Bembex odontopi/ga, sp. n. 



J . Niger ; mandibulis, apice excepto, labro, clypeo macula basali 

 nigra utrinque, scapo subtus, orbitis, femoribus, tibiisque subtus, 

 tarsisque flavis ; flagello subtus obscure brunneo ; segmentis 

 dorsalibus 2-4 fascia angusta late iutorrupta, quinto sextoque 

 fascia continua, septimo macula obliqua utriuque, segmentisque 

 ventralibus 2-5 fascia angusta continua apicali bruuneo-flavis ; 

 segmentis dorsalibus obscure Cceruleo-micantibus ; segmento 

 septimo dorsali apice fusco-ferrugineo ; alls hyalinis, venis fuscis. 



Long. 19 mm. 



($ . Clypeus with a carina from tlie base to beyond the 

 middle, deflexed from tlie end of the carina to the apex, not 

 very strongly convex ; the carina between the antennae very 

 distinct. Four apical antennal joints distinctly hollowed 

 beneath, stout, the apical joint blunt at the apex, a little 

 longer than the penultimate. Head, thorax, and median 

 segment clotlied with long wliitish pubescence, that on tlie 

 niesonotiim shorter and brownish. Fore tarsi normal, the 

 basal joint with seven spines ; fore and intermediate femora 

 not serrate. Median segment with a very feeble longitudinal 

 groove. Seventh dorsal segment with a short spine on each 

 side near the base, tlie apex rather broadly truncate, not 

 undulating at tlie sides. Ventral segments unarmed. Wings 

 about two and a half times as long as the breadth of the 

 thorax; median cell of the hind wing emitting two veins 

 from the apex. The eyes are distinctly divergent towards 

 tlie clypeus.

This belongs to the iiV/en/ctia group, and apart from colour- 

 differences may be distinguished from nwbii by the absence 

 of a strong tooth at the apex of the intermediate femora ; from 

 hidentata by the more distinct carina of the cl3'peus, by the 

 colour of the pubescence, and by the broader apex and less 

 developed teeth of the seventh dorsal segment. B. scotli, 

 Turn., the only remaining African species of the group, may 

 be at once distinguished from this by the much finer and 

 sparser puncturation of the thorax and median segment. In 

 colour odontopyya resembles compedita, Turn., which is allied 

 io J nscipennis,
