found near San Francisco. It will be noted that californieus ex- 

 tends into the northern part of Monterey County where Lecontei 

 also occurs and that, while typical specimens of these two species 

 are readily separated, it is most natural that an intermediate form 

 should occur. 



O. lugubris Casey, I regard as a synonym of Edwardsii. The 

 following is taken from the paper by Major Casey (Ann. N. Y. Acad. 

 Sci., ix, pp. 288, etc.) : 



"Lateral margin of the prothorax distinctly reflexed, imperfectly attaining the 



"base, the sides almost straight and strongly convergent from apex to 



" base nearly as in Dejeani. 

 "Labrum bisinuate at apex, the median lobe broadly rounded and moderately 



"advanced K<lwar(ls<ii. 



" Lahrum more deeply bisinuate, the median lobe more prominent, with its apex 



"transversely truncate; elytra narrower, more elongate and more 



"parallel inoiifanus 



" Lateral margin fine and but slightly reflexed, the marginal bead not attaining the 



"base; sides distinctly convergent from the apex and almost straight. 

 " Labrum bisinuate, the median lobe more prominent than the sides, advanced 



"lobe truncate, body rather stout, 17.5 mm. long" lugubris. 



" Two males from California without accurate indication of local- 

 ity." The characters used are all subject to individual variation in 

 Edwardsii and do not indicate even a variety. 



O. punctifrons Casey and confliiens Casey, each described from 

 a single female from an unrecorded part of California, I regard as 

 synonyms of sequoiaram. The thorax " feebly vermiculato-rugose" 

 makes them either Edwardsii, Lecontei or seqiwiarum. The sides 

 " evenly arcuate," and the size make them not Edwardsii; the elytra 

 " widest at middle," make them not Lecontei. The "labrum bisinuate, 

 the median lobe moderately advanced and truncate;'' the "median 

 parts of the front sparsely or finely punctate ;" the form " moderately 

 ventricose" and " rather stout and feebly convex," are all characters 

 that exactly fit sequoiarum. Major Casey gives their differences as 

 follows : 



" Labrum bisinuate, the median lobe more prominent than the sides. 



" Elytral punctures separated through the greater part of the surface. 



piiiictifroiis. 



"Elytral punctures close-set and confluent nearly throughout • • ■coilfliieiis. 

 " Labrum deeply bisinuate, the median lobe more advanced", .sequoiariiiti. 



In making these quotations, I should say that some characters are 

 copied from the descriptions and others from the synoptic table, the 

 latter being mainly co ded.
