26 PEOCiEEDINGS OF THE NATIONAL MUSEUM vol.80 



Remarks. — This subspecies is very common in the San Francisco 

 region. To the north it gives numerous intergradations connecting 

 it with the subspecies eugenii Mulsant (see above). 



COCCINELLA HIEROGLYPHICA Linnaeus subspecies TRICUSPIS Kirby 



Coccinella tricuspis Kirby, Richardson's Fauna Boreali-Americana, p. 231, 

 1837.— Casey, 1899, p. 90.— Leng, 1903, p. 201; 1920, p. 216.— Johnson, 

 1910, p. 59. 



Body oval, more elongate than in other species of the genus Cocci- 

 nella, strongly convex. Head with white elongate spots near the eyes, 

 pronotum with quadrangular white marks in the anterior angles, the 

 anterior margin of the pronotum usually white, pronotal epipleura 

 with white quadrangular marks in the anterior angles. Mesepimera 

 and metepimera black, mesepimera brownish only in fresh specimens. 

 Pronotum densely and finely, elytra densely and strongly punctu- 

 late, elytra orange, with a common undulate subbasal fascia (spots 

 1+2 + 3 + ^ + 3 + 2 + 1), and with another transverse black fascia in 

 the posterior half of their length (spots 4 + 5), not continuous across 

 the suture. Length of the body, 3.7-4.3 mm. 



Male genitalia (figs. 11, 17). — Penis short, sugar-loaf shaped, with- 

 out processes or emarginations. Paramera short and thick. Basal 

 plates wider than long. Sipho short and thick, siphonal capsule 

 relatively very large. 



Female genitalia (fig. 28). — Receptaculum seminis slender, cornu 

 pointed at the end, ramus strongly developed. Infundibulum not 

 dilatated at its posterior end. 



I have shown (Dobzhansky, 1926) that the Siberian Coccinella tri- 

 cuspis Kirby subsp. mannerheimi Mulsant is not specifically different 

 from the European Coccinella hieroglyphica Linnaeus. This conclusion 

 may be extended also to the American tricuspis. The genitalia of C. 

 tricuspis Kirby (figs. 11, 17, 28) are completely like those of C. hiero- 

 glyphica (see Dobzhansky, 1926, fig. 4), and the external differences 

 between these forms, involving the color pattern and the shape of the 

 body, are by no means more extreme than those that are to be 

 expected between geographic races. Thus, the species C. hieroglyphica 

 inhabits the entire north of the holarctic region. The subspecies C. 

 hieroglyphica lives in Europe and in western Siberia ; C. mannerheimi 

 occupies eastern Siberia; C. tricuspis occurs in Canada and north- 

 ern United States; and C. humholdtiensis Nunenmacher inhabits 

 the Pacific coast area of North America.
