but for all that, the typical Zygcenids of South and Central Amer- 

 ica (the home of the family,) generally possess more distinctly 

 Liparidiform larvae than do the Arctiidce, giving one the impres- 

 sion that a boundary line must exist somewhere. Although for 

 convenience of reference I retain GnopJicela in the Zygcenidcs I am. 

 quite prepared to hear that it is a true Arctiid. 



Gnoph^la vermiculata. Grote and Robinson. 



A male from Colorado. 



This species appears to come nearest to G. equinoctialis, a 

 female of which from Mexico I found associated with Pericopis in 

 our collection. It also somewhat resembles the male of P. 

 aglatira, Cramer, but the secondaries in GnopJicela are a little nar- 

 rower than in Pe7-icopis. 



Dahana atripennis. Grote. 



A specimen from Florida. The genus appears to me tO' 

 come nearest to Syntovicida, but the body is less robust.

I have long wondered what difference could exist between 

 C. rubroscapus and C. walsingJiaviii, but until now have never 

 compared them, as all the examples hitherto standing in our col- . 

 lection under both names are referable to the nearly allied C. 

 vmltifaria of Walker. 



It will be seen by a reference both to the description and figure 

 by Menetries that there is no hint of a white costal margin in C. 

 rubroscapus, and as this is the only distinguishing character be- 

 tween C. multifaria and C. ivalsinghamii the name must neces- 

 sarily go. The only question in my mind is whether this costal 

 character can be relied on, but of this my friend, Mr. Edwards,, 

 will be a better judge than I. 



ARCTIID^ (typical). 



Leptarctia LENA, Boisd. = californiae. Walk.* 



Knight Valley and Havilah, California. 



I cannot distinguish the examples sent by Mr. Edwards from
