typical to. We wish to call attention to the fact, however, that there are 

 several names in the synonomy of to, but until the true status of these names 

 is carefully worked out, we are labeling our Northern forms, A. to race fuscus. 

 Should A. fuscus, Wlk. prove to be a true Automeris then the Northern 

 race of to will have to go under the name of lutheri, Ckll ; unless by that time 

 one of the earlier names is found to be the same. Prof. Cockerell's name 

 lutheri is simply intended to take the place of fuscus, Luther because of 

 fuscus, Wlk. Type locality, Rhode Island.

The single female before us has the strong purplish suffusion to 

 the secondaries mentioned by Prof. Cockerell in his original descrip- 

 tion. Three males differ considerably, one having nearly the color and 

 maculation of fuscus but the reniform is only about one third normal 

 size. In this specimen the ocelli of the secondaries make contact with 

 the black lines. The two other males have the reniform larger, nearly 

 normal and while the ocelli of the secondaries do not touch the black 

 lines they are much closer to it than in typical io or fuscus. We strong- 

 ly doubt, however, that this character will prove of much value. 

 These two males have a tendency toward the reddish suffusion found 

 in lilith, especially pronounced in one of them. Our specimens are all 

 from Golden, Colo. (Oslar). Type locality, Boulder, Colo.

This is perhaps the most distinct race of A. io; possibly worthy 

 of subspecific rank. Messrs. Packard and Cockerell (1914, Mon. 

 Bomb. Moths N. A.), have shown that the larvae presented differences 

 from the larvae of A. io. Mr. Strecker described from females, but 

 the name must stand as a "blanket name" for two different forms of 

 males. 



Some males have the primaries a deep yellow color, nearly as 

 in "typical" io while others have the primaries suffused with brownish- 

 rufous. Of course, either of these males could be assigned to the 

 name and the other given a form name. This we dislike to do, how- 

 ever, for two reasons. One is that all intergrades are present in the
