SPOLIA ZEYLANICA. 



it seems to be decidedly polyphagous. The following description 

 was made from a full-grown larva found "at Madulsima on August 

 24, 1908 :— 



" It is about 7 mm. long, cylindrical, rather stout, the segmental 

 interstices well marked. Legs and prolegs long and slender ; pale 

 greenish-yellow. Head unicolorous, very pale, transparent, green i si i- 

 yellow ; mouth parts darker. Other segments pale greenish-yellow ; 

 a narrow darker green dorsal line ; each segment with a large 

 but ill-defined, pinkish-red, latero-dorsal spot, the series of these 

 spots forming an interrupted longitudinal line. Two conjoined 

 latero-dorsal tubercles emit a very long white hair directed upwards 

 and a shorter white palmate hair directed upwards and forwards ; 

 a supraspiracular tubercle emits a brown palmate hair directed 

 upwards and forwards ; two conjoined subspiracular tubercles emit 

 a short white hair directed forward and a long white hair directed 

 downwards ; there are also one or two latero- ventral tubercles 

 emitting white hairs. The whole surface of the segments is also 

 closely studded with short white clubbed secondary hairs." Figure 

 10 on Plate E was drawn from this living larva under the micros- 

 cope, and figure 8 on the same Plate gives a rather more detailed 

 view of one of the peculiar palmate hairs. 



The following description was made from the pupa produced by 

 the larva described above : — " The pupa is about 7 mm. long and 

 is attached to the under-surface of the midrib of a leaf of the food 

 plant. The appendage sheaths and anal portion are of a yellowish- 

 green colour, the remainder of a very pale pinkish-red. The dorsal 

 surface bears a system of highly specialized tubercles, the nature of 

 which will be best understood by a reference to the figure." (Plate 

 F., figure 11.)
