( n23 ) 



The insect resembles A. eapreolnrin Schifl'. The ? ?, as a rule, are jiaU'r and 

 more clearly marked than the (^c?. 



The form above described is the commonest, but the species varies in two 

 directions; one being cinereous-fuscous with all the markings becoming obsolete, 

 the other with all the markings very distinct, the central fascia black, and the ground- 

 colour on each side unspeekled clear whitish or whitish ochreous ; this form may be 

 known as ab. separata.

Fcn-evmigs: Jiale ochreous, striated and suffused wilh olive-brown; tiie lines 

 dark brown; tirst at one-third, double, angled in cell, the two arms rising from 

 brown costal spots; median line from a similar spot; outer line at two-thirds, also 

 from a costal spot, bluntly angled beyond cell, then oblique, irregularly crenulate ; 

 followed immediately by a finer line which is edged between veins 2 and 6 by a 

 patch of purple-brown and grey scales, emitting on each side of vein 5 a dark streak 

 to hindmargin, above which there is a pale triangular apical blotch; submarginal 

 line indistinct, close to margin; marginal dark spots between the veins; fringe 

 ochreous and brown ; cell-spot brown, indistinct. 



Hindwinr/s : similar ; the basal and marginal areas browner than the central. 



Underside : basal two-thirds pale ofhreous, with dark speckles, especially along 

 eosta, and with distinct brown cell-sjiots; marginal third occupied by a fuscous 

 brown border, paler at apex of forewings. Head, thorax, and abdomen ochreous, 

 varied with brown and black.

 80. Catascia confusata sp. nov. 



Forewings: ochreous, with a pinkish yellow tinge, covered with (ilive-fuscous 

 striae, rendering the lines and markings confused ; tirst at one-fourth, diffuse, bent 

 below subcostal vein, then vertical and waved, preceded by a thick dark shade; outer 

 line from two-thirds of costa, oblique outward to vein 5, then inward, ilentate- 

 lunulate, to middle of inner margin, followed by a similar thick dark shade ; 

 submarginal line lunulate-dentate, very obscure, preceded by darker scaling in the 

 lunules at costa, lieyond cell, and in submedian interval, the space between these 

 darker patches being pinkish and less speckled; discocellular marked with black 

 scales ; marginal spots black, connected by a fine line ; fringe pinkish, mottled 

 with darker. 



Hindwings: paler except round anal angle and along hindmargin, where the 

 olive speckles are thicker; traces of the commencement of postmedian and sub- 

 marginal lines on inner margin ; cell-spot black ; fringe as in forewings. 



Underside ochreous, tinged along hindmargin with pinkish yellow, and thickly 

 mottled all over with grey; cell-spots dark. Thorax, abdomen, and vertex yellowish
