life history of Trypeta fratrla Loew, which may be jailed the parsnip 

 leaf-miner. 



On June 11, ISOl, I)r. Riley received a package of parsnip leaves 

 from Mr, J. G. Barlow, of Cadet, Mo. These had been quite exten- 

 sively mined by the larvie of a two-winged fly, and from three pupa- 

 ria found in one of the mines tlie adults issued on the 23d of the 

 same month. These belong- to Trj/peta 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 

 tliis group of insects, has expressed the opinion that one of the forms 

 described from California by the Swedish entomologist, Thompson, may 

 l)rove 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 Jicraclei Linn,) has been bred from 

 lavvne found mining the leaves of Rumex, Heracleum. Ligusticum, 

 Archangelica, and the common garden celerj^ 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 api)licable to the present species. 



SOME COLEOPTEROUS ENEMIES OF THE GRAPE-VINE. 



By .F. H. Chittenden. 



In the Report 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 specilically mentioned in literature or 

 in the records of this division as attacking the vine in this country. 



The twig-pruner {Elapliidion villosuniFixh.) 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. Ill, p. 239), and my own (Pr. Ent. Soc. Wash., vol. iii, p. 90). 



Xeodytus erythrocephalus Fab. is recorded from grape (loc. cit., p. 97). 



The red-legged flea-beetle {Crepidodera rujipes Linn.), attacks the 

 opening leaf buds of grape, and is capable, if present in suflicient 

 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 Mny 13, 188 L, from Mr. 

 Randall JNIortou, of Pittsburg, Pa,, with the statement that the species
