THE CANADIAN ENTOMOLOGIST. 105 



Ravine — the only butterfly seen there ; both had probably flown in from 

 below. 



A few fresh specimens of Pieris rapce were seen every day but the 

 first j most on the last day, below Emery's. 



Six or eight specimens of P. oleracea were seen, all very fresh j of the 

 three or four taken only one was a female. 



T\voyx^ Euphoeades turnns was seen every day in very fresh condition, 

 it was not yet abundant ; four, however, were seen at one roadside pud- 

 dle, and all were exceedingly tame. 



Several fresh specimens of Thanaos icelus were seen the first day and 

 the numbers increased daily, both sexes fresh, but the female predomin- 

 ating. Several females were enclosed on different species of poplar and 

 willow, but laid no eggs. 



Two male specimens of Cyclopides inandan were taken by the road- 

 side on the 5th, and one or two were seen north of Emery's on the 7th. 



Males and females of Amblyscu'tes vialis were seen every day, but 

 never more than three or four specimens a day. Enclosed females laid 

 eggs on grass on June 5-6, which began to hatch on June 14; the first one 

 to change stopped eating on July 18 or 19, and in about ten days changed 

 to chrysalis. The species has never before been reported from this region. 



A couple of specimens of Amblyscirtes samoset were seen, and one of 

 them taken on the 7th, north of Emery's. 



The first Atrytone hobomok was seen on the 7th, in the Glen, another 

 between that and Emery's ; but south of that at least a dozen specimens, 

 all of them males. 



Pamphila sassacus first appeared at Emery's, south of which it was 

 twice as abundant as the last species ; a couple of females were taken, but 

 nearly all the others seen ^yere males. It was evidently going to be very 

 abundant. 



SYNONYMY IN AMERICAN COLEOPTEROLOGY. 



BY JOHN HAMILTON, M. D., ALLEGHENY, PA. 



On looking over Melsheimer's, Crotch's and Henshaw's Catalogues of 

 the described species of North American Coleoptera, many names will be 

 seen placed as synonymical, or varietal ; while a reference to the 

 bibliography of the many synopses and monographs of families and gen-
