3 times longer than it is wide at the apex, nearly as long as the 

 2nd and 3rd segments united. Apical segment sparsely, but dis- 

 tinctly, punctured above and on the sides, the top clearly margined 

 laterally. Radial cellule short, reaching half way between the 

 stigma and the apex ; the apical abscissa of radius straight, not 

 oblique, transverse cubital nervure received in the middle of the 

 radial cellule ; the transverse discoidal shortly, but clearly beyond 

 the middle. 



Has the form of a Dasyproctus, but the petiole is not quite 

 so long as it is in that group, and in it the mandibles are 

 tridentate. 



Trypo.vylon capensi\ sp. nov. 



Black, the mandibles rufous, the palpi pale testaceous ; wings 

 hyaline, the apex narrowly clouded, the stigma and nervures 

 black. Face, clypeus and pleurae thickly covered with silvery 

 pubescence. Front opaque, obscurely striated ; from the upper 

 part of the eye incision it becomes gi'adually narrowed to a point 

 at the apex, but is not keeled ; in the centre is a furrow which is 

 more distinct above than below. Eyes slightly converging below. 

 Hind ocelli separated from each other by a less distance than 

 they are from the anterior. Above the eyes are separated by 

 slightly more than the length of the 3rd antennal joint. Last 

 antennal joint slightly shorter than the preceding two united. 

 Thorax almost smooth. Median segment with a wide central, 

 bordered by equally wide curved lateral furrows ; the central is 

 closely striated, except at the top and bottom ; the lateral have 

 some irregular striae ; apical slope irregularly striated and thickly 

 covered with silvery pubescence. Petiole slightly longer than the 

 thorax and the following 3 segments united. Radial cellule long 

 and narrow ; the apical abscissa of radius fully 3 times longer 

 than the basal. Fore legs brownish in front ; the last joint of 

 fore tarsi and the 4 front calcaria pale testaceous, the hind calcaria 

 black. The 2nd abdominal segment is more than double, the 

 3rd and 4th not double so long as wide at the apex. Third antennal 

 joint distinctly longer than the 4th, more than twice the length of 

 the pedicle.
