THE CANADIAN ENTOMOLOGIST. 277 



Mr, A. D. Hopkins, Entomologist of the West Virginia Agricultural Ex- 

 periment Station, to whom one of the Canadian examples was submitted 

 for comparison, kindly states that there is *' little perceptible difference " 

 between it and that named longiceps for him by Dr. Riley through the 

 National Museum. In the seven examples seen no sexual differences are 

 observable in the head or abdomen. I have examples of a species 

 occurring in the White Mountains of New Hampshire, which is quite 

 different, having a very large head, especially the o* • It nas received the 

 name macrocephalus, Nord, but from which it differs by not having 

 the 6th ventral segment of the $ emarginate and the thorax tri- 

 punctate (Mannerheim's description). I have two female examples 

 from Alaska — one from Wrangel with the thorax tripunctate {macro- 

 cephalus) agreeing in every other essential point with the New 

 Hampshire females ; and one from Prince of Wales Island, with the 

 thorax bipunctate, entirely pallid, and .15 inch long, but otherwise agree- 

 ing with the Wrangel example ; more material, however, must be seen be- 

 fore their identity can be assured. Thus it appears there are at least 

 three distinct species of Baptolinus inhabiting North America, whatever 

 may be said of names. This is the species mentioned as pi/icoruis in Can. 

 Ent., XXIV, 293, but more material shows that the head is smaller than 

 in that species, the description of which otherwise is fairly applicable ; 

 and it is in many ways different from the New Hampshire species. In 

 the article referred to, read (Rev. Entomol., VIII, 117)., B. longiceps, 

 Fauv., instead of as in lines 28-29. Mr. F. Blanchard mentions (in litt) 

 an example with the head scarcely punctured, taken by him in North 

 Carolina, which probably belongs here. 



Dicerca, sp. Two examples, $ and $ , were taken in the lake, which 

 seem to be nondescript ; in size and sculpture they resemble Chrysea, 

 Mels., to which they were about to be referred till the terminal ventral 

 segment of the $ was observed to be rounded ; the same segment of the 

 o* is truncate and rectangularly emarginate, and the middle tibia toothed. 

 Other examples were subsequently seen in another collection, and it is 

 possibly confused in northern cabinets with chrysea, from which it seems 

 best separated by the sexual characters of the female. 



Aphodius leopardus, Horn. This species occurred in some abund- 

 ance, as it likewise did at Parry Sound on the Georgian Bay, and at inter- 

 mediate points. It was not taken with the other species about cow-yards, 

 but on paths through the forest, Before the introduction of domestic
