558 New Forms of African Lepidqptera 



Antennae fuscous, head, thorax, legs and abdomen greyish-white, 



last four segments of abdomen fuscous above. Head and thorax above 

 yellowish. 



Length of fore wing : 16 mm. 



Habitat. — Ituri Forest, January, 1920, one $ ; Upper Lowa 



Valley, north side, September, 1921, one $ (type). 



Also a series in the British Museum from Uganda. 



The Lipaeid Geneea. 

 Stracena Swinh. and Sapelia Swinh. 



Stracena, Trans. Ent. Soc. Loud., p. 388 (1903) (type fuscivena 

 Swinh., Niger). 



Sapelia, I.e., p. 389 (1903) (type limpida Swinh., Niger). 



When collecting at Kinchasa on the Congo, Mr. T. A. Barns obtained 

 two Liparids " in cop." The £ agrees with Sapelia limpida Swinh., the 

 ? agrees with Stracena fuscivena Swinh. The sexes present the 

 characters of the two genera in the $ and ? respectively. 



It is evident that Sapelia will have to sink to Stracena. The 

 $ limpida Swinh. must be associated with the $ of some other form. 



Ptekothysanidae . 

 29. Hibrildes ansorgei Kirby albescens subsp. nov. 



Figured in Barns' " Across the Great Craterland to the Congo," 

 pi. Ixxx, fig. 10 ? , 1923. 



$ . Distinguished by the white instead of brown hind wing. The 

 white band of the fore wing is broader, more sharply defined, purer 

 white and reaches below vein 3. Hind wing with the black margin 

 narrower, and the white spot in 6 indistinct ; edge of white area more 

 deeply incised at the veins ; discocellular mark much heavier. 



Habitat. — Luvua Elver (east bank), 85 miles north of Lake Mweru, 

 ca. 3,000 feet, April, 1922, end of wet season, one ? taken in the daytime. 



$ . Closely resembles venosa Kirby, but appears to differ in the 

 broader apical band on the fore wing, this band closer to the margin and 

 reaching vein 4, and in the larger patch at the base of cellules 3 and 4. 

 The white band on the fore wing of the female described above is 

 represented here by an equally broad interspace between the edge of the 

 dusky apical area and the end of cell. 



One specimen, East Luvua Valley five days north-east of Lake 

 Mweru, 4,000-5,000 feet, March, 1922, middle of wet season.
