as given below, were observed flying 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). Massachusetts, 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). New Jersey, Warren Co., Delaware Water Gap, 

 July 4, 1898 (Johnson). 



Eriocera spinosa Osten Sacken. 



Arrhenica spinosa Osten Sacken; Proc. Acad. Nat. Sci. Phila.,

Messrs. Rich and Ellis, while collecting Corydalis larvae 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 larvae 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) ; 

 Little 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
