Genus COCCINELLA Linnaeus. 



The species of this genus recognized in the 

 United States are shown in fig. 47. Reference 

 to species outside of the United States is neces- 

 sarily omitted on account of the large size of the 

 genus. The species within the subgenera 

 are closely allied to each other, while 

 the subgenera are far less so. 



3056 a. Coccinella perplexa Mulsant. 



Distribution: North Europe, 

 Siberia, and North America. 



Our American 

 species corre- 

 spond closely to 

 the Coccinella tri- 

 fasciata of Eu- 

 rope and Siberia. 

 It differs in hav- 

 ing the black area 

 of the pronotum 

 sharply reentrant, 

 in most cases, at 

 either side of the 

 mesal portion (fig. 

 48). It is given 

 specific rank with some hesi- 

 tancy. A comparison of a large 

 series of each would be desirable. 



Var. eugenii Mulsant. Cephalic band broken 



'(fig. 49). 

 Var. == Coccinella trifasciata var. fennica 



Weise. Intermediate band broken. 

 Form A. Intermediate band only missing 



(fig. 49, d). 



Form B. Caudal band only missing (fig. 49, j). 

 Form C. Cephalic band broken and intermediate band 



only missing (fig. 49, d). 



Form D. Cephalic band broken and caudal band only 

 missing (fig. 49, w). 



Var. Juliana Mulsant. Intermediate and caudal bands 

 missing (fig. 49, /). A specimen from Cypress 

 Hills, Long Island, was probably transported there 

 upon plants. 



Form E. Intermediate and caudal bands missing, 

 cephalic broken (fig. 49, g.) 



Form F. Intermediate band only present. Oregon 



(fig. 49, o). 

 Var. subversa Leconte. Elytra without pigment. Pacific States (fig. 49, h). 



Form G. Black area of pronotum extends to the cephalic edge broadly as in Coc- 

 cinella monticola. Rare. One from Berkeley, California (fig. 49 rf).,
