It was not uncommon in the cool woods along the outlet of 

 tile lake. 



IS. Limnophila (Dactylolabis) montana O. S. 



On May 16, 1907, I found this species very abundant around 

 a stone quarry near the Gloversville Reservoir. The flies lurked 

 in the crevices of the rocks and large numbers were collected 

 as they hung inverted from the roof of the crannies. This is 

 the only Limnophila that I have taken in such a situation. 

 (This is mentioned in Needham's list, qvioted before.) 



19. Hexatoma megacera O. S. 



This remarkable little species was not at all rare on .Sport 

 Island, Sacandaga R., June 6, 1909. It occurred on semi- 

 palustral grasses along the northeast coast of the island and 

 along the "bayou." It was very sluggish and not at all diffi- 

 cult to capture. A large number were secured. 



20. Eriocera longicornis Walker. 



Of this remarkable species I secured a single male specimen 

 on May 18, 1907, flying at twilight over a grassy field near 

 Gloversville, N. Y. On June 6, 1909, it occurred in large num- 

 bers on Sport Island, Sacandaga River. In the late afternoon 

 a few scattered individuals were observed. Just after sunset 

 the insect became very abundant along the north end of the 

 island, hovering in small swarms over the water's edge and 

 dancing about like many of our smaller Tipulids. Toward 

 dusk, many species of may-flies and caddice-flies joined the 

 little companies of dancing flies. Of the specimens secured, 

 the males slightly predominated in numbers. 



L'l. Tricyphona (Amalopis) inconstans O. S. 



Canada Lake (Caroga township), July 10, 1909, two speci- 

 mens. Not at all rare about Woodworth's Lake in August. 

 Johnstown, N. Y., in June, July, August and, especially, early 

 September. 



22. Liogma nodicornis O. S. 



Mountain Lake Bog Pond (Johnstown township), altitude 

 1,585 feet, June 26, 1909. It was very common toward sunset
