HARRISON G. DYAR. 19 



Geuus DATANA Walker. 

 1855.— Walker. Cat. Brit. Mus. v, 1060. 

 1894. — Neumoegeu and Dyar, Trans. Am. Ent. Soc. xxi, 197. 



Type D. ministra Drury, The other species are angusii G. and 

 R., californica Riley, drexelii Hy. Edw., major G. and R., palmii 

 Beut., jioridann Graef., modeda Beut., persjncuu G. and R., robusta 

 Streck., mtegerrima G. and R., chiriquensi^ Dyar and contrada Walk. 



The larvae have the warts reduced, scarcely distinguishable from 

 the secondary hair. They are black, longitudinally banded with 

 yellow or white, the bands usually continuous. 



Genus l» HAIDER A Hiibner. 

 ISIS.— Phahra Hiibner, Verz. bek. Schmett. 146. 

 1832. — Acrosema Meigen, Eur. Schmett. iii, 24. 

 1851.— Hammatophorn Westwood, Brit. Moths i, 63. 

 1892.— Plmlera Kirby, Cat. Lep. Het. i, 575. 

 1892.—Phalera Hampson, Moths of India i, 133. 



Type P. bucephala Linn. The other species are bucephaloides 

 Ochs., parivala Moore, sangana Moore, torpida Walk., procera Fel- 

 der and raya Moore. 



The larva of the type is similar to Dcdana, the lines broken by 

 transver.se shades. Other species are considerably nsodified from this 

 pattern of coloration, e. g. bncephaloides and raya. 



My example of parivala differs from the type in having the ac- 

 cessory cell stalked nearly as far as the origin of vein 6. The cross- 

 bar at the end of the accessory cell is faint in one wing and absent 

 in the other, so that the accessory cell is really absent. Hampson's 

 figure of jjarivala is, however, normal, and I can only regard my 

 example as an aberration.
