Genus Sarata (females), Species 338-346: 

 S. alpJia to S. delta 



[The females are of a uniform pattern and similar coloration; the 

 ground color gray, sometimes tinted with pale brown and more 

 or less dusted with white, variations in color more individual 

 than specific; the transverse lines strongly contrasted, white with 

 strongly accented blackish or brownish borders on outer margin 

 of antemedial and inner margin of subterminal lines; the lines 

 oblique and straight or notched, the notching also more individual 

 than specific in character. The only reliable specific characters 

 are in the genitalia, and for certain identification it is necessary 

 to dissect nearly all females.] 



338. Sarata alpha, new species 

 Figure 888 



A bright species with the white lines and their black 

 borders sharply contrasted. Forewing blackish gray 

 with a strong dusting of white (however, in one speci- 

 men from the type locality, the median area distinctly 

 darker than basal or outer areas); antemedial line 

 slightly curved; subterminal line straight or with a very 

 slight bend at lower fold; discal dots distinct, more or 

 less confluent. Hind wing whitish with a faint brown 

 tint; the veins slightly darkened; a broadened blackish 

 brown line along termen; cilia white. Alar expanse, 

 21-24 mm. 



Female genitalia with bursa large and greatly elon- 

 gated; densely and finely spined over most of interior 

 surface, the denser spining in longitudinal rows, partial- 

 ly divided by lines of the clear membrane; anterior end 

 thickened (cartilaginous), the amount of thickening 

 individually variable; ductus bursae very short. 



Type locality: Oxbow, Saskatchewan, Canada (type 

 in USNM, 61358). 



Food plant: Unknown. 



Described from female type and two female paratypes 

 from the type locality, May 14, 1907, Frederick Knab; 

 and additional female paratypes as follows: One from 

 Aweme, Manitoba, Apr. 12, 1903. N. Griddle; one from 

 Kegina, Saskatchewan, June 5, 1907; and two from 

 Chimney Gulch, Golden, Colo., July, Oslar. A female 

 in the Rutgers Collection (C. H. slide No. 2186) from 

 Colorado identified as atrella also goes here. Needless 

 to say there is no trace on any of these females of the 

 hairy vestiture of the male of atrella. 



339. Sarata beta, new species 



Figure 889 



Similar to alpha except less glossy. Forewing duller; 

 less white dusting; transverse lines and their black 

 borders less strongly contrasted; discal dots obscured. 

 Hind wing dark smoky gray; the veins not darkened. 

 Alar expanse, 23-26 mm. 



Female genitalia like those of alpha in shape and 

 proportions except that spining covers appreciably less 

 of the bursa sinface, leaving half or more than half of 

 the latter membranous and unspined. 



Type locality: Colorado (type in USNM, 61359). 



Food plant: Unknown. 



Described from female type with only a state locality 



label; one female paratype from Custer County, Colo.; 

 and one female paratype from Chilcotin, British 

 Columbia, May 2, 1920, E. K. Buckell No. 137. The 

 two Colorado examples were in the Barnes and National 

 Museum Collections as females of atrella Hulst. 



340. Sarata gamma, new species 

 Figure 890 



This is the female figured in the Ragonot Monograph 

 (pt. 1, pi. 23, fig. 2b.) as a paratype of his dnopher- 

 ella. Its genitalia, here figured, are similar to those of 

 alpha and beta except for slight differences in the spining 

 of the bursa, as shown in the figure. 



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



Food plant: Unknown. 



341. Sarata iota, new species 

 Figure 894 



This name is proposed for the female paratype of 

 pullatella Ragonot, described and figured by him 

 (Monograph, pt. 1, p. 547, pi. 19, fig. 9b, 1893). 



Forewing blackish gray with very little pale dusting; 

 the antemedial line broader and more strongly con- 

 trasted than the subterminal. Hind wing dark grayish 

 brown. Alar expanse, 24 mm. 



Genitalia (C. H. slide No. 3113) with bursa consider- 

 ably smaller and more sparsely spined than that of any 

 of the preceding species; ductus bursae about half as 

 long as bursa. 



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



Food plant: Unknown. 



It is very likely that this is the female of pullatella; 

 but at the present time there is no certainty about any 

 of the sex associations in the genus. 



342. Sarata perfuscalis (Hulst)

 Sarata perfuscalis (Hulst), Phycitidae of N. Amer., p. 168, 1890. — 



McDunnough, Check list, No. 6269, 1939. 



Forewing dull, dark gray more or less dusted with 

 white ; the terminal and (usually) the median areas the 

 paler, the basal area the darker; transverse lines dis- 

 tinct, sordid white, their dark borders well contrasted, 

 especially on specimens with considerable white dusting. 

 Hind wing smoky grayish brown. Alar expanse, 25- 

 29 mm. 



Female genitalia distinguished by the spining of the 

 large bursa. These spines are arranged in an elongate, 

 ribbed band which extends most of the length of the 

 inner dorsolateral surface, curving onto ventral surface 

 at anterior end; the area of bursa under the spines more 

 or less sclerotized.
