Goleopterological Notices, VII. 303 



punctate near the base and apex, but elsewhere almost impunctate, the dark 

 median band not quite attaining the sides and extending broadly to base and 

 apex, with its confines rather nubilate ; median impressed line rather strong. 

 Elytra not quite as long as wide, behind the base much wider than the prothorax, 

 the subbasal and post-median irregular pale bands united longitudinally near 

 the middle of each, isolating a rather large ante-median black area near the mar- 

 gin ; dark sutural area feebly dilated and rhombiform near the apex ; striae not 

 very coarse, but broadly and deeply impressed, perfectly even and regular, the 

 punctures rather large, deep and very close-set, extending almost to the apex ; 

 intervals moderately convex. Under surface piceous-brown throughout, the 

 sides slightly more flavate ; legs pale brown. Length 4.8 mm. ; width 3.0 mm. 



California (Siskiyou Co.). 



The description is taken from the male type, which is the only 

 example known to me. The species somewhat resembles gemma, 

 but differs in outline, in its sombre coloring, finer pronotal, but 

 much coarser and more regular elytral punctures, more narrowly 

 rounded elytral apex, and in numerous other characters. 



O. soliduiu. — Oblong-oval, only very moderately convex, the lustre 

 _generally rather strongly alutaceous ; dark markings with a strong but some- 

 what dark metallic-green reflection. Head with a large frontal pale impunc- 

 tate area which is broadly angulate posteriorly, the green basal area with nu- 

 merous moderate punctures. Prothorax slightly more than twice as wide as 

 long, the sides quite strongly arcuate, convergent anteriorly, becoming parallel 

 behind the middle ; punctures moderate in size, deep, rather close-set, extend- 

 ing to the basal angles but almost obsolete in the green transverse band, the 

 latter not quite attaining the side margins and only narrowly attaining the 

 apex on the median line, broadly attaining the base, with two approximate 

 pale spots at the middle, the dark areas everywhere sharply defined ; median 

 line fine. Elytra as long as wide, the sides subparallel and but feebly arcuate, 

 very broadly rounded in apical third ; striae rather fine but strongly impressed, 

 somewhat irregular, and, to some extent, unevenly spaced, the punctures fine 

 but rather strong and close-set, obliterated near the apex ; sinuous pale bands 

 narrow and very irregularly zig-zag, the post-median much broken up ; sub- 

 apical pal e spot finely bifurcate anteriorly ; sutural rhombus near the apex 

 broad. Under surface blackish throughout, the abdomen not paler, except a 

 fine marginal line ; hypomera, epipleurse and legs pale flavate-brown. Length 

 6.2-7.0 mm.; width 3.6-4.5 mm. 



California ( Marin to Humboldt Cos.). 



This species is common in the coast regions of California, north 

 of San Francisco, and exists inmost cabinets, but commonly con- 

 fused with dentatum, which it resembles in coloration. The pale 

 spots of the elytra are always narrower and more disintegrated, 

 however, than in that species, and the form of the body is more ob- 

 long and parallel ; the pale frontal area of the head is limited pos-
