nia;ht feeders, as I have often seen californicus wandering from 

 its haunts after sundown, as if in search of food. During the 

 day they hide under small pieces of wood and branches of trees, 

 rarely under large logs, and for three years in succession I ob- 

 tained a large number of specimens of the present species by 

 throwing some finely cut pieces of meat around the places in 

 which I knew they were to be found. The lid of a box made 

 an excellent trap, and one day I obtained, in a spot only about 

 ten feet square, no less than twenty-six specimens. An English 

 collector took over one hundred and fifty californicus at the 

 Presidio, San Francisco, by digging in a sand bank, after having 

 well baited the neighborhood, for several days, with finely 

 chopped meat. I am not aware that this species has been found 

 farther south than Gilroy, Santa Clara Co., or farther to the 

 north of the State then Mendocino. It is certainly the most 

 common of the group. 



0. Audouinii. I have seen no specimens of this insect taken 

 farther south than the upper portion of the Sierra Nevada, in 

 Plumas Co. It is far from rare in Oregon, and is occasionally 

 found in some numbers along the rocky shores of the Columbia 

 River, particularly about the Dallas. It is also frequent in 

 Washington Territory and Vancouver Island, specimens having 

 been found in the latter locality both by the late Mr. Crotch 

 and myself. 



0. Dejeanii. Very common in some portions of Vancou- 

 ver Island, especially about Sannich and Gold Stream. This is 

 the largest and decidedly the handsomest species of the group. 



0. laevis. In a letter to me from Dr. Horn, dated July 1, 

 1870, the following passage occurs : " My 'laevis ' was found in 

 the foot hills east of Visalia, I think. It would do no harm to 

 explore in the neighborhood of Half Moon Bay and Monterey, 

 as I have an indistinct suspicion that insects from the two local- 

 ities are mixed in my hands, accidentally. " I regret that I am 

 able to add no more information with reference to this unique 

 species, which Dr. Horn informs me is remarkably distinct from 

 any other form known to him. 



0. submetallieus. Soon after my arrival in California, I 

 pointed out to my friend, Mr. James Behrens, of this city, a
