CYCLONEDA.

Genus CYCLONEDA Crotch. 



The color pattern and its lines of variation in this genus are markedly 

 different from Coccinella, of which Leng makes it a subgenus. The form, 

 agility, and the difference of the food of the larvae (Johnson, 1907) sup- 

 port the generic distinction. The sexual difference alleged to exist in the 

 pronotal pattern, though noticeable, is much less than indicated by Mulsant 

 and Dimmock. 



3064. Cycloneda sanguinea Linnaeus. 



Distribution: Cuba, Bahamas, Florida to California. 



Var. immaciilata Fabricius. With pale spots on pronotum inclosed. Florida to Louisiana- 



The sexual differences in the median emargination of the black pronotal 

 area is either absent or slight.

3064 a. Cycloneda munda Say. 



Distribution: Northeastern and North Central States. 



The males have a greater amount of pigment laterally on the pronotum, 

 but the median emargination of the black pattern is much deeper (figs. 63 

 and 64). This species, closely allied to the preceding, is recognized 

 because of Dimmock's statement that the larvae differ specifically. 



Var. polita Casey. 



Having the scarlet color of C. sangmnea (figs. 65 and 66) . It will probably prove to 

 be a variety, because in its range, the northwestern States, yellowish indi- 

 viduals are occasionally met with. It is possible, however, that these speci- 

 mens are caused by different degrees of fading.
