HYMENOPTERA. 33 



tubercles and two ovate spots on the scutellum yellow ; the 

 superior wings have a dark fuscous cloud on their anterior mar- 

 gin, extending from base to apex, the width of the marginal and 

 second submarginal cells, a little palest towards the base of the 

 wings j legs ferruginous, anterior pair darkest ; the anterior tibiae 

 at their apex furnished exteriorly with a stout bent tOv>th rather 

 more than one-third the length of the basal joint of the tarsi ; 

 the tarsi densely ciliated; the intermediate and posterior legs 

 have a silvery-white pubescence, most dense on the tarsi and on 

 the posterior femora and tibiae within. Abdomen, the apical 

 margin of the basal segment has a broad yellow band, dilated 

 laterally ; a similar band, continued beneath, occupies the third 

 segment a little before its apical margin ; beneath, the second 

 segment is produced at its base into a conical tubercle.

 six-jointed. Thorax ovate, superior wings having one marginal 

 cell acuminate at its apex ; submarginal cells two, the first twice

Male. Length 4^ lines. Black, ocelli large and prominent, 

 the face deeply canaliculate, smooth and shining ; the canalicu- 

 lation occupying the whole of the face above the insertion of the 

 antennae and extending on each side of the clypeus nearly to its 

 anterior margin ; a raised yellow line traverses the inner orbits 

 of the eyes ; the clypeus yellow, angular above ; the labrum, 

 mandibles and antennae ferruginous, the scape broadly dilated, 

 yellow in front. Thorax, the prothorax slightly elongated, the 

 collar narrowly yellow, the disk strongly punctured ; the meta- 

 thorax rounded and covered with griseous pubescence ; the te-
