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).,.
