segment rounded, shining, very minutely punctured. Abdomen 

 flattened, fusiform, shining ; the dorsal segments very narrowly 

 depressed at the apex. Hypopygium narrowly linguiform, with- 

 out an apical spine. Second abscissa of the radius a little longer 

 than the third ; first recurrent nervure received at about two- 

 thirds from the base of the second cubital cell, second at about 

 one-quarter from the base of the third cubital cell. 



$ . Head smooth and shining, much broader anteriorly than 

 long, narrowed posteriorly, slightly convex ; thorax much 

 narrower than the head ; the pronotum a little broader anteriorly 

 than long, slightly narrowed posteriorly, with a longitudinal de- 

 pression on each side reaching from near the anterior angles to 

 more than halfway to the posterior margin ; scutellum narrow ; 

 dorsal surface of the median segment a little longer than the 

 scutellum, sparsely punctured. First dorsal segment broadly 

 depressed at the apex, the raised basal portion widely emarginate 

 posteriorly ; second dorsal segment with two strong transverse 

 carinee near the base, the apical margin also raised ; third and 

 fourth segments narrowly depressed on the apical margin. 

 Pygidium narrow, the sides almost parallel.

Allied to A. vicarius described above, but may easily be dis- 

 tinguished by the black legs of the male and the lateral depres- 

 sions on the pronotum of the female.

Long., d 9-10 mm. ; $ 4-5 mm. 



6 . Clypeus produced and narrowly truncate at the apex ; 

 interantennal prominence very feebly developed ;' antennae 

 scarcely longer than the thorax and median segment combined, 

 tapering slightly towards the apex ; head and thorax finely and 

 very closely punctured ; scutellum strongly convex, subcarinate 

 longitudinally in the middle ; median segment short, much 

 broader than long. Abdomen flattened, shining and almost 

 smooth, the two apical segments rather coarsely punctured. 

 Hypopygium broadly rounded, as broad at the base as long, with 

 a short apical spine. Second abscissa of the radius longer than 

 the third ; first recurrent nervure received at two-thirds from
