46 Mr. R. E. Turner on Fossorial Hymenoptera. 



strife posteriorly ; front rather less coarsely punctured, the 

 area between the frontal carina? with a tendency to oblique 

 striation. Second joint of the flagellum twice as long as the 

 third, the latter less than three times as long as its apical 

 breadth. Eyes strongly convergent towards the vertex, 

 where they are separated by a distance equal to about three- 

 quarters of the length of the second joint of the flagellurn. 

 Pronotum nearly as broad in the middle as long, produced 

 posteriorly into a strong tubercle, transversely stiiated in 

 the middle, smooth at the base and apex, not punctured, 

 propleura? smooth. Mesonotum sparsely, scutellum very 

 sparsely, mesopleura? rather more closely punctured, the 

 scutellum with the usual transverse crcnulated groove at the 

 base. Median segment transversely striated, the second 

 carina nearly twice as far from the median carina as from the 

 third at the base, the apical area of the dorsal surface not well 

 defined, the teeth at the apical angles strong and subtri angular. 

 Abdomen smooth and shining, second tergite as long as its 

 greatest breadth. Fourth tarsal joint half as long as the fifth 

 and fully as long as the third in the middle ; hind tibise very 

 sparsely punctured. Fourth abscissa of the radius about half 

 as long as the second transverse cubital nervure, first trans- 

 verse cubital nervure indicated, but subobsolete. 



$ . Clypeus broadly rounded at the apex, without teeth, 

 and rather densely clothed with grey hairs. Head coarsely 

 punctured, the frontal carina? produced posteriorly and meeting 

 behind the anterior ocellus, the space between them with 

 distinct oblique stria? and a median longitudinal carina. 

 Second joint of flagellurn more than half as long again as the 

 third ; eyes less strongly convergent towards the vertex than 

 in the female, separated by a distance scarcely less than the 

 length of the second joint of the flagellurn. Thorax rather 

 more closely punctured than in the female, the pronotum with 

 distinct punctures. Abdomen closely and strongly punctured ; 

 the third tergite sparsely clothed with cinereous hairs.

Somewhat resembles A. craivshayi, Turn., but in that 

 species ( ? ) the mandibles are red, the wings almost hyaline, 

 the head not produced posteriorly and scarcely narrowed 

 behind the eyes ; the frontal carina? meet behind the anterior 

 ocellus, and the front tarsal joint is shorter, in addition to 

 other differences. The female is the type.
