punctured; elytra very nearly as wide as long, circularly rounded 

 behind about the middle, the sides thence converging slightly to the 

 base, fully two-fifths wider than the prothorax; punctures sparse, 

 fine, coarser and obliquely subrugulose suturad; lateral impressions 

 moderate; lateral edge serrulate basally; pygidium shining, finely, 

 irregularly rugulose and with moderate sparse punctures; mentum 

 concave anteriorly. Length (cf) 14.7-15.7 mm.; width 8.7-9.0 

 mm. California (near San Diego). Three examples. 



rubripennis n. sp. 



8 Form oblong-oval, more elongate than the preceding, convex, shining, 

 under surface black, with green lustre, the basal parts of the abdom- 

 inal segments cupreous; legs black, with bright green lustre, the 

 tarsi less metallic; pubescence luteo-cinerous, long, rather coarse, 

 dense on the sterna and parts of the femora, sparser on the abdomen, 

 close and conspicuous on the head and pronotum, sparser, not so long 

 and more reclining on the medio-basal parts of the elytra, almost 

 wanting elsewhere; head densely sculptured, bright green, the clypeus 

 semicircular, deep black, without metallic lustre, the edges well 

 reflexed; eyes even smaller than usual; prothorax relatively larger 

 but throughout nearly as in the preceding, though with coarser 

 pubescence and with the converging sides anteriorly not definitely 

 serrulate; scutellum coarsely, irregularly and much less closely 

 punctured; elytra fully a fifth longer than wide, more rapidly 

 rounding and obtuse in about apical third, only a fourth or fifth 

 wider than the prothorax, the sides parallel and feebly arcuate; 

 punctures fine and sparse but deep and distinct, intermingled with 

 larger and pubiferous punctures medio-basally; lateral impressions 

 deep; humeral angles less rounded than usual; pygidium bright green 

 but only slightly shining, finely but strongly, densely rugulose and 

 closely clothed with long coarse pale hairs; mentum feebly concave 

 anteriorly; abdomen with the punctures closer than in the preceding. 

 Length (cf ) 15.7 mm.; width 8.6 mm. Southern California (locality 

 unrecorded) nigripennis n. sp. 



9 Body oblong-oval, rather abbreviated and only moderately convex, 

 greenish-blue and not very shining anteriorly, the elytra dark 

 brownish-red and strongly shining; under surface rather shining, 

 green throughout and with the cinerous vestiture very long, dense 

 and conspicuous, only a little sparser on the abdomen; legs black, 

 with dark violet-blue lustre; head and pronotum with the hairs very 

 long, fine, ashy-sericeous, dense and conspicuous, the elytra with 

 only a few erect hairs medio-basally; head densely punctate; clypeus 

 flat, semi-elliptical, with shorter vestiture, greenish in lustre, the 

 periphery abruptly and moderately reflexed; prothorax nearly twice 

 as wide as long, widest at the middle, the sides arcuate, less so and 

 converging apically and basally, the apical angles shorter and blunter 

 than usual, the basal obtuse but not much rounded; base broadly 

 arcuate, the lobe very broad and but feebly differentiated, the bead 

 visible only toward the sides; punctures coarse and very confluent; 

 scutellum green, with moderate, rather close-set punctures, wholly
