1929] 
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 grossularise 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 Syrphidae including the type of 
T emmostoma excentricum 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 guava” There are also specimens of Chryso- 
toxum perplexum John., Sphserophoria cylindrica Say., Helo- 
philu latifrons Loew, Criorhina verbosa Walk., and Spilo- 
myia fusca Loew.
