Kcntuckiensis Dyar we do not know ; it was described (1904, Proc. 

 Ent. See. Wash., VI, 198) as a broad-banded form of unifascia and as 

 such we leave it. 



Perrosea Dyar, (1. c. p. 198) (PI. XIV, Fig. 7) also described as 

 a variety of unifascia, is a good species; the clasper is broad at the 

 base, narrowing suddenly into a long slender prong bent inwards 

 towards the apex and touching that of the opposite side ; angclus Dyar, 

 (PI. XIV, Fig. 8) described as a good species, (1. c. p. 198) has a 

 very similar type of clasper and may prove to be a racial form, al- 

 though easily separable on maculation with its entirely ochreous thorax 

 and broad band on basal two-thirds of inner margin. 



Barnesi Dyar (PI. XIV, Fig. 10) is a good species and not a form 

 of unifascia; the clasper has a broad basal portion similar to that of 

 perrosea but instead of being produced into a long slender point it 

 shows a long prong arising from its dorsal margin and bent sharply 

 downward with a short tooth on the inner margin of the prong near 

 the base ; the species occurs in two color forms ; the typical form has 

 pink secondaries ; for a rather rarer form with yellow secondaries we 

 propose the name flavula, our types being 3 $ and 1 9 from 

 Glenwood Spgs., Colo. 



We have 4 specimens before us from Texas (no further locality 

 on label) which superficially in size and maculation bear a close resem- 

 blance to angelus but which show a type of clasper very similar to 

 barnesi; the thorax is entirely yellow, the primaries have a broad 

 yellow band along inner margin and a transverse yellow postmedian 

 band considerably narrowed in central portion; the secondaries are 

 pink with a smoky patch at apex descending to about the center of 

 the outer margin ; there is a slight trace of sexual hairs along the anal 

 margin in the $ but scarcely sufficient to warrant placing the species 

 in Osodania; we propose the name picta (PI. XIV, Fig. 11) for this 

 species, which is probably confused in collections with unifascia, 

 although considerably larger in size ; our types are 1 <J , 3 9 received 

 at various times from older collections which accounts for the lack of 

 data on the label. 



According to the form of the claspers we believe liberomacula 

 Dyar (PI. XIV, Fig. 6) must be considered a good species and not a 

 form of dorsimaciila (PI. XIV, Fig. 12) as placed in our List; in 

 liberomacula the distal end of the clasper is evenly long and narrow.
