NOTES OX AFRICAN CHALCIDOIDEA— III. 233 



clothed with evenly set, short stiff bristles, externally with only a few such bristles, 

 chiefly at the apex and along the dorsal edge ; 5-6 long curved bristles on outer 

 ventral edge. Sense-organ broad and covering nearly all the ventral or subventral 

 edge of the scape ; apically and basally it lies on the edge, while its median area lies 

 above the edge. Pedicel two-fifths of scape, narrow (2 : 1) ; the ring joint is possibly 

 double, as two thin laminae, of which only the first appears to be fused with the visible 

 joint, intervene between it and the first of the funicle ; funicle gradually expanded, 

 with equal joints, but as the last pair are sub-quadrate and pedunculate, they appear 

 shorter than the first, which is much longer than broad (3:2); club joints in ratio 

 4:5:6 (reckoning the spur) ; whole club much swollen, about twice as broad as the 

 first funicular joint. The first funicular with no sensoria externally, but one on the 

 inside and another ventrally ; the second funicular bears four, one on dorsal, ventral, 

 inner and outer aspects respectively ; the third has six (1, 2, 1, 2) ; the fourth eight 

 (1, 3, 1, 3). In the segments of the club the arrangement is, (1st) 1, 6 (outside), 1, 4 ; 

 (2nd) 1, 8, 1, 6 ; (3rd) 1, 3, 1, 2. Mouth-parts: labrum with four clear stout bristles 

 (2, 2). Mandibles tridentate, the outermost tooth heaviest and most acute, separated 

 deeply from the second, third tooth rounded and inconspicuous ; across the mandible 

 runs a transverse row of four bristles ; maxillary palpus four times as long as the labial, 

 with one long median outer bristle and a shorter subapical ; at the apex stands a 

 third, long and stout, with a fourth very minute alongside. The lingua appears to 

 have only four setigerous cells. 



Thorax. —The pattern of the notum is, as a whole, fine and long drawn out. 

 Mesonotum and scutellum with distinct impressed lines. Inside each parapsidal 

 furrow are 4 stout bristles of which the first stands in front of the suture and the last 

 beyond one-half ; the side lobes, with reticulations more nearly isodiametric, bear 

 about 10 bristles ; axillae bare, with similar pattern to that of side lobes ; scutellum 

 quadrate, with two well-defined furrows enclosing rather more than the median third, 

 where the pattern is faint, while on the side areas it is more definite. The mid-area 

 shows besides a very ill-defined central depression or weak impressed line. The post- 

 scutellum (notum of the morphological metathorax) is honeycombed or deeply pitted 

 and declivous about the middle line ; pleurae long and smooth. Propodeon with 

 one median keel (a fusion of two) and two lateral, starting anteriorly just inside the 

 large oval spiracles and converging posteriorly to enclose the peduncle ; at the 

 anterior end of each lateral keel a ridge (at first thick, then thinning rapidly) rises on 

 the pleura extending posteriorly and downwards, while below the spiracle is another 

 much shorter pleural ridge. The spiracle thus lies in a rather deep narrow sulcus 

 which extends to the suture with the metathorax. The notum of the propodeon is 

 also sunk considerably on each side before the lateral keels. Between these hollows 

 and the spiracle the surface is raised, crescenbic, broadest behind. Except round the 

 spiracle and about the middle of the central keel the notum and pleurae of the pro- 

 podeon are coarsely raised reticulate. There are five or six bristles on the pleurae 

 below the spiracle. On the mesosternum the prepectus is somewhat long and very 

 coarsely raised reticulate ; on the sternum proper the reticulation is little raised ; 

 the pleurae are rougher.
