MOTES ON AFRICAN CHALCIDOIDEA^ — V. 127 



of the median tooth are one long and one short bristle ; above the clypeal edge the 

 face is broadly bare ; there are one or two bristles below the toruli, and none between ; 

 while on each side of the face are 40-50 similar minute irregularly-disposed bristles. 



Antenna : length, '75 mm. ; scape (7 : 2), with subparallel sides, constricted near 

 the base ; rather bare, and with minute bristles of which two, very short and 

 appressed, are ventral at one-third and two-thirds respectively ; pedicel (5 : 3) 

 barely one-half of the scape ; first ring joint about half as long as the second. The 

 joints of the funicle are subequal, but the first is one-fifth less, and the fourth one- 

 eighth longer than the others ; the first segment of the club equals the last funicular 

 in length, and the three segments are in the ratio 5:4:5; the third segment shows 

 a minute apical subdivision — probably a sense organ — which bears only bristles. 

 The breadth of funicle and club is uniform, the joints being approximately as long as 

 broad, except the first funicular, which is a little narrower. The first funicular bears 

 four sensoria, and the second six, as does also the last segment of the club ; the other 

 joints bear eight to twelve. 



Mouth-parts : mandibles broad, triangular, with inwardly curved apex ; about 

 ten bristles on the apical outer half. Inner edge with two teeth, the distal angular, 

 the more proximal rounded. Maxillary palpus very short, single- jointed, with only 

 two terminal clear minute spines. Labial palpi relatively large, two-jointed, in the 

 proportion 11:7; second joint about twice as long as the maxillary palpus. The 

 first has one external, and the second two apical spinose bristles. There are apparently 

 no cell-like structures on the lingua, whose distal edge is merely frayed. 



Thorax : prothorax smooth, except on the overlaps (below the spiracle) which are 

 reticulate. Spiracles projecting, with some minute bristles, just behind on the 

 inside, and many more in front in a broad antero-medianly interrupted band ; no 

 posterior row of longer bristles. The narrow sternite smooth, and the episternite 

 raised reticulate. Mid lobe of mesonotum smooth and bare, save for two or three 

 short bristles inside the furrows near the suture. Lateral lobes and axillae with two 

 or three short bristles, smooth, except towards the lower edge of the axillae, which is 

 faintly reticulate. Scutellum oblong, nearly quadrate, with concave sides and about 

 eighteen minute bristles (9:9); mesophragma deeply bifid apically, exactly the 

 length of the propodeon. The large tegulae, the distinctly separated prepectus, and 

 the sternum anteriorly, are coarsely reticulate and slightly raised. The remainder 

 of the sternum and the episternal sclerite smooth. Metathorax : both the post- 

 scutellum and the side areas are raised reticulate. 



Propodeon smooth, ^\^th traces of raised pattern outside and below the spiracle, 

 where are also two to three short bristles. The propodeon bears also postero-laterals 

 patches of about a dozen bristles each. 



Wings: Fore wings twice as long as broad ; length, 1*55 mm. ; breadth, '72 mm. 

 Submarginal : marginal : radius : post-marginal, as 4 : 1 : 1 : 2. The apex of the 

 post-marginal is hyaline, so that the vein appears (unless carefully examined) to be 

 shorter than it is ; the apparent ratio with the marginal being about 5 : 3, The 

 basal half of submarginal cell and the wing base to below the uprise of the vein are 

 bare. Wing ciliation regular, no hairless lines. In all the specimens examined the 

 submarginal vein bears five bristles on the basal two-thirds, and two more (after a 

 distinct gap) before the pair of pustules at the uprise. There are about 24 bristles
