THE CANADIAN ENTOMOLOGIST. 117 



C, pallidipes is the commonest species of the genus in central 

 Ontario, usually occurring under chunks and small logs in woods. On 

 Aug. 8, 1904, I found them in some numbers on the slope of one of the 

 Rosedale ravines at Toronto, but the area over which they occurred was 

 limited to a few acres. There were two or three or more individuals 

 under nearly every chunk of wood, most of them mature. At De Grassi 

 Point, Lake Simcoe, I have occasionally taken them in rotten sodden 

 logs. In one such log seven adults were found together. 



As is commonly the case in Ceuthophilus, the young nymphs may be 

 found at any time in the year, for although most of them mature in the 

 summer from eggs hatched in the spring, a few pass the winter as young 

 nym[)hs, the eggs not having hatched until the fall. They usually reach 

 maturity about the first or second week in July, and continue until the 

 second week in September.

I have but one pair of this species, about half grown, taken from 

 under a stone at Niagara Glen, Aug. 18, 1904. A number of very young 

 individuals were also found with them. They were kindly determined for 

 me by Mr. A. P. Morse, who compared them with material in the Scudder 

 collection. I was afterwards able to confirm his determination. 



C. neglectus is an eastern species, ranging from Vermont and 

 Northern New York to Virginia. 



Figs. 3, 3a, PI. 5, were drawn from one of Scudder's type specimens. 

 Figs. 3b, 3c are from my immature male, and probably do not exactly 

 represent the form of the subgenital plate in the adult.
