base. Elytra moderately transverse, slightly longer and much wider than the 

 prothorax, parallel ; humeri distinctly exposed at base ; disk flat, deflexed 

 at apex except laterally. Abdomen slightly narrower than the elytra, as long 

 as the anterior part of the body, parallel and straight at the sides ; border 

 strong ; segments subequal. Length 3.6-4.0 mm. ; width 0.9-1.1 mm. 



California (San Diego and San Francisco). 



Easily distinguishable from pacifica hj the narrow, more parallel 

 form and more conspicuous pubescence. Moderately abundant. 



It at first seemed probable that this species might be the same as 

 Homalota litoralis of Maklin, since the elytra are frequently rufous 

 with the base and external sides black, this being the described 

 coloration of litoralis; but the phrases " thorace .... posterius 

 ante basin latissime transversim impresso, confertim subtilissime 

 punctulato" do not find the remotest correspondence, there being 

 no trace of a transverse subbasal impression ; the width, also, 

 ^ line — about | mm. — is not sufficient for areno^ria. 



P. pacifica n. sp. — Parallel, moderately depressed, black, the legs rufo- 

 piceous ; antennse picescent toward base ; elytra, except laterally, feebly 

 rufo-piceous ; sculpture and punctuation as in arenaria, the pubescence much 

 sparser and less conspicuous. Head much wider than long, scarcely more 

 than three-fourths as wide as the prothorax ; eyes at rather more than their 

 own length from the base; antennse strongly incrassate, the outer joints fully 

 twice as wide as long, one-half longer than the head, shorter and thicker than 

 in arenaria, the second joint distinctly shorter than the third. Prothorax trans- 

 verse, nearly one-half wider than long ; sides parallel, evenly, strongly arcuate ; 

 apex broadly, strongly arcuate ; apical angles strongly deflexed, very broadly 

 arcuate ; basal extremely obtuse and almost completely obliterated ; disk very 

 feebly flattened toward the median line from base to apex. Elytra transverse, 

 only slightly wider and longer than the prothorax ; sides subparallel, straight ; 

 humeri strongly rounded to the prothorax ; disk flat, feebly deflexed at apex 

 in the middle. Abdomen, when contracted, distinctly shorter than the anterior 

 parts combined, nearly as wide as the elytra ; sides parallel and straight ; 

 border strong, rather deep ; first three segments impressed at base ; fifth longer 

 than the fourth. Length (contracted) 3.4 mm. ; width 1.15 mm. 



California (Sta. Barbara). 



The elongate basal joint of the hind tarsi will readily enable one 

 to identify this species. A single specimen taken by Mr. Gr. W. 

 Dunn. 



OXYPODA Mann. 



The types here assigned to Oxypoda cannot all be retained as 

 such, for those species having the antennal joints abruptly enlarged
