latter sometimes slightly piceoiis. Head twice as wide as long, feebly, evenly 

 convex ; eyes moderate, their surface perfectly continuous in convexity with 

 the front, and their lateral margin coarctate with the anterior margin of the 

 head, the latter perfectly evenly arcuate throughout in circular segment ; sur- 

 face finely and somewhat sparsely punctate ; antennse moderate, funicle very 

 slender, third joint as long as the next two, club as long as the five preceding 

 joints combined, the last joint one-third longer than the ninth and tenth com- 

 bined. Prothorax twice as wide as the head, and two and one-half times as 

 wide as long ; base transverse, very feebly broadly sinuate at each side of the 

 scutellum ; bead verj- feeble and entirely obsolete in lateral third ; sides evenly 

 arcuate ; disk very finely and rather sparsely punctate. Scutellum large, 

 nearly twice as wide as long ; sides feebly arcuate ; apex narrowly rounded ; 

 surface very finely, feebly punctate except toward the margins. Elytra about 

 three times as long as the prothorax, abruptly rounded behind ; sutural stria 

 very fine, forming a narrow sutural bead, continuous along the %cutellum with 

 the transverse basal stria, the single discal stria fine Imt distinct, joining the 

 sutural at the apex, and becoming obsolete at one-fifth the length from the 

 base ; disk highly polished, without reticulation, having equidistant approxi- 

 mate rows of fine rounded feeble punctures, the alternate rows being slightly 

 better defined, the punctures becoming obsolete toward base, and scarcely per- 

 ceptibly larger near the sides and apex. Abdomen clothed rather sparsely with 

 stitr semi-erect hairs. Legs robust ; middle and hind femora with a row of 

 sliflF hairs along the posterior lower edge, which become longer near the apex ; 

 anterior femora without trace of such hairs, posterior clothed on the lower 

 surface with coarse yellowish hair ; terminal spinules of posterior tibire short, 

 even, concealing the spurs, the corresponding tarsi short, with the first joint 

 about one-half as long as the second. Length 2.3-3.0 mm. 



Southern California ; Arizona ; New Mexico. 



In the type, which is one of the hirger specimens from Southern 

 California, the metastersal process pi'ojects well beyond the middle 

 coxae, the apex being- broadly arcuate or subtruncate, the mesoster- 

 num formina: a thickened and very strong apical bead ; the width 

 of the portion between the middle coxaj is three times as great as 

 the narrowest part of the prosternal process ; the latter is impressed. 

 In other specimens the metasternal process is nearly four times as 

 wide as the prosternal, more strongly arcuate, and more finely 

 beaded at apex. 



P. Sayi n. sp. — Evenly elliptical, convex, highly polished, about one-half 

 longer than wide, intense black throughout above and beneath, the antennae 

 just visibly piceous toward base. Head very minutely, rather sparsely punc- 

 tate ; eyes small ; antenna moderate, third joint as long as the next two 

 together, club very slender, the eleventh joint distinctly longer than the two 

 preceding together. Prothorax very minutely sparsely and feebly punctate, 

 extremely broadly feebly lobed at base ; beaded margin evident in the middle.
