ART. 4 BEETLES OF THE GENUS COCCINELLA DOBZHANSKY 21 



however, to the group of species headed by the palaearctic species C. 

 sejpteraj)unctata Linnaeus. Though these two sections of the genus are 

 related to each other, I can not agree with Leng, who places both 

 difficilis Crotch and suturalis Casey as varieties of nivicola Menetries. 

 Coccinella vandyTcei Nunenmacher is a synonym of difficilis Crotch.

COCCINELLA SUTURALIS Casey 



Coccinella suturalis Caset, 1899, p. 89. — Johnson 1910, p. 64. 



Coccinella monticola Mulsant var. suturalis Casey, Leng, 1903, p. 198; 1920, p. 216. 



Elongate-oval, less convex than any other American species of Coc- 

 cinella. Head and pronotum similar to C. difficilis Casey. Anterior 

 angles of the pronotal epipleura with quadrangular white marks in 

 females, and only narrowly white in males. Mesepimera white, met- 

 epimera black. Punctulation of the pronotum and of the elytra dense 

 and strong, becoming much stronger toward the external margin of 

 the elytra and toward the sides of the pronotum. Elytra orange, 

 with a large, obcordiform scutellar spot (}0, a rather broad black stripe 

 along the suture, an oblique black fascia on the disk (spots 2 + 3), and 

 a tranversal black spot in the posterior third of the length (spots 4 + 5) . 

 Length of the body, 5.5-5.8 mm. 



Male genitalia (fig. 8) . — Penis similar to that of C. difficilis Crotch, 

 but considerably longer than the paramera, the distal process much 

 longer and less pointed at the end. Basal plates wider than long. 

 Siphonal capsule not angulate. 



Female genitalia. — Unknown. 



Coccinella suturalis Casey is related to diflcilis Crotch, but differs 

 from it in the shape of the body, in the punctulation and the pattern 

 of the elytra, and in the structure of the genitalia.
