that the type specimen is labelled '' weranga " by Colonel Lang him- 

 self, and "is so quoted by him in vol. v, p. 35, of this Magazine, and 

 also by Mr. Moore at p. 266, n. 14, of the Proc. Zool. Soc. of London 

 for 1874, and elsewhere, and that we adhered to this form by Colonel 

 Lang's advice. 



I propose to comment on Mr. Butler's remarks on seasonal varia- 

 tion at a future date ; the remarks in his concluding paragraph 

 scarcely need notice from me. 



In conclusion, I would remark that more confusion in Indian 

 entomology has been caused by the publication of erroneous localities 

 without due investigation bv men whose names carry weight among 

 entomologists throughout the world, than by any other form of care- 

 lessness ; the localities are accepted by entomologists of other countries 

 who have no means of checking them, and not only are the true facts 

 obscured, but the false theories based on the blunders obtain a wide 

 circulation.

 of Alva, now of TilUcoultry. sent me a few eggs of this spaces^ Tbey 

 hatched out directly, and I at once placed them on a potted plant 

 of Yarrow. Unfortunately, the plant died, and I could find no 

 trace of the larv^ ; but, on writing Mr. Hinchcliffe of the misfortune, 

 this summer he very kindly made a search for the larvae, was at once 

 successful in finding them, and I had the pleasure of recen.ng a 

 supply from him on the 25th of June. They were m three stag s o 

 growth, though most were in the middle stage, or apparently about 



half grown. , . ^i. u 



They were of the usual form of larva, of this genus though 

 perhaps a little more slender than some species; body cyhndnca 

 rtoute'st in the middle, tapering towards the -— - W sm^ 

 and polished, considerably narrower than the second segment, seg 

 mental divisions well defined, the skin rather glossy. 



When about a quarter of an inch long, the ground colour .s pale
