 GEN. NEMOEAEA Rob. Desv. 



NEMORAEA CAPENSIS, Schiuer. 



Schiuer has described under this name a good species which does not 

 belong to the genus Nemoraea because the cubitus of the 4th nervure 

 has no prolongation, and that there are 3 sternopleural setae ; this 

 last character removes it from Winthemia R. D. and from Serico- 

 plinronnja Aust. Schiner's species bears on the tergum the 3 normal 

 pairs of acrostical setae in front of the suture ; it is therefore not a 

 species of Enifxtia. It most nearly approximates the genus Chaetolyga 

 Roud., Grieschu. s. strict., but the hairiness of the genae is found, in 

 Schiuer's type, only on the upper part, whence it descends a little along 

 the facial ridge. In two other Cape examples this hairiness is wanting, 

 or is reduced to some ciliae under the frontal setae. One o^ these ( $ ) 

 belonging to the Vienna Hofsmuseums, bears the label " dasyops 

 Wied.," but does not correspond to Wiedemau's description : " on the 

 pleurae the hairiness is blackish ; the legs are black with the tibiae 

 brownish red, etc." To these characters must be added that C. 

 capensis Sch. bears 2 pairs of vertical setae, no ascending frontal 

 setae ; 4 dc. on the thorax ; 4 long median spaced marginal setae on 

 the 2nd abdomin segment ; claws of all tarsi elongate. 



G-EN. ZENILLIA Rob. Desv. 



ZENILLIA SORDIDA, n. sp. 



Similar in coloration to Antistasea fiinbriata Bish ; the size is also 

 the same ; but it is plainly allied to Zenillia barbata Rond., from which 

 it differs in small details only. Black, little shining, weakly sprinkled 

 with ashy on the thorax seen from behind, when there are discernible 

 4 black lines, with the median ones much spaced. On the abdomen, 

 segments 2 and 3 have a wide, but little denned, similar ashy band 

 narrowing on the 4th. Width of the frons equal almost to ^ that from 

 eye to vertex ; the orbits and also the peristome have a bright steel- 

 grey sheen ; the frontal opaque brown band is very wide in proportion 

 to the orbits ; the dark cinereous genae are narrow ; the peristome is 

 about -J- of the width of the eye. Palpi and antennae black, in the 

 latter the 2nd joint is elongated, the 3rd is hardly 3 times as long as 

 the 2nd ; chaeta black, 2nd joint a little elongated. Epistome greyish- 

 blue. Upper occiput with small I (lack setae behind the ciliae ; the 

 facial ridges bear on ?- of their lower part slender, closely set setae 

 erect in front as in Z. barbata Rond. ; the frontal setae, more robust in
