GEN. IDIOTEPHEA, Wan-. 



37. IDIOTEPHKA SIMPLEX, spec. nov. 

 (Plate XLL, fig. 2.) 



Superficially almost exactly like /. curvivena, the type of the genus, 

 but the antennae of the 3 are not bipectinate, but bear pairs of 

 pedicellate fascicles of cilia at right angles to the shaft ; and secondly; 

 the neuration of the hindwing is perfectly simple, and no distortion 

 of bhe veins is visible ; the present insect must therefore be placed in 

 a second section of the genus, characterized by this difference in 

 neuration and in the structure of the antennae of the <? . The type 

 of curvivena came from the R. Niger, and I have seen a second from 

 the Gold Coast. The example of /. simplex is from Cape District, 

 Kalk Bay, South Africa, captured in March, 1901, by E. Lightfoot. 

 Besides the above-mentioned structural differences, I. simplex differs 

 also in being somewhat larger, more densely speckled with dark 

 atoms and with larger black cellspots ; the hindwing is grey-speckled 

 throughout, whereas the basal in curvivena is dull whitish and the 

 terminal border dark. The lobe at anal angle of hindwing will at 

 once separate curvivena. 



GEN. PETRODAVA, Wlk. 



38. PETEODAVA ATRISIGNATA, spec. nov. 

 (Plate XLL, fig. 4.) 



Forewing : Brownish olive, with a few dark transverse strigae ; 

 costal edge whitish ; a small black cellspot ; a sinuous partially 

 interrupted outer black line, plainest at each extremity ; fringe 

 concolorous. 



Hiiidiviny : Paler, more yellowish olive, without the brown tinge ; 

 a black cellspot and outer line, the latter only plain at extremities, 

 followed at costa by two small brown-black blotches ; fringe brown- 

 mottled. 



Underside yellowish olive, the strigae thicker and blacker ; costa 

 whiter ; outer line black throughout, followed by slight grey scaling 

 especially on inner margin of forewing and at costa of hindwing. 



Face, second and third segments of palpi, and antennal shaft 

 white ; vertex and thorax concolorous with forewings, abdomen with 

 hindwings ; legs white thickly freckled with black. 



Expanse of wings : 33 mm.
