LEUCANIA FARCTA, Grote. 



Heliophila farcla (jROTK, Van. Ent., XIJl, 1881, p. 15. 

 Leucania farcta Smith, Bull. 44, U. S. Nat. Mus., 1893, p. 188. 



Ground color a pale creamy yellow. Collar with three somewhat 

 purplish transverse lines. Primaries strigate, but without contrasts. 

 The median vein is white or whitish, without contrast or obvious 

 margins. A black dot at the end of the cell. Transverse posterior 

 line reduced to two black points. A faint triangular cloud below 

 apex. A series of black terminal dots. Secondaries white. Beneath, 

 primaries yellowish, only a little powdered on the disk; secondaries 

 with powder}' costa and some black dots on the outer margin. 



Exijanse. — 1.46 to 1.56 inches (36.5 to 39 nmi.). 



TIahitat. — Los Angeles, California, April 16 (Howard); Los Ang-eles 

 County, in April (Koebele); Fresno, California (Schwarz); Sierra 

 Nevada (Henry Edwards). 



Five examples are under examination; all very much alike. The 

 species is an easily recognizable one with its very pale colors and 

 simple, obscure maculation. 



LEUCANIA PALLISECA, new species. 



Ground color a ver}' pale whitish yellow. Collar with three dusky 

 transverse bands. Primaries feebly and not contrastingly strigate, 

 all ordinary markings reduced to the vanishing point. Median vein 

 scarcely defined in any way. Discal dot minute or wanting. Trans- 

 verse posterior line consists of very small black dots and is never 

 complete; sometimes wanting. A series of minute terminal dots. 

 Secondaries pure white, immaculate. Beneath, white; primaries with 

 a creamy tint and a little tendency to darken on the disk; secondaries 

 a little powdery over the costal region. 



Expanse. — 1.25 to 1.45 inches (31 to 36 mm.). 



Ilahitai. — Los Angeles County, California, in July (LT.S.N.M.); 

 Fresno, California (Schwarz); Denver. Colorado, May and October. 



Seven examples are at hand and are about as nearly immaculate as 

 a species in this series can well be. Oddly enough, all the specimens 

 are females, and I was at first inclined to consider them iQ\\yA\Q foreta; 

 but I have that sex full}^ agreeing with the male, and therefore prefer 

 to consider this a good species. 



Type.—^o. 6251, U.S.N.M.
