496 List of Species belonging io the Family Pyralidae 



ochraceous-orange ; anal tuft of black hairs mixed with white, or as in 

 one specimen, black, tipped with ochraceous-orange. Fore wing with 

 the costa broadly (as far as upper median) bordered with antimony- 

 yellow (xv) ; basal third of cell and half the distance below lower 

 median covered with baryta-yellow (iv) scales, edged outwardly by some 

 fuscous scaling : a rounded similar mark half-way of cell, also edged, 

 except along upper median, by fuscous shading ; another wedge-shaped 

 similar mark at end of cell, here and there edged by fuscous scales, 

 straight on inner side and incurved outwardly, following discocellulars } 

 forming a well-defined spot at lower angle ; a round similar mark at 

 middle of inner margin between veins 16 and 2, also finely edged by 

 fuscous scaling ; postmedial line formed by a series of intra-nervular 

 ill-defined maculae, consisting of vinaceous-buff scaling, running parallel 

 to inner margin and situated rather close to it (in some specimens the 

 line is slightly incurved at vein 2) ; a terminal faint ochraceous-orange 

 line, with fuscous scaling on the veins, narrow and long before middle 

 and broader but shorter towards the apex; cilia marguerite-yellow (xxx) 

 with slightly darker line across middle. 



Hind wing with a faint discocellular mark of fuscous scaling before 

 and beyond discocellulars ; postmedial series of maculae as in fore wing 

 but even closer to outermargin and slightly incurved at veins 2 and 6 

 and getting narrower towards anal angle ;. terminal line, spots and cilia 

 as in fore wing. Underside pure white, except where markings of 

 upperside shine through it. 



? like $ , but larger and with the wings a little broader. Exp. : 

 $ type, 34 mm., ? type, 38 mm. ; other specimens, $ , 30 — 35 mm., 

 ? , 32—38 mm. 



Habitat. — £ and ? types from Central Ceram, Manusela, 6,000 feet, 

 October-December, 1919, seven other specimens from same locality ; 

 also a ? from Ninay Valley, Central Arfak Mountains (Dutch New 

 Guinea), 3,500 feet, November, 1908 to January, 1909, and one $ from 

 Island of Mioswar, Geelvink Bay (North New Guinea), September, 1909, 

 all collected by C. and F. Pratt. 



I have much pleasure in naming this species after the collectors who 

 have sacrificed so much to advance our entomological knowledge of 

 tropical regions. 



50. Margaronia brevimarginata sp. nov. 



This species mostly resembles in appearance and size M. laceritalis 

 Kenr., but is at once distinguished from it by the male having a tuft
