ART. 4 BEETLES OF THE GENUS COCCINELLA DOBZHANSKY 15 



punctures becoming stronger toward the external margin of the ely- 

 tra. Elytra yellow or red with a common black subbasal fascia (spots 

 l + K+l), a very small spot near the external margin (2), which is 

 mostly absent in the American specimens (var, guinquenotaia Kirby), 

 a large transversely oval spot on the disk (3), and a subapical trans- 

 verse fascia (spots 4 + 5) . The subbasal fascia and spot 3 are reduced 

 in the western specimens to narrow black stripes (var. transversalis 

 Mulsant). Length of the body, 5.8-7.2 mm. 



Male genitalia (fig. 6). — Penis longer than the paramera, rather 

 wide, deeply emarginated in the distal half of its length, the distal 

 end extended into a tonguelike process. Basal plates wider than long. 



Female genitalia (fig. 24) . — Receptaculum seminis similar to that of 

 C. novemnotata Herbst, but shorter, wider, and with slightly thinner 

 walls. Infundibulum also similar to that of C. novemnotata, but rel- 

 atively longer and more slender. 



Casey (1899) insisted on calling the American representatives of 

 this species quinquenotata Kirby, and on restricting the name trans- 

 versoguttata Falderman to the Asiatic representatives. I see no suffi- 

 cient reason for such a separation, since the only difference between 

 the American and the Asiatic representatives of this species is the fre- 

 quent absence of spot 2 in the former. The absence of this spot is, 

 however, observed also in Asiatic specimens, though as an exception, 

 and its presence is sometimes observed in American individuals. The 

 genitaha are completely alike in the American and in the Asiatic 

 specimens (see Dobzhansky, 1926, fig. 1). Consequently, it seems 

 superfluous to preserve the name quinquenotata Kirby even as a sub- 

 specific name.
