Some Results of Breeding Moths of the Genus 



Haploa Hubner. 



By FRANK H. FOSTKK, Claremout, N. H. 



The task of systematists in classifying the moths associated 

 tinder this genus has been an unusually difficult one, owing to 

 the \vide variability among the images of nearly all the recog- 

 ni/ed species and the absence, so far as known, of any constant 

 structural differences. 



Mr. A. R. Grote's remarks upon this genus* called forth by 

 Mr. Lynian's article and plate in October, i.SSj, number of 

 Canadian Entomologist seem so eminently pertinent that I 

 quote them here in part. 



"It will be no question with the derivatists that these forms 

 are all descended from a single species. The test by breeding 

 from the egg must now decide whether these forms have each 

 an independent cycle of its own or are interdependent still. 



'The test for species remains to be applied to them. As yet 

 we can only compliment Mr. Lyman's tact in sorting the moths. 

 I had the opportunity of examing a lot of clynicnc taken in the 

 vicinity of Buffalo, and I came to the conclusion that it was 

 possible that the yellow and white forms are yet interchangable. 

 Like Data>ia and IJcmilciica, Calliniorpha ( synonymous 

 with Ifap/oa ) is an example of a generic group in which the 

 species or forms are more nearly related than usual and is thus 

 one of those assemblages which I have called /'tvgrucric." 



The tendency has been for later and fuller knowledge to re- 

 duce the number of forms entitled to specific rank. Thus 

 Lyman in iSSj (Can. Ent., Vol. XIX. pp. 190-191) gives 

 eight species and two varieties. 



Smith in same year (Can. Ent., Vol. XIX, pp. 2^-239 ) 

 gives nine species and one variety Xeiimoegen and Dyar in 

 X 895 (Journal of Xew York Entoni. Society, September. 1^03, 

 pp. i^S-iGi I give eight species and four varieties 



Dr. Dyar's present classification, as stated in a recent letter 



Can. Pint., Feb., 1888. Vol. xx, pp. 39-40.
