and thorax. The diflferences between this and luteipes are found 

 under that species. 



Occurs in California, at Tejon and vicinity. 



S. luteipes Lee, Proc. Acad. 1861, p. 342. — Form moderately elongate, 

 body beneath and legs pale rufous, above bluish, abdomen above piceous vary- 

 ing to partially rufous. Head orbicular, slightly transverse, surface moderately 

 densely punctured and with feeble smooth median line. Eyes slightly oblique, 

 subtruncate in front. Antennae extending to middle of thorax, rufous or 

 piceous, the basal joint always pale. Thorax a little narrower than the head, 

 longer than wide, broader at apex than base, sides distinctly sinuate behind 

 the middle, surface densely punctured with moderately wide smooth median 

 line. Scutellum punctured, pubescent. Elytra as wide as the head, a little 

 longer than the conjoined width, surface more densely and finely punctured 

 than the thorax and sparsely clothed with brownish pubescence. Abdomen 

 above sparsely and indistinctly punctulate, sparsely clothed with brownish 

 pubescence. Body beneath and abdomen sparsely finely punctulate and sparsely 

 clothed with rufous pubescence. Length .60 inch; 15 mm. 



The head, thorax and elytra are always very distinctly blue, the 

 inflexed portion of the latter being often paler or even rufous. The 

 abdomen above may be entirely piceous or the sides only rufo-piceous, 

 frequently the rufous color invades nearly the entire surface of the 

 apical segments. The body beneath, abdomen and legs are entirely 

 rufous, the sides of the metasternum and the apical margins of the 

 ventral segments slightly darker. 



The only species for which this might be mistaken is saphyrinus 

 in which the body beneath and abdomen are black, the segments 6 — 8 

 of the latter bright rufous. 



Occurs in California, from Mariposa to Los Angeles. 



S. erythropterus Linn., Faun. Suecc. 842; Erichs. Genera Staphy- 

 linidse p. 377; ccesareus J Lee, Proc. Am. Phil. Soc. 1878, p. 599. — Form 

 moderately elongate, piceous, elytra and legs pale. Head orbicular, densely 

 punctured, a narrow smooth line at middle, nuchal depression moderately 

 deep, surface sparsely clothed with short black pubescence and with a small 

 spot of golden pubescence above each eye in front, and also a line of 

 similar pubescence in the neck. Eyes oval, oblique, subtruncate in front. 

 Antennse attaining the middle of the thorax, piceous, base and tip paler. 

 Thorax as wide as the head, a little longer than wide, sides very feebly arcu- 

 ate, subsinuate posteriorly, base broadly arcuate, surface densely punctured 

 with feeble median line, surface sparsely pubescent. Scutellum velvety. Elytra 

 very little wider than the thorax, a little wider conjointly than long, surface 

 subopaque, sparsely pubescent with brownish and black hairs intermixed. 

 Abdomen feebly shining, sparsely finely punctulate and with a velvety aspect, 

 sparsely clothed with short black hairs, the second segment margined at apex 

 with golden pubescence interrupted at middle ; beneath very sparsely punctate, 

 feebly shining, sparsely clothed with black hairs. Body beneath rather sparsely 

 punctate. Coxse piceous, legs pale, rufous. Length .54 inch; 13.6 mm.
