AMERICAN COLEOPTERA. 191 



This species is the one referred to csesareus, (Proc. Amer. Philos. 

 Soc. 1878, p. 597), but with the differences indicated. In that species 

 however, the golden pubescence is on the apical margin of the first 

 segment, and golden lateral spots on the next following as well as at 

 the sides of the ventral segments except the first. The determination 

 of t\\e synonymy of this and the next has been made from specimens 

 sent me by Mr. Fauvel. 



One specimen Detroit, Michigan, collected by Hubbard and 

 Schwarz. 



S. csesareus Cederh., Faun. Inqr. 335; Erichs. Genera Staphylinidae, 378; 

 ornaticauda Lee, New Species, 1863, p. 37. — Form moderately elongate. Head 

 orbicular, moderately densely punctured, a feeble smooth line posteriorly, 

 black, sparsely clothed with black pubescence, a spot near each eye and also 

 the constriction of the neck with golden pubescence. Antennae piceous, rufous 

 at base and tip. Thorax black, a little narrower than the elytra, slightly 

 longer than wide, sides behind the middle distinctly sinuate, disc moderately 

 convex, surface densely punctured, a narrow smooth median line, sparsely 

 pubescent. Scutellum with golden pubescence. Elytra as long as the thorax, 

 pale brownish or rufous, rufo-pubescent, finely punctate. Abdomen densely 

 finely punctulate and with black pubescence, posterior margin of the second 

 and a spot on each side of the fourth, fifth and sixth with golden pubescence, 

 beneath very sparsely punctate, the last four segments with golden pubescence 

 along their anterior margin interrupted at middle. Sides of pectus with golden 

 pubescence. Legs rufous, coxae piceous or black. Length .60 inch; 15 mm. 



One specimen Canada, collected by Mr. H. Ulke. Easily known 

 from every other species at present occurring in our fauna, by the 

 spots of golden pubescence at the sides of the ventral segments above 

 and beneath. 



S. VUlpinuS Nord., Symb. 53, 34; Erichs. Staph, p. 379; immaculatus 

 Mann. Brach. 22, 7. — Elytra uniformly brownish or pale castaueous not macu- 

 late. Abdomen finely punctulate clothed with black pubescence, along the 

 base of each segment with golden pubescence forming a broader spot at the 

 sides, last ventral segment above and beneath rufous. Coxae piceous, legs 

 entirely pale reddish-yellow. Length .70 inch; 18 mm. 



This species resembles niaculosus in most of its characters so that 

 merely the differences will be noted. 



Occurs in the Middle States, region usually with maculosus but 

 much less common. 



S. maculosus Grav., Micr. 165, 13; Erichs. Staph, p. 375; viduatus Fab., 

 Syst. El. ii, p. 591; erythi-opennis Mann. Brach. 22, 6. — Elongate, moderately 

 robust, piceous, opaque, legs and tip of abdomen pale. Head large, subtri- 

 angular, densely punctured and with short brownish pubescence. Eyes rather 

 broadly oval, truncate in front. Antennae a little longer than the head, pice- 

 ous, two basal joints paler. Thorax as wide as the head, as broad as long, 

 sides very feebly arcuate or nearly straight, base broadly arcuate, surface
