From the ANNALS AND MAGAZINE OF NATURAL HISTORY for 

 January 1891. 





A few Remarks on Prof. Packard's Papers entitled u Life- 

 History of Drepana arcuata " and u Hints on the Evo- 

 lution of the Bristles , Spines, and Tubercles of certain 

 Caterpillars " (Proc. Boston Soc. Nat. Hist. vol. xxiv. 

 pp. 482-559). By A. G. BUTLER, F.L.S., F.Z.S., &c. 



THE above-mentioned very suggestive papers, for a copy of 

 which 1 am indebted to their indefatigable author, constitute 

 one continuous article, containing much valuable information 

 ligently brought into a small compass.
