414 INSECTS INJURIOUS TO THE ORANGE. 



The Ashy-gray Lady-bird, 



Cycloneda abdominalis (Say). 



This is a small-sized lady-bird, which is often found in 

 abundance on infested orange-trees. Its larva also is very 

 common, and, when full grown, measures about four-tenths 

 of an inch long. It is black, variegated with orange, yellow, 

 and greenish white, and is shown, magnified, at Fig. 431, a. 



When about to transform to a pupa, the larva attaches the 

 end of its abdomen to a leaf, when shortly the skin, splitting 

 at the back of the head, gradually shrivels up towards the 

 posterior end, revealing the pupa, as shown in the figure at b. 

 This is of a whitish color, tinged in some parts with yellow- 

 ish, and ornamented with black spots. 



FIG. 431. 



The beetle is ashy gray, with seven black spots on the 

 thorax, and eight upon each wing-cover, arranged as shown 

 at c in Fig. 431, where the insect is represented magnified, 

 the smaller figure at the side indicating the natural size. 



The Blood-red Lady-bird. 



Cycloneda sanguinea (Linn.). 



The blood -red lady-bird is not so common as the species 

 last described, but is nevertheless very useful. The larva is 

 without spines, flattened in form, and ornamented with trans- 

 verse yellow bands and black spots ; it is most common in the 

 spring, when it is exceedingly voracious and active.
