patch on it, broader. In the hindwiug veins 3, 4 are on a longer stalk, and 5 is 

 stalked with them. 



3 (J (J from Tambora. 



The two species of Ariola above described belong to a different section of the 

 genus from coelisiqna Wlk., the S of which possesses a small gland in the anal 

 angle of hindwing. 



lo6. Tathothripa abbreviata spec. nov. 



Forewing : differs from T. continua Wlk. $ {= de/fexu ^Vlk. ? ) in the white 

 area of the inner margin being cut short jnst beyond the indentation, which in this 

 species is just beyond and not before middle of wing, almost the anal third being 

 dark ; the dark costal portion of wing is obscurer, the cross-lines not being followed 

 and emphasised by paler scaling ; both wings are darker, deeper fnscons, l)oth above 

 and below ; and the abdomen is blackish grey. 



1 S, the same size as continua, from the Upper Setekwa River, Snow Mts., 

 Dutch New Guinea, 2UU0— 3000 ft., September 1910 (A. S. Meek). 



The species is remarkable on account of the exaggerated length of the abdomen. 



107. Tathothripa nigricristata spec. nov. and ab. inversa ab. nov. 



Forewing : with the white inner-marginal area, as in abbreoiata Warr., 

 interrupted beyond the indentation, which, as in continua, is not beyond the middle 

 of wing, but the curved u[)per edges of the two patclies towards anal angle remain 

 grey, and the dark cross-lines are very clearly followed by pale grey spaces ; the 

 hindwiug is black with pale fringe ; the white tuft on metatborax is tipped with 

 black scales ; the abdomen, which in this form is not particularly elongate, is dull 

 blackish with yellowish anal tuft ; in all tlie specimens of continua Wlk. that I 

 have seen, those with the whole inner margiu white are SS, and those with the 

 curved basal portion only white are 2 ? ; iu one of three specimens of tiie present 

 species — ab. inversa ab. nov. — this distinction does not hold good, as, though an 

 undoubted S, it shows only the white basal area of the ?. 



All three examples are from the Ninay Valley, Central Arfak Mts., Dutch New 

 Guinea. 



108. Tympanistes alternata spec. nov. 



Forewing : pale greyish ochreous with a greenish tinge ; the lines purplish 

 grey, wavy, double ; the arms far apart ; inner line oblicpie outwards to median 

 vein, then inwards ; the space between them filled in with olive brown tinged with 

 reddish ; a reddish blotch at base of inner margin, with a black dot above on 

 median vein ; outer line excurved from subcostal vein to vein 2, the space between 

 the arms tilled in with olive brown or reddish ; subterminal line very strongly 

 waved, projecting outwards between veins (J, 7 and 3, 4, also followed by a less 

 distinct grey arm ; terminal spots round and black ; fringe pale ochreous ; the 

 median area between the two fasciae is generally filled up with reddish fuscous 

 below submedian fold. 



Hindwing : deep briclc-red, paler along costa ; fringe red. 



The ? is much paler in both wings. 



Underside of cT dull red, of the ? more ochreous red.
