outer edge. Fore and middle tibise and tarsi reddish. Eeneatli fore 

 wines pale, deeper green on the costal half; basal two-thirds of costa 

 deep red. Hind wings whitish green. The outer line on fore wings 

 faintly reappears. Abdomen wanting. 



Length of fore wing .40 inch. California (Edwards). 

 Chlorosea * n. gen. 



Belonging apparently to the same group as Nemoria and Eunemo- 

 ria, and less closely to Phorodesma. Head with the vertex not so 

 broad in proportion as in Nemoria or Pseudoterpna ; front moderately 

 broad, less so, however, than in Nemoria. Palpi rather long and 

 slender, projecting farther than usual beyond the front (though not 

 nearly so much so as in Synchlora}, slightly ascending; third joint 

 small, but distinct. Antennas pectinated almost to the tip ; branches 

 about half as long in proportion as in Nemoria', in 9 slender and 

 filiform. Fore wings shaped much as in Nemoria, costa curved in 

 the same manner, apex subacute, outer edge curved in much the 

 same way. The costal space is slightly narrower in proportion than 

 in Nemoria, and the fifth subcostal or subapical space is small, being 

 one-fourth as long as the wing, while in Nemoria it is much larger, 

 being one-third as long as the costa of the wing. Hind wings of 

 much the same shape as in Phorodesma and Pseudoterpna, not being 

 produced and subangulated, as in Nemoria, or so long and fully 

 rounded, as in Eunemoria; the apical region is full and rounded, 

 while the outer edge is very straight. The abdomen does not reach 

 the anal angle of the hind wings; its shape is much as in Nemoria. 

 Hind legs unusually small, tibiae very slender and short, shorter than 

 the tarsi, and with but a single terminal pair of spurs in both sexes. 

 No essential difference between the sexes. 



Coloration much as in Nemoria. The known species are of larger 

 size than usual in the allied genera. 



Palpi less ascending than in Nemoria, antennae one-half as widely 

 pectinated, but wider than in Eunemoria. The hind legs are much 

 as in Phorodesma, but there is but one pair of spurs, and the vertex 

 is not so broad as in that genus, while the antennae are pectinated 

 nearer the tip. 



Chlorosea Nevadaria n. sp. l <s , 2 ?. 



Pale pea green. Head whitish at the insertion of the antennae 

 (which are white above), but greenish on the hinder edge of vertex; 

 front pale greenish, pink on the orbits ; palpi whitish ; thorax green ; 



i KAwpd?, green ; o-rjs, moth.
