as given below, were obserxed Hying rapidly over the creek-bed of 
a mountain stream in the dense shade of the forest. The known 
distribution of the insect so far as known is as follows: New 
Hampshire, White Mts., Osten Sacken's type; Bretton Woods, June 
27, 1913 (Johnson). Massachiisells, Hampden Co., Chester, Aug. 
7, 1912 (Johnson). Nezv York, Erie Co., South Wales, July 9, 
1911 (Van Duzee) ; Herkimer Co., Old Forge, July 12 to 16, 1905 
(Needham) ; Fulton Co., Pinnacle Mt., alt. 2000 feet, Aug. 4, 1914 
(Alexander). Nciv Jersey, Warren Co., Delaware Water Gap, 
July 4, 1898 (Johnson). 
Eriocera spinosa Osten Sacken. 
Arrhenica sphwsa Osten Sacken; Proc. Acad. Nat. Sci. Phila., 
244, 1859. 
Messrs. Rich and Ellis, while collecting Corydalis larvs in Fall 
Creek, Ithaca, N. Y., on Oct. 31, 1914, report the finding in im- 
mense numbers of large, almost fully-grown larvae of this species. 
They formed a high percentage of all the insect life noted in the 
rapid water. The observations made earlier by Alexander and 
Lloyd concerning the carnivorous habits of these larvae were con- 
firmed by Mr. Rich who placed the larvas in dishes together with 
nymphs of various Odonata, the smaller ones of which were eaten 
by the Eriocera larvae. 
Eriocera longicornis Walker. 
Anisomera longicornis Walker; List Dipt. Prit. Mus.; 1, 82, 
1848. 
This well-known species was discussed in some detail in the paper 
on Eriocera cited before. Many specimens of larvze and pupae have 
been taken and it seems probable that the larva described in that 
paper is not typical of longicornis. It is preferred to await more 
data before saying anything further about the insect. The distribu- 
tion as indicated by my sheets is quite extensive being as follows : 
Canada, Ontario, Nagagami R., June 20-21, 1903 (W. L. Wilson) ; 
Litde Current R., July 8, 1903 (Wilson) . Maine, reported by John- 
son. Massachusetts, collected by Packard. New Hampshire, Bretton 
Woods, June 24-25, 1913 (Johnson). Connecticut, New Haven
