bar with SO'''* about opposite the origin of 8C*, SC^"'' long- 

 stalkecl from just before end of cell, SO'"'' sepai-ating near apex ; 

 radials normal ; M' long-stalked with R*, M^ arising rather near 

 end of cell. Hind wing only about half the length of fore wing, 

 costal margin strongly concave, termen with long projecting 

 teeth at SC^ and R', otherwise sinuous rather than dentate, 

 tornus moderate ; cell about one-half, DO incurved ; C approxi- 

 mated (but not appressed) to SO to near end of cell, then 

 moderately diverging ; SC^ from close to end of cell ; R- absent ; 

 R^-M^ long-stalked, M"^ from very near end of cell. 

 Type of the genus : Sesquialtera ridicida, sp. n. 



Sesquialtera ridicula, sp. n, (PI. II. fig. 11, $ .) 



$ , 32-36 mm. Head, body, and fore wing fuscous with darker 

 irroration. Fore wing extremely weakly marked, a darker cell- 

 mark and a postmedian line indicated, the latter remote from 

 termen, strongly excurved at radials ; sometimes also a vague, 

 diffuse, oblique, somewhat curved antemedian line or shade in- 

 dicated. Hind wing variable, in the type with the basal area 

 blackish fuscous, the rest more concolorous with fore wing, but 

 traversed by ill-defined ferruginous-brown bands, in other ex- 

 amples more uniform, the base being less blackened, the ferru- 

 ginous scales largely suppressed ; a blackish discal dot, crossed or 

 closely preceded by the more or less sinuous antemedian (median) 

 line and followed by a distinct postmedian (darker brown or 

 blackish) sinuate inwards between radials and in submedian area ; 

 a brown or black terminal line. Under surface similar to upper, 

 in the type less variegated in hind wing.
