The Cetonia-larva 



baeldae, which, thanks to the exceptional ar- 

 rangement of its nerve-centres, lends itself, 

 alone of all larvae, to the Wasp's successful 

 enterprises. In the presence of this under- 

 ground game, so greatly varied in size and 

 shape and yet so judiciously selected to fa- 

 cilitate paralysis, I do not hesitate to gene- 

 ralize and I accept, as the ration of the other 

 Scoliae, larvae of Lamellicorns whose species 

 will be determined by future observation. 

 Perhaps one of them will be found to give 

 chase to the terrible enemy of my crops, the 

 voracious White Worm, the grub of the 

 Cockchafer; perhaps the Hemorrhoidal 

 Scolia, rivalling in size the Garden Scolia 

 and like her, no doubt, requiring a copious 

 diet, will be entered in the insects' Who's 

 Who as the destroyer of the Pine-chafer, 

 that magnificent Beetle, flecked with white 

 upon a black op brown ground, who of an 

 evening, during the summer solstice, browses 

 on the foliage of the fir-trees. Though un- 

 able to speak with certainty or precision, I 

 am inclined to look upon these devourers of 

 Scarabaeus-grubs as valiant agricultural auxi- 

 liaries. 



The Cetonia-larva has figured hitherto 

 only in its quality of a paralysed victim. We 

 will now consider it in its normal «tate.
