374 Mr. R. E. Turner on Fossorial Ilymenoptera. 



The latter is probably a syuonym o^ A.moneduloides, Pack, 

 I suspect that A. rufonodis, Rad., will prove to be a 



synouym o£ A. amatorius^ Sm. 



The genus seems to me to be most nearly related to 



Kohlia, Hand)., though diflfering in the convergence of the 



eyes and the clavate antennae. 



Ammutomus africanus, sp. n. 



5 . Nigra ; clypeo, fronte sub antennis, scapo subtus, pronoto postice 

 angustissime, mesonoto macula minuta aagulis posticis, segmento 

 dorsali primo macula transversa utrinque, segmentis 2-5 fascia 

 angusta apicali, tibiis supra tarsisque albido-flavia ; alis hyalinis, 

 venis nigris. 



Long. 9 mm. 



$ , Eyes strongly convergent towards the clypeus, at the 

 base of which they are separated by a distance equal to about 

 two-thirds of the length of the scape ; posterior ocelli nearly 

 twice as far from each other as from the eyes. Antennae 

 clavate, the four apical joints as broad as long or broader. 

 Opaque, covered with very delicate, close-lying, white pubes- 

 cence ) head almost smooth, with a well-marked frontal 

 sulcus reaching the anterior ocellus ; thorax and median 

 segment sparsely punctured ; the basal area of the median 

 segment distinctly defined, triangular, and very sparsely 

 punctured. Mesopleurae rather closely punctured, the sides 

 of the median segment almost smooth, with a few scattered 

 punctures. Abdomen shallowly and rather sparsely punc- 

 tured ; first segment narrow, nearly three times as long as 

 the apical breadth, of almost equal width throughout, not 

 constricted or inflated at the apex, about equal to the second 

 segment in length, but not more than one-third of the apical 

 breadth of the second segment. Hind tarsi veiy long and 

 slender, fully as long as the tibia and femur combined ; hind 

 tibiae with very short feeble spines ; anterior tarsi without a 

 comb. Second abscissa of the radius about equal to the first, 

 but distinctly less than half as long as the third. Both 

 recurrent nervures received by the second cubital cell, the 

 distance between them on the cubitus slightly exceeding the 

 length of the second abscissa of the radius (in one specimen 

 slightly less). Cubitus of hind wing originating a little 

 before the transverse median nervure. 



The yellow band at the apex of the second dorsal segment 

 is narrowly interrupted in the middle.

This is the first species of the genus recorded from the
