at end of cell ; a transverse blotch extendiug from beyond these to 

 dorsum before tornus ; an irregular almost apical spot : cilia grey, 

 basal third on termen suffused with whitish. Hindwiiigs grey ; 

 costal margin expanded to beyond middle, with long rough pro- 

 jecting hairscales suffused with dark grey beneath, and long whitish 

 subcostal hairpencil lying beneath forewings ; cilia whitish, with 

 grey basal shade. 



Eritish GuiiNA, Bartica, in January (Pa risJi)- two specimens. 

 At_ first sight much like inquinula, but the basal markings are 

 quite different. 



Antaeotricha mesostrota Meyr. 



6 2 • 17-21 mm. Extremely like pseudoeliyta, but ^ consider- 

 ably larger, veins 8 and 9 of forewings constantly separate, and the 

 discal black spot does not project beyond anterior margin of post- 

 median fascia. In $ there is a grey spot on posterior extremity 

 of thorax, and the hindwings are grey. There is a minute black 

 dot beneath posterior extremity of discal spot, sometimes touching 

 it, and a faint spot of grey suffusion above middle of disc ; the 

 fuscous suffusion forms a fascia round posterior part of costa and 

 termen, leaving edge beyond blackish proemarginal dots white. 



British Guiana, Bartica and Mallali, from December to March 

 (Parish); five specimens, agreeing entirely with the original 

 example from V'enezuela. 



Antaeotricha pseudocliyta, n. sp. 



S 13-15 mm., $ 16-19 mm. Head and thorax white, in $ 

 more or less suffused with grey. Palpi white, second joint more 

 or less suffused with grey except towards apex. Antennal cilia- 

 tions of S 2|. Abdomen whitish, in $ greyish-tinged. Forewings 

 elongate, costa moderately arched, apex rounded, termen rounded 

 somewhat oblique, dorsum rather expanded from base to | ; 8 and 

 9 long-stalked ; white ; a fuscous blotch composed of two confluent 

 spots occupying costa from near base to beyond |, sending two 

 oblique irregular partially obsolete lines across wing ; in $ dorsal 

 area much suffused and blotched wuth grey, and a blotch of faint 

 grey suffusion above middle of disc ; a strong oblique-longitudinal 

 blackish spot on upper angle of cell, and a dot beneath its posterior 

 extremity ; an irregular curved oblique narrow interrupted fuscous 

 fascia beyond this, slender on costa in c? , more developed in 5 , 

 discal spot strongly projecting from its anterior edge ; some fuscous 

 suffusion towards apex, in $ forming a broader fascia round apical 

 part of costa and termen, leaving a toothed white marginal line 

 with interspaces dark fuscous : cilia white, with three fuscous 

 shades, in c? nearly obsolete except round apex. Hindwings 

 in c? whitish, posteriorly greyish-tinged, in $ grey ; costal margin 

 in (S expanded to beyond middle, with long rough projecting 

 hairscales suffused with grey beneath, and long pale yellow- 

 ochreous subcostal hairpencil lying beneath forewings ; cilia white, 

 with two grey lines, in J obsolete except at apex.
