THE CANADIAN ENTOMOLOGIST. 403 



C. Jo/insoni, n. sp. — Not very broadly oval, very convex, polished, 

 extremely minutely pimctulate ; head with the usual two large pile spots; 

 pronotum with a quadrate spot at the angles, with the lateral border black 

 for some distance anteriorly, the hypomera pale only at apex, the pale 

 area extending posteriorly near the edge to apical two-fifths; elytra with 

 the sutural edges finely blackish, a moderate rhomboidal scutellar spot, 

 and each with a circular subhumeral, a medial from inner fourth to the 

 median line, a very small submarginal at a third from the base and two 

 subapical spots, the outer of which is much the smaller but detached. 

 Length, 6.0 mm ; width, 4.7 mm. California (San Diego). 



This form, which I originally considered a spotted modification of 

 Californica, but which in reality is a very well-marked species of the 

 j-?iotata series, is dedicated with pleasure to Mr. Roswell H. Johnson, 

 who is now engaged upon a general biological study of colour variations 

 in the Coccinellidce. 



C. OregOfia, n. subsp. — Large in size, distinctly elongate-oval, yellow- 

 ish, polished, finely punctate ; head pale, the apical and basal margins 

 evenly, transversely black ; pronotum with a large quadrate anterior spot 

 at each side, the iwo united along the apical margin, the hypomera pale 

 in apical three-fifths; elytra with the sutural edges finely blackish, a small 

 subrhombiform scutellar dash, and each with the usual spots of p-?iotata, 

 though much reduced in size, especially the subhumeral, which is almost 

 obsolete. Length, 6.4 mm.; width, 4.9 mm. Oregon (southern). 



I have a good series of difficilis from Utah, collected by Wickham, 

 and its broadly rounded, subhemispherical form and markings evidently 

 ally it to the monticola group, in the vicinity o{ alutacea, and not, as indi- 

 cated by Crotch, to pei-plexa {-tri/asciata, Cr., nee L.). I have also 

 received the true migatoria^ from Santiago, Mexico, since my last revision 

 of the genus, and find that the subhumeral spot is well formed and 

 circuUr, the post-humeral also distinct and the scutellar blotch transversely 

 oval, indicating that it does not coalesce with the subhumeral, and the 

 elytral punctures are so nearly obsolete that they are only to be discerned 

 with difficulty. In 5-;/^/^/^ the subbasal fascia is seldom resolved into 

 three spots, and then in such ragged fashion as to show at once that they 

 have been derived by disintegration, and the elytral punctures are very 

 distinct. I think, therefore, that nugatoria ought to have the status of a 

 species.
