larger than the Two -spotted, and ornamented with nine black: 

 spots. 



The Plain Lady-bird, C. 7nji?idn,^^y. (see fig. ii), is rather smaller- 

 than the others of its kind, of a light brick red, but with its elytra.

jj^Sb/' The Three-banded Coccinella, C. trifasciata, linn, is 



F^' 'iIK^ ^^ ^ ^^^ brick color, marked with two irregular black bands 

 J \Jpf V across the elytra, and a black spot near the posterior angle. 

 It is ot an intermediate size between its cousins, the Two-spotted Lady- 

 bird and the Fifteen-spotted Mysia. 



The Spotted Lady-bird, ^}!^/d7^(Z/'/'<!/^ macnlata, De Geer (see fig. 12) is 

 a small pinkish beetle, but occasionally of a pale red, with large _^5;,-^^ 

 black blotches twelve in number ; two of them on one elytron 

 are opposite to and touch two on the other. Mr. Riley says that 

 this insect commits great havoc upon the Chinch Bug. and upon 

 the eggs of the Colorado Potato Beetle. 



The Thirteen-dotted Lady-bird, U. ij-pnnctata, Linn, (see fig. 13) is 

 rather larger than the preceding : it has 

 thirteen black spots on a brick red

The Convergent Lady-bird, //. cou- 

 vei'gens, Guer. (see fig. 14) is of a deep orange red 

 color, marked with black and white. It has been of great use in checking 

 the ravages of that destructive pest, the Colorado Bug ; its larva is blue, 

 orange and black, and in its jnipa state it is of the exact color of the 

 larvae of the Colorado Beetle, for which it is often, doubtless, mistaken 

 and ruthlessly destroyed. 



The Parenthetical Lady-bird, // parenthesis, Say, is a small beetle of 

 a dull red color, and can be easily distinguished at a glance by the dark 

 marks, curved like the bands of a parenthesis ( ), one on the hinder 

 part of either wing cover ; there are two black spots on each elytra, 

 besides the parenthesis, one on the anterior part and the other on the 

 inner margin, touching the one on the other cover. 



The Fifteen-spotted Mysia, Mysia i ^-punctata, Oliv., is black on the 

 head and prothorax, with seven black spots on each of the brownish red 

 elytra, and another on the scutellum, according to Packard. But it 

 appears to vary much in its perfect form and in color from a very light
