bright color and characteristic markmgs of the wiiigs, might be 

 compared only with the species of the tortricid genera Atteria Walker 

 (tribe Anacrusiini) and Idolatteria Walsingham (tribe Archipini). 

 The external morphological characters, like the long labial palpi and 

 the vein R5 of the forewing leading to the wing apex, make the 

 separation of the Pseudatteria species from these two genera very- 

 easy, and the genitalic characters permit their recognition at once as 

 members of the tribe Polyorthini. 



Both male and female genitalia provide the bases for a division of 

 the genus Pseudatteria into three subgenera, Pseudatteria Walsingham, 

 sensu stricto, Eurynatteria, new subgenus, and Sj^haer atteria, new 

 subgenus, as they are defined m this paper. Only the external 

 morphological characters, common in all three of the above subgenera, 

 restrain the present author from raising them to the generic status. 



In respect to the markings of the wmgs the Pseudatteria species 

 might be divided mto fom' groups, independent from the subgeneric 

 division: 



1. Markings of forewing consist of more or less broad, black 

 marginal streaks, variously numerous, and perpendicular or slightly 

 oblique to costa and termen; no spots on dorsum; some occasional, 

 scarcely developed spots in internal area of forewing; subcostal area of 

 forewing white, variously broad; apicoterminal portion of forewing 

 also white, very broad; remaining portion of forewing and hindwing 

 orange; latter with some white in cilia only and with black spots on 

 margins; no internal spots on hindwing {volcanica Butler; splendens 

 Druce; cladodes Walsingham; bradleyi, new species; chrysanthema 

 Meyrick; igniflora IVIeyrick; shaferi, new species; dognini, new species; 

 tremewani, new species; maenas Meyrick; and pseudomaenas, new 

 species) . 



2. Black marginal streaks of forewing as in former group, in some 

 species narrower and more numerous; as a rule spots on dorsum present; 

 internal area of forewing generally with very numerous and well- 

 developed spots; white subcostal area of forewing almost as broad as 

 in group 1, or narrower to completely lacking; white apicoterminal 

 area of forewing always narrower or lacking; hindwing with spots on 

 margins and in internal area {symplacota Mejnck -ffumipennis Dognin; 

 ardoris, new species; leopardina Butler; marmarantha Meyrick; 

 myriocosma Meyrick; unciana Dognin; pantherina Felder; heliocausta f. 

 baccheutis Meyrick). The nominate form of heliocausta Dognin shows 

 the characters intermediate between the two groups, having on the 

 forewing no dorsal spots and no or only some occasional, internal 

 spots, and the hindwing well spotted in the internal area. 



3. Dark markings of forewing confluent, leaving ground color of
