the pigment is often brownish instead of black, and the outlines of 

 the spots are frequently diffuse and indistinct. Length of the body, 

 4.3-5 mm. 



According to Casey (1899, 1908) this is a species separate from 

 trifasciafa {perplexa). The opinion of Leng and Johnson seems to be, 

 however, better founded. An investigation of the genitalia of a large 

 series of specimens of C. subversa from Oregon failed to reveal any 

 difference between it and the typical C. trifasciata from the Eastern 

 States, except, perhaps, an insignificant difference in the absolute 

 size. Thus, C. subversa may be classified as a good example of a 

 subspecific form. 



Geographic distribution. Localities as follows: 



British Columbia: Agassiz, Vancouver, Wellington, Victoria. 



Washington: Orcas Island, Mount Vernon, Everett, Port Angeles, Seattle, 

 Tacoma, Puyallup, North Bend, Easton, Paradise Park (Mount Rainier), 

 Longmire (Mount Rainier), Tenino, Oakville, Vancouver. 



Oregon: Astoria, Agate Beach, Neskowin, Olney, Portland, Hillsboro, Forest 

 Grove, Cannon Beach, Tillamook. McMinnville, Siuslaw National Forest, 

 Wilsonville, Corvallis, Waldport, North Bend, Josephine County. 



California: Scotia, Fortuna, Orick, Klamath, Hydesville, Sonoma County, 

 Berkeley, Oakland. 



Remarks. — As shown by the list of localities, the subspecies is 

 abundant in Washington and Oregon, in the whole region between 

 the Cascade Range and the Pacific Ocean. Its distribution extends 

 to British Columbia, where it overlaps the distribution of the typi- 

 cal C. trifasciata. In the south the distribution of subversa overlaps 

 that of the subspecies eugenii Mulsant and Juliana Mulsant. It 

 must be noted, however, that the individuals of subversa from Cali- 

 fornia have the form of the body and the punctation of the elytra 

 more similar to that of Juliana than to that of subversa from Oregon 

 and Washington. The parts of Oregon and Washington lying east 

 of the Cascade Range are apparently inhabited by typical trifasciata. 

 Thus the Cascade Range appears to be the line dividing the two 

 subspecies.

This is a geographical race intermediate between the subspecies 

 subversa LeConte and the subspecies Juliana Mulsant. The size and 

 the punctation of the elytra are as in subversa. The pattern of the 

 elytra may consist of the three transverse fasciae similar to those of 

 the typical trifasciata but much narrower and showing a clear tend- 

 ency to disintegrate into separate spots. More frequently the inter- 

 mediate fascia is broken into a small round spot 2 and an oblong,
