spondents, who are hereby requested to correct the error; the type of 
orthiodes is from Burma, and still unique. 
Mesoihyrsa, n. g. 
Head with appressed scales, side-tufts loosely spreading ; ocelli present ; 
tongue developed, Antenne 2,in @ rather stout, simple, basal joint moder 
ate, without pecten. Labial palpi very long, recurved, second joint very 
long, densely scaled, with rough expanded hairs above towards apex, 
terminal joint in ¢ short, obtuse, flattened and somewhat concave internally, 
in Q 2, slender, acute. Maxillary palpi short, filiform, appressed to tongue, 
Posterior tibiz clothed with long hairs above, Forewings with 2 from towards 
angle, 8 and 9 out of 7, 7 to termen, 11 from middle, Hindwings 1, elongate- 
ovate, cilia + ; 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 wolopis, n. sp. 
& Q. 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 @ with apex of second joint and most of terminal except 
apex suffused with dark fuscous, in Q with a few dark fuscous scales. 
Antenne 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 3; 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 9 example 
shows less grey colouring than any of the @ @. 
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. 
&Q. 12-13 mm. Head and thorax ochreous-yellow. Palpi ochreous- 
yellowish, second joint rough-scaled above towards apex, apex dark fuscous, 
terminal joint in @ very short, in Q 3. Antenne pale yellowish ringed with 
fuscous, Abdomen whitish-yellowish, in Q dorsally suffused with grey. 
Forewings elongate, costa gently arched, apex tolerably pointed, more so in Q, 
termen nearly straight, in @ rather strongly, in very oblique ; 7 to apex ;
