Genus 34: Rampylla 



[Male: Venational division D. Transtilla present but variously 

 modified. Harpe with apex of sacculus produced, strongly 

 sclerotized and pointed. Hind wing triangulate; anal angle 

 folded and produced; sex tufts and scalings on lower surface. 

 Female: Venational division B. Bursa and ductus bursae 

 simple; ductus seminalis from bursa. Hind wing with cell one- 

 third the length of wing.] 



34. Genus Rampylla Dyar 



Rampylla Dyar, Ins. Insc. Menstr., vol. 7, p. 84, 1919. (Type 

 of genus: Rampylla orio Dyar). 



Tongue well developed. Antenna pubescent; shaft 

 of male slightly thickened. Labial palpus upturned, 

 not reaching vertex in male, a trifle longer in female; 

 second segment slightly rough scaled beneath; third 

 segment bluntly acuminate, about half the length of 

 second (shorter on male than female). MaxiQary 

 palpus squamous, small. Forewing smooth except for 

 a sHght, projecting scale tuft from inner margin near 

 base on male; 11 veins; vein 2 from before lower outer 

 angle of cell; 3 from the angle, well separated from 2; 

 4 and 5 approximate at base and for a very short dis- 

 tance beyond; 6 from below upper angle of cell, straight; 

 10 from the cell; male without costal fold. Hind wing 

 with vein 2 from before the lower outer angle of cell; 

 3 from the angle and in the male almost as long as vein 

 2; in the female considerably shorter; 4 and 5 very 

 shortly stalked or contiguous for a short distance from 

 cell, connate with 3 ; 7 and 8 contiguous or closely ap- 

 proximate for a short distance from cell; cell in male 

 one-fourth the length of wing, in female approximately 

 one-third; discocellular vein curved; on male anal area 

 (involving vein la) thickened and folded, forming a 

 produced pocket, enclosing a long hair pencil; under- 

 side of male wing with roughened scale or hair tufts on 

 some of the veins. Eighth abdominal segment of male 

 with sternite developed as a narrow, sclerotized pocket. 

 Metathorax of male with a stout pencil of spatulate 

 scales from just above base of leg. 



Male genitalia with transtilla present, variously modi- 

 fied (greatly reduced in lophotalis). Harpe with sac- 

 culus produced into a strong free hook at apex. A long 

 free spine associated with anellus (as in the four preced- 

 ing genera). 



Female genitaUa with bm-sa more or less finely scobin- 

 ate and with some concentration of these fine scobina- 

 tions but no definable sigmmi; ductus bursae simple, 

 short (shorter than bursa except in lophotalis). An 

 invaginated, sclerotized, dorsal pocket at apical end of 

 seventh abdominal segment or (in lophotalis) a sclero- 

 tized, granulate, dorsal pocket between ovipositor and 

 eighth-segment coUar. 



The length of vein 3 in proportion to 2 of hind wing 

 places the males in our venational division D and, in 

 conjunction with their decidedly triangulate hind wings 

 and the sex-scalings and tuf tiogs on their imder surfaces, 

 readily distinguishes the genus. The females on hind 

 wing venation fall into division B. The four species 

 here recognized are all tropical American. They ex- 



hibit distinct specific differences in genitaha, color, and 

 maculation. The transverse lines of forewing, in their 

 rather close approximation and narrow black borders, 

 are similar to those of Coptarthria to which Rampylla 

 seems most nearly related.

 Rampylla orio Dyar, Ins. Insc. Menstr., vol. 7, p. 84, 1919. 



Forewing violaceous gray; under magnification ex- 

 treme base and a rather broad area along inner margin 

 to beyond middle tinted with purplish red; antemedial 

 line obsolete; sub terminal line narrow, blackish, rather 

 close to and nearly parallel with termen, vertical from 

 costa to vein 8, inwardly angled between veins 8 and 5, 

 thence obhque to ioner margin, bordered iawardly by a 

 faint ocherous shade and outwardly by a narrow ocher- 

 ous line; discal dots at end of cell separate, ocherous; a 

 thin dark line along terminal margin. Hind wing trans- 

 lucent white with a fuscous shade at apex and anal area 

 yellow; veins not appreciably darkened; terminal mar- 

 gin darkened only towards apex; on underside of hind 

 wing (male) a yeUow hair tuft at origin of veins 4 and 5 

 from cell; a white fringe continuing outwardly on these 

 veins and a similar white fringe on vein 7 above the 

 yellow hair tuft. Alar expanse, 22 mm. 



Male genitalia with lateral portion of uncus on each 

 side produced iato a broad, strongly sclerotized, projec- 

 tion armed at apex with a cluster of long, slender, strong, 

 black spines. TranstiUa produced caudally iato a bi- 

 lobed, scobinate process fusing with reduced arms of 

 gnathos. Tegumen with a long, stout, curved, free arm 

 arising from base at each ventrolateral angle. Harpe 

 with produced sacculus developed as a long, stout, taper- 

 ing hook, curved across face of harpe. Anellus heart- 

 shaped; associated spine straight. Aedeagus partially 

 sclerotized; penis with some farat, sclerotized wrinklings 

 and a few microscopic scobinations, otherwise unarmed. 



Type localitt: Zacualp^n, M6xico (type in USNM). 



Food plant: Unknown. 



Known only from the male type.

Forewing brownish gray with a faint purplish tint; a 

 narrow border along inner margin between the trans- 

 verse lines and a somewhat broader area along termen 

 dusted with duU, grayish white; antemedial line narrow, 

 faint, pale gray, indicated chiefly by its narrow, black 

 outer-bordering hne, the line well out towards middle of 

 wing and shghtly sinnous, nearly vertical; subterminal 

 line equally thin and pale gray with a similar black inner 

 border, angled outward slightly at middle and nearly 

 parallel with termen; a black line along terminal margin; 

 discal spots small, confluent, ocherous; faint indication
