SYNONYMIC NOTES ON NORTH AMERICAN 

 HETEROCERA 



SATURNIIDAE 



COLORADIA PANDORA Blake. 



Dr. Dyar after sinking lois Dyar to doris Barnes proposed the 

 name loiperda (Proc. Wash. Ent. Soc. XIV, 155) for what he con- 

 sidered a form of pandora without pink shading on the secondaries. 

 We have compared material with the types of both pandora at Phila- 

 delphia and loiperda in the National Museum and find them practically 

 identical, the $ type of pandora showing scarcely a trace of pink. 

 Personally we do not believe that this pink shading on the secondar- 

 ies has any specific value whatever; in series before us from a single 

 locality individuals are found with heavy pink shading and others 

 with not a trace of the same, but otherwise identical. In any case 

 whatever stress may or may not be laid upon this feature, loiperda 

 will sink to pandora as both represent the same form. 



ARCTIIDAE 

 LITHOSIINAE 



Illice unifascia G. & R. 



We have been unable to locate the types of this species which 

 was described from specimens from Florida and Texas. Fortunately 

 the figure given by Grote is distinctly good (Tr. Am. Ent. Soc. II, PL 

 II, Fig. 63) and the species can be definitely identified as that one 

 with a rather broad yellow band crossing primaries, this band being 

 somewhat dilated at costal and inner margins and joined to the base 

 of wing along inner margin by an evenly broad yellow band ; the $ 's 

 are practically similar to the 2 's (the figure being that of a 2 ) and 

 are typical members of the genus Hike, the inner margin of the sec- 

 ondaries not possessing a projecting tuft of hairs at the anal angle. 

 We mention this fact because tenuifascia Harv., which has commonly 

 been called a variety of unifascia, appears, if our identification be 

 correct, to possess such a tuft in the $ sex and falls properly into the 

 genus Ozodania Dyar. The type of tenuifascia appears to be lost; 

 the species was described from Bosque Co., Texas, and briefly char- 

 acterized as being a little larger than unifascia with a narrower yellow
