attraction by light was equivalent to that which is now well known in 

 many truly diurnal tiger beetles, for example lepida, spe7'ata and 

 lemniscata, and that it might have been found flying by daylight if the 

 proper spot had been hit upon. 



C. hcemorrhagtca''LQc. Dr. F. Blaisdell has found it at San Diego, 

 California, in April and May, on dark sand or clay soils along the bay 

 beach and on alkaline flats, running about between patches of maritime 

 vegetation. It is shy. I took it once at Provo City, Utah, running 

 along sandy roads in May. The form padjica Schaupp, I took on a 

 mud flat at Barstow, California, in August, while Dr. Blaisdell finds it 

 at Del Mar in the same state. He writes : "It occurs on sand, white 

 or dark, the latter preferably, both on the ocean beach and at Poway, 

 fourteen miles from the coast, on the course of a creek emptying into 

 the ocean. It is found alone, scattered and shy. The soil on the 

 beach is bare, that along the creek grassy and weedy. At night the 

 beetles repair to crevices in the cliffs which border the shore of the 

 ocean. Schaupp, in his synopsis, states thdit paci/ica 'has no markings 

 at all,' which is a mistake, as I have taken a great many specimens 

 with markings similar to hcBinorrhagica, but of the characteristic color 

 o'i pacific a.'" He further remarks concerning those California tiger 

 beetles on which he furnished notes, " All are abundant in their season 

 except hoemorrhagica, which has become quite rare about San Diego 

 Bay beaches where they were common before the advances of civili- 

 zation." 



C. rufiventris Dej. This species is said to be abundant on the hills 

 in Kentucky, opposite Cincinnati. The variety cumatilis Lee, was 

 found by Mr. Soltau on muddy places in the woods by Oak Grove, 

 Mobile, Alabama, in company with the type. The form i6-pn>icta/a 

 Klug, I found in abundance on the shores of the Rio Grande at Albu- 

 querque, New Mexico, flying about muddy flats. A single specimen 

 was also taken by the margin of a small pond at Luna, twenty- two 

 miles farther west. A variety of this species, apparently not described, 

 has been taken in the Canon of the Colorado River. I propose for it 

 the name arizonce, with the following characteristics: Form of i6- 

 piatctata, reddish bronze above, with greenish reflections which are 

 more pronounced on the head. Elytra with complete humeral lunule, 

 median band not or very slightly extended along the margin, obliquely 

 bent, not much narrowed at any part. A small post-median lateral 

 dot is present. The apical lunule is complete, but there is a tendency.
