rather coarse punctures widely separated throughout, not different 

 near the sides; sparsely punctured scutellum ogival, with the sides 

 more arcuate basally; elytra as long as wide, a third wider than the 

 prothorax, circularly rounded behind about the middle, the sides 

 parallel, broadly arcuate; punctures very fine and sparse, but little 

 more evident suturad, the infra-humeral impression moderate; disk 

 with a few fine impressed lines; pygidium very shining, the rugulosity 

 not very fine and decidedly feeble, mingled as usual with small 

 punctures bearing long erect hairs; legs black, the femora with very 

 feeble greenish lustre. Length (cf ) 13.7-15.0 mm.; width 8.7-9.2 

 mm. California (San Bernardino), Dunn. Four examples. 



rotunda n. sp. 



Body more elongate-oval and larger in size, the bristling pubescence 

 fulvescent, not so long or conspicuous on the under surface and, on 

 the elytra, only visible as short erect hairs arranged in four or five 

 very regular longitudinal single lines, the first near the suture; color 

 deep black, the anterior parts above with only the faintest blue-black 

 lustre, the under surface and legs deep black, without trace of metallic 

 lustre; head and clypeus nearly as in the preceding; prothorax rela- 

 tively rather small, only about three-fourths wider than long, the 

 sides subparallel and almost evenly and strongly rounded; basal 

 angles very obtuse, rounded; punctures coarse, widely separated, 

 but little closer laterally, intermingled with fine sparse punctures, 

 which are not similarly evident in any of the preceding species; 

 elytra oval, slightly longer than wide, two-fifths wider than the 

 prothorax, circularly rounded in about posterior half, the sides 

 slightly prominent near basal third in the female; suture finely 

 brownish; punctures small, sparse, with still smaller punctures 

 sparsely intermingled, the general tendency to linear arrangement 

 rather noticeable; pygidium (d 71 ) finely, closely, or ( 9 ) still more 

 finely, densely and more uniformly, rugulose throughout, slightly 

 shining; last ventral in both sexes more finely and closely punctured 

 as usual. Length (cf 9 ) 17.0-17.5 mm.; width 10.3-10.6 mm. 

 Southern California (the exact locality unknown). Three ex- 

 amples seriata n. sp. 



7 Form broadly oval, convex, shining; elytra brownish-rufous; under 

 surface and pygidium black, with bright green lustre, the tarsi 

 black, feebly metallic; pubescence long, erect, cinereous, not con- 

 spicuous beneath, except at the sides and along the upper femoral 

 edges, moderate anteriorly above and sparse but distinct on the 

 elytra medio-basally and partially subserial in arrangement; head 

 and clypeus both black, with bright green lustre and closely punctate, 

 the punctures perforate and deep, with others smaller and shallow 

 intermingled; clypeus semicircular, non-metallic and strongly 

 reflexed peripherally; prothorax moderate, three-fourths wider than 

 long, widest behind the middle, where the sides are more rounded, 

 gradually converging, feebly arcuate and serrulate thence to the 

 apex; basal angles very obtuse but not much rounded; basal bead 

 only obsolete medially; punctures coarse, well separated, somewhat 

 less coarse near the sides; scutellum coarsely and rather closely
