CROTONS AFFECTED BY SCALE INSECTS. 



Our Grofcons are generally attacked by a species of scale 

 insect, Ortliesia, which very soon ruin them, but there is a 

 natural enemy, the Aphis lion, frequently following them. 

 This Aphis lion (fig. 2 a.) is a deadly enemy of the scale insect as 

 its eggs (fig. 2 6.) are laid in their immediate vicinity. These

esgs are ver}' much like the pistils of flowers, and arc deposited on 

 the leaves. It is popularly known as the golden eyed lace wing 

 fly, and belongs to the neuropteroiis genus chrysopa. 



There is another enemy, the '" Brachyacanthara Ursina" 

 (fig. 2c.), a minute rounded beetle, which, when pursued, 

 affects death.

A BULLET EXCAVATED BY A LARVA. 



We reproduce, from " Insect life," the figure of a bullet 

 which has been excavated by the larva of an insect which usually 

 bores Avood. This bullet must have 

 been fired into an oak tree, probably 

 during the Avar of Secession. When 

 this tree wj s felled it Avas found that 

 the larva of an Orthosoiia had pene- 

 trated it. This larva had evidently 

 commenced its attack in the conca\'e 

 extremity of the bullet, had gone 

 through tAvo-thirds of its length and escaped sidcAvays. 



This specimeii was found by Dr. Eversfield in Maryland.
