SCHIZTOBEACON, gen. nov. 



Abdomen with seven segments, the third to sixth deeply, widely 

 •depressed in the middle ; the sixth with a semicircular incision in 

 the middle and with a wider incision on the sides of the apex, i.e., 

 trilobate ; the last segment broad, transverse ; the second with a 

 large, clearly limited triangular area. Eadial cellule long, narrow ; 

 transverse median nervure interstitial. Wings spotted. All the 

 abdominal segments longitudinally striated on the transverse 

 depressions. 



This genus cannot well be confounded with any of the genera of 

 the Braconince. The form of the abdomen reminds one of some of 

 the species of Spinaria, but that belongs to the Exotliecina. Apart 

 fi'om the peculiar structure of the sixth abdominal segment the type 

 of the genus might be referred to Ipkiaulax. 



SCHIZTOBKACON ORNATIPENNIS, Sp. nOV. 



Pale lemon-yellow, the antenna, front, vertex and upper half of 

 occiput, the middle lobe of mesonotum to shortly beyond the middle, 

 lateral entirely, scutellum, the greater part of the mesopleurse, apex 

 of mesosternum broadly, and the base of metapleurae broadly, black. 

 Wings yellowish-hyaline, the first and second discoidal cellules and 

 the parts beyond the first transverse cubital nervure smoky, more 

 hyaline along the second transverse cubital nervure ; basal two-thirds 

 of stigma luteous, the apical black. Antennae black, longer than the 

 body. 2 . 



Length 10 mm. ; terebra 4 mm. 



Southern Ehodesia. Sebakwe. 



Palpi testaceous. Head and thorax smooth ; the face covered 

 thickly with fuscous hair. Parapsidal furrows narrow, indicated at 

 the base only. Middle lobe of first abdominal segment rugose ; the 

 base with a smooth, oblique slope ; the second closely, longitudinally 

 striated on the middle area ; the sides irregularly wrinkled ; the 

 oblique lateral depression irregularly striated ; the raised, rounded 

 base of the segments are smooth ; the striae on the depressions are 

 strong, regular and longish; the lobes on the sixth segments are 

 smooth. The apical abscissa of the radius is slightly turned upwards 

 in front ; the recurrent nervure is received clearly in the apex of the 

 first cubital cellule. Tarsi and apical two-thirds of hind tibiae 

 blackish.
