOME COLEOPTEROUS ENEMIES OF THE GRAPE-VINE. 
By F. H. Chittenden. 
In the Eeport of the Nebraska State Horticultural Society for 1895 
Mr. Lawrence Bruner gives a list of thirty- six species of Coleoptera 
affecting the grape-vine. Deducting three synonyms, this leaves a total 
of thirty- three species. Mr. Bruner has made no pretensions to a com- 
plete list of grape vine insects, nor is it my intention to more than 
supplement his list by adding such species as I recall from personal 
observation, and such as are specifically mentioned in literature or 
in the records of this division as attacking the vine in this country. 
The twig-pruner (Elaphidion villosum~Fai>b.) is of common occurrence, 
in my experience, on grape. I have in mind at least two published 
statements of this food habit, viz, that by Professor Riley (Am. Ent., 
vol. in, p. 239), and my own (Pr. Ent. Soc. Wash., vol. in, p. 96). 
Xeoclytus erythrocephalus Fab. is recorded from grape (loc. cit., p. 97). 
The red-legged flea-beetle (Crepidodera ruftpes Linn.), attacks the 
opening leaf buds of grape, and is capable, if present in sufficient 
numbers, of very serious damage. During May of last year I observed 
this bud-destroying habit near Washington, and we have a divisional 
record of having received the same insect May 13, 1881, from Mr. 
Eandall Morton, of Pittsburg, Pa., with the statement that the species
