Hymenoptera. 305 



narrow one along the fore margin of the 1st cubital, from the 

 base of which a similar streak runs obliquely to the 2nd cubital 

 cellule, and a cloud along the outerside of the 3rd transverse 

 cubital, and of the 2nd recurrent ner.vures. The sides of the 

 incision on the scutellum are straight, oblique, not cui-ved and 

 incised in the middle as iu G. scuteUari.s, but more as in G. picta ; 

 but not so deep and without any widening in the middle, at the 

 base ; the outer sides are straight, oblique. The centre of the last 

 abdominal segment is roundly transverse, followed by a rounded 

 depression, the, autersides being dilated into projecting teeth; the 

 epipygium is roundly, broadly dilated in the middle. 



Length 15 mm. Male. 



Katberg. December. Miss Sole. 



The middle joints of the flagellum are roundly dilated below ; 

 the last is laterally obliquely compressed ; the 3rd is about one- 

 third longer than the 4th. Labrum closely and strongly punctured; 

 the upper three-fourths are clearly, widely, deeply furrowed in 

 the middle ; the upper half projects largely over the lower. 



This species might be taken for a large variety of G. scatcl- 

 laris, F., but the very different form of the apex of the scutellum 

 distinguishes the two ; in scutellaris the middle is incised, and the 

 sides roundly curved, ending in a sharp point ; scutellum, too, 

 wants the patch of pubescence : G. Jaegerskiveldi, Morice, has a 

 patch of pubescence on the scutellum, but it has the latter formed 

 as in Scutellaria. According to Morice the results of the Swedish 

 Zool. Exped. to Egypt and the White Nile (No, 11, p. 9) none of 

 the previously described species of Gricosa possess this patch (but 

 S3e Vachal, Ann. Soc. Ent. Fr., 1903, p. 381) but it is to be found 

 in the Cape G. picta., Sm. The pubescence on the latter is blue, 

 and the scutellar incision is wide and not clearly defined as in 

 Scutellaria ; it is also much larsrer.
