gabbii is infrequent on the mud of salt marshes at 

 San Diego and Wilmington in August and September, 

 and is rarely taken on the ocean beach; Long Beach, 

 August (Daggett): senilis, near San Diego, in damp 

 places away from the ocean (Dunn): vulgaris and its 

 variety obliquata, at San Luis Eey (Dunn); the latter also 

 on the borders of the Big Laguna, Temecula Valley 

 (Blaisdell): vibex, on the ocean beach at Oceanside 

 (Blaisdell) and near San Bernardino (Wright): 18- 

 guttata and varieties, widely diffused along fresh water, 

 Feb. to Oct. The most common form is that which 

 Le Conte called oregona; these graduate into guttifera 

 as Arizona is approached; typical 12-guttata is seldom 

 taken. The various forms are so perfectly connected 

 that it seems scarcely worth while to continue the 

 three names. The impression is quite general among 

 coleopterists that l-guttata is not a variety of repanda, 

 and it seems quite certain to me that it must be given 

 full specific standing. 



C. pusilla occurs in Owen's Valley: tenuisignata, Palm 

 Springs and Colorado River: sperata, plentiful along the 

 Colorado at Yuma in July: lemniscata, between San 

 Diego and the Mexican boundary (fide Fuchs): prcetex- 

 tata, San Diego County (Fuchs). C. hcemorrhagica and 

 C. paciftca are found along fresh-water streams at San 

 Diego and San Bernardino; the former occurs on the 

 sandy margins of salt flats back of the ocean beach at 

 Santa Barbara in August and September, also at Yuma 

 (Horn), while the latter has been taken by several col- 

 lectors on the ocean front at Del Mar. C. sommeri is 

 reported from the vicinity of San Diego. 



The following species or varieties are recorded from 

 the more northern portions of the State: perviridis, 

 graminea, 10-notata, fulgida, cinctipennis , imperfecta, 

 lunalonga, depressula, lauta, and plutonica.
