268 Mr. Edward Meyrick's Description of 



fuscous. Fore-wings elongate, rather narrow, posteriorly dilated, 

 costa almost straight, moderately arched towards apex, apex obtuse, 

 termen nearly straight, somewhat oblique; dark fuscous; four 

 blue-leaden-motallic transverse streaks, first towards base, rather 

 thick, second beyond ^, slender, white on costa, third beyond middle, 

 not reaching costa, interrupted below middle, fourth submarginal, 

 slightly sinuate inwards below middle ; a white dot on costa before 

 §, edged beneath by a leaden-metallic dot, whence a fine straight 

 pale broAvnish line runs to dorsum at |; a slender pale brownish 

 streak along termen : cilia dark fuscous, round apex and upper 

 half of termen with basal half white (imperfect). Hind-wings dark 

 fuscous; cilia grey, with dark fuscous subbasal shade. 



British Guiana, Mallali, in March (Parish) ; one 

 specimen. 



Zalithia, Meyr. 



I had merged this in Strobisia, but now think it better to 

 maintain it as a separate genus; restricting Strobisia to 

 those species in which 7 of fore-wings is always absent. 



Zalithia euphracta, n. sp. 

 (^ $. 11-15 mm. Head and thorax dark green-bronze. Palpi 

 whitish-bronze, terminal joint dark purplish-bronze. Abdomen

 shaped marks from costa at \ and |, second sometimes prolonged

 submedian leaden-grey mark beneath first of these, sometimes 

 connected with a projection of lower angle of basal patch ; a some- 

 what oblique narrow median leaden-metallic blackish-edged fascia, 

 more or less dilated on dorsum, preceded by a variable orange band 

 extending to preceding markmgs but sometimes more or loss wholly 

 obsolete; a transverse blue-leaden-metallic line at J, white on 

 costa, nearly followed by a rather incurved white transverse line, 

 more or less leaden-metallic in disc, both terminated beneath by a
