AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



165 



Type locality: California {jperfuscalis, excantalis, in 

 AMNH, ex Rutgers). 



Food plant: Unknown. 



Distribution: California (state locality only); 

 Washington, Seattle; Utah, Eureka (Mar., Apr.), 

 Stockton (Apr.). 



Hulst associated his perfuscalis with dnopherella 

 Ragonot; and excantalis with pullatella Ragonot. So 

 much for superficial sex associations. Their genitalia 

 show the two females to be obviously conspecific. 



343. Sarata epsilon, new species 

 Figure 892 



The smallest of the female species. Similar in colora- 

 tion to perfuscalis except that the dark borders of the 

 transverse whitish lines are somewhat broader and more 

 strongly contrasted. Alar expanse, 19-21 mm. 



Female genitalia with bursa moderately large, evenly 

 and finely spined on anterolateral half and extreme 

 anterior end. 



Type locality: Yosemite, Calif, (type in USNM, 

 61360). 



Food plant: Unknown. 



Described from female type from the type locality 

 identified by Ragonot as a female of nigrifasciella and 

 bearing that name label in his handwriting and female 

 paratypes as follows: One from Colorado, Cockerell, 

 collector, identified by Hulst as atrella; two from Golden, 

 Colo., May, Dyar and Caudell Nos. 16252 and 16253, 

 and identified by Dyar as paratypes of caudellella; 

 seven from Chimney Gulch, Golden, Colo., June, 

 Oslar; and one from Fort Wingate, N. Mex., March. 

 Here also is referrable one of the two female paratypes of 

 nigrifasciella Ragonot in the Paris Museum (C. H, slide 

 No. 2891). 



Most of the foregoing examples show at least one of 

 the black discal spots. On each of the seven specimens 

 from Chimney Gulch, Colo., is a minute white spot on 

 discocellular vein between the black dots and on these 

 also there is some very dark brown shading on the 

 otherwise blackish borders of the white transverse lines. 



(the female paratype of ruhithoracella Barnes and 

 McDunnough); and five female paratypes from Fort 

 Wingate, N. Mex. March, Jime, July. Also before 

 me, but not included among the paratypes, is a large 

 female (26.5 mm.) from Denver, Colo., Apr. 1, 1904, 

 Oslar. On this specimen the patagia are more putty 

 white than rufus. Its genitalia, however, agree in 

 detail with those of typical phi from Arizona and New 

 Mexico. The species is uncomfortably close to epsilon. 

 It probably does represent the female of ruhithoracella 

 but the verification of that relation will have to wait 

 upon rearing evidence. 



345. Sarata kappa, new species 



Figure 887 



Forewing dull, as in beta, but with considerable white 

 dusting, rather evenly distributed ; the transverse lines 

 more irregular and their black borders more strongly 

 contrasted ; subterminal line with slight notches at vein 

 6 and lower fold; lower discal dot faint, but distinguish- 

 able. The thorax of the type is strongly shaded with 

 rufus-ocherous. Alar expanse, 23 mm. 



Female genitalia with bursa copulatrix very small 

 (the smallest of any of the Sarata species) ; the greater 

 part of its inner dorsal surface covered with a dense mat 

 of very fine spines. Ductus bursae as long as bursa. 



Type locality: Arizona (type in USNM, 61362). 



Food plant: Unknown. 



Described from a pseudotype of perjuscalis Hulst 

 from the Fernald Collection, bearing only a state 

 locality and numbered "7820." 



In coloration similar to phi except for the blackish 

 borders of the transverse lines of forewing. Dis- 

 tinguished from that and other species of the genus by 

 its genitalia. 



346. Sarata delta, new species 



Figure 886 



This name is proposed for the second of the female 

 paratypes of nigrifasciella Ragonot (in Paris Mus., C. 

 H. slide No. 3111) whose genitalia are here figured. 



344. Sarata phi, new species 

 Figure 891 



Thorax shaded with rufus ocherous. 



Forewing more evenly dusted with white; dark 

 borders of the transverse lines distinctly brownish ; dis- 

 cal spots obsolete, replaced by a faint, white line or spot 

 on the discocellular vein. Alar expanse, 23-27 mm. 



Female genitalia essentially like those of epsilon. The 

 figure shows the bursa twisted into a reverse position 

 from that of epsilon to show the somewhat greater 

 development of the thickened (cartilagenous) lateral 

 margin (a variable and probably only an individual 

 character). 



Type locality: White Mts., Ariz, (type in USNM, 

 61361). 



Food plant: Unknown. 



Described from female type from the type locality 



80. Philodema, new genus 



Type of genus: Sarata rhoiella Dyar. 



Tongue well developed. Antenna pubescent; shaft 

 of male slightly flattened and with a shallow sinus near 

 base, the latter containing some shghtly roughened 

 scales and a few, minute serrations. Labial palpus 

 porrect (as in Sarata but shorter). Maxillary palpus 

 vestigial. Venation as in Sarata except vems 4 and 5 

 of hind wing stalked for half or less than half their 

 lengths and cell a short one-third the length of wing. 

 Eighth abdominal segment of male with ventrolateral 

 hair tufts. 



Male genitalia as in Sarata except: More squat, 

 broader in proportion to their length; harpe short in 

 proportion to its width; no erect clasper; aneUus 

 strongly sclerotized, its central area developed into a 

 pair of produced, pointed, bladelike arms, the usual
