DESCRIPTIONS OF INDIAN MICRO-LEPIDOPTERA. 161 



dark fuscous. Forewings elongate, costa gently arched, apex obtuse, termen 

 faintly sinuate, oblique ; 7 to just below apex ; dark fuscous ; second discal 

 stigma and a suffused streak connecting it with tornus very obscurely darker : 

 cilia dark fuscous. Hindwings dark fuscous; cilia fuscous, with darker sub- 

 basal shade. 



Khasis ; in May, one specimen. 

 Periacma conophanta, n. sp. 



$$.14-16 mm. Head, palpi, antennas, thorax, and abdomen dark fuscous ; 

 lower part of face and base of palpi in $ suffused with whitish-ochreous, tip 

 of palpi in $ whitish ; anal tuft mixed with whitish-ochreous. Forewings 

 elongate, rather narrow, costa gently arched, apex obtuse, termen straight, 

 oblique ; 7 to apex ; dark purplish-fuscous ; stigmata obscurely darker, 

 plical rather beyond first discal ; a small triangular ochreous-whitish spot 

 on costa about £ : cilia dark fuscous. Hindwings dark fuscous ; cilia 

 fuscous. 



Madulsima, Peradeniya, Maturatta. Ceylon (Green, Pole) ; Khasis : from 

 March to September, ten specimens. 

 Periacma iodesma, n. sp. 



$ $ . 17-19 mm. Head and thorax orange. Palpi orange, second joint in $ 

 with dark fuscous streak anteriorly except towards base. Antennas grey, beneath 

 whitish-ochreous. Abdomen grey, anal tuft pale ochreous-yellowish. Fore- 

 wings elongate, costa gently arched, apex obtuse, termen obliquely rounded ; 

 7 to apex ; orange ; markings dark purplish-fuscous ; a dot on base of costa • 

 an irregular spot on base of dorsum ; a streak along fold from near base to 

 middle of wing, sometimes connected with preceding ; a rather elongate mark 

 above this, representing first discal stigma ; a rather narrow fascia from costa 

 beyond middle to dorsum before tornus, where it unites with a similar more 

 irregular-edged fascia running round apex and termen cilia orange, becoming 

 paler towards tips, beneath tornus grey. Hindwings grey ; cilia pale yellowish, 

 with indistinct grey subbasal shade. 



Khasis ; in May and June, twenty specimens. Closely allied to orthiodes 

 but the latter species is smaller and paler, and entirely without the dark fus- 

 cous streak on palpi of $ . Before recognising its distinctness I sent specimens 

 of the present species under the name of orthiodes to some of my corre- 

 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 presont ; 

 tongue developed. Antennas §, 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 $ |, slender, acute. Maxillary palpi short, filiform, appressed to tongue. 

 Posterior tibiae clothed with long hairs above. Forewings with 2 from towards
