Phygadeuon (Stibeutes) yuasai n. sp. 
2. Black, polished and shining; the antenne at base, palpi, and all of 
the legs straw-yellow; second dorsal segment somewhat pale at base, 
medially. Wings stained slightly, the veins and stigma pallid brownish. 
Length 3 mm. 
Head large, one and one fourth times as wide as the thorax from tegula 
to tegula. Seen from above, its posterior margin is deeply concave, its 
length measured along the median line equal to one half of its extreme 
width (measured between the outer limits of the eyes), and its greatest 
length, on either side, three fifths of the width. Temples broad, margined 
posteriorly; vertex polished and impunctate; front polished and with only 
a trace of minute shallow punctures; face convex, separated from the 
small convex clypeus, the latter with rounded anterior margin; eyes re- 
mote from the mandibles, the cheeks polished and impunctate. Antenne 
rather short and somewhat thickened, composed of 20 segments, the scape 
stout, the 3d segment a very little shorter than the fourth (about one 
eighth), the latter twice as long as wide at apex, the more apical segments 
as wide as long or wider, except’ the ultimate. ; 
_Mesonotum noticeably flat, polished and impunctate; parapsidal grooves 
indicated at antero-lateral margin; scutellum delimited, a carina on each 
side at base, convex, impunctate and shining; propleure and mesopleure 
polished and shining, impunctate, the latter with a large deep pit at some 
distance below the base of the hind wing; sternauli strongly impressed, 
becoming subobsolete at posterior margin of the segment, somewhat crenu- 
late anteriorly; mesosternum polished but with sparse shallow punctula- 
tion, and with a deep and broad crenulate median longitudinal furrow; 
- prepectus poorly defined laterally, but the prepectal carina prominent ven- 
trally; metapleura smooth, impunctate, polished. Propodeum obliquely 
truncat'e posteriorly, its angles obtusely elongate, forming a fossa, im- 
punctate smooth and shining; the areola semicircular, the basal area trans- 
verse, the carinz well marked, the surfaces of the area shining and smooth. 
Posterior coxe large, the femora and tibie stout, the latter somewhat’ con- 
stricted at base. Wings as long as the distance from the tegule to the 
apex of the petiole (nearly 1%4 mm.) ; wing apex obtuse, the stigma large; 
apex of the marginal cell about midway between apex of the stigma and 
tip of the wing, distant from the stigma by less than the length of the 
latter, however; submedian cell (Cu-++Cu,) ending slightly beyond the 
median (M) ; second discoidal cell (M;) small and triangular; the first 
recurrent vein (M,,,) is absent, and the disco-cubital cell (1st R, + R+M.,) 
is thereby united with the 3d discoidal cell (1st M.) and this in turn by 
the absence of the second recurrent and subdiscoidal veins (M. and m) 
is united with the cells around the wing margin. In the hind wings there
