Enarmonia argutana Walsingham, Biol. Cent. Amer. Lepid. Heter., vol. 4, 

 1914, p. 238. 



A rather common species and probably the most widely dis- 

 tributed of all, occurring throughout North and Central America 

 and the West Indies. Dyar has suggested the synonymy of hama- 

 meliella and argutana and in this is without doubt correct. Several 

 of the moths in the National Collection Avere reared from Hama- 

 melis. The favorite food plant, however, seems to be sumac {Rhus 

 glabra and E. copalina, less frequently B. toxicodendron) . There is 

 some little color variation in different specimens due to the amount 

 of dark dusting upon fore wing; but the pattern markings other- 

 wise are uniform. 



Male genitalia figured from specimen in collection Barnes from 

 Shasta Retreat, Siskiyou County, Calif. ("June 16-23"); female 

 from reared specimen in National Collection from Glencarlyn, Va. 

 (on Rhus copalina, Hopk. U. S. no. 12133, June 10, 1914, Heinrich).

 (Fig. 393) 



Grapholitha {Hedya) augmentana Zeller, Hor. Soc. Ent. Ross., vol. 13,

Epismius augmentanus Dyar, Proc. Ent. Soc. Washington, vol. 4, 1901, p. 

 468. — Fernald, in Dyar List N. Amer. Lepid., no. 5206, 1903. — Barnes 

 and McDuNNOUOH, Check List Lepid. Bor. Amer., no. 7109, 1917. 



Represented in the National Collection by two reared males from 

 Palm Beach, Fla. (Dyar, no. 843, iss. Feb. 25 and 27, 1900). These 

 are the only North American specimens I have seen. Male genitalia 

 figured from one of the above. 



The species is very similar in pattern to the tropical transferranus 

 Walker, but is apparently distinct.
