VOL. XXI. OCTOBER, 1914, No. 5
LIST OF THE HEMIPTERA-HETEROPTERA OF MAINE.' BY H. M. PARSHLEY,
Bussey Institution, Harvard University.
The present list is the first of a series of papers in preparation by me on the Heteroptera of New England and is offered as a record of the species definitely known to inhabit Maine. In view of the great extent of almost inaccessible territory in the state and the relatively small amount of collecting which has been done, it is to be expected that additional species will be found, but I hope that the list is complete enough to be a useful basis for sub- sequent work, as it includes records of 176 species. The records have been compiled chiefly from the following sources: An unpublished list of Maine Hemiptera by Mr. 0. 0. Stover, whose material was determined in part by Uhler, in part by Professor Osborn; the collection of the Maine Agricultural Experiment Station, determined largely by Mr. E. P. Van Duzee; the collection of Mr. F. A. Eddy of Bangor; the collection of the Boston Society of Natural History; and my own collection. The dates given are the earliest and latest which I have found on record for the several species.
My thanks are due the following, who have lent me their assist- ance; Dr. Edith M. Patch, who has put the collections and records of the Experiment Station at my disposal; Mr. J. R. de la Torre Bueno, who has determined a number oi specimens and given valuable suggestions; Mr. F. A. Eddy, the veteran collector of Maine, who has permitted the free use of his valuable collection; Mr. C. W. Johnson, who has given me access to the cdlection of the Boston Society of Natural History; Mr. 0. 0. Stover, who has generously allowed me to make use of his unpublished records; and Mr. C. A. Frost, who has given me specimens of several species which otherwise would not have been recorded. 1 Papers from the Maine Agricultural Experiment Station: Entomology No. 74.

I took twelve specimens of this species as they flew up, one by one, to the dried body of a long dead fowl. Some alighted nearby and others disappeared within the carcass.
I was unable to determine whether they came to feed on the juices of the carrion or to prey on other insects, and they may have been attracted merely by the odor. I believe that there are few if any so positive records of the frequenting of carrion by Heteroptera.
