170 first Annual Report 
SOME COLEOPTERA OF THE BEACH 
AT LAGUNA 
WITH DESCRIPTIONS OF NEW SPECIES BY 
DR. M. BERNHAUER 
Cc. F. BAKER 
No thorough collecting of Coleoptera was done at Laguna during 
the first year. However, in all our work along the beach and near 
the beach, beetles were collected wherever possible. Masses of de- 
caying kelp on the upper beach commonly swarmed with myriads 
of Staphylinidae, Cercyon, and Acritus. Common on the sand of the 
upper beach and driven out in considerable numbers by unusually 
high tides occurred Dyschirius marinus, Pontomalota opaca, Emphy- 
astes fucicola and Phycocoetes testaceus. The Dyschirius, Ponto- 
malota and Phycocoetes are remarkably protected on the sand, by 
their color. All four of these beetles appeared to be much more ac- 
tive in the late afternoon. 
The vegetation of the upper beach included the usual array of 
maritime plants like Salicornia, Heliotropium, Atriplex, Frankenia, 
ete., and at the mouth of a small stream, Cyperus, Salix, Typha, ete. 
A few beetles were also taken among these latter plants. The whole 
locality would doubtless yield rich returns by careful collecting, as 
is evidenced by the new Lappus, the new Endalus found commonly 
on Cyperus, and by various new Staphylinide. 
The determinations of species have mostly been made by Prof. H. 
C. Fall, to whom we are much indebted for this and other favors. 
Dr. Bernhauer has worked up the Staphylinide, a task for which he 
is always very willing.
