NOTES ON THE SYRPHIDAE COLLECTED AT
JAFFREY AND MOUNT MONADNOCK, N. H.,
WITH A DESCRIPTION OF A NEW SPECIES
BY CHARLES W. JOHNSON
Boston Society of Natural History
My first visits to Jaffrey and Mt. Monadnock, N. H., were made in February and March, 1917.
Even with the deep
snow covering the beautiful woodland and mountain, one could readily see that this would be an ideal place for col- lecting. June, 1917, was therefore selected for another two weeks visit. Arriving on the 15th, the flowers of the choke cherry were just opening and for four days I caught hundreds of syrphids and other insects on these blossoms. Later the flowers of a Cornus followed by those of a Vi- burnum attracted many other species. Among the speci- mens obtained were about seventy species of Syrphidse. In 1920 another visit was made, this time covering a period from June 4th to 14th. In the depression back of the old red school house some timber had recently been cut and from the stumps of sugar maple and birch sap was still flowing freely, the fermented sap containing many larvae from which were bred Ferdinandea dives and Brachyopa perplexa. The Cornus bushes were mostly dead, probably winter killed by the severe cold of January, 1918. My next visit was in 1923, staying from June 14th to the 23rd. A few rainy days had made the cherry blossoms poor col- lecting ground but this loss was somewhat made up by the flowers of the raspberry which had grown up on the clear- ing back of the old red school house, species of Criorhina and Xylota being especially common. My next visit cover- ing a period from May 9th to 21st, 1925, was perhaps the most interesting. To see the various spring species appear one after the other was a very enjoyable experience. An old oak log along the brook near "The Ark" was visited daily from the 14th to the 21st to secure the two species of

19291 Syrphidae Collected at New Hampshire 371 Chalcomyia. The last of my June trips was in 1926 from the 5th to the 18th.
It is interesting to note how seasons and conditions change in different years in this fascinating place. I was not able to duplicate the great catch I made in June, 1917, on the flowers of the choke cherry, neither have I been able to find so much sap flowing from stumps as in 1920, nor another oak log frequented by the two species of Chalcomyia. The area covered in collecting extends from the Shattuck Inn to about 1700 feet on Mt. Monadnock and from Mead's Brook to Hadley Brook, an area of about two square miles. A few trips were made to the top of the mountain (3166 ft.) but no additional species were taken, all those on the bare rocks of the summit being probably derived from lower levels. With "The Ark", where I stayed, as a center, I doubt if there is a corresponding area that would produce as many Syrphidse in the time mentioned. Of the 113 species recorded below, six were new to science. In addi- tion to these a great many other insects were also collected. Microdon ocellaris Curr. June 20, 1923.

19291 Syrphidae Collected at New Hampshire 375 An autumn trip to Jaffrey (Oct. 2nd to 16th, 1929) yielded comparatively few insects. Among these, however, were twenty species of Syrphidae of which the following are not in the above list: Syrphus wiedemanni John. Epis- trophe grossularias Meig. and Toxomerus marginatus Say. This region has entomologically speaking, an interesting history from the fact that the earliest collection of insects made in the state were found here. These were collected by the Rev. L. W. Leonard of Dublin, N. H., between 1828 and 1835. The specimens are now in the Harris collection, in the Boston Society of Natural History. In referring to Mr. Leonard's work Dr. T. W. Harris, in a letter to Hentz dated Milton, [Mass.] June 17, 1828, says: "My friend, Mr. Leonard has promised to send me a quantity of duplicates from his parish in Dublin, N. H. near the Grand Monodnoc Mountain. Many among those which I have already received from him are entirely new to me. Mr. Leonard is indefatigable in studying the habits of in- sects and very successful in raising them from the larvae. Through him I have ascertained the larvae of many, species in my collection and particularly of the Lepidoptera." In Hitchcock's Report on the Geology, Botany and Zology of Massachusetts, 1835, in the notes, page 601, Dr. Harris says: "I have included in the catalogue some insects which, though found beyond the boundaries of the State, may eventually be detected in Massachusetts. For these, and an immense number of duplicates, I am indebted to my friend the Rev. L. W. Leonard of Dublin, N. H., who has still more increased my obligations to him by his disin- terested liberality in sending me even the rare and unde- scribed insects of which he possessed no duplicates." In the material collected by Rev. L. W. Leonard are a number of interesting Syrphidse including the type of Temmostoma excentricurn Harr., and a specimen of Cri- orhina intermedia John., collected May 1832, which had .
been sent to Say by Harris in 1833 and given the manuscript name "Milesia gnava." There are also specimens of Chryso- toxum perplexum John., Sphasrophoria cylindrica Say., Helo- philu latifrons Loew, Criorhina verbosa Walk., and Spilo- myia fusca Loew.
