THELYASCETA, n. g.

in <g moderately ciliated, in 5 thickened with dense rough pro¬ 
jecting scales above on basal basal joint elongate, without pecten. 
Labial palpi very long, recurved, second joint thickened with 
appressed scales, laterally compressed, terminal joint as long as 
second, slender, acute. Maxillary palpi very short, filiform,
