4. GRACILENTOR, Sp. n. 



A slender, testaceous species with the head, antennae, and anus 

 all white-marked black ; hind tai'si nigrescent throughout. Head 

 transverse-oval and posteriorly nearly as broad as the not very 

 prominent eyes ; flavous with the occiput, vertex, and frons black ; 

 frontal orbits to vertex citrinous ; occipiit abruptly declivous be- 

 hind eyes and, like the centrally carinate frons, closely punctate ; 

 face and clypeus flat, closely and confluently punctate, not dis- 

 creted and the latter centrally depressed befoi'e its apical margin ; 

 labrum exserted, mandibles very slender with the teeth piceous. 

 Antennte filiform and serrate, black with scape and underside of 

 basal half rufescent ; flagellar joints 16-23 white; apices desunt. 

 Thorax cylindrical and substramineous with no notauli, apophyses 

 nor arose ; areola represented by two slight longitudinal carinje. 

 Scutellum dull, but slightly convex, carinate to apex. Abdomen 

 sublinear, much longer than head and thoi-ax ; basal segment 

 linear with the obsoletely punctate-aciculate postpetiole hardly 

 broader ; gastroca^i very small ; anus black from near base of the 

 fifth segment with the seventh, apex of sixth and the stout 

 valvulpe, white. Legs slender and somewhat elongate. Wings 

 narrow, flavescent-hyaline ; stigma luteous; areola pentagonal, 

 broad above; radial cell elongate and narrow. Length, 14-15 mm. 

 d" only. — The outline of the abdomen is curiously like that of 

 MesolepUis males. — Found at Howick in Natal about 1904, by 

 J. P. Cregoe. 



ISCHNOJOPPA. 



Kr-eichbaumer, Entom. ISTachr. xxiv. 1898, p. 82. 



This distinct genus needs more revision than I am at present 

 able to eff'ect. It was erected for the reception of a species of 

 Joppid with elongate metapleural spiracles, occurring in both 

 India and Senegal ; and I have shown that Chinese, Bornean, 

 and Australian examples are not structurally distinct (Revis. 

 Ichn. iv. 1915, p. 97). Dr. A. Roman finds tYi&t Ischnus melano- 

 pygas Holmgren and its variety belong here (Entom. Tidskr. 

 xxxi. 1910, p. 172); and it seems nearly certain that the tAvo 

 kinds described under Ischnus by Tosqviinet in 1896 must also be 

 included, on account of their elongate thoracic spiracles — thus 

 Africa will be left with but a single Ischnus-ST^Qcies. (/, trochan- 

 teratios Rurgst, Tijds. v. Entom. Iv. 1912, p. 267; Tunisian 

 Hym. 1913, p. 15, § ). Szepligeti brought forward two new 

 species of Ischnojojypa from Kilmanjaro in 1910, and two more 

 from Java (Leiden Mus. Notes, xxix. p. 235) in 1908: also, I 

 have added a couple (Ann. S. Afr. Mus. 1916-17), giving the 

 total of nine known kinds, of which seven ai"e African. Some 

 synonymy may be expected.
