64 FIELD AND FOREST. 



ranged in half screws, which give it the properties of a file ; the stride 

 are hiterrupted here and there by small spines of soft consistence, 

 which serve for the perception of tactile sensations. The orifice of 

 the canal through which the liquids ascend is situated on the lower sur- 

 face below the first screw-thread. Not content with examining Ophi- 

 deres fullonica, Linn., I investigated all the representatives of the ge- 

 nus, and found that O. materna. Linn., O. salaminia, Cram., O. ini- 

 perator, Boisd., as well as the other species, have a powerful trunk in 

 the form of a borer. The structure of the raaxilse, therefore, furnishes 

 a generic character of great value; moreover it establishes a closer rela- 

 tionship between the Lepidoptera, the Hemiptera and certain Diptera 

 in which the maxillae are destined to pierce tissues. The Australian 

 colonists dread O. fullonica on account of the mischief caused b}' it in 

 the orange plantations ; for the fruits which it pierces with holes quick- 

 ly spoil, and soon fall to the ground and rot, All the Lepidoptera of 

 the genus Ophideres being, as I have just shown, furnished with a ter- 

 ebrant trunk, it is incontestable that they have similar habits, and 

 that they will bore into oranges and other fruits. As they are very 

 widely diffused in tropical regions, they must justly be ranged among 

 injurious insects. 



Unfortunately their early stages are unknown, so that no really 

 practical remedy suggests itself to the mind; but their large size and 

 striking colors, allowing them to be recognized at the first glance, they 

 may killed without fear of reproach for commiting judicial error." —
