The primaries are siiort, subequal, with rectangular apices, outer 

 margin straight to middle, then obliciuely inward, angle not retracted. 



The genitalia of the % , so far as known, are referable to three 

 types, or rather there are two types, and two of the species which 

 are otherwise very close to others are aberrant in this respect. 



The species are readily divisible into two series — the first with 

 broader primaries, bright colors — yellow forming a prominent feat- 

 ure, distinct, oblique or slightly sinuate median shade line, and well 

 defined ordinary spots; the second with distinctly narrower prima- 

 ries, dull colors of which luteous usually forms a base, median shade 

 line usually distinct, but angulated above middle. Ordinary spots 

 not defined, orbicular in all except ;^-stig])iata obsolete. The first 

 series QO\\i7\\\\s gricfiana, ))ioffatiana, pcttiti 'aw^X ceromatica. Except 

 uwffatiana, these species have practically similar genitalia. The 

 harpes are broad, the upper margin thicker, chitinous, curved and 

 produced into a blunt, rounded tip, from the lower edge of which 

 projects a small acute spur. The clasper is a rather long, stout, 

 corneous hook, extending nearly to the end of the projecting harpe, 

 and but moderately curved. The slight differences in detail between 

 the species are better noted by a comparison of figures than by any 

 description. 



I head the species with grcefiana, which is pale ocher-yellow, 

 with rigid, single, median lines and an almost equally rigid median 

 shade line. 



Moffatiana is closely allied in color and maculation; so closely 

 indeed, that for a long time they were considered identical. The 

 superficial differences narrow to a deeper, more reddish ground 

 color, and less rigid transverse lines. The t. a. line especially, is in 

 this species usually bent on the subcostal vein. The $ genitalia 

 are of an entirely different type from the other species of the group. 

 The harpes are narrow, elongate, the upper margin straight, the 

 inferior margin obliquely curved, meeting the upper margin in an 

 acute point at tip. From the middle of upper margin e.xtends a 

 corneous rib, obliquely downward and projecting as a spur consid- 

 erably beyond the margin of harpe. The clasper arises rather near 

 the base of the harpe, is stout, strong, obtuse and somewhat enlarged 

 at tip and forms an irregular half circle. This strong difference in 

 species otherwise so nearly allied is remarkable. 



Pettiti is a small species, the smallest of the genus in fact, the 

 ground color like moffatiana, but all the maculation indistinct. From 

 both the preceding it difilers by the crenulate t. p. line. 



Ceromatica agrees with pcititi in the crenulate t. p. line, but it
