ciliated. Palpi shod and stout, slightly raised, extending but a short distanct 

 beyond the interpalpal tuft, rather bushy; the second joint broad ; third joine 

 minute, conical, merged with (he second joint. Fore wings with the costa full, 

 arched toward the apex, which is subrectangular, the wings not being subfal- 

 cate. as in Ochyria; outer edge not very oblique, sometimes slightly bent in 

 the middle. Hind wings somewhat produced toward the apex, more so than in 

 Ochyria, sometimes very slightly scalloped. Venation: one (R. hastata) Or two 

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

 discal venule often not bent, sometimes, much as in Ochyria; the second 

 subcostal venule 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 tibiae. Abdomen of moderate length, not reaching 

 beyond the inner angle of the wing, ending in a slight square tuft. Colora- 

 tion : there are three styles; in the ruficillata group, there is a broad white 

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

 second group, represented by lacustrata, there is a median black band, and 

 there are numerous lines on the hind wings; in the third group, represented 

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

 and often large white spots in connection. 



The species of this genus differ from Ochyria by the simple male anten- 

 na', almost entirely wanting in cilia, and the less subfalcate wings; while the 

 hind wings are never angulated, though sometimes scalloped, as in Ochyria. 

 Besides these characters, the species are nearly always distinguishable by 

 their markings, and the general habit of the genus is different. The venation 

 is very similar, yet slightly different. The species of the group A con- 

 nect the lacustrata group B with Ochyria, while hastata is quite different. I 

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

 other subfamilies of the Phalcenidce, and do not think that the union of all 

 those genera under the term Cidaria, as insisted on by German writers, will 

 tend to clear conceptions. On the other hand, the genera are in a degree 

 artificial. Probably no two persons will agree on the limits of the genera of 

 this subfamily; 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 trees or low 

 plants. Pupae contained in oval earthen cocoons." — GueueV
