TEANSFOEMATIONS OF SOME SOUTH- AFEICAN LEPIDOPTEEA. 167 



Pupa. Pale brown, with darker dorsal and lateral lines, and with a pinkish suffusion 

 on the wing-covers ; it is suspended by the tail to the stem of the food-plant. 



The imago is common all over Natal and in the Transvaal. 



Both of the foregoing larvae present a striking resemblance to the larva of an Indian 

 species, Pseudergolis wedah (Kollaij figured by me in the ' Journal of the Bombay 

 Natural History Society,' vol. xi. plate U. tigs. 9 «, 9 b (1897), the latter larva differing 

 from them only in structure in the absence of the spiny tubercles. 



Crenis boisduvali Wallengren 1 . (Plate VI. figs. 9, 10, larva.) 

 Crenis boisduvali Wallengren, Rhop. Cam-, p. 30 (1857). 



Larva. Head fuscous ; body pale brown laterally, merging into ferruginous dorsally ; 

 a thin black dorsal line ; each somite with six small black tubercles, furnished with 

 small black spines, those on the 10th, 11th, and 12th somites well branched; legs and 

 claspers fuscous. 



Feeds on inkberry (Exceecaria reticulata Miill.-Arg.), a very common tree on the 

 Flat, Durban. I am indebted to Mr. W. Haygarth for a drawing of this larva. 



Pupa. Pale brown with dark fuscous markings. 



The time occupied by the transformations was 14 days in larval stage, and one week 

 to 14 days in pupal stage. 



The imago is a common butterfly in gardens on Berea, Durban, where it may be 

 seen flying amongst bushes quite late in the afternoon. 



Crenis natalensis Boisduval. (Plate VI. figs. 11, 12, 13, larva; 14, 15, pupa.) 

 Crenis natalensis Boisduval, Dclegorgue, Voy. Afr. Austr. ii. p. 592 (1847). 



Larva. Head and body bright ferruginous, head surmounted by a stout tuft of 

 ferruginous hairs ; black dorsal and spiracular lines ; each somite bears six small 

 tubercles, on which are planted short spines ; legs and abdominal claspers ferruginous. 

 The figures are drawn from sketches made by Mr. W. Haygarth. 



Pupa. Pale brown with dark fuscous markings ; suspended by the tail from the 

 stem of the food-plant. 



Larva feeds on inkberry (Excwcaria reticulata Miill.-Arg.). 



The transformations occupy a similar period to those of C. boisduvali. 



The imago does not, in my experience, seem so common as the latter insect, but its 

 habits are the same. 



1 [For a full description of both larva and pupa, see Eev. H. A. Junod, in Bull. Soc. Sci. Nat. de Neuehatel, 

 xx. p. 21 (1892). M. Junod describes specimens observed in the Delagoa Bay district, and notes that 

 the larva is of a greenish tint and gregarious habitually until after its second moult ; and that the pupa 

 presents two forms, one pearly green and almost without markings, while the other is brownish grey with 

 intricate black linear markings. — E. T.]
