gnathos a short, slender hook arising from a thickened 

 base. Clasper of harpe broad, squarish. Aedeagus 

 rather short; penis armed with a single small thornlike 

 comutus. Vinculmn with terminal margin broadly and 

 evenly romided; in aU other species of the genus the 

 terminal margin distinctly concave. 



Type localities: Colorado (incandla, in USNM); 

 Stockton, Utah {aridella, in USNM). 



Food plant: Unknown. 



Distribution: Colorado; Utah, Stockton (May); 

 California, Inyo Coimty (May). 



The palest of the Sarata species, except tephrella Rag- 

 onot. The genitalia of the t3rpes of incanella and ari- 

 della are identical. 



Genus Sarata (males),' Species 331-337: S. atrella

Vestiture of labial palpi, head, and prothorax a mix- 

 ture of scales and long hairs. 



Forewing blackish gray; transverse lines whitish gray, 

 dull; the antemedial line obsciffe; sub terminal line 

 stronger, always distinguishable, bordered inwardly and 

 outwardly by black streaklets on the veins; discal spots 

 obsolete, obscured in the dark ground color; blackish 

 dots along termen confluent. Hind wing pale to rather 

 dark smoky fuscous, a thin dark line along termen. Alar 

 expanse, 30-33 mm. 



Male genitalia with uncus elongate, evenly tapering 

 to narrowly rounded apex. Apical process of gnathos 

 about half as long as uncus, ventrally flattened. Ele- 

 ments of transtiUa short. Penis armed with a single 

 strong comutus, as long as aedeagus, no supplemental 

 sclerotized plate. 



Type locality: "West Cliff, Colo, (type in AMNH, 

 ex Rutgers). 



Food plant: Unknown. 



Distribution: Colorado, Custer County, West Cliff, 

 and two specimens with only the state locahty. 



The species is easily distinguished by the hairy vesti- 

 ture not possessed by any other known species in the 

 genus. 



332. Sarata caudellella (Dyar), new combination

Megasis caudellella Dyar, Proc. Ent. Soc. Washington, vol. 6, 

 p. 110, 1904.— McDunnough, Check list. No. 6261, 1939. 



Similar to the foregoing species (atrella) except : With- 

 out hairy vestiture and with some flne white powdering 

 on the blackish gray ground color of forewing; the 

 transverse lines distinct, obhque and nearly straight; 

 antemedial line followed on costa and preceded at inner 



margin by obscure dark blotches; sub terminal hne bor- 

 dered inwardly by a continuous irregular blackish 

 shade, outwardly by a short, faint, dark streaking of 

 the veins; the veins otherwise not appreciably streaked; 

 discal dots faint, but usually distinguishable, more or 

 less confluent; dots along terminal margui weak, fused 

 into a faint blackish line. Hind wing pale brownish 

 gray, semilustrous; a dark line along termen. Alar ex- 

 panse, 28-32 mm. 



Male genitalia differ from those of atrella only in 

 trifling details. 



Type locality: Golden, Colo, (tj^pe in USNM). 



Food plant: Unknown. 



Distribution: United States: Colorado, Golden 

 (May); Washington, Grand Coulee (Apr.). Canada: 

 Saskatchewan, Oxbow (June); Manitoba, Aweme (Apr.), 

 Miniota. 



Close to but distinct from atrella, from which it is 

 distinguished chiefly by its smooth-scaled vestiture 

 and the strong contrast of the whitish transverse lines 

 of forewing, especiaUy the well-marked antemedial line; 



333. Sarata dnopherella Ragonot 

 Figure 402 



Sarata dnopherella Ragonot, N. Amer. Phycitidae, p. 11, 1887; 

 Monograph, pt. 1, p. 616, 1893. 



This and the two species following (nigrifasciella and 

 cinereella) are very close, separable only by minor color 

 differences and trifling variations in the genitalia of their 

 types. Such variations are more than covered in the 

 series of nigrifasciella and cinereella before me. I sus- 

 pect that the names represent nothing but color varie- 

 ties of one variable species; but am keeping them sepa- 

 rate until life-history information and more extensive 

 collections are available and more exact definitions of 

 species and possible races can be made. 



Ragonot's dnopherella is authentically represented 

 only by its type. His description and figure suggest a 

 grayish brown form suffused with blackish brown and 

 with the transverse lines very weakly contrasted and 

 poorly defined against the ground color. Alar expanse, 

 32 mm. 



Male genitalia with uncus broadly and blimtly tri- 

 angulate, evenly tapering to narrowly rounded apex. 

 Elements of transtiUa moderately long, slender (about 

 half the length of those of atrella) . Penis armed with a 

 single stout comutus, shghtly more than half as long 

 as aedeagus and preceded basally by a small, weakly 

 sclerotized patch. 



Type locality: California (type in Paris Mus.). 



Food plant: Unknown. 



Hulst (Phycitidae of N. Amer., p. 168, 1890) treated 

 dnopherella as a synonym of his perfuscalis and it so 

 appears in our fists. As perfuscalis was described from 

 a female the synonymising of the two names was 

 arbitrary and, under the circumstances, unwarranted. 

 Ragonot (Monograph, p. 616, 1893) very rightly ques- 

 tioned it.
