and 3 stalked; base of M simple in cell of both wings; anal veins as in 

 Cryptothelea, base of lA partially atrophied; 3 A usually continuing 

 toward hindmargin after separating from 2A as faint spur. Second- 

 aries with 8 veins; Sc + Rj and Rs either anastomosing at a point or 

 connected by cross vein midway along discal cell, continuing as parallel 

 veins to margin; M2 and 3 either connate or shortly stalked. 



Male genitalia. — Tegumen broadly acute, apex entire. Valves 

 with pulvilli well developed, minutely spined; sacculus with few 

 minute spines at apex. Vinculum rectangular, abruptly constricted 

 to form elongate, slender saccus. Aedeagus simple, without basal 

 expansion. Eighth sternite with stout divergent furcations. 



Female. — Body vermiform, all external appendages vestigial. 

 Head and dorsum of thorax shghtly sclerotized. Body naked except 

 for anal tuft. 



Female genitalia. — (Fig. 303.) Two pairs of apodemes present; 

 posterior pair slender, extending into apical segment of abdomen; 

 anterior pair within penultunate segment, basal portion rodlike, 

 remainder expanded into broadly sclerotized areas, extending ven- 

 trally, uniting near ostium. Internal genitaha with bursa enlarged, ex- 

 ceeding volume of spermatheca several times; ductus seminahs short 

 (less than length of bursa), stout; accessory glands bifid, well devel- 

 oped, arising from vestibulum. 



Discussion. — This genus closely resembles Lumacra both in general 

 appearance and in the structure of the male genitalia, but it differs 

 from that genus in the loss of the epiphysis and in the basal origin of 

 the antennal pectinations. Another feature of the antenna that 

 characterizes this genus is the very short rami, which has suggested 

 the name "Curtorama." Curtorama also superficially resembles the 

 predominantly North American genus Astala, but it differs primarily 

 from the latter by the retention of Mi in both wings.
