49. Thalassodes albifusa sp. nov. 



Forewinr/s : dark green, with two oblique diffuse broad greyish white fasciae; one 

 from middle of inner margin to upper edge of cell, and embracing the black cell-spot; 

 the other submarginal, extending to the lower radial ; fringe green ; costa yellowish. 



Hindwings : similar, the base whitish. 



P'ace, palpi, vertex, and thorax green ; front of vertex and shaft of antennae 

 white. Abdomen whitish, tinged above with green ; basal segments blackish green. 

 Forewings pale whitish green. 



Expanse of wings : 36 mm. 



One S from Fergusson Island, November. 



Subfamily STERRHINAE. 



oO. Antitrygodes parvimacula sp. now 



Forewings: stone-colom-, tinged with pink and thickly dusted with grey specks; 

 the costa finely ochreous ; a small green blotch near base below the median, and a 

 green spot above it ; first line obsolete ; two olilong irregularly oval green blotches, 

 one on either side of the discocellular, a smaller round one between the first and 

 second medians, and an oblong vertical one, sometimes divided into two, below the 

 median ; a cm"ved cloudy brownish shade just beyond ; a dull brown submarginal line, 

 outwardly curved to near the anal angle, followed by three green subapical lunules ; 

 a dark brown crenulate marginal line ; cilia concolorous. 



Hindtvings : like forewings, but without the green basal blotch. 



Thorax and abdomen concolorous with wings, the latter with green dorsal spots; 

 upper half of face and collar ferruginous ; lower half of face and vertex white. Under, 

 side pale ochreous, tinged with reddish ; both wings with a curved dark brownish red 

 submarginal band. 



Expanse of wings : 38 mm. 



One ? from Fergusson Island, December; one c?, two $5, from Kiriwini, 

 Trobriand Islands, March, April, and May. In two of the examples from Kiriwini 

 the green markings have become bright ferruginous. 



The hindmargins of the wings are only faintly crenulate, as in cwiieilinea Wlk., 

 not deeply excised, as in diviaaria Wlk. and ccgraia Feld.: from which species it may 

 be likewise at once distinguished by the smaller green spots with rounded margins. 



Ptochophyle gen. nov. 



Foretvin^s : short and broad; costa straight; apex blunt, square; hindmargin 

 olilique only above anal angle, bowed in the middle. 



Hiadwiiigs : with hindmargin faintly crenulate and with a slight projection 

 at vein 4 ; the anal angle prominent. 



Antennae of c? strongly pectinate ; palpi very short ; hind tibiae with four spurs. 



Neuration: forewings, cell not half the length of wing; discocellular vertical, 

 almost obsolete; first median at two-thirds, second before the end of cell; lower 

 radial from centre of discocellular, ujiper from top end of cell ; last four subcostals 

 stalked, the first anastomosing with them to form a single areole; the first from 

 one-third of cell, the stalk of the other four at two-thirds. Hindwings with last two 

 medians and two subcostals from the ends of cell. 



Type: Plocliophglc nolata sp. nov. 



To this genus also belongs volutaria Swiuh. = tristictda Swinh.
