184 TRANSFORMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTERA. 



The number and disposition of the long spatulate filaments seem to vary (as do the 

 claret-coloured spots) in different specimens. The life-size figure (fig. 18) of the larva 

 was drawn by me from a larva at present in my possession, and has only six filaments 

 on the 4 tli and 5th somites, while the enlarged figure was drawn by me from an 

 enlarged sketch of another individual, and it will be seen that this specimen has, in 

 addition to the filaments already mentioned, four pale whitish filaments subdorsally and 

 laterally on 6th and 7th somites. 



In ' Fauna of British India : Moths,' by Sir G. F. Hampson (vol. ii. p. 578), a figure 

 is given of the larva of Tinolius eburneigutta Wlk., which is, so far as one can judge 

 from a sketch, practically identical in structure with the larva of the South- African 

 form " cinctigutta'' 1 



Family GEOMETRID^E. 



Petovia dichroaeia Herrich-Schaeffer. (Plate VIII. figs. 9, larva ; 10, pupa.) 

 Petovia dichroaria Herrich-Schaefifer, Aussereur. Schmett. f. 189 (1854). 



Larva. Head dark fuscous ; body pale green, marked by narrow, dark fuscous, 

 transverse lines dividing the somites ; a dark fuscous thin dorsal line, broadest where 

 it unites with the transverse lines ; a thin light brown spiracular line ; legs fuscous 

 black ; claspers pale brown. 



Pupa. Pale fuscous-brown, with dark fuscous markings. 



Larva feeds on the "wild medlar," Vangveria infausta (Burch.), Natural Order 

 Bubiacete. 



This species was reared at Durban by Mr. W. Haygarth, who has kindly presented 

 me with a coloured sketch of the larva and pupa. 



Euchloris devocata (Walker). (Plate VIII. figs. 5, imago ; 6, 7, larva ; 8, pupa.) 

 Geometra devocata Walker, Cat. Het. B.M. pt. xsii. p. 514 (1861). 



Larva. Bright bluish green, paling to whitish laterally ; a fine dark green spiracidar 

 line, with an indistinct white line above it ; abdomen, legs, and claspers darker green ; 

 above the head on 1st somite two green tubercles. 



Fig. 7 shows the larva in the position in which it rests, simulating a stem of the 

 food-plant. 



Pupa. Pale brown, of the usual shape. 



Larva feeds on the "wild medlar,'' Vangueria infausta (Burch.), Natural Order 

 Bubiaceae. 



This species was reared at Durban by Mr. W. Haygarth, who has kindly presented 

 me with a coloured sketch of the larva and pupa.
