TIMES, PLACES, AND SEASONS FOR COLLECTING. 265 



yield a rich harvest, if properly examined, in May, 

 June, July, and August, hefore and after which pe- 

 riods the game is more scarce. The Oak generally 

 yields a rich spoil of this kind. Two or three large 

 sheets may be spread underneath while the branches 

 are beaten with long rods, and the result will be an 

 abundant harvest of several kinds of Lepidopterous 

 larvae, and probably some pretty Coleoptera. Many 

 rare kinds of larvae may be found on plants growing- 

 near the sea-shore, not to mention the splendid Cater- 

 pillars of the Spotted Hawk-niotk found on the sea 

 spurge on the coast of Devonshire. Mr. Douglas in- 

 forms us that in November, 1849, he found on the 

 Carline Thistle, near Folkestone, a number of larvae 

 then unknown to him, which in the following July pro- 

 duced the Moth since named Parasia Carlinella, a 

 species before entirely new to English collectors. 

 Many other species, doubtless, remain to be dis- 

 covered in a similar manner ; or, at all events, if 

 the perfect insect should be known, the collector 

 may be the means of settling the identity of the 

 larvae, which in many cases remain undescribed, even 

 those of comparatively common species. The Cater- 

 pillar of J?ieris Dapliclicce, the scarce Bath- white 

 Butterfly, must be sought near the shore, as the 

 perfect insect has never been taken far from the sea.
