with a short frontal sulcus. Pronotum narrower than the 

 liead, ;»s long as broad, raised along the median line into a 

 strongly elevated carina, which broadens to the anterior 

 margin ; the dor-'^al surface on each side of the carina sliglitly 

 concave. JScutellum strongly rounded at tlie apex, nearly as 

 long as broad ; dorsal surface of the median segment more 

 than half as long as the pronotum. Thorax and abdomen 

 subopaque, finely and very closely punctured; first dorsal 

 segment with a transverse groove before the raised apical 

 margin ; second dorsal segment witli five strongly raised 

 carinae, including the raised apical margin ; sixth dorsal 

 segment elongate-ovate, with a median carina, not compressed 

 laterally. 



Black ; the head ferruginous ; flagellum and logs testa- 

 ceous brown, second and sixth dorsal segments and all the 

 ventral segments daik ferruginous. 



Length 7-9 mm. 



(J. Black; the mandibles (except at the apex), a trans- 

 verse line (interrupted in the middle) on the anterior margin 

 of the pronotum, and a spot on the postscutellum (sometimes 

 almost obsolete) pale yellow. Wings hyaline, nervures 

 fuscous. 



Clypeus slightly convex, a little advanced in the middle 

 and truncate broadly at the apex ; interantennal prominence 

 not much developed, only showing as a tubercle above the 

 base of each antenna. Head and thorax closely punctured 

 and thinly clothed with long grey pubescence ; anteunje 

 longer than the thorax and median segment combined. 

 Abdomen shining, fusiform, the segments not constricted ; 

 hypopygium linguiform, rounded at the apex, with a small 

 apiciil spine. Third abscissa of the radius nearly half as 

 long again as the second ; second recurrent nervure received 

 at about one-quarter from the base o£ the third cubital cell. 



Length 10-12 mm.

The pronotum of the female is very different to other 

 species of the genus, in which a longitudinal sulcus is always 

 piesent and no carina; but otherwise there is no remarkable 

 difference. The sexes are not marked as taken coujded, but 

 I have no doubt of the association. The female is the type.
