angle, 8 and 9 out of 7, 7 to termen, 11 from middle. Hindwings 1, elongate- 

 ovate, cilia i ; 3 and 4 connate, 5 — 7 tolerably parallel. 



In palpi and general characters intermediate between Periacma and Crypto- 

 lechia, but differing from both in 9 of forewings rising out of 7. 



Mesothyrsa ceolopis, n. sp. 



ft $. 15-18 mm. Head and thorax pale ochreous-yellowish, sides of crown 

 somewhat mixed with fuscous, shoulders suffused with dark fuscous. Palpi 

 whitish-ochreous, in ft with apex of second joint and most of terminal except 

 apex suffused with dark fuscous, in 9 with a few dark fuscous scales. 

 Antennee pale yellowish. Abdomen whitish-yellowish, more or less sprinkled 

 with grey. Forewings elongate, costa gently arched, apex round-pointed, ter- 

 men sinuate, oblique ; light ochreous-yellowish ; markings purplish-grey mixed 

 with blackish-grey, variable in development ; a spot extending along basal 

 fifth of costa ; stigmata irregular, large or small, plical beneath first discal, 

 sometimes cloudy grey fascia? extending from both discal stigmata to dorsum, 

 second also connected with a blackish spot on costa at § ; a cloudy fascia along 

 termen, sometimes connected with both extremities of the preceding fascia : 

 cilia light ochreous-yellow, with grey spots above apex and on tornus. Hind- 

 wings whitish-ochreous, more or less suffused with light grey on margins ; cilia 

 whitish-ochreous. 



Palni Hills, 6,000 feet (Campbell) ; four specimens. The single $ example 

 shows less grey colouring than any of the ft ft . 



Cryptolechia, Zell. 



The genera Homosaces, Phaosaces, and Prosarotra are structurally, but ap- 

 parently not naturally, separable from Cryptolechia, and I have therefore in- 

 cluded all together ; the same differences of neuration and palpi occur also in 

 Periacma. 



Cryptolechia micracma, n. sp. 



ft 9. 12-13 mm. Head and thorax ochreous-yellow. Palpi ochreous- 

 yellowish, second joint rough-scaled above towards apex, apex dark fuscous, 

 terminal joint in ft very short, in 9 h Antennas pale yellowish ringed with 

 fuscous. Abdomen whitish-yellowish, in 9 dorsally suffused with grey. 

 Forewings elongate, costa gently arched, apex tolerably pointed, more so in 9, 

 termen nearly straight, in ft rather strongly, in 9 very oblique ; 7 to apex ; 

 deep ochreous-yellow, irregularly sprinkled with dark fuscous ; stigmata dark 

 fuscous, plical nearly beneath first discal ; a suffused dark fuscous spot on 

 costa at § ; an irregular terminal fascia of dark fuscous suffusion or irroration, 

 projecting beneath so as to touch second discal stigma : cilia ochreous-yellow. 

 Hindwings in ft pale yellowish, in 9 light grey ; cilia pale yellowish. 



Ceylon (probably low country) ; Khasis ; in July, three specimens. 



Cryptolechia vespertina, n. sp. 



ft 9 • 17-20 mm. Head, palpi, antennas f, and thorax dark fuscous, sides of 

 crown pale ochreous. Abdomen pale ochreous, dorsally tinged with grey. 

 Forewings elongate, costa gently arched, apex obtuse, termen almost straight,
