COCCINELLA 20-MACULATA. ( Plat© xi, fig. 4.) 



Color pale honey-yellow, marked with twenty black spots somewhat confluent on the 

 middle of the elytra. Insect quite small. 

 In some of the plates the green coloring is too deep. There is a variable state of the 

 ground color : sometimes it is entirely pale honey -yellow ; in other instances, there is a 

 grayish green tinge. 



COCCINELLA NOVEMNOTATA. ( Plate xi, fig. 6.) 



Color luteous and reddish, marked with nine black spots ; one common to each elytrum, 

 situated near the base. Thorax bLick, margined in front with pale honey-yellow : the 

 black portion extends in front towards the head : body blaclf. The color of the elytra 

 is somewhat variable, yellow and reddish predominating each in different individuals. 



COCCINELLA IMMACULATA, ( Plate Xi, fig. 9.) 



Color luteous : thorax black, margined with pale honey-yellow or whitisli : elytra im- 

 maculate : body black. The flank of the thorax is quadridentate. 

 This insect does not agree with Mr. Say's description in every particular, still it is not 

 so different as to preclude the idea that it is a variety. 



COCCINELLA EIMACULATA. ( Plate xi, figS. 10, 11.) 



Color ferruginous, verging into luteous. Thorax varied with black and white ; the white 

 dilated margins being marked with a black dot, the black arranged in the form of 

 two decussating wide lines. Head marked with a central black line, which divaricates 

 posteriorly, or sends off branches to the eyes. Elytra marked usually with a single 

 black dot : body black beneath. 



COCCINELLA TRIOCULATA. 



The black spot upon the elytra is larger than in the preceding species, and the dilated 

 Avhite margins of the thorax are immaculate : the color of the insect is paler. The abdo- 

 men is black, bordered with rufous. 



COCCINELLA DU0DEX;iMN0TATA. 



Body black : head black and quadridentate in front, margined with luteous : thorax
