vein curved, outwardly produced at lower angle of cell. 

 Eighth abdominal segment of male with a pair of weak, 

 ventrolateral hair tufts. 



Male genitaUa with uncus triangulate, its apex 

 rounded. Apical process of gnathos terminating in an 

 elongate hook, moderately long and bladelike (except in 

 incanella where it is short, and digitate from an enlarged 

 base) ; lateral arms of gnathos broad and stout. Trans- 

 tilla incomplete; its lateral elements well sclerotized and 

 short or moderately long and slender, their apices 

 pointed. Harpe, elongate, slender; apex of cucuUus 

 rounded; clasper present as a very short, blunt, wartlike 

 projection from near middle of basal margin of cucuUus 

 (except in incanella where it is broader and more scoop- 

 like), the size and shape of the wartlike clasper indi- 

 vidually variable; costa not produced, strongly sclero- 

 tized only on basal half. Anellus a shallow, broadly 

 U-shaped shield. Aedeagus long, straight, not appre- 

 ciably tapering or expanded towards apex, stout to 

 moderately slender (incanella) ; penis (except in incan- 

 ella) armed with a single, long, stout, spikelike cornutus, 

 rarely a second elongate slenderer spine (on penis of 

 incanella the single cornutus is a short, stout thorn sit- 

 uated near apex). Vinculum stout, as long as or but a 

 trifle longer than broad; terminal margin broad. 



Female genitalia with bursa strongly scobinate over 

 much of inner surface and more or less thickened 

 (cartilaginous) at or near anterior end; ductus bursae 

 simple (unsclerotized and imspined throughout), nor- 

 mally distinctly shorter than bursa; ductus seminalis 

 from bursa near its middle well forward of junction of 

 bursa and ductus bursae). 



The species here referred to Sarata form a homogene- 

 ous group. Some of them on the basis of a smooth 

 male antennal shaft have hitherto been listed imder the 

 Old World genus Megasis; but none agrees with the 

 type of the latter (rippertella (Zeller), fig. 428) on 

 genitalic characters or the stalking of veins 4-5 of hind 

 wing, which is always shorter (and frequently incom- 

 plete, a mere approximation or anastomosis of the basal 

 half of the veins in rippertella) . The difference between 

 a smooth antennal shaft and one with some roughened 

 scales towards base is very slight, and should have no 

 weight against the uniformity of the genitalic and vena- 

 tional characters of Sarata otherwise. Indeed the 

 species of Sarata are much closer to those of Lipographis 

 than to the type of Megasis. 



None of om- species has been reared and nothing is 

 known of the food plants of any of them, so that any 

 association of females with males is purely speculative. 

 Such associations as have been made are open to grave 

 suspicion. The females differ from the males not only 

 in size but also in pattern and color, and within any 

 given species of females the color varies more between 

 individuals than it does between the species themselves. 

 For this reason I have treated the males and females 

 separately, giving to the latter new temporary names 

 which can go into synonymy when the sexes are properly 

 associated. 



UNITED STATES NATIONAL MUSEUM BULLETIN 207 



The following three species hitherto listed in Megasis 

 or Sarata must be referred elsewhere: 



Sarata rhoieUa Dyar becomes the type of a new genus 

 (Philodema) . 



Sarata umbrella Dyar goes to Lipographis. 



Megasis indianella Dyar is an anerastiine and a 

 synonym (see p. 315) of Bagonotia oliveUa (Hulst). 



Genus Sarata (males), Species 326-330: 

 S. edwardsialis to S. incanella 



[Antennal shaft at base smooth scaled.]

list, No. 6259, 1939. 



Forewing pale grayish brown more or less smudged 

 with darker gray; blackish streaks on several of the 

 veins, especially marked on vein lb, the lower vein of 

 cell, and the veins immediately preceding and following 

 the sub terminal line; the latter faintly indicated; ante- 

 medial line obsolete; discal spots poorly defined, often 

 obliterated, where distinguishable, separated; a row of 

 narrow black dots along termen, more or less accented. 

 Hind wing a little lighter grayish brown than ground 

 color of forewing, the veins not appreciably darkened, 

 a slightly darker line along termen; cilia paler, a dull 

 white with a faint fuscous tint. Alar expanse, 35-46 

 mm. 



Male genitalia with uncus evenly tapering to narrowly 

 rounded apex. Apical process of gnathos about half as 

 long as uncus. Elements of transtilla very short. 

 Aedeagus long, stout; penis armed with a single, straight 

 cornutus, nearly as long as aedeagus, also a small sup- 

 plemental sclerotized patch. Terminal margin of vin- 

 culum concave. 



Type localities: Nevada (edwardsialis, in AMNH, 

 ex Rutgers); California (polyphemella, in Paris Mus.). 



Food plant: Unknown. 



Distribution: Colorado, Boulder (Mar.), Glenwood 

 Springs (Mar., Apr.), Salida; Utah, Dividend (Mar.), 

 Eureka (Apr., May) ; Nevada; California, "Middle Cali- 

 fornia"; Washington, Grand Coulee (Apr.), Pullman 

 (Apr.). 



Average specimens (40 mm. or more) make this the 

 largest species in the genus. The Ragonot figure of 

 polyphemella (Monograph, pi. 19, fig. 8a) is a very good 

 likeness of normal examples, except that hind wing is a 

 trifle too dark.

Smaller on the average than edwardsialis and darker.
