ing only a narrow black bridge between them, Mesepimera and 

 metepimera, the posterior ends of the metepisterna, and, in the males, 

 a spot on the anterior coxae, white. White markings in the anterior 

 angles of the pronotum are extended toward the posterior angles and 

 toward the middle of the disk, and, in most cases, are united by a 

 narrow white stripe on the anterior margin of the pronotum. Ante- 

 rior angles of the pronotal epipleura broadly white. Pronotum and 

 the elytra alutaceous, rather densely and very finely punctulate, with 

 punctures somewhat stronger than in novemnotata Herbst. Elytra 

 yellow or orange with a large rhomboidal scutellar spot (K), a small 

 round spot (2), a large obliquo-transverse spot (3), and a transverse 

 spot in the apical third of then- length (4 + 5) , which sometimes is 

 separated into two spots (4 and 5). Length of the body, 6.2-7 mm. 



Male genitalia (figs. 3, 14). — Similar to those of C. novemnotata 

 Herbst, but penis shorter, its sides angulate, the proximal end 

 extended into a very broad, rhomboidal process. Basal plates wider 

 than long. Sipho very large, the siphonal capsule developed more 

 strongly than in any other species of Coccinella. 



Female genitalia. — Unknown. 



Geographic distribution. — Localities as follows: 



Montana: Helena (W. M. Mann, collector). 

 Wyoming: Yellowstone National Park (W. Robinson, collector). 

 Kansas: State record (National Museum collection). 

 Colorado: Denver, Garland (National Museum collection). 

 Washington: Wenatchee (E. J. Newcomer, collector). 



Remarks. — This species is rather closely related to C. novemnotata 

 Herbst because of the structure of the genitalia, the punctation of 

 the elytra, and the presence of the white spots on the anterior coxae 

 in the males. I can not agree, therefore, with the opinion of Mr. 

 Leng that prolongata Crotch is a variety of nivicola Menetries 

 {monticola Mulsant). I find no characters indicating such a rela- 

 tionship except the pattern of the elytra, which is indeed similar 

 to C. nivicola Menetries var. aluiacea Casey. On the other hand, 

 the genitalia of prolongata Crotch are quite suflSciently different 

 from those of novemnotata Herbst to consider them separate species. 

 The area of habitation of prolongata is completely included in that of 

 novemnotata. 



COCCINELLA PROLONGATA Crotch SEQUOIAE new subspecies 



Similar to Coccinella prolongata Crotch but with the frontal spots 

 smaller, with the quadrangular white spots in the anterior angles of 

 the pronotum not dilated, elytra much more strongly punctate, 

 intervals very finely alutaceous, reddish testaceous, elytral spots 

 3 + 2 + 4 + 5 + 3 + K+3 + 5 + 4 + 2 + 3 confluent. 



This race differs from the typical form in a rather large series of 

 characters. The white markings on the pronotum are not extended
