THE CANADIAN ENTOMOLOGIST. 13 



The three forms, Babayaga, Aspasia and Wahhii, have been more 

 or less confused. While at a casual glance they are very close, still 

 I have no trouble in separating them. The first I have seen from Texas 

 and Arizona. The fore wings have a brownish velvety appearance, the 

 s. t. line not lighter than inside the t. p. line, the t. p. and t. a. lines dark 

 brown with a mesian transverse and s. t. brown shade. The mesian band 

 of the hind wings is very narrow, only slightly expanded in the middle^ 

 abruptly bent at the posterior and not reaching the internal margin. 



Aspasia has the ground colour of a slight bluish tinge, the lines of a 

 deeper brown, almost black, the mesian and s. t. shades more distinct 

 brown, the s. t. line almost or quite concolorous with the ground colour. 

 The mesian band of the hind wings is from a quarter to a third wider than 

 in Babayaga, and often nearly reaches the internal margin by a shade. 



In Walshii the ground colour of the fore wings is much as in Aspasia, 

 but the s. t. line is white or whitish and the shades are less brown, and the 

 m esian band of the hind wings is nearly twice as wide as in Babayaga. 



I have seen Babayaga from Texas and Arizona ; Aspasia from Ari- 

 zona and Colorado ; Wahhii from Arkansas, Missouri and Illinois ; and 

 what may be Junctura from Arkansas. I have not before me Walker's 

 description, and hence do not know the locality he gives for the specimen 

 he described. If I know the genuine Junctura it has more or less white 

 through the middle of the fore wings, as Grote says in one of his descrip- 

 tions, somewhat simulating Unijuga, with the mesian band of the hind 

 wings wider than in either of the first three forms. I have seen such 

 specimens from the East, and one or two from Arkansas in the collection 

 of Mr. T. C. Poling, of Quincy, 111., approximate the eastern forms. On the 

 strength of this I have put Walshii as a variety of Junctura. 



As to the specific status of these forms I have not much to say. I 

 have taken Walshii here in Southern Illinois for more than 20 years, and 

 have never found one intergrading toward what I have called Junctura^ 

 and hence have not shared Mr. Grote's idea that it was a synonym 

 of Junctura, and only place it as a variety for the reason given above. 

 Nor have I seen any intergrading toward Aspasia or Babayaga. It 

 is possible that these four forms are but one species, but it seems to me 

 better to let them stand till by breeding they are proven to be one. 



In another species, Stretchii, I found by breeding that there was 

 considerable variation in the colour of the fore wings, but the mesian band
