South American Micro-Lepidoptera. 19 



9. 14-15 mm. Differs from cJ as follows : head mostly ochreous ; 

 palpi whitish, second joint suffused with grey towards apex ; thorax 

 pale ochreous, partially mixed with grey; forewings greyish- 

 ochreous, paler or whitish-tinged anteriorly, sometimes strigulated 

 with fuscous; lower half of basal patch more or less mixed with 

 dark fuscous, remainder obsolete ; dorsal whitish blotch obsolete ; 

 other markmgs as in ^ : cilia suffused with pale ochreous. 



Ecuador, Huigra, 4500 feet, in June; Peru, Cliosica, 

 2800 feet, and Lima, 500 feet, in July and August (Parish) ; 

 forty-five specimens. The (^ is easily distinguished from 

 plebeiana by the costal tuft, dark thorax and basal patch ; 

 but the 9, which differs much in appearance from the (^, 

 would sometimes be very similar to obscurely marked 

 forms of that species. I have not, however, yet received 

 plebeiana from South America. 



Eiicosma procellosa, n. sp. 



cj $. 10-11 mm. Head, palpi, and thorax grey, more or less irro- 

 rated or suffused with ochreous-grey-whitish, palpi moderate, sub- 

 ascending, shortly rough-scaled. Abdomen pale greyish-ochreous. 

 Forewings elongate, posteriorly slightly dilated, costa slightly 

 arched, in ^ without fold, apex obtuse, termen slightly sinuate, 

 little oblique ; dark fuscous irrorated with whitish ; costa on 

 posterior half with five pairs of strigulae of whitish irroration, 

 first and third pairs emitting very oblique blue-leaden strigae, 

 second of these running to termen beneath apex, others with short 

 blue-leaden marks; a very undefined oblique patch of whitish 

 suffusion or strigulation from middle of dorsum reaching half across 

 wing, sometimes little indicated; ocellus margined laterally by 

 erect thick leaden-metallic streaks, and enclosing three black dots : 

 cilia fuscous, with dark fuscous basal line edged by whitish suffusion. 

 Hindwings with 3 and 4 stalked ; whitish-grey, veins and a suffused 

 terminal band fuscous ; cilia whitish-grey, with darker basal shade.

 and August (Parish) ; forty-two specimens. 



Eucosma evidens, n. sp. 



o ?• 12-15 mm. Head whitish-ochi-eous, forehead and collar
