SOME COLEOPTERA OF THE BEACH 

 AT LAGUNA 



WITH DESCRIPTIONS OF NEW SPECIES BY 

 DR. M. BERNHAUER 



C. 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, Cercyou, and AcrittiH. Common on the sand of the 

 upper beach and driven out in considerable numbers by unusually 

 high tides occurred Dyschirins Hiai-hutx, P/mtoin/ilota opaca, Einphy- 

 iixtcs fucicola and Phycocoetes tcxtm-nix. The Dyscliiriuv, Pontn- 

 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. 



Tiie vegetation of the upper beach included the usual array of 

 maritime plants like SaJicnn/in, Hrl'mlni/iiuni, Atriplex, Fratikcina, 

 etc., and at the mouth of a small stream, Cypcrus, Salix, Typlia, etc. 

 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 Ei/flalus found commonly 

 on Cypcrus, and by various new Staphylinida?. 



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 Staphylinidae, a task for which he 

 is always very willing. 



CARABIDAE 



Dyschirius marinus Lee. 

 Common on open sand areas of the upper beach. 



HYDROPHILIDAE 



Cercyon fimbriatum Mann. 

 Occasional in masses of rotting kelp. 



STAPHYLINIDAE 

 Pontomalota bakeri Ilernhaner nov. sp. 



" Rufotestacea, opaca, abdomine ad apicem minus opaco, segmento 

 sexto parum obscuriore, thorace parum transverse, angulis posticis 

 subrotundatis; abdomine autice opaco-reticulato, postice subtiliter
