ON PARASITIC EYMENOPTERA. 581 



Clypeus broadly depressed, the apical margin raised. Propleurse shagreened, the 

 fore margin raised ; the smooth base of mesopleurae with 4 foveas, of which 

 the 3rd is the larger and more irregular, the part below covered with round, 

 not very deep, punctures, the middle with a broad striated band, widest above, 

 the rest smooth, shining ; metapleurse rugosely punctured. Pro-mesonotum 

 and scutellum strongly punctured ; the pronotum more closely than the rest. 

 Metanotum coarsely reticulated ; on the basal half of the metapleuras, on the 

 inner edge, is a curved oblique area, fully 4 times longer than wide and curved, 

 roundly inwardly on the innerside ; the sides are broadly rounded, without 

 projections. Basal segment of abdomen shining, the sides weakly punctured ; 

 the others are strongly punctured, except at the base and apes. On the hind 

 femora are 7 large, clearly separated teeth (the basal more widely separated 

 than the others) and 3 smaller, closely pressed apical. Hind coxae smooth and 

 shining above, shagreened and pilose below. The areola is about twice longer 

 than wide, rounded and narrowed at the base, transverse at the apex. 



This species may be known from marginata, Cam. and deesce, Cam. by the 

 pale, not bright lemon-yellow colour of the legs and tegulaB. The 3 may be 

 separated thus : — 



a. Middle of face without a smooth, shining, clearly denned 



plate; temples very short, underside of hind femora 



thickly covered with silvery pubescence deesce, Cam. 



b. Middle of face with a large, clearly defined smooth plate, 



temples not very short. 



legs bright lemon-yellow, clypeus raised in the centre; 



areola obliquely, sharply narrowed at the base marginata, Cam. 



legs whitish yellow ; clypeus broadly depressed ; 



areola bluntly rounded at the base nursei, Cam. 



Chalets megaspila, sp. nov. 

 Black, the tegulse and the legs, except the coxae, trochanters, the femoral 

 teeth and a large mark, longer than wide, on the middle of the outerside of the 

 hind femora ; the mark is slightly oblique, extends to the basal fourth and has 

 the base rounded \ they have 12 minute black teeth, the basal less distinct and 

 widely separated ; wings hyaline, the nervures black. $ . 

 Length nearly 5 mm. 

 Abu. 



Orbits, face and clypeus densely covered with longish white pubescence ; 

 closely rugosely punctured, the face more coarsely than the rest ; clypeus 

 smooth, except for a row of weak punctures in the middle ; the labrum smooth, 

 its sides raised. Mandibles closely rugose, smoother towards the apex. Tem- 

 ples distinct, moderately wide. Pro-mesonotum and scutellum closely rugosely 

 punctured, the scutellum more coarsely than the rest, the apex broadly biden- 

 tate, the lobes brownish. Metanotum deeply reticulated ; the reticulations in 

 rows ; there is no areola ; the sides broadly rounded ; roundly dilated below. 

 Basal segment smooth, shining, bare, the others closely, strongly punctured and 

 thickly covered with white hair. The 3 lower teeth on the femora are smaller,
