Paratypes. — In National Collection, American Museum, and collec- 

 tion Barnes, 



Type locality. — Caldwell, New Jersey. 



Food plant. — Prunus. 



Described from male type from Caldwell, New Jersey (" May 17-03, 

 W. D. Kearfott"), 3 male paratypes from Oak Station, Penn- 

 sylvania ("May 22-08," and " V-22-10," "Fred Marloff"), 2 male 

 paratype from St. Louis, Missouri ("¥-14^05, McElhose"), 1 male 

 paratype labeled, " from cultivated cherry, 5-22-85 " and 1 male 

 paratype labeled "273 M, on wild cherry, ^29-85." The last two 

 specimens have been for many years in the National Collection un- 

 der the name hurgessiana Zeller. 



In view of the confusion and uncertainty that prevails in regard tc 

 several species in this genus (namely, laciniana., spiraeifoliana^ duh- 

 iana, and pulchelluna) I dislike to add a further name to the list. 



It is advisable, however, to have names to distinguish the oak and 

 Prurnis feeding forms. I think they are one species; but there is 

 always the possibility that they are not, and since they are at least 

 distinguishable as food plant races on the color of the hindwings it 

 seems but the wisdom of caution to so separate them. A too fine 

 splitting can always be corrected, but a false lumping is not as easily 

 remedied and is fruitful of nothing but confusion. 



11. ANCHYLOPERA LACINIANA (Zeller). 



(Fig. 397.) 



Phoxopteris laciniana Zeller, Verh. Zool.-bot. Ges. Wien, vol. 25, 1875, p. 253. 

 Ancylis laciniana Feenald, in Dyar List N. Amer. Lepid., no. 5247, 1903. —

List Lepid. Bor. Amer., no. 7190, 1917. 



This species has also been badly juggled. Zeller's description is 

 plain enough and can hardly refer to anything else than the form 

 here determined. There is, however, in the Fernald collection a 

 specimen from Massachusetts, labeled in Zeller's handwriting and 

 possibly one of his cotypes, which agrees better with what I am call- 

 ing spiraeifoliana than with any of our conceptions of laciniana; but 

 then it does not agree with Zeller's description either and as there 

 is little likelihood of its being the actual type we need not appeal 

 to it against the description. 



Male genitalia figured from specimen in National Collection from 

 Mountain Lake, Virginia ("14-21, June, 1907, A. F. Braun").
