marked with thirteen black dots. The wing-cases of the Ten- 

 spotted Lady-bird (Fig. 327) are of a pinkish color, and are 

 marked with ten black dots. The Convergent Lady-bird (Fig. 

 328, c) has the wing-cases yellowish-brown and marked with 

 twelve black dots. The Nine-spotted Lady-bird (Fig. 329) 

 has the wing-cases of a yellowish-brown color, marked with 

 nine black dots. The Icy Lady-bird (Fig. 330) has the wing- 

 cases of an orange-yellow color, marked with from four to six 

 black dots. The Trim Lady-bird (Fig. 239) has the wing- 

 cases of an orange-yellow or orange-red color; they are un- 

 marked. The California Lady-bird (Fig. 289) differs from the 

 Trim Lady-bird by having a white spot on each of the front 

 corners of the thorax the Trim Lady-bird having the thorax 

 margined, in front and at the sides, with yellow. The Twice- 

 stabbed Lady-bird (Fig. 331) is entirely black, with the exep- 

 tion of a deep red spot on each wing-case. The Painted Lady- 

 bird (Fig. 332, c) is of a pale yellow color, with a black stripe 

 on each wing-case, the two stripes being connected by two 

 black bands.

' The Mantis (Fig. 142) also feeds upon other insects; the 

 female deposits her eggs in large masses (Fig. 308), and the 

 young closely resemble the parents, with the exception of 

 their being destitute of wings; they are not quiescent in the 

 pupa state, but continue active throughout their life. 



The Soldier-bugs (Figs. 114 and 154) feed upon caterpillars 

 and other insects by impaling them upon their beaks and 

 then leisurely extracting their juices. These bugs do not pass 

 through a quiet pupa state, but continue active from the time 

 they issue from the eggs until they die. They do not confine 

 their attacks to insects, but occasionally feed also upon the 

 juices of plants.
