Exhibits the aphis, puceron, or vine-fretter, and the Infe£ls which defiroy it. 



Fit^. I. reprefents the aphis of the rofe-tree without wings very much magnified, copied- 

 from M. Bonnet, with its antennae before, and its two horns behind, which are not half 

 the length of the antennse, are immoveable, and faid by Bonnet to be hollow canals from 

 which the fwcet juice called honey- dew is evacuated ; laftly, with the trunk under its 

 head in the pofitiort in which it penetrates the leaves. In fome the horns behind are want- 

 ing, and little knobs fupply their place, which- Reaumur thinks fupply the fame fweet 

 juice. That fome poffeffing wings, and others not, does not diftinguifh the fexes is agreed 

 by all obfervers.

 pended for fome time after it is otherwife born. 



Fig. 3. reprefents the aphidivorous larva, with an aphis in its mouth, and the chryfalis of 

 the fame infed, before it is transformed into the fly at fig. 4. All thefe were drawn from
