obscure hyaline cloud on the apex. Face and clypeus opaque, 

 coarsely alutaceous, covered with short white pubescence ; the front 

 and vertex more coarsely alutaceous, obscurely transversely striated. 

 Middle of mandibles with a red band. Abdominal petiole long and 

 narrow, as long as the second and half of the third segment united ; 

 the spiracles prominent, smooth, the apex of post-petiole aciculated- 

 striated, bordered by fine keels ; the second and third segments 

 closely longitudinally striated-aciculated. Median segment deeply 

 depressed at the base ; there are three rows of arese of five each ; 

 the areola large, wider than long, its base bluntly rounded, the apex 

 transverse. <? . 



Length 5 mm. 



Cape Colony. Port St. Johns. 



This species differs essentially from L. nigriceps, Cam., the type 

 of the genus, in the for-m of the areola ; but this may not, in this 

 group of the Hemitelini (readily distinguished by the absence of an 

 areolet in the fore wings), be of generic importance. The two species 

 are readily separated. 



Areola clearly longer than broad, extending to the posterior 

 median area ; wings hyaline, a narrow cloud at the stigma, 



antennal scape testaceous n'ujncvpit. 



Areola wider than long, separated from the posterior median 

 area by one longer than wide ; wings smoky, the basal third 

 hyaline canalicitlata. 



As regards the other group, I give a generic description of it, 

 based on females, the only sex known to me. Of the other section 

 I only know males. 



Antennae 28-jointed. Metanotum with a distinct petiolar area, an 

 areola longer than wide, obliquely narrowed at the base, transverse 

 at the apex ; and a large posterior median area, the keels of which 

 curve round the sides ; the lateral areae are indistinctly defined ; the 

 base of the segment is obliquely depressed in the middle. Abdo- 

 minal petiole long, longer than the second segment ; it and the 

 other segments are closely strongly striated ; the second segment 

 has a wide, curved transverse furrow near the middle ; there are 

 eight segments ; the second and third are contracted laterally at the 

 apex ; the ovipositor is as long as the apical four segments united. 

 Pai'apsidal and sternal furrows distinct. Clypeus not separated 

 from the face. Mandibles bidentate, the teeth almost equal in 

 length. Wings without an areolet ; the recurrent nervure is 

 received beyond the transverse cubital ; transverse basal nervure 

 interstitial. Eadial cellule wide at the transverse cubital nervure ;
