new Genera of Ichneumonidee. 375 
Scutellum convex, its top broadly rounded. Median segment 
sharply and widely depressed at the base, not areolated except 
in the middle, which is bordered by two stout keels ; ; the apex 
has a sharply “oblique slope ; on the top at the sides is a stout 
tooth. Abdomen bluntly pointed at the apex; there are 
eight segments in both sexes, the last is small; the ventral 
fold is stout and extends to the apex of the fourth segment in 
both sexes. Legs stout, the tarsi bare. 
The abdominal segments are closely but not strongly punc- 
tured, and do not angularly project at the apex laterally ; the 
sides of the median segments are bordered by stout keels; 
the head is obliquely narrowed behind the eyes; the lower 
sides of the pleure are not broadly rounded; the part of the 
mesopleure above the middle broadly and roundly projects, 
the part immediately under the wings being depressed ; 
below the raised part of the scutellum is a stout keel, 
which also extends round the apex, but is narrower there 
than on the sides; its apex has a rather steep slope; the 
front is deeply and widely depressed; the clypeus 1s more 
distinctly convex than usual. The abdomen is not much 
longer than the thorax. 
Has the coloration of Gathetus, Vacydes, and Dimetha. 
The first-named is readily known from it by the flat scutellum, 
by the much shorter, more distinctly dilated antenna, and by 
the striated abdomen. Facydes and Dimetha have “also the 
antenne shorter and more distinctly dilated, and have the 
sides of the abdominal segments angularly projecting, and 
both have the clypeus flat, while Lémetha has also the 
abdomen much longer, the postpetiole much narrower, the 
legs longer, and the scutellum not pyramidal,

Long. 15 mm. 
Antenne stout, the flagellum almost bare, the scape rufous 
beneath, thickly covered with short pale ‘hair. The inner 
orbits and the base of the mandibles are obscure yellowish ; 
the face closely punctured, more coarsely in the middle; 
thickly covered with short fuscous hair; the clypeus obliquely 
projecting, more strongly punctured and more thickly covered 
with longer fuscous hair; its apex transverse; the mandibular 
teeth are black ; the palpi thick, rufous. Front depressed, 
smooth, shining, glabrous; the vertex smooth and shining, 
bare ; the ocelli surrounded by a shallow furrow. The meso-
