352 MR..W. WAHREN OB" NEW GENEEA AKD [Apr. 18, 



tooth at end of the last subcostal and median nervules ; the upper 

 half vertical ; the lower very oblique : hind wings broad, strongly 

 crenulate, with a deeper excavation between the last subcostal and 

 last median nervules opposite the cell : palpi porrect, extending 

 beyond face ; antennae of cJ pectinated ; hind tibiae of c? rather 

 swollen, with 4 spurs. 



Type, C. cluilybeata {Odontoptera), Moore. 



As the hind wings possess a distinct radial, this genus must be 

 transferred to the Greometrinae. 



ChLOKODONTOPERA iEETJGIKATA, Sp. n. 



c? . Tore wings olive-green, with very indistinct markings, which 

 consist of a rusty discal spot and 2 transverse lines, indicated by a 

 curved series of whitish spots ; the first curved at \, the second 

 sinuous, from f of the costa to | of the inner margin ; the first is 

 edged outwardly and the second internally by a very faint rusty 

 shade ; fringes dull rusty ; hiud wings the same ; head, thorax, 

 and abdomen all dull olive-green. Underside much brighter olive- 

 green, tinged \\ith rusty yellow; the 2 lines and the discal spot 

 being rust-red, and the costa for ^ from the base broadly dull 

 red ; fringes brown-black. 



Expanse of wings 23 millim. 



Hah. Naga Hills. 



Much smaller than, and different of aspect from, the typical 

 species, but structurally congeneric. 



[Eour males, ^^•hich agree perfectly, were taken by Doherty at 

 5000 to 7000 feet in the ISTaga Hills.— ZT. J. ^.] 



GELASM-i, gen. nov. 



Fore wing with tlie costa curved and short in proportion to the 

 breadth of the Ming ; apex distinct, but not aculeate ; hind margin 

 curved. Hind wings with blunt and short tooth, the hiud margin 

 on each side of it curved. Antennae of S with short pectinations, 

 which only extend to k of the length of the shaft ; hind tibiae 

 thickened, with 4 short spurs. 



Type, G. thetydaria (lodis), Guen. 



G-ELASMA CONCOLOR, sp. n. 



$ . Eore wings dull grass-green ; the costa finely dark purple, 

 minutely spotted with ochreous ; a fine dark line of the same tint 

 along the base of the fringes, interrupted by a very minute pale 

 dot at end of each vein ; a distinct and rather large black discal 

 dot ; the usual lines paler ; the first indistinct, denoted by pale dots 

 on the veins ; the second, parallel to the hind margin, is represented 

 by linear dark dots on the veins, tipped externally with white, the 

 M'hite spot on the inner margin being much larger and more con- 

 spicuous than the rest. Hind wings like fore wings ; fringes of 

 both wings concolorous. Head and thorax deep grass-green; 

 abdomen above olive-green ; antennae and fillet distinctly pale
