492 MR. A. G. BUTLER ON [Nov. 4, 



Damascus, but that is probably an exceptionally large example ; 

 there is no difference between a female from Damascus and one 

 from Huswab. 



" I have raised caterpillars of this on Capparis galeata." — J. W, T. 

 A caterpillar taken on the 14th March emerged on the 24th. 



35. Belenois leucogyne, sp. n. 



Allied to B.elisa and B. johannce. Size of B. severina : the male 

 above milky white : primaries as iu B. bogiiensis, with narrow 

 oblique black discocellular streak and tapering, internally zigzag, 

 external border enclosing five spots of the ground-colour, the second 

 largest ; secondaries with a marginal series of triangular blackish 

 spots indistinctly connected by a few dusky scales here and there : 

 under surface most like B. boguensis ; primaries milky white, the 

 apical or external border hrown, darker along its inner edge and 

 enclosing six primrose-yellow spots, one being placed within the 

 subcostal furca ; secondaries primrose-yellow, with a chain-like series 

 of four large spots of the ground-colour upon a brown ground, an 

 abbreviated brown irregular stripe from costa to second subcostal 

 branch. Female above sulphur-yellow ; primaries with black disco- 

 cellular bar and external border as iu B. boguensis 2 '■> secondaries 

 with narrow external black border and subcostal stripe ; four small 

 submarginal spots of the ground-colour ; primaries below reddish 

 brown towards apex ; seven lemon-yellow spots upon the external 

 border, otherwise as above ; secondaries pearl-white, streaked and 

 bordered with lemon-yellow, border brown ; otherwise as above. 

 Expanse of wings 55 mm.

36. Synchloe glauconome. 



Pontia glauconome, Klug, Symb. Phys. pi. 7. figs. 18, 19 (1829). 



Aden, 25th and 28th January, 1883; 5th and 12th February 

 (from chrysalis), 1884. 



" The caterpillar of this butterfly feeds in Aden on plant no. 42 

 (Cleome paradox a), but in the interior it feeds on no. 43 (^Diptery- 

 gium glaucum) ; it is generally distributed." — J. W. Y. 



S. iranica of Bienert, from Persia and Affghanistan, is closely 

 allied to this species ; on the upper surface it differs chiefly in the 

 larger white spots on the apical border of the primaries ; ou the 

 under surface, however, it is readily separable by the absence of the 

 green basi-abdominal patch on the secondaries, and the paler 

 yellower tint of the other green markings on all the wings. 



A discoloured chrysalis forwarded by Major Yerbury as possibly 

 that of Teracolus phisadia appears to me to belong to this species ; 

 it is of the usual form and shows the wing-pattern distinctly.

Eronia buquetii, var. arabica, Hopffer in Peters's Reise nach 

 Mosambique, Zool. v. p. 363, var. /3 (1862).
