REVISION OF MOTHS OF PRODOXINAE 27 



geticula; all of first, and dorsum of second and third segments covered 

 with short, appressed scales; venter of second and first with long, 

 erect, hairlike scales. 



Thorax: Loosely covered with hairlike scales. Wings fully scaled 

 and moderately broad; membrane with aculeae evenly scattered over 

 entire surface. Forewings 12-veined ; all veins normally separate; an 

 accessory cell present and of large size; base of medius divided within 

 discal cell, forming a large intercalary cell. Hind wings 8-veined; 

 all veins separate except 5 and 6 which may be separate, connate or 

 stalked, intercalary cell present; basal crossvein present between 7 

 and 8. Frenulum simple in all males except Parategeticula, where it 

 is absent; poorly developed or absent in the females. Legs typically 

 with a pectinate epiphysis on foretibia, absent in Parategeticula; 

 meso thoracic leg with two tibial spurs, metathoracic leg with four; 

 tarsal claws simple. 



Abdomen: Normally cylindrical in all males and laterally com- 

 pressed in all females except in Tegeticula synthetica where it is de- 

 pressed in both sexes. Seventh segment of all females strongly 

 sclerotized, elongated; seventh sternite largely devoid of scales, brun- 

 neous; eighth segment entirely enclosed within seventh. 



Male genitalia: Tegumen reduced and hoodlil^e, apex either evenly 

 rounded or with two setigerous lobes. Uncus and gnathos absent. 

 Vinculum large, V- or Y-shaped, sometimes with saccus greatly ex- 

 tended. Transtilla well developed, rigidly connecting the bases of the 

 two valves; expanded laterally to form a pah of lobe-like enlargements 

 (labides) which are fused to the bases of the valves. Juxta present, 

 usually forming an elongate shield. AneUus largely membranous, 

 with a pair of tiny, darkly sclerotized elements located near inner 

 bases of valves. Valves frequently with spiniferous tubercules; 

 cucullus usually unmodified, sometimes with a row of stout spines. 

 Aedeagus relatively simple and straight; cornuti absent. 



Female genitaUa: One genital opening present (monotrysia) . Ovipositor 

 of the piercing type; apex serrulate, usually spear-shaped; subapical 

 region of ovipositor frequently with a serrated, dorsal ridge ; anterior 

 and posterior apophyses usually slender and greatly elongated; 

 bursa copulatrix frequently with a pair of signa, each resembling a 

 stellate cluster; signa vestigial in some species or absent; oviduct 

 greatly lengthened; ductus bursa often enlarged to form a primitive 

 spermatheca. 



Larva. — Small, length at maturity usually less than 15 mm. 

 Head small, less than half diameter of prothorax; not depressed, 

 about as high as broad, sometimes partly retracted into prothorax. 

 Body typically stout and cylindrical, usually of a pale green, pink, 

 or white color; without prominent setae. Thoracic legs either present
