86 MEMOIRS ON THE COLEOPTERA 



legs dark rufous; head three-fourths as wide as the prothorax and 

 wider than an elytron; antennae short and thick, but little longer 

 than the head and prothorax, dark testaceous in color, the medial 

 joints somewhat obconic, much less than twice as long as wide; pro- 

 thorax large, two-fifths wider than long, somewhat wider at base 

 than at apex, the sides rather feebly, subevenly rounded, becoming 

 oblique and broadly sinuate toward the sharp basal angles, which 

 are rather more than right, the sides of the base very oblique; mar- 

 gins moderately reflexed; anterior impression subobsolete; base 

 somewhat depressed and punctulate; stria very fine and subentire; 

 foveae small, rather deep and linear, the carina distinct; elytra two- 

 thirds longer than wide, only about a fourth wider than the pro- 

 thorax, parallel, the sides very gradually rounding toward the hu- 

 meri; striae rather fine, very feebly impressed, the punctures small, 

 widely separated except near the suture, the foveae near basal third 

 and apical fourth or fifth; seventh series as distinct as the sixth. 

 Length (cf 9 ) 3.8-4.0 mm.; width 1.2-1.3 mm. California (San 

 Diego). Three examples, taken by the writer on the shores of the 



bay ephippigerum Lee. 



Form much more abbreviated, convex, shining, black, generally with 

 piceous tinge, the elytra flavate, with a small scutellar cloud, a 

 transverse biarcuate clouded fascia at the middle and a bioblique 

 cloud between this and the apex, the small anterior fovea also black- 

 ish; entire under surface dark rufous to black, the legs always rufous; 

 head much smaller, scarcely as wide as an elytron and two-thirds as 

 wide as the prothorax, the eyes not quite so large or prominent; 

 antennae testaceous throughout, longer and less stout than in the 

 preceding, the medial joints about twice as long as wide; prothorax 

 shorter, nearly one-half wider than long, otherwise almost as in the 

 preceding, except that the oblique sides posteriorly are not distinctly 

 sinuate, being very broadly and just visibly so, with the very sharp 

 angles rather more than right; elytra about one-half longer than wide, 

 a fourth to nearly a third wider than the prothorax, parallel, the 

 sides very gradually rounding toward the humeri, ogival in apical 

 third; striae fine, subentire, only impressed suturad and there rather 

 faintly, the punctures fine, less separated than in the preceding, the 

 seventh stria and foveae almost similar. Length (cf 9 ) 3.4-3.8 

 mm.; width 1.18-1.28 mm. Utah (Little Salt Lake, Parowan and 

 Provo), Wickham. Eight specimens salinarium n. sp. 



In salinarium the elytra are frequently clouded with obscure 

 tint throughout, the peculiar markings then being indistinct, and 

 in one specimen they are nearly black, each with a long nubilous 

 rufous external spot toward the humeri. This species may have 

 been confounded with ephippigerum by Mr. Hayward, but it is 

 obviously distinct in its much more abbreviated form, smaller head, 

 less thickened and somewhat longer antennae and in the character 

 of the elytral ornamentation.
