than long; sides strongly arcuate and convergent posteriorly; disk mod- 

 erately convex. Elytra conjointly wider than long, much shorter than the 

 pronotum. Abdominal segments not decreasing in width posteriorly. Legs 

 slender. Length 2.8-3.8 mm. 



This species is common on the ocean beach at San Diego, 

 Cal. A figure of the anterior portion of the body is given 

 on the plate. The elytra are, in proportion to the length of 

 the pronotum, longer than in either of the others. 



P. califomica, n. sp. — Form slender; sides parallel; anterior portions of 

 the body dark blackish-piceous, elytra slightly paler, translucent, piceo-tes- 

 taceous, abdomen above and below black; antennae and legs testaceous, 

 translucent, the former very slightly darker toward tip; pubescence very fine, 

 short and sparse, recumbent; integuments very coarsely and evenly granu- 

 late, abdomen shining and minutely reticulate. Head wider than long, very 

 feebly and coarsely punctate; eyes large, finely granulate, rather prominent; 

 antennae slightly shorter than the head and pronotum together, very slightly 

 thicker toward tip, basal joint slender, not as long the next two together, 

 second slightly longer and more robust than the third, outer joints much 

 wider than long, last as long as wide. Prothorax widest slightly before the 

 middle where it is slightly wider than long and one-third wider than the 

 head; sides evenly and strongly arcuate; base slightly shorter than the apex, 

 two-thirds as wide as the disk, broadly arcuate; apex broadly emarginate; 

 basal angles obtuse and slightly rounded; disk moderately convex, finely, 

 feebly and rather sparsely punctate; having a very feebly impressed dorsal 

 line. Elytra at base slightly narrower than the pronotum; sides rather 

 strongly divergent posteriorly and rather strongly arcuate; together two- 

 thirds wider than long and about three-fourths as long as the pronotum; 

 apex transversely truncate, slightly sinuate in the middle; apical angles 

 acutely produced; disk depressed, impunctate, very slightly wider at apex 

 than the pronotum. Scutellum triangular, as wide as long, darker in color. 

 Abdominal segments long, equal in width to the fifth, slightly narrower than 

 the elytra; border strong, segments transversely impressed at base, de- 

 pressed, shining with an reneous lustre, finely, closely and asperately punc- 

 tate. Legs slender, moderate in length. Abdomen beneath tipped with a 

 paler reddish tint. Length 2.7-3.5 mm. 



California (San Francisco, 5.) 



The abdominal border is deeper and less depressed than 

 in opaca. The pubescence of the abdomen above and 

 beneath is longer and very much closer than upon the re- 

 mainder of the body. The species is very rare on the sea 

 beach near the Cliff House.
