338 AMERICAN LEPIDOPTERA. 



mata is said by Dr. Dyar to be the same as Coryphista badiaria Hy. 

 Edw. and generically distinct from Philereme. In the systematic 

 arrangement multivagata and nigrescens may follow Mesoleuca aurata 

 Pack. (^ ccesiata of American authors), while formosa may fall in 

 after hersiliata to which it is a close ally. 



Mesoleuca aurala Pack. (Proc. Bost. Soc. Nat. Hist., xi, 51, 1866). 



This name will have to be used for the American insect that at 

 present goes under the name ccesiata Den. and Schiff. I have seen 

 a large series of European specimens in the Packard collection and 

 there are probably forty examples of the American species in the 

 Museum of Natural History in New York. The position of the 

 transverse lines is approximately the same in each, but in ccicsiata 

 they are dark brown, very clearly defined, and in strong contrast to 

 the almost white ground color, whereas in aurata the ground color 

 is gray, the lines are indefinite and can scarcely be followed across 

 the wing in some cases, and these differences obtain throughout the 

 series of each species. The illustration in Packard's Monograph, 

 plate 8, fig. 16, represents the European species, though his descrip- 

 tion (1. c, p. 67) is that oi aurata. Mr. Butler in Papilio, vol. i, p. 

 222, says after seeing a Californian specimen that it is not the 

 ccesiata of Europe, the occurrence of which he doubts in America. 

 Whether this note of Mr. Butler's was overlooked by later writers 

 or whether they did not coincide with his opinion I am not in posi- 

 tion to say ; but at any rate he was never followed and ccesiata is 

 still found on our latest lists. 



A reference to aurata seems to have been overlooked by Packard 

 in his Monograph, and not having the particular paper in which 

 the description appears, the reference above was kindly furnished 

 me by Dr. Dyar. 



JVIesoleuca atrifasciata Hulst (Ent. Am. iii, 214, 18S8). 



This species, originally described as a Cleora, was later referred as 

 a synonym of Mesoleuca truncata var. thingvallata (Ent. News, vi, 

 43), which variety now appears in Staudinger's latest list as an 

 aberration of immanata. In Dyar's Catalogue it is cited as a syno- 

 nym of immanata, not even varietal rank being accorded it. In the 

 Hulst collection a female specimen of atrifasciata stands as a Eust- 

 roma, where it would seem to belong as far as habits is concerned. 

 I have recently seen an unnamed male in the American Museum,
