Tills diminutive spc^ries seems to occur CH)mmonly in C'alii'ornia, wiicre 

 it lias been collected by Mr. P^dwards It also occurs at San Mateo, Cal. ; 

 specimens liuving Ix-en collected liy Mr. Alex. Agassiz (Mus. Comp. Zoology). 

 It lias l)eeii taken by Mr. Behrens at Sanzalito, February 4-26, March 22, 

 April 23, May 2. Il may be recognized by i(s small size and wliife, manv- 

 lineated wings. From Guene'e's L. implicata it ditlt'rs in the wings being 

 entirely white, and also in the markings, as well as the smaller size. It may 

 be found to intergrade with E. perUneata of the Eastern States. It is a little 

 larger, and with more acute fore wing.s, than that species or variety (!).

6 c?, 2 9. — Considerably smaller than Ephrifa dilutata, with distinct- 

 ly-pectinated antennae and more triangular fore wings. Palpi small and 

 slender, short, black beyond the middle. Head brown in front; antenn?e dark- 

 brown above, with ciliated, slender pectinations, about twice as long as the 

 antennae are thick. Body and wings light whitish-gray. Fore wings with 

 seven well-marked lines, the three inner and extradiscal lines black, and the 

 most distinct. The basal line very near the insertion of the wing, bent outward 

 acutely on the subcostal and less so again on the median vein. The .second line 

 is brown rather than black below the costa, and situated nearer the third than 

 the basal; it is sharply angulated outward in the costal space, and slightly 

 cnrvi^l below, but not wavy. Thei()urtii line black, forming below the costa 

 a hair-line, and accompanied within by a lirown shade. Both lines disappear 

 between the median and internal vein. A small lilack discal dot, nearly touch- 

 ing a brown, wavy hair-line The extradi.scal line black and heavy in front of 

 the median vein; not bent on the costa as in E. dilutata, but straight, and only 

 curved inward just below the median vein, below which it is wavy. It is
