CHALCIDOIDEA BRED FROM GLOSSINA MORSITANS. 391 



irons is level, except where interrupted by the post-scapal hollow. This depression, 

 extending half-way from the scrobes to the anterior ocellus is on the lower two-thirds 

 deeply sunk at the sides, with sharply excavated walls, and medianly raised between 

 and behind the scrobes. At the apex it is broadly rounded, merging gradually with 

 the frons. There is another well defined edge, with a deep fall towards the malar keel 

 and the mouth-edge, between the eyes and the scrobes. The whole surface of the head 

 is finely reticulate, the pattern more flowing or striate on the post-scapal hollow. 



Mouth-parts ; labrum with six bristles ; mandibles similar, broad and stout, 

 narrowing apically, with three teeth, the lowermost acute, the middle one rounded, 

 and the uppermost nearly rectangular. Three rows of bristles externally on the lower 

 apical two-thirds. Maxillary palpus : stipes elongate, with thirty to forty bristles, 

 mainly on the outer side ; palpus (5 : 6 : 7 : 15) with the first joint bare, and at its 

 bafee, one-third of the last joint at its widest ; joints 2-4 covered with short stiff 

 bristles, 2 and 3 bearing in addition a large clear pustule (sense organs ?). There are 

 two or three strong hyaline terminal bristles (the longest not one-fourth of the last 

 joint) and one stout hyaline spur. The mentum bears about eighteen bristles. Labial 

 palpus (6:1:6) with all the joints bristly and the last swollen, the terminal bristle 

 two-thirds as long ; the lingua bears about twelve setigerous cells. 



Thorax : the whole surface refringent, unless otherwise noted, raised reticulate 

 and mostly with minute scattered glistening appressed bristles. Prothorax porrect ; 

 pronotum with two somewhat quadrate sclerites ; pre-episternite covered by overlap 

 of protergite and smooth. Mesonotum flat above, with sharp ridges (parapsides ?) 

 laterally. Side lobes curving downwards to the mesopleurae and nowhere dorsally 

 flattened. Scutellum about the same length as the mid lobe, but from above 

 apparently longer, as the thorax slopes more abruptly forward from the suture. The 

 abscissa of the scutellum on the suture is less than the width of either axilla, and the 

 bases of the scutellum and the axillae form a straight line. The sclerites of the axillae, 

 and the mid and side lobes do not fit perfectly, the gap between being triangular. 

 Axillae shghtly over two-thirds the length of the scutellum, and in the same plane. 

 Prepectus narrow and wedge-like, based posteriorly on the narrow and short mesepis- 

 ternite, which lies below the very large tegula. On the mesopleurae the short bristles 

 are placed principally antero-ventrally. Apically the scutellum is developed at the 

 sides into two short rounded lobes ; here the tips of the tegulae and the sharp entero- 

 lateral angles of the metanotum rest. Surface of the scutellum towards the ape?c 

 coarser in texture ; metanotum and propodeon smoother and almost shining, though 

 distinctly reticulate. Metanotum in the form of two triangular sclerites broadly 

 joined medianly and reaching far forward ; at their junction is a short keel and traces 

 of two others, one on each side. Propodeon like the metanotum, in two sclerites, 

 with large antero-lateral spiracles opening anteriorly. 



Legs : fore femur only moderately thick ; apparently without ventral fringe of long 

 bristles. The mid tibial spur is about five-sevenths of the first tarsal joint, which 

 bears nineteen teeth anteriorly and sixteen posteriorly ; the second has 6, 7 ; the 

 third 4, 4 ; and the fourth 1,1. There are also four teeth at the apex of the tibia 

 anteriorly. In the hind leg, the tibia folds up flatly against the femur, which is 

 posteriorly smooth and slightly grooved along its entire length. The apical tibial 

 spur is short. In all the tarsi the proportions approximately are : — 10, 5, 3, 2, 3.
