Apex with a rather distinct, chitinous tip. Ventral surface of abdominal segments thickly clothed with rather long, slender hairs usually extending laterally. Apical three fourths of the in- ner margin of the hind paddle distinctly serrate, each tooth bearing a short, colorless spine. Terminal appendages consisting of two pairs of conic processes, the outer ones end- ing in a colorless spine, con- cave and inclosing the bases of the inner, shorter, more strongly curved ones. At the extreme base of these posterior processes there are a pair of chitinous, irregularly curved, blunt hooks. Larva. Head, somewhat elongate, subconic. Basal segment of antennae long, deeply notched at base and tipped with four nearly equal, tapering processes and another just about one half their length. Just behind the antennae are 10 long, light brown- ish filaments, five on each side, th^ filaments of the third meta- Kg. 102 Ventral hook of. trivittati.
