 found no variation. It foods on (iardonia. Butler's fii];uve (T. 

 Z. Soc, 1875, t. 90, f. ()) of }iiii-. lldis. so precisely agrees with 

 our larva that a description of it here is rendered unnecessary. 

 Our pupa is rather darker in colour than in his figure.

I 

 Butler's figure of the larva of this species presents such 



an extraordinary diversity of appearance from that of the pre- 

 ceding species as to raise doubts in my mind of its correct 

 application to Hylas, considering how nearly allied the two 

 insects are. Horsfield and Moore's figure is not from life, 

 which will account for its shortcomings. The copy of ]\Ioore's 

 Lep. of Ceylon to which I have referred, is, unfortunately for 

 me, deficient of the part containing this genus,
