ENTOMOLOGICAL SOCIETY OF ONTARIO. 115 



While we deplore Dr. Eiley's resignation, we cannot refrain from expressing our 

 gratification at the appointment of his successor. The authorities at Washington have 

 shown their wisdom in conferring the vacant office upon Mr. L. O. Howard, who has been 

 so long and so ably sharing in its duties as First Assistant. The Department is certainly 

 to be congratulated upon having at hand a skilled and learned entomologist who pos- 

 sesses in every respect the varied qualifications necessary for the successful performance 

 of so important an office. We have every confidence that the world-wide reputation now 

 possessed by the Division of Entomology at Washington will be in no wise impaired 

 under the administration of Mr. Howard, and we heartily wish him health, strength, and 

 a long life for the successful performance of his arduous and important duties. — C.J.S.B , 

 Canadian Entomologist, June, 1894.

The Butterflies of North America : By W. H. Edwards. Third Series. Part 

 XIII. 



Anoiher part of Mr. Edwards's magnificent work has been received, and is of 

 particular interest to Canadian students. The three beautiful plates represent the 

 following : Plate I., Xeominois Ridingsii, Edw. The upper and lower sides of both 

 sexes of ti e early and late forms are shown, together with the egg and pupa, and a full 

 series of enlarged drawings illustrating the larva in all its stages. This is a Coloradan 

 insect, and flips in the mountains at an elevation of from 5,000 to 8,000 feet. Up to 

 the present there is no recorded instance of X. Rldingsii having been taken in Canada. 



Plate II. shows Chionohas ^Eao, Bdl., male and female, and a variety of the male, as 

 well as Ch. ^Eno, var. Assimilis, Butler, and the egg of Crambis, Freyer. ^Erio is an arctic 

 species occurring with the variety in Labrador, and also in Colorado where it inhabits the 

 loftiest mountain peaks. An interesting account of its habits is given from the notes of 

 Mr. David Bruce, who has done a great deal to work up the life-histories of the buttertiies 

 of the Coloradan mountains. -Eno belongs to the Semidea group of the genus, and has 

 been confounded with that species and Crambis, Freyer. Mr. Edwards says : " It was 

 not till Mr. Bruce explored the peaks of Colorado that it became passible to understand 

 what ^Eao was, and the limitation of Brucei made clear the position of Crambis." 



The series is now arranged as follows : 



1. Crambis, Freyer. 



2. Brucei, Edw. 



3. .Eno, Bdl. 



var. AssiMiLis, Butler. 



4. Semidea. 



5. subhyalina. 



Ch. Also, Bdl., Mr. Edwards rejects altogether as an American species. 



Plate III. shows Ch. JfaanmH, the grand species which was discover«!d at Nepigon. 

 north of Lake Superior, by Pi of. John Macoun, of the Geological Survej', in whose honor 

 it was named. Ch. Macounii belongs to a different group of the genus to the species 

 mentioned above, and finds its place with CaJifornica and some other large species occur- 

 ring on the Pacific Coast. It is a fine insect expanding 2-2^1 inches and has the remark- 

 able feature of lacking the sexual band of androconia or special scales, which is such a 

 striking characteristic of the males of all the other species in the genus. The plate is a 

 very beautiful one. and shows a pale male and the full life-history with the exception of 

 the pupa. The female figured, although of course copied from an actual specimen, is
