THE NOCTUID MOTHS OF THE GENERA PALINDIA AND 

 DYO]\IYX.

These strikingly colored Noctuids have long been favorites with 

 collectors. They are best known under the name Palindia of Guenee. 

 The DyowAjx have been generally associated with the Palindia, and 

 are apparently allied. Dyomyx has a very long thhd joint to the 

 palpi and presents none of the modifications of the hmd tibise of the 

 male, so general in Palindia. Some of the species have been fre- 

 quently interchanged between the genera. 



The first species of Palindia made known were by Cramer, under 

 the general terms Phals&na Noctua and Phalsena Geometra. Hiibner 

 ranged them m two genera, Eulepidotis and Phrygionis. The type 

 of the latter is generally considered to be cuUaria Hiibner ( = politata 

 StoU, not poUtia Cramer), the first species, a Geometrid. Of the 

 former, the type is ilyrias Cramer, the first species, fixed by Butler 

 (1892), a Palindia. Guenee next established Palindia and Dyojnyx. 

 Walker made no new genera in this group. Butler divided Palindia 

 in three pai'ts, using Eulepidotis for the green ones, Palindia for 

 the white ones, and Phrygionis for the yellow ones. Bar placed 

 them all in Palindia, included Dyomyx as closely related, if not a sub- 

 genus, but separated the species with curved outer line under the 

 name Calydia. The species will be treated here as done by Guenee 

 under two names, but it will be necessary to substitute the older 

 Eulepidotis for Palindia. 



Three species have been reported in the United States, Eulepidotis 

 dominicata Guenee from southern Texas, where it may even be estab- 

 lished, E. micca Druce, recently reported from Texas by Barnes and 

 McDunnough, and Dyomyx merricki Holland from Pennsylvania, 

 where it was probably accidentally imported on tropical fruit. 



Nothing is known of the larvae or life history of any of the rather 

 numerous species. One hundred and three species are here considered 

 of Eulepidotis and twenty of Dyomyx.
