324 HTMENOPTEEA. 



rugose, broadly, but largely, projecting in the middle; front slightly depressed above 

 the antennae; a broad and deep furrow leading down from the ocelli, which are 

 surrounded by a narrower triangular one. Face, prosternum, metathorax, and coxae 

 covered with long white hair, the abdomen and legs with shorter hair. Metathorax with 

 a gradual rounded slope to the apex, the apex with a raised border. Petiole deeply 

 depressed in the middle at the basal fourth ; the raised central mass narrowed at the 

 base, the apex rounded ; inner furrow wide, the outer one placed below the raised 

 margin. The suturiform articulation moderately deep and wide, curved. There are no 

 depressions on any of the segments, which are shining, impunctate, and depressed at 

 the base. The abdomen is a little longer and not much wider than the thorax, and 

 becomes gradually narrowed from the third segment to the apex. The apices of the 

 four front femora, their tibiae and tarsi, the apices of the hind tibiae, and the hind tarsi, 

 are black ; the base of the tibiae and the spurs white. The cubital nervure is slightly 

 angled at the base, and the recurrent nervure received a little in front of the transverse 

 cubital one. 



The amount of black on the legs varies, and the abdominal segments are sometimes 

 streaked transversely with obscure yellow.

Antennae as long as the body, moderately stout ; densely, microscopically pilose ; the 

 joints very closely articulated; scape reddish beneath. Head shining, impunctate 

 above, the face not so shining, and obscurely and longitudinally striated ; moderately 

 depressed above the antennae, the central furrow deep ; ocelli surrounded by a furrow ; 

 a wide, not very deep, furrow down the sides of the cheeks ; tips of the mandibles 

 black ; palpi pale. Thorax shining, impunctate ; scutellum narrowed towards the 

 apex, but not sharply, the sides distinct ; metanotum with a gradual slope to the apex ; 

 a furrow along the sides of the metapleurae, originating in a deep fovea. Abdomen 

 shining, impunctate ; central area of the petiole comparatively small, the inner furrow 

 broad and with a wide outer border ; segments deeply separated, the second without 

 depressions. Cubital nervure at the base broadly curved ; the recurrent nervure received 

 a little in front of the transverse cubital one ; the second cubital cellule much shorter 

 than the third.
