Catalogue of the Phal^nid^e of California. 

 By A. S. Packard, Jr., M.D. 



' The following notes are taken from a monograph of the North 

 American species of this lepidopterous family in course of prepara- 

 tion. The new species here described were kindly communicated 

 by Messrs. Henry Edwards and J. Behrens of San Francisco, Cal. 

 A few species, and those among the most interesting, are from Ne- 

 vada. 



The occurrence of the genus Heterolocha, not before found in 

 North America ; of a species of Rumia more closely allied to the Eu- 

 ropean R. cratcegata than R. sulplmrea Pack. MS. found in Maine, 

 and of a species of Chesias, indicate that in this family as in the 

 Bombycidae, the Nocturnal Lepidoptera repeat on the Pacific slope of 

 our continent certain features peculiar to the European, or western 

 shores of the eastern hemisphere, as has been observed in the Diurnal 

 Lepidoptera, the Neuroptera, and the Crustacea and Mollusca of 

 California. 



Unless otherwise stated the specimens were collected in California. 



The types of the new species are contained in the Museum of the 

 Peabody Academy of Science, Salem. 



Choerodes nubilata n. sp. 9 . 



Closely allied inform and structure to C. transversata\ the fore wings 

 slightly more falcate, but the hind wings a little less caudate. Fawn 

 colored, like dark individuals of C. transversata. Head, palpi and 

 body concolorous with the base and outer edge of the wing, being 

 specked with black scales and short strigse. On the basal third of 

 wing, is a very distinct dark, zigzag, broad, diffuse, blackish band, not 

 reaching the costa, being most distinct on the hind edge; the outer 

 line is brown, and is curved on the submedian cell, thence going 

 straight to near the apex where it is reflected at an acute angle on to 

 the costa; the angle, however, is less acute than in C. transversata, and 

 the reflected portion half as long. Just outside of this line are five 

 diffuse blackish patches, one on the inner edge near the angle, the 

 other resting on the apex, and forming a diffuse oblique line which 

 passes within the angle of the outer line. The median part of the 

 wing between the two lines is clear tawny fawn color, with obscure 

 large transverse strigse not present elsewhere on the wing. The dis- 

 cal dot is large and distinct, smaller on hind wings. Hind wings with 

 thick diffuse strigse, less fine than on fore wings, and a single outer
