In this species the pectinations of the antennae exhibit the 

 branching peculiar to this genus more prominently than in 

 any species which I have seen. 



Zerenidae. 

 Ehodophthitus, gen. nov. 



Nearly allied to Icterodes and Vindasura, but with the pri- 

 maries more elongated, the secondaries considerably shorter, 

 and the palpi longer. Type R.formosus. 



54. Rhodophthitus fbrniosus, sp. n. 



Primaries above flesh-coloured, with yellow costal border 

 speckled with dull black, an oblique costal dash at basal 

 third, a spot at the end of the cell, a very irregular subapical 

 costal spot, and an oblique patch on inner margin near the 

 external angle dull black ; a grey streak at external angle ; a 

 faint indication of a brownish stripe connecting the subapical 

 costal spot with the internal patch : secondaries rosy pink, 

 with the outer half of abdominal area whitish, crossed by a 

 black patch ; several black spots in the cell ; a transverse 

 discocellular black spot : head black, antennae dark brown ; 

 collar saffron-yellow ; thorax flesh-coloured ; abdomen yellow, 

 irregularly spotted with black. Under surface rosy pink, 

 costa of primaries bright yellow ; spots as above ; pectus deep 

 rose-red ; knees of legs blackish, tibiae and tarsi greyish ; ven- 

 ter yellow at the sides, with lateral black spots. Expanse of 

 wings 2 inches. 



In general coloration this insect is extremely unlike other 

 Zerenidae ; but in neuration it scarcely differs from Icterodes. 



Larentiidae. 



55. Emmelesia sublutea, sp. n. 



Wings above shining sordid white, the basal area crossed 

 by three irregular arched slaty-grey stripes, prominent black 

 discocellular spots : primaries with the external third dark 

 grey, spotted with black ; a marginal series of black spots ; 

 fringe brown, whitish in the centre, spotted with black : se- 

 condaries with a lunulated ferruginous stripe just beyond the 

 middle ; external area snow-white, with the apex and an inter- 

 rupted submarginal series of spots black ; an almost marginal 

 series of ferruginous spots and a marginal series of black 

 spots connected by a slender undulating line; fringe whity 

 brown, becoming dark brown at apex : body brownish, with 

 lateral black spots. Under surface straw-yellow : primaries
