J. There is (inl\' one-thinl of an anU'iiiia left lietweeii the two sjieeimeus known 

 of this species ; \i\i^ not jicctindtcd, \n\t simply grooved as iu ordinary cJ-antennae, 

 and the compressed ventral parts are not narrowed to separate lobes. Foretibia 

 longer than in the preceding ; no mid- and hiudlegs preserved. Forewing more 

 elongate-triangular : D- of hindwing somewhat longer than D', this not twice the 

 length of 1)', lower angle of cell more acute than in mira. Tenth tergite more 

 rounded dilated, apex pointed. (Jlasper sole-shajied, narrowed to apex ; harpe with 

 a single spatnlate jirocess which bears before the end a short and rather high carina.
