18 PROCEEDINGS OP THE NATIONAL MUSEUM vol. 80 



orange or yellow, alutaceous, punctation dense and strong, becom- 

 ing stronger toward the external margin, with a very large pyriform 

 scutellar spot (}0, an oblique transverse fascia not attaining the 

 suture or the external margin (spots 2 + 3), and with a large, trans- 

 versally oval spot in the apical third (spots 4 + 5). Length of the 

 body, 5.8-7 mm. 



Male genitalia (figs. 7, 18). — Penis considerably longer than the para- 

 mera, slightly wider at the middle of its length than at the base, rapidly 

 narrowing distally, the distal end extended into rather long fingerlike 

 process. Basal plates longer than wide. 



Female genitalia (fig. 25). — Receptaculum seminis short and wide, 

 with ringlike sculpture on its walls rather delicate. Infundibulum 

 short and thick, its posterior end with a funnel-shaped dilatation, the 

 diameter of which is nearly twice as much as the diameter of the 

 anterior dilatation of the infundibulum. Accessory plate absent. 



I find C. monticola Mulsant not specifically distinct from the Asiatic 

 species Coccinella nivicola Menetries, The typical nivicola (from 

 eastern Siberia) differs from monticola in having the anterior fascia 

 extended toward the humeral angles and in having a stronger punctu- 

 lation of the elytra. Both characters are, however, variable. Indi- 

 viduals of monticola from Canada and the Northern United States 

 have the elytral fascia very broad, and frequently extended toward 

 the humeral angles. On the other hand, individuals of nivicola from 

 southern Siberia, Mongolia, and Djungaria have the elytra! pattern 

 approaching that of monticola. Even more important is the fact that 

 the genitalia of nivicola (see Dobzhansky, 1926, fig. 6) are identical 

 with those of monticola. Thus, monticola must be considered a sub- 

 specific form of nivicola, equivalent to the subspecies alutacea Casey. 



Geographic distribution. — Localities as follows: 

 Quebec: Quebec, Hudson Bay (University of Minnesota collection). 

 New Hampshire: Mount Washington, Lancaster, Franconia. 

 Michigan: Whitefish Point. 

 Minnesota: Duluth, Itasca Park. 

 Montana: Glacier National Park (T. Ulke collector), Missoula (National 



Museum collection). 

 Utah: Brighton (National Museum collection). 

 Colorado: Rogers Pass (Bradley collector). 

 Florida: State record (Illinois State Natural History Survey collection; this 



record is very doubtful). 

 California: Lassen National Park (8,000-10,000 feet, Dobzhansky collector), 

 Tallac (A. Feneys collector). Fallen Leaf (California Academy of Sciences 

 collection), Eldorado County (Blaisdell collector), Mono (Blaisdell collector): 



Remarks. — The individuals from Montana, Colorado, and Utah 

 are intermediate between monticola and alutacea. Those from Cali- 

 fornia have the elytral pattern similar to that of monticola from New 

 England, but one individual has the anterior fascia connected with 

 ihe scutellar spot.
