254 NOVITATES ZOOLOGICAE XXIII. 1916. 



the dark patch of the head in front of the antennae being more diffuse than in A. d. 

 donysa and contrasting less with the occiput, and by the grey marginal area on the 

 underside of the forewing being less sharply defined. — Type from Sitio, Costa Rica, 

 June (W. Schaus). 



14. Oxyambulyx substrigilis wilemani subsp. nov. 



Alis anticis macula costali subbasali notatis. 



Hab. Philippine Islands: Manila, one S, September 9. 1912, and one ?, 

 July 12, 1912, collected by A. E. Wileman, who has kindly presented this pair to 

 the Tring Museum. 



Both sexes have a distinct rounded subbasal costal spot on the forewing above, 

 which is not present in the other forms of 0. substrigilis. The spot is larger in the 

 ? than in the <$ . The marginal band of the forewing is somewhat broader before 

 the middle than in the other races, and, on the underside, also more strongly 

 abbreviated posteriorly. The ventral process of the harpe of the J 1 is very broad. 



15. Pseudoclanis grandidieri comorana subsp. nov. 



3. Fascia nigra alarum posticarum e maculis ovatis plus minus contiguis 

 composita. 



Hab. Comoro Islands : Grande Comoro (L. Hnmblot), one <$ in Mus. Tring 

 received from Monsieur Charles Oberthiir. 



Forewing less falcate than in P. g. grandidieri, from Madagascar, with a row 

 of black submarginal dashes on the veins. Black band of hindwing more proximal, 

 being much narrower than the marginal area, incised between the veins, separated 

 into spots between costal margin and BA On the underside the grey marginal 

 area of the forewing less sharply defined below the apex than in P. g. grandidieri. 

 Upper apical process of harpe shorter than in P. g. grandidieri. 



16. Leucophlebia afra Karsch (1891) 



When writing our " Revision" of the Sphingidae we had only five specimens of 

 this species in the Tring Museum ; now we have thirty-nine. A recent examination 

 of this material has revealed the two facts : (a) that there are several geographically 

 separated forms of Leucophlebia with black-banded abdomen, and (b) that L. 

 xanthopis Hamps. (1910) is one of them. 



We have no ? $ , and the British Museum possesses but one specimen of that 

 sex. The following remarks, therefore, refer to the male sex only. 



The specimens from the various faunistic districts exhibit more or less con- 

 siderable differences in the antennae and genitalia, the individual variation being 

 slight as compared with the geographical variation. Our attempt to divide L. afra 

 into its geographical components must be considered provisional. The specimens 

 on which we base these notes may represent more subspecies than we at present 

 think there are before us. But as we have only single specimens from several of 

 the localities, we advisedly abstain from going beyond the obvious lines of division. 



a. L. afra edentata subsp. nov. (Text-figs. 5, 6) 



Valvarum processus dorsalis magnus, harpa edentata. 



Hab. Four <$ <$ from : Gambaga, Gold Coast (Dr. Bury), type ; Lokoja, 

 Nigeria, October 1904 (D. Cator); Raja, Bahr-el-Ghazal, July — August 1911 (Dr.
