8. Todolachnus n. g. 
.Allied to Lachnus Bukm., but differs from it in the following characters: 
Body long, nearly parallel on the lateral sides; the 3rd, 4th and the 
subsequent joints of the antennae with numerous roundish sensoria, the 4th, 
5th and 6th subequal in length, taken together somewhat longer than the 3rd; 
rostrum short, reaching to the 3rd coxae; wings nearly double the length of 
the body, ample, media obsolete, twice forked, stigmatic nervure straight, 
parallel to the first oblique, opening at near the apex of the stigma, stigma 
long, broad, at the apex acutely pointed ; cornicles small, wart-like, not broader 
at the base ; Cauda none, the lower genital plate rounded. 
This genus is allied also to Nippolachnits Mats., from which it may easily 
be distinguished by the presence of the twice forked media of the fore wings.
