(10). 15. Metathorax evenly scabrous ; internal orbits normal. 



testaccus, Mori. 



(l- r >). 16. Metathorax trans-striate throughout ; internal orbits elevated. 

 (LS). 17. Pace and frons reticulate ; clypeus normally convex. 



Celoeno, sp. nov. 

 ( 17). IS. Face and frons finely punctate ; clypeus very convex. Mllo, sp. nov. 



GORYPHUS CORNIGER, Sp. UOV. 



V only. A not very stout, black species with white markings; the 

 thorax and head red, and terebra as long as basal .segment; frons not 

 centrally carinate. Head, four basal anteunal joints, thorax except 

 sternum, frenum and basal area, sides of first segment and disc of hind 

 coxae, red; rlagellar band, apex of second segment and anus from apex 

 of fifth, calcaria, anterior coxae beneath and inner side of front leg.N, 

 white. Very closely allied to U. Lisnlctilut, but differing therefrom in 

 its centrally scabrous postpetiole, the colour of the coxae and hind 

 femora, and in the usually apically white-margined second segment. 

 Before its apex the clypeus is produced into a vertical and sub- 

 acuminate pyramidal tooth. Length, 8-9 mm. 



Taken with the next species during May in Zululand. 



GORYPHUS LOBATTJS, Sp. UOV. 



, only. A somewhat stout, black species with white markings ; the 

 thorax entirely red, and terebra nearly as long as abdomen ; frons 

 nut rally carinate. Prom my description of the female G. trisulcatus 

 (Ann. 8. Afr. Mus. 1916, p. 372) it differs only in the following 

 particulars: Head obliquely constricted behind the eyes; antennae no 

 stouter beyond their white band ; mesouotum not disc-ally sulcate 

 between the notauli ; abdomen with apex of second but not of first 

 segment white, the fifth and sixth immaculate black, and terebra as 

 long as abdomen excepting basal segment ; calcaria not white ; wings 

 hyaline. Length, 9 mm. The structure of the penultimate hind 

 tarsal joint, which is centrally cleft nearly to its base and strongly 

 pectinate, is unique in my experience and somewhat resembles that of 

 tipilocryptus females. 



Mfougosi in Zululaud, taken by W. E. Jones during May, 1916. 



GORYPHUS CINCTITIBIA, sp. nov. 



$ only. A somewhat stout, black species with sparse white mark- 

 ings ; the thorax and head entirely red, and terebra nearly as long as 

 abdomen ; frous centrally carinate. Nothing but the conformation of 

 the areolet convinces me of specific distinction from G. lobalus. The
