NEW GEOMETRIDAE AND DIOPTIDAE IN THE 

 JOICEY COLLECTION. 



By LOUIS B. PEOUT, F.E.S. 

 (Plate XXV.) 



The miscellaneous species here figured — chiefly African Geometridae 

 — have already been described in No. 2 of the present volume (pp. 252- 

 269), together with Callioratis abraxas Feld. grandis Prout, which is 

 so unmistakable that a figure is superfluous. One addition, however, 

 has to be made, a $ of the interesting Nothabraxas barloivi (pi. xxv, 

 fig. 14) having been received while No. 2 was in the press. The 

 description is as follows : — 



Nothabraxas barlowi Prout, 3 . 



Nothabraxas barlowi Prout, Bull. Hill Mus., 1 (2), p. 264 

 (1922), 5 (Nyasaland). 

 $ , 46 mm. 



Paler than the $ , the other distinctions in markings probably — in 

 view of the known variability of the group — individual only. Fore 

 wing with distal border of basal patch more vertical, midcostal patch 

 smaller, not reaching so far beyond the discocellulars ; cell-mark 

 wanting ; distal patch rather broader and extended to tornus. Hind 

 wing almost without black maculation, excepting some rather asym- 

 metrical midterminal spots.
