I can see no reason for separating any of these synonimic forms. 

 Dr. Ilerrich-Schaeffer has, indeed, united Atii/fa and Daeta, and very 

 curiously given the former name the preference. There is no percep- 

 tible difference either in color or venation between my specimens of 

 Daeta (type) and of Etiryanassa^ both of which I have very carefully 

 determined by comparison with figures and diagnosis. Laphria is the 

 only form which could, by undue straining, be considered even a vari- 

 ety, and the departure is so very trifling that it hardly merits this slight 

 distinction. 



4. Mechanitis Californica. n. sp. 



Expanse 2.45 — 2.56 inches. Fore wing above, brownish-black, a 

 basal streak over the median nervure, and two rounded spots near the 

 inner angle, orange-tawny; of these the outer is the largest, sometimes 

 the inner is yellow, and sometimes both are nearly obsolete — a spot 

 across the cell near its termination much narrower than in M. Isthmia^ 

 and in one example, (B) reduced to a mere dot on the median nervure, 

 a more or less interrupted belt across the wing from the costa to near 

 the middle of the outer margin, and an oblong subapical spot, yellow ; 

 in specimen B, just mentioned, there is an additional yellow spot below 

 the medio-central veinlet. 



Beneath the same, suffused with orange-tawny at the base, and the 

 inner angle, with a row of eight or nine submarginal white spots along 

 the outer margin. 



Hind wing above, orange tawny, with a broad mesial band, entire, 

 and a narrow outer border, fi-om the middle of the costa to the anal 

 angle, brownish-black. 



Benuath the same, a yellow spot on the root of the wing; a band runs 

 alonjj the subcostal nervure from the base to the marfj;in, where it is 

 somewhat dilated; immediately below its termination, a mark in the 

 form of an irregular figure 2, usually with the upper part inordinately 

 enlarged ; between this and the base, on the central line of the band 

 above, three small subtriangular spots; all these markings blackish- 

 brown ; a submarginal row of seven white spots on the outer margin. 



Body brownish; wing lappets and thorax spotted with tawny-orange; 

 antennai yellowish, with the base dusky.

This beautiful species is closely allied to Mechanitls Isthmia Bates, 

 both being local segregations of the protean M. Polt/mnia^ to which, 

 however, Californica species is more nearly allied.
