one occasion a Bembidium littoraie carrying off a Dyschirius and a 

 Bledius, but did not succeed in finding out whether the Carabidse 

 had hold of the StaphyHnid or whether the Bledius had been seized 

 by the Dvschirius which in its turn had been attacked by the 

 Bembidium. I think the former alternative the more likely, as the 

 soft tissues of Bledius render it especially liable to the attacks of 

 stronger beetles, and in some spots, where it occurred in thous- 

 ands, the Dyschirius might be seen preying on it extensively. 



Where the beach was simply moist rather than wet, one 

 might get nice series of Phycoccetes testaceus under logs, in com- 

 pany with Elassoptes marinus. Both of these weevils are commonly 

 lound in colonies where they occur at all, the former, however, 

 being perhaps more partial to the shelter of bunches of cast-up 

 seaweed. These masses of algae also served as refuge for num- 

 bers of Cercyon fimbriaUmi, Cajius cauescens and Saprinus bigem- 

 meus. Back in the dry sand dunes, one might sit and scoop out 

 the side of a hillock, and, as the grains sifted down, out would 

 tall the Tenebrionidte that frequent them— the common forms 

 being Coehis ciliatiis, Plmlergia globosa and a species of Eleodes. 

 Sinodendron rugosiim and Ceruchiis striatus were dug from beneath 



half-buried logs. 



When the wind is in the right quarter, the collector may 

 always find some good things cast up by the waves ; but, as these 

 are usually species of at least fairly strong flight, I was surprised 

 to find drowned specimens of Otnus dejeanii and O. audouinii at 

 the water's edge. A number of Buprestis Langii were thrown 

 ashore, but one had to get them quickly if it were intended to 

 make use of them for the cabinet, as the bodies were immediately 

 attacked by small crustaceans and soon reduced to mere shells. 

 Leptura tibialis and L. matthewsii were occasionally noticed flying 

 over the beaches, but 1 could not ascertain whence they came. 

 Cicimlela bellissima was quite abundant, chiefly on the very fine 

 dry drifted sand close to the base of the bluffs, and. being only 

 moderately shy, was readily captured by working up from lee- 

 ward. I find a pair of Copidita quadrimaculata among my collec- 

 tions from this vicinity, but there seems to be no record in my 

 notes as to the circumstance of capture. However, I have found 

 the same insect in great numbers at San Francisco, under pieces
