Some Results of Breeding Moths of the Genus 

 Haploa Hiibner. 



B\- Frank H. Foster, Claremont, N. H. 



The task of systematists in classifying the moths associated 

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

 the wide variability among the imagos of neariy all the recog- 

 nized 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. Lyman's article and plate in October. 1887, 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 b}' 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 onh* compliment Mr. Lyman's tact in sorting the moths. 

 I had the opportunity of examing a lot of clyitiene 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 Datana and Hemilcuca , Callimdrpha (synonymous 

 with Haploa) 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 Progeneric.'"' 



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

 duce the number of forms entitled to specific rank. Thus 

 L^nian in 1887 (Can. Ent., Vol. XIX. pp. 190-191) gives 

 eight species and two varieties. 



Smith in same 5'ear (Can. Ent., Vol. XIX, pp. 238-239) 

 gives nine species and one variety Xeumoegen and Dyar in 

 1893 (Journal of Xew York Entom. Society, September, 1893, 

 pp. 158-161) give eight species and four varieties. 



Dr. Dj-ar's present classification, as stated in a recent letter 



* Can. Ent., Feb., 1888, Vol. xx, pp. 39-40.
