20. Bombycia simicircularis griseor, new variety. 



Female. — Patagia dark, not light gray as in the type" forms; primaries 

 more suffused with smoky gray, lines indistinct ; white basal patch and apical 

 shade rendered less prominent by dark scaling, former almost obsolete. Sec- 

 ondaries dark buff, with broad marginal border of smoky gray. 



Expanse, 40 mm. 



Habitat. — Verdi, Nev. (May), i female. Type, Coll. Barnes. 



This distinct form is probably the southern race of scmicircidaris 

 Grt. We might add that Cymatophora tcma Stkr. is a synonym of 

 scmicircidaris Grt. ; we have compared a specimen with both types 

 and find them identical.

21. Euclea flava, new species. 



Female. — General ground-color of body and wirigs ochreous yellow ; pri- 

 maries slightly darker in central portion ; in basal half of wing an irregular 

 thin white line extending from cubitus inwardly to near inner margin, sharply 

 angled at point of origin and followed by a darkish yellow shade ; near the 

 apex of wing a straight white dash extending from costa to vein Mj ; fringes 

 slightly darker than other portions of wing; secondaries uniform light yellow- 

 ocher ; beneath light ocher with costa and outer margin somewhat deeper 

 yellow. 



Expanse, 24.5 mm. 



This species is most nearly related to E. dolliana Dyar, but is at 

 once recognized by its light color and the faintness of the white 

 markings. In outward appearance it greatly resembles Adoncta v. 

 leucosigma Pack, but differs in venation, possessing all 12 veins. 



Habitat. — Babaquivera Mts., Arizona. i female. Type, Coll. 

 Barnes. 



22. Natada nigripuncta, new species. 



Male. — Collar reddish ochreous, thorax somewhat lighter, abdomen pur- 

 plish brown ; antennae and coxae with white patches at base ; primaries silky, 

 light purplish brown at base, much lighter, more ochreous, along costa towards 

 apex ; slightly sprinkled with minute black dots and with a black patch just 

 beyond origin of veins 3-5 ; hind wings uniform purplish brown. Beneath, 

 primaries light brown, whitish along inner margin ; secodaries ochreous 

 speckled with black dots. 



Expanse, 25 mm. 



This species agrees in venation with a specimen of Sisyrosca 

 tcxtida Grt. examined by us, having on primaries veins R., R3 and R,
