N. Y., and three others in the Brooklyn Institute as Eustroma nuhi- 

 lata, and these show that Hulst's generic reference is correct, but it 

 is a very distinct species and has nothing to do with immanata. 

 The name atrifasciata is omitted from the index in Dyar's Catalogue 

 and this coupled with the fact that it does not appear as a Cleora 

 led Dr. Holland to conclude that the reference was overlooked 

 (Moth Book, p. 344). 



91esoleuca etiiela Hulst (Trans. Am. Ent. Soc, xxiii, 283, 1896). 



It has been suggested that this species is a form of 3f. hersUiata 

 Gn. Of the many forms of this latter species that I have seen 

 none approached in coloration the peculiar combination displayed 

 in ethela. Besides the type there is another identical specimen, also 

 from Sierra Nevada, California, in the Edward's collection in the 

 American Museum. The perfectly immaculate, pale yellow sub- 

 basal area is singular, and there are other points which if they 

 prove constant in ethela will hold the species abundantly distinct 

 from hersUiata. 

 Wesoleuca abacta Hulst (Can. Ent., xxx, 117, 1898). 



I believe that this will eventually fall before Hijdriomena reflafa 

 Grt. I have only the type of the former before me and a speci- 

 men of the latter, which I have identified from the description, and 

 while they represent respectively a light and dark form the delinea- 

 tions and structural characteristics are precisely alike. The species 

 is best referable to Hydriomena. 



Hydriomena occidens Hulst. 



The receipt of additional specimens of this species has convinced 

 me that Dr. Dyar is right in referring it as a synonym of curvilinea 

 Hulst. 

 Hydriomena grandiosa Hulst (Can. Ent., xxx, 118, 1898). 



The male type at New Brunswick is the same as Mesolexica impli- 

 cata Gn., and Dr. Dyar tells me that the female type in the National 

 Museum though larger and looking rather different from implicata 

 is nevertheless probably that species. I think it is quite safe to say 

 that both names apply to the same thing. The species is almost 

 intermediate in structure between Hydriomena and Mesoleuca, but 

 is probably best referable to Hydriomena.
