Cane Fly of Grenada. : , 407 



trite. It is one of the most beautiful and remarkable genera 

 among the sedentary Annelides ; but the species now described 

 differs from the typical species, in having more than two ten- 

 tacular filaments at the mouth ; so that the generic character 

 of Cuvier and Lamarck will require some modification in 

 order to the reception of it.

For these last six months [back from March 13. 1833] 

 this island has been infested with a species of insect that 

 threatens not only great injury to the present crop of sugar 

 cane, but also to render the labours of the planter entirely 

 abortive for the next crop. The A N phis, puceron, vine- 

 fretter, blight, or cane fly, as the insect is here termed by the 

 planters, has long afforded an interesting study to the na- 

 turalist, and been a pest to the husbandman and gardener, 

 and is too well known to require particular description. I 

 am not aware that any species of insect hitherto noticed 

 has been found so formidable, either in number or destruc- 

 tive qualities, as the cane fly, which is now propagating, and 

 so rapidly overrunning the sugar plantations in this colony. 

 I therefore hope the following particulars respecting it will 

 not be altogether uninteresting to your readers, and that 

 these particulars will draw forth some useful observations 

 from those who may have had opportunities of witnessing the 

 habits and ravages of this tiny destroyer of the cane, and 

 who may, consequently, be able to thfOw some light on the 

 most effectual method of extirpating it. The insect, formed 

 with a snout and beak ending in a bristle, no doubt for the 

 double purpose of depositing its eggs and extracting its 

 food, attacks the cane in all the stages of its growth; but is 

 more particularly injurious to plants or ratoons when 'they 

 are young and tender. The under surface of the leaf, and 

 towards the midrib'; or the course of the larger sap-vessels, is 

 selected by the insect for the scene of its operations. There 

 it makes art oblique puncture, resembling that which would 

 result from a lancet introduced in the same direction. Into
