lady bird, Fig. 21, is of a deep orange color, with black and white 

 markings. There is a much larger species, the fifteen-spotted, 

 which presents many shades of color, varying from a light gray to 

 a deep brown. 



Fig. 22. Twice-Wounded Lady Bird. 



The twice- wounded lady bird, Chilocerus bivulnerus, is of a 

 deep, shining, black color, with a blood red spot on each wing 

 cover, and is about the size and shape of a smooth split pea. Its 

 natural size is indicated by the hair lines in Fig. 22. The larva 

 is a dark gray, prickly slug, repulsive in its appearance, but 

 extremely active and voracious in its habits. It may often be 

 found in the pupa state on the trunks of the trees infested with lice. 



In the beetle or perfect state, this insect is familiar to most of 

 our farmers, but it is to be feared that there are very many who 

 are not acquainted with its mission, and but very few who fully 

 realize the benefits derived from it. On the other hand, there are 

 but very few who are acquainted with it in the larva state. In- 

 stances are not rare where farmers, and even some who call them- 

 selves horticulturists, finding a long, dark colored, spotted grub on 

 their trees or plants, think it is a new foe, and commence with 

 energy the work of destruction, little knowing that every life he 

 takes is that of a friend, and gives immunity to hundreds of his 

 enemies. In the larva state all the species have a marked resem- 

 blance, being of an elongated, oval form, quite pointed behind, of 

 a dull color, with blue, yellow or black markings, and the soft, 

 slimy looking body covered with pointed tubercles, and six legs
