TRIFID^. 399 



6. A. ophiogramma, Es^. — Expanse 1^ inch. Fore 

 wings silvery whitish-brown ; a broad, somewhat triangular 

 purple-brown blotch, occupying most part of the costa, 

 extends to below the middle of the wing and includes 

 the yellow reniform stigma ; two other purple-brown tri- 

 angular blotches are on the hind margin ; hind wings pale 

 smoky-brown. 



Antennte of the male rather stout, simple, downy in front, 

 light brown ; palpi small, horizontal, narrowly tufted, dark 

 brown, apical joint black ; head brown in front, brownish- 

 white above ; collar erect, brownish-white, broadly barred 

 near its upper margin with purple-brown ; remainder of 

 thorax pale drab or brownish-white, the shoulder-lappets 

 dotted with brown or black ; top crest small but erect and 

 divergent ; back crest small and obscure, fascicles white ; 

 abdomen pale drab dusted with brown ; on the dorsal ridge 

 are one or two almost prostrate tufts, hardly to be called 

 crests; lateral tufts spi'eading; anal tuft broad, tinged with 

 pale chestnut. Fore wings blunt, costa gently curved ; apex 

 bluntly rounded ; hind margin almost perpendicular, and 

 straight to below the middle, whence it is elbowed and more 

 oblique — even hollowed above the anal angle, which is thus 

 rendered prominent ; dorsal margin straight ; colour silvery 

 pale buff or whitish-brown, slightly clouded behind with 

 fulvous, the ordinary pattern of markings only obscurely 

 indicated ; basal line suggested by a pair of faint brown 

 curves above the median nervure ; first line very oblique, 

 white, faintly edged in the dorsal portion with black ; second 

 line just visible as a disjointed series of white curves followed 

 at some distance by a row of white dots placed between black 

 ones on the nervures ; from the base of the costa originates 

 a large purple-brown blotch, the margin of which, crossing 

 the basal line, curves down the first line to below the middle 

 of the wing, then proceeds straight to the second line and 

 follows it to the costn, thus forming a most conspicuous 

 flatly triangular blotch, the broad base of which occupies
