THE CANADIAN ENTOMOLOGIST. 131 



Described from 21 males and 20 females in the New Jersey 

 Experiment Station collection. 



Habitat : Livingston Park (near New Brimswick), N. J., and West- 

 ville, N. J. 



This species was first taken in New Jersey, near Paterson, in April, 

 1903, in the larval condition ; but no adults were bred therefrom. In 

 the following spring they were again met with in Ivivingston Park, and in 

 the season of 1905 they were secured from this locality in s'ome numbers. 

 They were found full-grown as early as April 28th — indicating an egg 

 hibernation — and the last were taken not later than May 17th, though 

 frequent subsequent collections vvere made. No larvse were ever taken in 

 any but fresh water, woodland pools ; and adults were never seen outside 

 their immediate breeding grounds. After emergence they continue on the 

 wing for a period of about three months, becoming more and more worn 

 as the season advances. 



An account of the life-history of this species as far as known, and a 

 description of both larva and adult, is given by Prof. Smith in his "Report 

 on Mosquitoes'' (N. J. State Exper. Sta., 1903-04), and also a description 

 of the larva in Psyche, Vol. XII> p. 13. 



A description of the genitalia of C. squauiiger is here appended for 

 comparison with C. sylvicola (Fig. 11): Clasp elongate, margins sub- 

 parallel almost to apex, inner margin rounding abruptly toward apex ; 

 subapical lobe setose ; basal lobe well developed, setose, a long spine 

 recurved at the tip arising near it, another stout spine a short distance 



above this ; clasp filament long, cm ved, four small setae near the apex, 

 with long apical spine. Haipe jointed, basal segment comparatively short, 

 apical segment short, dilated centrally, tip slightly curved. Harpago 

 hood-shaped, tip bent laterally. Appendage of eighth segment with short 

 setae. 



THE ACADEMY OF SCIENCE OF ST. LOUIS. 



This institution, founded in 1856, celebrated its first jubilee by a 

 dinner on Saturday evening, March roth. About 200 persons were 

 present, including a number of representatives of societies at a distance. 

 The Entomological Society of Ontario was well represented by one of its 

 ex-presidents, Prof Lochhead, of Guelph, who conveyed the cordial 

 greetings of this Society to the members of the Academy. In com- 

 memoration of the interesting event a handsome bronze medal has been 

 prepared, having on the obverse a portrait of George Engelmann, the 

 first president. 'I'he Curator desires to express his hearty thanks for the 

 one presented to our Society.
