THE CANADIAN ENTOMOLOGIST. 53 



Alope in this State. Pegala flies in some portions, but rarely. I do not 

 think Alope is found here." The late Dr. O. C. Sparrow resided some 

 time at Valdasta, Lowndes Co., Southern Georgia, and sent me 

 thence several examples of Pegala. He wrote 13th July, 

 1877: " I have never taken Alope here." On 7th Aug. he says: "I 

 have seen a good many Pegala. In a stroll to-day I took 3 males." Dr. 

 Chapman says : " I have never seen Alope anywhere in the south. Our 

 grasses here are all hard and coarse, and we have no cultivated ones like 

 the Blue grass, Red-top, English grass, &c. The kinds of grass which 

 grow here in the pine woods are found in nearly all the States which have 

 what we call the 'pine-barrens.' " 



Messrs. Boll and Belfrage, professional collectors, long resident in 

 Texas, can give me no information about Pegala. Mr. Belfrage writes : 

 " It is not found in Bosque Co., and so far as I can remember, I have not 

 seen it in Texas. Alope is common in my locality." Mr. Heiligbrodt, at 

 Bastrop, Texas, says that Alope at times has been common, but he does 

 not know Pegala. Mr. Otto Meske tells me, however, that in 1876 he 

 received a Pegala male from Bastrop, the only one he ever saw from Texas. 



Not only therefore do I find no evidence that Pegala and Alope fly (i. e. 

 habitually) in the same districts, but there are no intergrades forthcoming. 

 There are no doubtful examples as in the case of Alope and Nephele in the 

 belt of dimorphism before spoken of. If they were varieties of one species 

 as some have asserted, or forms of one species, there would be a belt of ter- 

 ritory inhabited by the typical forms and all manner of intergrades. On 

 the contrary, there is a belt which separates these forms and is in effect 

 inhabited by neither. The distinction between the two is as clear as 

 between some unquestioned species in almost every genus of butterflies. 

 They are separated by their markings, their habits, and by the food of 

 their larvae. Also, according to Abbot, if the figures in Bois. and Lee. 

 were drawn from Pegala, as supposed, by differences in larvse and very 

 important differences in chrysalids. 



There are in my own collection and in those of friends to whom I have 

 written, 29 examples of Pegala, 21^,8°.. Of these males, 14 have one 

 ocellus on fore wing, 6 have one ocellus and a black dot, 2 have one 

 ocellus and a small black spot. Of the 8 ^, 5 have one ocellus, 1 has 

 one and a small spot, 2 have two complete pupilled ocelli. 



Of 21 g , 17 have 6 ocelli beneath the hind wing, 3 have 5, and 1 has 

 5 on one wing and 6 on the other.
