THE CANADIAN ENTOMOLOGIST. 125 



Regina and Indian Head are in the Eastern part of Assiniboia, about 

 the middle of the great wheat belt. 



Medicine Hat is in the Western end of the same Province. 



Lethbridge, Macleod and Pincher are just above the United States 

 line in the Southern end of Alberta. 



St. Albert is the Northern terminus of the Calgary and Strathcona 

 (Edmonton) branch of the C. P. R., and nearly the Northern end of 

 Alberta. 



Pine Creek is in Alberta, between Macleod and St. Albert. 



From the apparent topography, I assume all of the Assiniboia locali- 

 ties are in the great stretch of prairie land, which likely partially con- 

 tinues into the Eastern half of Alberta ; Pincher and Pine Creek are in the 

 lower foot-hills, and St. Albert in the vast forest and lake districts of the 

 Northwest. 



THE GENUS VENUSIA AND ITS INCLUDED SPECIES. 



BY RICHARD F. PEARSALL, BROOKLYN, N. Y. 



If it were necessary to emphasize the need of revision in the 

 Geometrina, the genus Venusia furnishes an excellent example. It was 

 established by Curtis, an English writer, in 1839, with cambrica. Curt., as 

 its type. Since that time, three additional species, according to Mr. 

 Meyrick, from New Zealand have been placed under it. In our own 

 fauna. Dr. Hulst placed three species as its representatives — cambrica, 

 Curt., compiaria. Walk., duodeciin/ineata, Pack. Cambrica, the type, has 

 a world-wide distribution. It flies in England, in Northern Europe, across 

 Northern Asia, in Japan, and in the north temperate zone of America. 

 Coniptaria is found in Canada, the mountainous regions of New England 

 and New York, and along the Appalachian range as for south as Pennsyl- 

 vania and probably farther ; diiodecimlineata comes from northern Cali- 

 tornia, and with it, under this name, have been associated examples taken 

 in British Columbia; and another series found in the East, ranging from 

 the vicinity of New York City, southward into Pennsylvania and probably 

 into the hill regions beyond. During many years collecting in the 

 Catskill Mountain region, I have never taken it there, while cambrica and 

 comptaria were abundant. 



Briefly, 1 will state that the chief distinguishing character of Venusia, 

 is the bipectinate antennae of the males. In the group I have mentioned, 

 cambrica is the only species possessing this structure, and it is my opinion, 

 that here, as in Europe, it is the sole representative of its genus. Coinp-
