182 THE ENTOMOLOGIST. 



Wings yellowish hyaline, the apices blackish ; the areolet narrowed 

 at the top ; the first cubital nervure slightly, the second distinctly, 

 roundly curved, the two almost uniting at the top ; the recurrent ner- 

 vure is received almost in the middle. The basal half of the petiole 

 greatly narrowed, yellowish ; the apical with two stout keels down the 

 middle, and coarsely punctured ; the other segments coarsely rugosely 

 punctured, striolated at the base down the centre ; all the segments 

 separated by a deep moderately wide depression ; the ventral surface 

 whitish.

Antennas black ; the tenth to fifteenth joints white, stout ; the scape 

 yellow beneath, and covered with short white hair. Head black ; the 

 face, except for a conical mark in the middle under the antennae, the 

 clypeus, labrum, the inner orbits above, and the outer more broadly 

 below, and the palpi, yellow ; the clypeus is edged with black at the 

 sides and apex ; the mandibles are entirely black. The face is closely, 

 the clypeus more coarsely and not so closely punctured. Vertex 

 strongly punctured, and with a few oblique striae below the ocelli ; the 

 front depressed, at the sides very smooth and shining. Thorax black ; 

 a broad line on either side of the base above, the tegulfe, scutellum, 

 except at the base, the post-scutellum, the scutellar keels, the apex of 

 the median segment at the base and sides, the base more narrowly 

 than the sides, where the yellow is dilated broadly outwardly, and a 

 somewhat oval mark immediately under the hind wings, yellow. Meso- 

 notum closely and strongly punctured, thickly covered with short white 

 hair ; its middle lobe is distinctly raised at the base ; the scutellum 

 shining and thickly covered with long white hair, and sparsely punc- 

 tured ; the punctures are large, round, and shallow ; the post-scutellum 

 is almost impunctate ; its base is deeply bifoveate ; the depression at 

 the sides is not striated, and is covered with long white hair. The 

 median segment, at the base behind the transverse keel, is closely 

 punctured ; the punctuation is stronger towards the apex, in the 

 middle of which is a stout short semicircular keel ; in front of the keel 

 the segment is coarsely punctured, rugosely so at the apex, which has 

 a slight oblique slope ; its sides and top are bordered by a stout keel ; 

 the black mark in the middle is rounded at the base, transverse at the 

 apex, and twice longer than broad. Pro- and meso-pleurte closely 

 punctured ; the lower part of the former with some stout longitudinal 

 keels at the apex ; the metapleuras more strongly punctured ; the punc- 

 tures run into reticulations, and are stronger on the lower side ; over 

 the hinder coxas is a large yellow mark, twice longer than broad, and 

 rounded and narrowed at the top. Wings hyaline, the apex smoky ; 

 the stigma and nervures black ; the areolet is a little longer than wide, 

 slightly narrower at the top than at the bottom ; the recurrent nervure 

 is received shortly beyond the middle ; the second transverse cubital
