of). Perizoma semifusca sp. nov. 



Forewiihjfi : orhreous grey, tinged in parts with rufous ; a narmw central bhitkish 

 fascia edged with lilack lines, and with a black line down its centre ; the inner edge 

 evenly curved, the outer indented opposite the cell, and with a slight bilobed projection 

 between the first and third medians; basal space within this fascia traversed by 

 i?everal curved lines, and suffused with dull reddish grey ; basal i>atch itself fuscous 

 or blackish; a reddish band in the space between it and the central fascia; the 

 outer edge of central fascia is itself edged by a white line, followed by two wavy dark 

 lines ; submarginal shade cuneiform, a double blackish wedge-shaped mark oppiosite 

 the cell ; extreme hindmargin fuscous and reddish, with a jialer patch in middle, as 

 in faeninta ; fringes reddish grey mottled with darker. 



Ilindwlnrjs : dull ochreous grey, with broad curx'ed dark grey marginal band 

 and traces of curved lines in the central portion of the wing. 



Thorax and abdomen blackish; anal segment iu S pale; vertex, palpi, and face 

 pale grey. L'nderside dull greyish, with a broad pale submarginal fascia beyond 

 exterior edge of central fascia; base of hindwings paler. 



Expanse of wings : ? , 20 mm. ; <?, 18 7nni. 



Several from the Khasias. 



Generally, owing to the dark suffusion of the space between the basal patch and 

 central fascia, the whole basal three-fifths appears dark, while the outer two-fifths 

 remains in the main of the pale ground-colour, and by this the insect may be easily 

 recognised. 



57. Perizoma tenuifascia sp. nov. 



Forevrlngs: greyish white, with a narrow basal patch and slender central fascia 

 brown; the fascia is liroader on costa. and has a small p)rojection on its outer edge 

 below the median ; a small brown costal spot before apex ; a blackish discal spot in 

 central fascia ; marginal line dark grey ; fringe whitish, with dark grey triangular 

 mottlings. 



Ilindiviiii/S : greyer, with a faint central curved line. 



Head and thorax dark grey-brown, the metathorax black ; abdomen greyish 

 white, with black band on first segment and black spots on back of the rest.

 traces of two curved lines. 



Expanse of wings : S , -4 mm. ; ? , 20 mm. 



Both .sexes from the Khasias. 



It is possible that this and iri}Aiif/i<i{(i. may be forms of the same species : tri- 

 fjlar/'KUa has an ochreous .suffusion which is wanting in teiiuifancid ; and the specimens 

 were taken a month later than those of the latter — in October, instead of .September.
