rather dark fuscous suffusion along basal third of costa ; stigmata blackish, 

 plical rather before first discal, an additional dot beneath second discal ; a 

 spot of rather dark fuscous suffusion on middle of costa, reaching second dis- 

 cal stigma ; a moderately broad rather dark fuscous terminal fascia, rather 

 prominent in disc so as to touch second discal stigma and dot beneath it : cilia 

 ochreous-yellow, on tornus fuscous. Hindwings grey ; cilia whitish- yellowish, 

 tinged with grey towards base. 



Khasis ; in June, four specimens. 



Leptosaces makea, n. sp. 



$ 9. 15-17 mm. Head and thorax whitish-ochreous. Palpi ochreous- 

 whitish, second joint brownish or fuscous except apex. Antennae whitish- 

 ocbreous, dotted with fuscous except towards base. Abdomen whitish-ochre- 

 ous tinged with grey. Forewings elongate, rather narrow, costa gently arched, 

 apex obtuse, termen very obliquely rounded ; whitish-ochreous : cilia con- 

 colorous. Hindwings grey ; cilia ochreous-whitish tinged with grey towards 

 base. 



Cuddapah, 4,000 feet (Campbell) ; three specimens, 



Periacma, Meyr, 



The original diagnosis should be corrected or extended in the following 

 particulars. Antennae i to nearly 1, in £ simple, rather thick. Labial palpi 

 in $ with basal joint somewhat lengthened, second joint greatly elongate, 

 moderately stout, smooth-scaled, pointed, terminal joint absent, in $ with 

 second joint normal, long, terminal as long as second or shorter, slender, 

 acute. Forewings with 2 and 3 sometimes stalked, 7 to apex or sometimes 

 termen. 



Having now plenty of material for dissection, I find that the £ palpi are 

 really two-jointed, the greatly elongate joint, which I supposed to be the 

 terminal, being really the second, whilst the terminal is wholly absent ; when 

 the palpus is denuded, there appears to be not even a rudiment of it. The 

 long second joint, though somewhat pointed, is not slender, and acute like the 

 true terminal. As further evidence that it is really the terminal joint which 

 is absent, it may be noticed that in such species as scrupulosa and metrica, 

 where the second joint in the 9 bears a black subapical ring, this same ring 

 will be found in the £ beneath the apex of the elongate joint, clearly indi- 

 cating its homology. This curious palpus, which is unique and cannot be 

 mistaken for that of any other Lepidoptera, is alike in all the nineteen de- 

 scribed species, and forms the distinguishing mark of the genus. Besides 

 the three species previously described, Phceosaces torricla, Meyr. is properly 

 referable here. 



Periacma contraria, n. sp. 



£ 15 mm. Head, palpi, antennae, and thorax whitish-ochreous. Abdomen 

 pale gi'ey^ anal tuft whitish-ochreous. Forewings elongate, costa gently arched, 

 apex round-pointed, termen extremely obliquely rounded ; 7 to termen ; 

 whitish-ochreous, anteriorly tinged with yellow-ochreous, with a few scattered
