542 EEPOKT OF COMMISSIONER OP FISH AND FISHERIES. 



a Elongate oval, more attenuate in front, black, with slight olivaceous 

 tinge; surface densely, finely, and equally punctured. Head with a 

 sigmoid row of coarse punctures on each side, meeting at the vertex. 

 Antennae and palpi testaceous. Thorax with a small fovea on each side ? 

 near the anterior margin, behind and within the eyes, and an angulate 

 row of punctures on each side near the middle, and a few coarse punc- 

 tures very irregularly disposed. Elytra with four strice of moderate 

 punctures, the first two sutural and extending nearly from base to apex, 

 inclosing at base a short scutellar row ; the outer two rows subhumeral,, 

 obliterated at base, extending nearly to apex, and becoming confused, 

 extending toward the inner rows. Body beneath black, opaque, and 

 pubescent, abdomen with a row of brownish patches at the sides of 

 each segment. Legs pale testaceous, femora at base and tarsi black. 

 Length, .38 inch; (9.5 mm .) 



Eesembles lateralis in form, but more narrowed in front than behind. 

 The elytra are evenly punctured, and the body along the median line 

 moderately convex. It differs from all our species by the four distinct 

 striae of punctures on each elytron. The outer two correspond in posi- 

 tion with the eighth and ninth, and traces of a third, fourth, and fifth 

 are visible at base.'' — Horn.

"Head brownish testaceous, moderately shining, sparsely clothed with 

 yellowish hairs, front feebly concave ; parts of mouth and antennas tes- 

 taceous, the latter darker at tip. Thorax paler than the head, as broad 

 as long, disk depressed, sides strongly rounded in front, behind the 

 middle sinuate ; base truncate, feebly emarginate at middle, and but 

 slightly broader than half the width of thorax at middle; surface 

 sparsely punctured and pubescent. Elytra pale testaceous, sparsely 

 punctured and pubescent, short, sides strongly divergent behind ; body 

 apterous. Abdomen elongate oval, broader behind the middle, piceous, 

 shining, and very sparsely pubescent. Legs pale testaceous. Last 

 segment of abdomen $ slightly prolonged at middle and sinuate on each 

 side. Length, .08 inch, (2 mm .) 



The male resembles in its several characters P. Balticus Kraatz, of 

 Europe, but the median prolongation of the last abdominal segment is 

 broader. The penultimate segment is subcarinate along the median 

 line behiud. The mandibles in the present species are much more exsert 

 than in the species from California.
