ART. 4 BEETLES OF THE GENUS COCCINELLA DOBZHANSKY 19 



COCCINELLA NIVICOLA Menetries subspecies ALUTACEA Casey 



Coccinella alutacea Casey, 1899, p. 89. 



Coccinella transversoguttata Falderman var. alutacea Casey, Lbng, 1903, p. 200. 

 Coccinnella monticola Mulsant var. alutacea Casey, Johnson, 1910, p. 63. — Leng, 

 1920, p. 216. 



Differs from the typical nivicola Menetries and from var. monticola 

 Mulsant by the more strongly alutaceous surface of the elytra; the 

 finer and sparser punctulation, and by the reduced pigmentation of 

 the elytra. The shape of the body is less convex in alutacea than in 

 monticola. The scutellar spot is rather small, the black fascia nar- 

 row, frequently disintegrating into a small round spot 2, and a large 

 transversally oval spot 3. The apico-marginal spot (4 + 5) small, 

 round or transversally oval. Spot 2, or spot 4 + 5, or both, may dis- 

 appear (var. biguttata Johnson). Metepimera and the posterior ends 

 of the metepisterna usually brown or yellow, though specimens hav- 

 ing black metepimera also occur. The genitalia of both sexes are iden- 

 tical with those of typical nivicola and of subspecies monticola. Leng 

 and Johnson were correct in not recognizing this variety as a separate 

 species.

Remarks. — Individuals from western Utah, Nevada, and California 

 are characterized by an extreme reduction of the pigmentation of 

 the elytra. Indeed, most of them have only spot 3 (var. biguttata 

 Johnson), or only spot 5. Besides this they are usually smaller, less
