206 NOVITATES ZOOLOGICAE XXIII. 1916. 



Underside white, with costal edge of forewing yellow ; fringes yellow, with 

 blackish dots. 



Tondano, N. Celebes, September — October 1899. Type in coll. Tring Mus. 



43. Gelasma hemitheoides spec. nov. 



c?, 28-31 mm. Face and palpus dirty brown, the latter narrowly whitish 

 beneath. Vertex narrowly white. Occiput, thorax and abdomen concolorons with 

 wings. Antennal pectinations long and lax. Hindtibia not very strongly dilated, 

 the hair-pencil present, but not very thick. 



Forewing olive ; costal edge ochreons, with dark dots or strigulae ; lines white ; 

 antemedian from before one-fourth costa, oblique outward, strongly curved in cell, 

 rather deeply angled inward on M, excurved at fold, somewhat incurved on SM 2 ; 

 postmedian fine and rather weak towards costa, otherwise strong, deeply lnnulate- 

 dentate, the deepest and thickest lunule at the fold ; discal mark elongate, nearly 

 obsolete ; termen with small whitish dots at vein-ends ; a fine whitish line at base 



of fringe, which is otherwise dark grey, darker proximally than distally. 



Hindwing quadrate, with abdominal margin long, tail at R 3 strong ; discal mark 

 sometimes rather stronger than on forewing ; postmedian line reproduced, 

 projecting outward at R 3 — M 1 ; termen and fringe as on forewing. 



Underside white, forewing anteriorly slightly greyish and with costal edge 

 nearly as above ; fringes nearly as above. 



Khasis : Shillong, etc. Type in coll. Tring Mus. 



Has been confused with griseoviridis Warr. Wings longer, with longer tail 

 to hindwing (shape of the Hemithea insularia group), colour less dark grey, lines 

 much more deeply lunulate-dentate. 



44. Gelasma mutatilinea spec. nov. 



S, 32 mm. Similar to thetydaria Gneu. Palpus rather longer, one-and-a-half 

 times diameter of eye, as against one-and-a-qnarter. Pectinations of antenna not 

 quite so long, ceasing earlier (little beyond middle of shaft). Face darker. Wings 

 narrower, hindwing with apex squarer, tail longer (about shape of preceding 



species). Forewing with costal edge more strongly dark-dotted, the green lines 



(bands) not quite so thick, antemedian more curved inward auteriorly, postmedian 

 receding from termen anteriorly (in thetydaria strongly approaching it), fringe 

 darker (olive-green in proximal half). Hindwing with DC less oblique outward. 



Khasis, Type in coll. Tring Mns. 



45. Thalassodes tanymelea spec. nov. 



S ?, 43-45 mm. Excessively like dorsipunctata Warr., differing as follows : 



Palpus in both sexes longer, third joint in c? almost, in ? fully as long as 

 second. Antennal pectinations in c? longer. Hindtibial process in <$ longer, 

 extending somewhat beyond middle of first tarsal joint. Forewing with post- 

 median line still weaker, appearing less dentate, through the entire suppression of 



the white dashes on the veins. Hindwing rather more weakly angled at R 3 , 



postmedian line as on forewing. 



Rook Island, July 1913, 2 <$ <$ , one being the type ; August 1913, 2 ? ¥ 

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



A pair of dorsipunctata Warr. occurred in the same locality in July.
