94 THE CANADIAN ENTOMOLOGIST. 



PREPTOS, TAMPHANA, AND AROTROS. 

 In the February number of the Canadian Entomologist, Mr. Dyar 

 very justly complains of the inadequacy of my descriptions of the above 

 genera in the Proceedings of the Zoological Society of London, for 1892. 

 Both Preptos and Tamphana belong to the Eupterotidae. Preptos is 

 most closely allied to the Eastern genus Tagora, Walk., and differs in the 

 following particulars : — Primaries with veins 5 and 6 from upper angle of 

 cell, discocellulars angled outwardly and then inwardly close below vein 

 5 ; secondaries with discocellulars very oblique. No allied forms of 

 Preptos oropus have as yet been discovered in America, although the 

 species has been redescribed as Tagora cor ax. Druce, Proc. Zool. Soc, 

 London, 1893. 



Tamphana is allied to Tarchon, Druce and Apatelodes, Packard, but 

 the wing shape and lateral abdominal tufts distinguish the genus at once, 

 and I shall give full details of the neuration in a paper I am preparing on 

 Walker's American types at Oxford. Arotros belongs to the Bombycidfe ; 

 the neuration only differs from Bombyx, Hubn., in having vein 8 of the 

 secondaries rise from the cell at a third of its length from the base, but 

 the shape of the wings is quite different. In locating the above genera I 

 follow the arrangement of Mr. Hampson, as Messrs. Neumoegen and Dyar 

 place the Bombycidas under the group of families with a frenulum, 

 whereas Bombyx, the typical genus, has no frenulum.

THECLA ONTARIO, EDVV. 



In a small collection of butterflies sent to me for identification, I find 

 a good example of this very rare Hair-Streak, which was taken by Mr. 

 William Metcalfe, of Toronto, at Grimsby, on 24th of June, 1894. This 

 record is important, as it is the first one of an exact date and locality. 

 Mr. Metcalfe states that the exact spot was along the Grand Trunk Rail- 

 way track, near Grimsby Park, at the back of Mr. Harry Griffith's farm. The 

 specimen in question is a male in good condition, although slightly stained 

 with cyanide on the upper side. The figure given by Mr. W. H. Edwards 

 (in his Butt. N. America, I., pi. 2, Tliecla) represents this specimen 

 admirably, although slightly larger. Mr. Metcalfe's specimen expands 

 22 mm., and has the orange spot on secondaries above only faintly 

 indicated by a few rusty scales. J. Fletcher.
