The larval stages have been fully worked out from alcoholic

Differs from all other members of the genus in that the outer mar- 

 gin of primaries is convex below the apex. We know of no other 

 beyond the type specimen in Dr. Barnes' collection. 



Habitat : — Texas, Kcrrville.

There seems very little doubt but that medusa is a slightly aber- 

 rant 9 form of gargamelle. Judging by the original description 

 Strecker had both sexes before him at the time of describing garga- 

 melle. The Strecker Collection in the Field Museimi, Chicago, pos- 

 sesses, however, only a single S type and no record of a 9 . The 9 

 described by Strecker evidently belonged to a rather uncommon bright 

 brown form, of which Dr. Barnes possesses several specimens. The 

 ordinary color of the 9 is a deep black-brown, as in medusa ; this lat- 

 ter, however, is an extreme form with the ordinary markings obsolete ; 

 we have a specimen from California agreeing with the type, and a long 

 series from Arizona of bred specimens shows all intermediate grades 

 both of color and markings between it and gargamelle. The species 

 without doubt is a very variable one, both in regard to color and macu- 

 lation ; in a series of 20 S S before us about one-half are distinctly 

 reddish-brown ; the others vary from light to dark gray-brown ; in 

 some cases the banding is quite distinct, in others it is almost obsolete, 

 especially the subterminal irregular line. The dark gray-brown form
