Lepidoptera. 79 



Type. — (J Mus. Br. 



Ilab. — Christmas Island ; Jan., 1898; unique. (C.W.Andrews.) 



A single specimen, adding to the somewhat curious tropical 



distribution of this conspicuous form, allied species occurring on 



the "West coast of Africa, Malaysia, Queensland, and extending 



northwards to Shanghai. 



C^NOGNOSIS, Wlsm., gen. nov. 



{icaivo^ = ' new ' ; <yuwat9 = ' knowledge.') 



Type : Ccenot/fiosis mcisa, Wlsm, 



Antennoe (9) simple. Palpi porrect, median joint clothed with 

 loose hair-scales beneath; terminal joint nearly half the length of 

 the median, slightly drooping, smooth. Head rather rough above. 

 Thorax smooth. Fore wings narrow at the base, slightly widening 

 outward, costa moderately straight, apex obtusely falcate, termea 

 deeply sinuate, not oblique, tornus rounded: neuration, 12 veins — 

 2 from scarcely beyond middle of cell ; 3 fi'om before angle of cell, 

 much recurved, approximating to 4 on termen ; 4 and 5 separate, 

 4 recurved, 5 to sub-apical sinus ; 6 to lower extremity of the 

 falcate apex; 7 to above apex, 8 and 9 out of 7 ; 10 nearer to 7 

 than to 11 ; II from outer third of cell. Hind wings as broad as 

 the fore wings, scarcely sinuate below the rounded apex : neuration, 

 8 veins — 3 and 4 connate; 5 parallel to 4 ; 6 and 7 stalked. 

 Abdomen normal. Legs smooth ; a slight projecting tuft of scales 

 at the end of the hind tibiae. 



Apparently allied to the IS^ew Zealand genus Epalxiphora, Meyr., 

 which is also represented in New South Wales. 



8. Csenognosis incisa, Wlsm., sp.n. 



Antennte pale brownish. Palpi white, a brownish streak on the 

 outer side of the median joint reaching to half its length, terminal 

 joint tinged with brownish. Head dark rust-brown. Thorax 

 white, with a brownish tinge. Fore wings sericeous white, costa 

 narrowly tinged with rust-brown, through which run short oblique 

 white streaklets commencing before the middle and continuing 

 nearly to the apex ; apex obtusely caudate, rich ferruginous, 

 a silvery streak running through the lower half of the 

 ferruginous patch, joined at its base by a similar slender streak 

 from the costa and at its apex by another curving around the base 

 of the apical cilia ; this patch is preceded by a dark fuscous 

 quadrate spot a little beyond the upper angle of the cell with 

 smaller patches of fuscous scales on either side of it ; along the 

 middle of the termen are three or four patches of similar fuscous 

 scales between the veins, and a few, less noticeable, are distributed
