16 THE ENTOMOLOGIST'S RUCORD. 



joints, scape nearly a third of the total length, swollen at the base, the second 

 joint nearly twice as long as thick, obconical, funicle gradually thickened from the 

 third joint to the last which is conical, third joint slightly longer than thick r 

 fourth to ninth joints distinctly transverse, tenth joint twice as long as thick. 

 Legs dark brown except the coxas, the tibise at the base and the tarsi, which are 

 reddish. There is a dense fringe of long white hairs on each side of the rnetapleuraa 

 pointing backwards and covering the sides of the base of the abdomen. Propodeon 

 narrowly margined and having a few deep striations especially obliquely on each 

 side from the base to the inner side of the lateral acuminations, and forming a 

 trapezoidal area in the base of which is the small spiracle.

Diapriid^e. 



Lnxotropa fuliginosi, sp. n. 



Female. Length l'7mm. Antenna l'lmm. Black, smooth and shining, 

 with a mass of long whitish pubescence on the lateral corners of the pronotum, on 

 the dorsal surface of the petiole and on the metapleurae. Legs entirely bright 

 orange-red. Antenna: reddish-brown except the club which is black. Antennae 

 with the scape stout and cylindrical, as long as the five following joints, together, 

 second joint obconical, twice as long as thick, third joint longer than thick, 

 gradually thickened from base to apex which is as wide as the second joint, fourth 

 to ninth joints transverse, moniliform, tenth to twelfth joints more than twice as- 

 thick as the rest, forming a club which is as long as the scape, tenth and eleventh 

 joints globular, the eleventh distinctly transverse, the twelfth joint tapering to a 

 rounded point, longer than thick. Wings atrophied, reaching just beyond the 

 petiole, the forewing with a pale yellow marginal vein ending in a dark brown 

 knob or stigma and extending to three-fourths the total length of the wing, the 

 part beyond the stigma and immediately below it very pubescent, the rest hyaline 

 and glabrous. Hindwing linear, almost threadlike but slightly wider at the tip 

 and about as long as the forewing. Head wider than the thorax and about as wide 

 as the abdomen, subsquare, wider in front. Mesonotum semicircular but as long 

 as wide at the base. Scutellum with a deep depression in front next to and 

 running into the mesonotum. Propodeon with a raised emargination all round 

 ending in a prolonged blunt point or horn on each side, with a raised ridge in the 

 centre from front to back which is widened basally and raised there to a knob-like 

 point in the centre of the widened boss. The apical margin with a single tooth in 

 the centre. Abdomen more than twice as long as wide, flat above, almost parallel- 

 sided and somewhat truncate at the apex, petiole a little longer than wide, second 

 segment covering at least three-fourths the total length excluding the petiole. All 

 the tibise very slender at the base and gradually thickened to the apex.

Platygasterim: . 

 Synojieaa fuscicola, sp. n. 



Female. Length l'lmm. Alar expanse 2'lmm. Dull black, with white 

 hairs at the base of the mesonotum on each side in a fringe, on each side of the 

 scutellum thinly, on the lateral edges of the propodeon densely, on the metapleurse 

 all over densely, and on the base of the abdomen above on each side and ventrally 

 densely. Legs and antennas (except the club which is piceous) bright yellow. 

 Wings, except at the base below the short marginal vein, covered with short dark 

 hairs, almost hyaline. Tegulae prominent and fuscous. Head transverse, finely 

 and -mallowly alveolate, ocelli in a slight curye, wide apart, the outer ocelli very 

 near to the eyes. Pronotum broadly visible from above from one tegula to the 

 other for about the same depth all round. Mesonotum convex, finely rugose, with 

 two parallel striae from front to back frequently interrupted — like dotted lines — ■ 

 roughly dividing the surface into three equal parts and with a slightly raised knob 

 oi' pimple mther shining in the centre immediately in front of the scutellum and 

 another similar knob on each side between this and the tegula but nearer the latter 

 and with a row of short striae between each. The awl-shaped prominence of the
