ending in a slight knob with a few bristles; in dorsimacida the end of 

 the clasper is decidedly spoon-shaped and terminated by a distinct spine 

 approaching in this respect faiistinula Bdv., the clasper of which seems 

 to have an identical shape; nexa Bdv., which Williams claims (1905, 

 Ent. News, XVI, 257) to be merely a form of faiistinula has a decid- 

 edly different form of clasper, more allied to that of liberomacula 

 but with the narrow distal end shorter and the base broader. Stretch's 

 figures (Zyg. Bomb. N. Am., PI. 2, Figs. 10, 11) should serve to 

 readily distinguish nexa and faiistinula and we can only conjecture that 

 Williams either collected unknowingly the larvae of both species which 

 possibly show no particularly distinctive features or else that his identi- 

 fications of Boisduval's species were incorrectly made. 



A form of liberomacula which is seemingly commoner than the 

 type form and which is distinguished by the presence of a white streak 

 above the inner margin from the base to the postmedian white spot, 

 is without a name; we propose for this form the name basijuncta 

 (PI. XIV, Fig. 9), our type series being numerous specimens from San 

 Diego, Calif.

EUBAPHE LAETA Guer. 



The figure given of this species (Icon. Reg. Anim. Ins. PI. 88, 

 Fig. 6) would seem to point to the typical form as being the southern 

 one, common in Florida, characterized by small size and considerable 

 brown shades in the color of the primaries; the northern race we had 

 separated in our List under the name rubropicta Pack, based on a 

 specimen from Rangeley, Me.; we have, however, recently seen the 

 type of treati Grt. in the Cambridge Museum Coll. and believe that 

 this name will take priority over Packard's, based as it is on a Massa- 

 chusetts specimen. We could not find the type of rubropicta at Cam- 

 bridge but judging by material before us from Maine the two names 

 are synonymous. The northern race is larger and the primaries show 

 much more of a gray tint than we find in the typical form; the race 

 extends westward to northern Illinois and Manitoba. 



EuBAPHE FRAGILIS Stkr. (PI. XIV, Fig. 13). 



An examination of the type of this species in the Field Museum, 

 Chicago, shows that it agrees stnicturally (length of palpi) with im- 

 maculata Reak. and probably is merely the Colorado race of this
