funnel-shaped dilatation of the infundibulum. Some species have an 

 accessory plate (Verhoeff' s Anhangsplatte, loc cit.) attached to the 

 posterior end of the infundibulum (a/p, fig. 22). 



COCCINELLA NOVEMNOTATA Herbst 



Coccinella novemnotata Herbst, Natursystem der Kafer, vol. 5, p. 269, 1793. — 

 Casey, 1899, p. 88.— Leng, 1903, p. 198; 1920, p. 216.— Johnson, 1910, pp. 

 59-60. 



Body subhemispherical. Head with a broad, undulate, yellowish- 

 white band across the front, and with yellow anterior margin of the 

 clypeus. Pronotum and pronotal epipleura with white subquadrate 

 marks in the anterior angles, anterior margin of the pronotum more 

 or less broadly white. Mesepimera and metepimera, the posterior 

 ends of the metepisterna, and in males a spot on the anterior 

 coxae and a stripe on the anterior femora, yellowish white. Head, 

 pronotum, and elytra alutaceous, obscurely punctulate with the punc- 

 tures somewhat stronger near the external margin of the elytra. 

 Elytra yellow or orange, with nine black spots (K, 1, 2, 3, 4). The 

 spot K moderate in size, triangular or rhomboidal, spots 1 and 2 small 

 and usually rounded, spots 3 and 4 large in size and transversely 

 elliptical in shape. The spots may fuse together or may be connected 

 by rather slender black lines. The following patterns have been 

 described: 1+2 (conjuncta Fitch), 3 + 5, K + 3, 2 + 1 + 3, 2 + 1 + 3 + 5 

 (confluenta Fitch). Length of body, 5.3-7 mm. 



Male genitalia (figs. 2, 13). — Penis rather long and narrow, its 

 proximal end extended in a triangular process. Paramera much 

 shorter than penis. Basal plates broader than long. Sipho rather 

 long and slender. 



Female genitalia (fig. 21). — Cornu broad, ramus very small, nodu- 

 lus conic in shape and thick-walled. Infundibulum short and thick, 

 its posterior end dilated and surrounded by a ringlike furrow. 



This purely American species seems to be related to the palaearctic 

 species Coccinella divaricata Olivier ( = distincta Redtenbacher) . The 

 points of similarity are the sculpture of the elytra, the shape of the 

 elytral spots, and the shape of the sipho and the infundibulum. The 

 form of the penis is, however, very different in these two species.
