rounded ; mandibles stout, with the teeth of subequal length ; cheeks 

 not short, palpi white. Antennae slender and filiform, stouter in 



? beyond- the central white band, with basal flagellar joints elongate. 

 Thorax uuicolorous throughout, or with sternum nigrescent, and dull 

 with a discal mesonotal sulcus in addition to the deep notauli ; meta- 

 thorax rugulose, with only a centrally inflexed basal transcarina; 

 spiracles oval and apophyses wanting. Scutellum and postscutellum 

 red, coarsely punctate and not margined. Abdomen of <$ elongate, 

 of ? fusiform, finely punctate and dead black with apical half of the 

 shagreeued or subglabrous postpetiole and whole of the fifth to seventh 

 segments white; gastrocoeli of the subquadrate second segment small 

 and basal ; third strongly transverse ; terebra as long as the first 

 segment or a third of the abdomen. Legs black with all the calcaria, 

 apices of anterior femora and the inner side of their tibiae, dull 

 stramineous ; <$ legs paler, with the anterior trochanters also white- 

 Wings hyaline, in ? with a more or less deeply iufumate cloud in the 

 centre only of the wing, before the small and quadrate areolet ; stigma 

 and uervures nigrescent ; lower basal nervure a little autefurcal ; 

 nervellus opposite, intercepted at its lower third. Length, <$ 6, 



$ 7-8 mm. Of the twelve described Indian species of this genus 

 (including Cnjptus onustus, Walk.), this most closely approaches 

 G. (l/Wr//) ornatipennis, Cam., which has the niesothorax mainly 

 black, the alar infumation much broader, the metanotal base smooth, 

 etc. ; it is very like G. basilaris, Holmgr. 



Three females and a male from Durban in Natal were probably bred 

 together with a fourth female which is labelled, along with its host's 

 cocoon, by Bell Marley from the same locality, " host possibly

? only. A red species with the abdomen except basal segment, 

 sternum, with part of the liagellum and hind legs, black ; anus, 

 calcaria, a central flagellar baud and inner side of front tibiae, alone 

 white; mesouotum not centrally sulcate. Length, 8| mm. This 

 species too closely resembles the last to need a detailed description ; 

 therefrom it differs structurally in its more finely punctate and shining 

 scutellum, more coarsely punctate and convex metanotum with distinct 

 though not large apophyses, its distinctly bicariuate postpetiole of 

 which the central area is striolate and the lateral are punctate, and in 

 the more deeply and conflueutly punctate abdomen ; in colour it may 

 be known therefrom by its entirely red head, five basal antennal 

 joints and first abdominal segment which is not white-marked, by
