Descriptions of New Species of Parasitic Hymenoiitera. 27 



longer than wide ; the third joint is shorter than the fourth. Collar' 

 as seen from above, broader than long. Mesonotum strongly ru- 

 gosely punctured ; the sides of the lateral lobes closely finely 

 aciculated-punctured, with a row of large punctures down the 

 middle. Scutellum finely, aciculated punctured. Metanotum with 

 a stout keel down the centre ; this keel is bordered by short, clearly 

 separated transverse keels on both sides ; the rest is irregularly 

 rugose, more or less longitudinally striated, especially above, and 

 thickly covered with white pubescence. Mandibles rufous, the teeth 

 black. Hind coxge three times longer than wide, finely transversely 

 striated ; the hind legs black ; the basal half of the femora and base 

 of metatarsus rufous. Wings hyaline, the stigma testaceous ; the 

 posterior discoidal cellule is not much shorter than the upper ; the 

 nervures are received at the same distance from the base and apex. 

 I have G. lissoceplialus from Cape Colony. 



Gasteruption spilopus, sp. nov. 



Length 16 mm. ; terebra 15 mm. ? . 



Cape Colony. Neighbourhood of Cape Town. 



This species resembles closely G. dunhrodijense, Cam. (Records of 

 the Albany Museum, i. 159), but may be separated by the radial 

 cellule being shorter and wider, by the posterior discoidal cellule 

 being of equal width, whereas in dunhrodijense it is distinctly nar- 

 rowed posteriorly, the head is broader and shorter, the hind ocelli 

 are not so widely separated from each other as regards their separa- 

 tion from the eyes, the first abdominal segment is longer and thinner 

 and the four anterior legs are not whitish yellow in front. 



Reddish brown ; the front, vertex broadly in the middle, the lower 

 part of the hind orbits, the greater part of the middle lobe of meso- 

 notum, metanotum, a large triangular mark on the propleurae, basal 

 half of mesosternum, the top and base of metapleurae, and the fourth 

 and following segments of abdomen, black. Antennae dark-red, the 

 second, third, and base of fourth joints black. Legs coloured like 

 the body ; there is a yellowish-white band on the inner side, near 

 the base of the hind tibise. Wings hyaline, iridescent, the stigma 

 dark testaceous, the nervures darker coloured. ? . 



Length 16 mm. ; terebra 13 mm. 



Head smooth ; the apex of the clypeus with a semicircular depres- 

 sion and with a shorter, wider depression on either side. Apex of 

 mandibles black. Head thickly covered with silvery pubescence. 

 Malar space as long as the second antennal joint. First atennnal
