Zalithia autodesma, n. sp. 



cJ 2 • 10-11 mm. Head, thorax, abdomen leaden-grey, face whitish. 

 Palpi whitish, anterior edgo of terminal joint black. Forewings 

 elongate, rather narrow, oosta gently arched, apex obtuse, termen 

 obliquely rounded ; blackish ; markings leaden-metallic, tinged 

 pale bluish; a basal patch, narrow on costa but confluent with an 

 oblique-triangular costal blotcli beyond it, dilated downwards and 

 extended along dorsum to connect with median fascia; a moderate 

 fascia from middle of costa to beyond middle of dorsum, narrow on 

 costa and dilated dorsally, containing an oblique blackish striga in 

 disc ; a short fine oblique streak from costa at |, white on costa ; 

 an irregular transverse blotch from lower part of termen, reaching 

 more than half across wing : cilia blackish, round apex more or 

 less whitish-suffused with dark fuscous subbasal and apical shades. 

 Hindwings dark fuscous ; in J some long dark grey hairs lying 

 beneath costa on basal ^ : cilia grey, more or less whitish -tinged 

 towards tips. 



CoLOBiBiA, Call, 500 feet, May (Parish) ; thirty specimens. 

 Extremely near and similar to preceding, but certainly distinct 

 by different sexual characters of hindwings, and basal markings of 

 forewings. 



/ Zalithia auxiliaris, n. sp. 



S 2 . 10-11 mm. Head, thorax, abdomen dark fuscous. Palpi 

 dark fuscous, second joint very minutely (almost imperceptibly) 

 ribbed whitish. Forewings elongate, rather narrow, costa gently 

 arched, apex obtuse, termen obliquely rounded ; bronzy-blackish ; 

 markings metallic leaden-grey ; a basal patch occupying \ of wing, 

 edge nearly straight, direct, including an oval blackish spot in disc; 

 a fascia from middle of costa to beyond middle of dorsum, narrow 

 and white on costal edge, strongly expanded on dorsum, including 

 a transverse blackish mark in disc ; a direct transverse costal mark 

 at |, white on costa ; a transverse blotch from lower part of termen 

 reaching | across wing: cilia blackish, round apex whitish, with 

 blackish subbasal and apical shades. Hindwings dark fuscous ; 

 cilia grey. 



Colombia, La Crumbre, 6600 feet, May (Parish)-, six specimens. 

 Also extremely like the two preceding, but easily known by the 

 dark face, direct (not obli(]ue) costal mark at |, different basal 

 patch, and absence of sexual structures in hindwings. The three 

 species might, however, be readily passed as identical. 



Zalithia viridescens, n. sp. 

 J. 12 mm. Head, thorax light violet-leaden, face ochreous- 

 whitish. Pal[)i whitish-ochreous, suffused grey anteriorly. Abdomen
