New Geometridae from Central Ceram 289 



Central Ceram : Manusela, 6,000 feet, October to December, 1919. 



Although the palpus is not quite so long as in typical Gonanticlea 

 and the termen of the fore wing not bent in the middle, I think this 

 species has more in common with Gonanticlea than with Anticlea (type 

 derivata Schiff.). 



18. Xanthorhoe callisthenes sp. nov. 

 $ . 34 — 37 mm. 



Frontal cone well developed. Palpus rather long (almost 2), heavily 

 scaled. Antennal pectination long, ceasing after about the thirty- 

 second joint. Head and body pale-grey tinged with fleshy-ochreous, 

 above with rufous irroration, beneath pale, with the irroration fuscous. 

 Abdomen above with posterior edges of segments pale, preceded by ill- 

 defined dark marks. 



Fore wing whitish-grey, slightly glossy, with varying suffusions, 

 throughout with more or less strong rufous irroration ; basal patch 

 narrowing to hindmargin, predominantly red, bounded by a lunulate 

 whitish line ; succeeding area reddish in proximal half, more ochreous 

 in distal ; median band broad, edged by fine whitish lines, which are 

 indented on the veins ; anterior half of the band considerably broader 

 than posterior, central part generally pale (containing the somewhat 

 elongate black cellmark), each margin containing three blackish lines 

 (in places connected by dark suffusion), the first of the postmedian 

 series very strongly oblique inwards anteriorly, nearly meeting the last 

 antemedian at costa ; the commencement of a zigzag red-brown line at 

 costa beyond median band ; subterminal white, interrupted, partly 

 defined by greyish cloudings ; a paler patch proximally to it, between 

 SC 5 and E 2 and some pale dots on most of the veins ; a small oblique 

 whitish apical dash ; terminal line moderate, cut by pale dots at the 

 veins and midway between ; fringe with dark spots opposite the veins. 

 Hind wing less rufous, except the abdominal margin, tornus and fringe; 

 markings not strong, not reaching costa, consisting of a pair of grey 

 lines about middle, three lunulate-dentate lines enclosing two paler ones 

 (representing the " rivulet" band of the Larentiinae) and a few white 

 subterminal dots. 



Both wings beneath strongly rufous-shaded, with black cellmark ; 

 the principal lines beyond represented in dark-grey, the distal boundary 

 of median band (indistinctly) in whitish, the subterminal by whitish 

 dots.
