triangular spot is nearly black ; both wings with an elliptical 

 black discal spot, with silvery centre. 



Expanse of wings 22 millim. 



A good series from the Khasias. 



Pharambara costiscrtpla, sp. n. 



Fore wings dull yellowish ochreous, with dull red-brown 

 markings, which are restricted to the costal half; costa more 

 yellowish in the intervals and minutely spotted with brown ; 

 a brown blotch along costa near base, a subquadrate one 

 before middle, separated by a distinctly paler rather 

 glossy pear-shaped space from the outer blotch, which is 

 irregularly quadrate, and contains a pale rectangular mark 

 from the costa ; a smaller blotch before the apex throws off a 

 fine curved brown line, which runs near and parallel to hind 

 margin as far as the anal angle ; in the inner half of the wing 

 only dull reticulations can be traced ; fringes concolorous. 

 Hind wings with the costal area pale whitish ; the rest of 

 the wing with red-brown broken fascias and reticulations, 

 which more or less run into each other. Underside brighter, 

 with darker tessellations ; subcostal nervure and nervules of 

 fore wings with glistening black metallic scales. 



Expanse of wings 24 millim. 



One female, Queensland. 



The species can be distinguished by the pale pear-shaped 

 space depending from the costa between the two central 

 fascias. The fore wings are long and narrow, with bluntly 

 rounded apex and simply curved hind margin, and the hind 

 wings are comparatively small. 



Pharambara decoratalis, sp. n. 



Fore wings along inner margin pale whitish ochreous, 

 towards the hind margin becoming smoky fawn-colour ; costa 

 in its apical half bright tawny, from the base outwards 

 purplish fuscous, with numerous small coalescent blotches ; 

 the tawny exterior half of costa contains four pearly-grey 

 blotches, each with a central dark spot, and gradually de- 

 creasing in size towards apex, much as in many Tortrices • 

 along the middle of the marginal fawn-coloured space are 

 a few dark spots and one prominent black one close to 

 margin ; this fawn-coloured space throws out a short fascia 

 to inner margin before anal angle, the angle itself remaining 

 pale, with a small triangular grey spot ; fringe tawny yellow, 

 with two black spots about the middle. Hind wings ochreous,
