SO NOVITATES ZOOLOGICAE XXIII. 1916. 



and a large dark cloud (about 2 mm. in breadth) at distal margin from R 3 to 

 tornus. 



In addition, the face and palpus are blacker above, thorax more deeply 

 infuscated anteriorly, abdomen with stronger dark marks dorsally opposite the 

 proximal dark mark of hindwing and additional dark mark near anus, correlated 

 to the tornal blotch ; postmedian line a little farther from termen. 



Goodenough Island, 2500-4000 ft., April 1913 (A. S. Meek). Type in 

 coll. Tring Mus. I believe I have seen it from other localities in the Papuan 

 subregion. 



67. Prosthetopteryx eusemozona sp. nov. 



c?, 18 mm. Head and thorax light brown, darker spotted. Abdomen mostly 

 pale. Fore and middle legs dark, becoming pale at extremities of joints. 



Foreioing smooth-scaled, very pale green, inclining to olive-yellow; markings 

 red-brown, finely dark-edged ; basal patch slightly crenulate at its edge ; a costal 

 spot between this and median band ; median band very narrow, straight-edged, 

 gradually tapering posteriorly ; an elongate costal triangle from apex, its inward 

 point at R 1 , a slight pale interruption indicating the subterminal line ; a moderately 

 broad oblique-edged terminal cloud from hindmargin about to R 2 , where it ends in 

 a point ; subterminal line faintly traceable hereon ; termen with black dashes, 



"weaker posteriorly ; fringe red-brown, weakly dark chequered. Hindwing with 



slight, shallow excision in termen behind R 2 ; rather paler than forewing ; a patch 

 of specialised black scaling along R 3 -M l , recalling that of Tripteridia albimixta 

 Warr. {Nov. Zool. xiii. 131), but broader. 



Forewing beneath more greyish, paler posteriorly ; weakly marked with 

 median and subt.orminal bands, which tend to dissolve into lines and to become 

 obsolete posteriorly. Hindwing with still vaguer traces of curved transverse 

 lines. 



Mount Goliath, Central Dutch New Guinea, 5000-7000 ft., January 1911 

 (A. S. Meek). Type in coll. Tring Mus. 



Perhaps nearest infantilis Warr. {Nov. Zool. xiv. 158), which has the anterior 

 excision of hindwing very much larger, the band of forewing much less straight 

 and concise. 



Syzyx gen. nov. 



Face with projecting cone of scales. Palpus long, second joint rough-scaled 

 above and with long, forward-projecting scales beneath, third joint smooth, elongate. 

 Tongue present. Antenna in $ ciliated. Femora glabrous. Hindtibia in $ with 

 terminal spurs only. Metathorax rather strongly crested. Abdomen loosely 

 crested. Forewing shaped as in broad-winged Eapithecia; DC nearly vertical; 

 areole single, ample. Hindwing shaped nearly as in Eupithecia, in S with slight 

 excision in distal margin at tornus, a fold along abdominal margin below, as in the 

 Chesias group ; DC nearly straight ; SC 2 stalked, R 2 from slightly behind middle 

 of DC, M 1 well separate, M 2 and SM 2 wanting. 



Type of the genus : Syzyx postfalvata sp. nov. 



68. Syzyx postfulvata sp. nov. 



3, 21 mm. Head and palpus ochreous, the face with a slight tinge of olive. 

 Thorax above more mixed with olive, metathorax witli some slight dark spots ; 

 beneath pale. Fore and middle tibiae and tarsi blackish, with whitish spots at
