HYMBNOPTEROUS FAMILY STEPHANID.E. 789 



Black ; mandibles except apex, basal half of antennse, a streak 

 on temples along eyes, the tegulse, tibise and tai-si yellow. Wings 

 colourless hyaline. 



Length 10-11 mm. 



Habitat : Johann Albrechtshbhe, N. Cameroons. L. Conradt ; 

 1895-96. 



Differs from F. hrevicollis Enderl. in the formation of the pro- 

 pleura?, reticulate transrugose face, longer and smoother pronotum, 

 and shorter petiole.

Stephanus hrevicollis Enderl. (1), p. 201, 5 . Fcenatopus h. 

 (2), p. 474. 



5 . Head densely granulate rugose ; vertex transrugose ; 

 occi]3ut densely punctate rugose. Postei'ior margin of head 

 shai'ply bordered. Second flagellar joint a little longer than 

 first ; third and fourth as long as scape and about as long as first 

 and second together. Pronotum short, densely punctate rugose ; 

 mesonotum and scutellum densely punctate, latter without any 

 central smooth space ; metanotum finely transrugose. Propleurse 

 separated from prothorax by a distinct acute-angled sulcus, 

 produced into free-standing edges, which, seen laterally, appear 

 like two sharp points. Mesopleurae above smooth and shining, 

 lower half punctate ; metapleurae and median segment separated 

 only by a smoother streak, and both closely punctate. Petiole 

 extremely finely trans-striate, as long as rest of abdomen. 

 Terebra rather shorter than body ; the spicula and sheaths, 

 except black apex, yellow-brown. Hind coxse finely trans- 

 striate. 



Black ; mandibles except apex, three basal antennal joints, 

 tegulee, anterior tibiae and all tarsi yellow- brown. Wings hyaline. 



Length 7-10 mm. 



Habitat: Bismarcksburg, Togo. L. Conradt ; 1893. 



This species appears to differ from all others in the peculiar 

 formation of the propleurse. From F. schlettereri Enderl. it further 

 differs in the shorter prothorax and coarser sculpture of pro- and 

 meso-notum.

5 . Frons very densely arcuately longitudinally rugose ; vertex 

 with three or four coarse ridges; occiput densely irregularly 

 rugose, with subobsolete central channel. Temples subrugose 

 near the eyes. Posterior margin of head slightly bordered. Basal 

 flagellar joints normal, third slightly shorter than fourth and as 

 long as scape. Neck obliquely rugose, remainder diffusely
