 beyond llu' int. r|ial|)al tail, rallicr busliy ; flie second joint broad; third joiuo 

 uiiiinte, eonieal, merged with Iheseeond joint. Fore winirs with the cosia tidl, 

 iircdied toward the a[)e.\, whieli is subrectangular, the winys not l)eiiia- snblal- 

 cate, as in Oclnjrin; outer e(Ig(> not very oblique, .sonu'times sli<rbtlv bent in 

 the n)id(ne. Hind wiiig.s somewhat pnxhiced toward the apex, more so than in 

 Ochyria, sometimes very slightly scalloped. Venation: one (A', /lasta(a) or two 

 subcostal veins, the latter equal, or, with the inner one, small; the posterior 

 discal venule often not bent, somelinu's much as in Ochyna; the .second 

 subcostal venuh' arises half-way between the end of the outer subcostal cell 

 and the origin of the third subcostal. Hind legs thick; tarsi thick, short, 

 not quite so long as the tiluje. Abdomen of moderate leiiirfh. not reachim"'- 

 beyond the inner angle of the winnf, ending in a slight s(piare luft. Colora- 

 tion : there are three styles; in the niJiciUata grou|), there is a i)road whiti; 

 band on the fore wings, and the hind wings arc whiter than usual ; in the 

 second group, represented by lacustraUt, there is u median black l)and, and 

 there are numerous lines on the hind wii:gs; in the third group, represented 

 by R. hasfafa, the body and wings are black, with a white common band, 

 and often large white spots in coimection. 



The species of this genus ditfer trom Odnjrta by the simple; male anten- 

 nae, almost entirely wanting in cilia, and tiu' less snbfdcate wings; while the 

 hind wings arc never angulated, though sometimes scalloped, as in Orlnjrhu 

 Besides these characters, the species are nearly always distinaiushable bv 

 their markings, and tlie general habit of th<> genus is dilferent. The venation 

 is very similar, yet slightly different. Tli(> .species of the group A con- 

 nect the lacmtraUi group 13 with Ochijrui, while haslnta is (piite different. I 

 see no reason why the genus, as here limited, is not as "good"' as those in 

 other subtiinulies of the Pha/cciihla', and do not think that the union of all 

 those genera under the term CUlai-'ta, as insisted on by German writers, will 

 lend to clear conceptions. On the other hand, the geni-ra aiv in a degree 

 artificial. Piobably no two persons will agree u\\ the limits ot'the genera of 

 this subtiunily; at least, in the present state of our knowledge. 



Larva. — "Caterpillars quite" short, cylindrical, slightly attenuated in 

 front, with trapezoidal points, surmounted with small, quite visible hairs; 

 without lines, or with a few lines; head globular; living on tree.s or low 

 plants. Pupa- contained in oval eaiiheii cocoons." — (uu'iiee.
