The earliest larva taken in New Jersey was by Mr. Brehme, 

 at Hemlock Falls, June 20th. Mr. Grossbeck found it next, in 

 a large woodland pool with partly rocky bottom, on the Garret 

 Mountain, near Paterson. June 30th Mr. Brehme sent in larvae 

 taken from the South Orange Mountain, from which adults were 

 obtained July 2d and 3d. July 15th larva; occurred on the Col- 

 lege Farm and near the old copper mines at Arlington. August 

 8th there was another brood on at the College Farm, and on the 

 15th others were taken at Livingston Park. During this month 

 Mr. Grossbeck found the adults in the Great Piece Meadow, and 

 during September he found large numbers of larvae in the wood- 

 land pools there and in the Troy Meadows. As late as Septem- 

 ber 30th he collected the larvae in numbers, full grown and ready 

 for the change. Pupation began October ist, and the first adult 

 occurred October 4th. Development during the summer is verv 

 rapid ; but in late fall it becomes much slower. 



Altogether, while this species is sometimes common and bites 

 hard, it can scarcelv be considered a pestiferous species, because 

 it does not leave the woods and breeds only in such swampy 

 areas as are not often visited.
