and covered with a thick silvery pubescence; the vertex broadly ferruginous; the 

 clypeus fringed with long pale fulvous hair ; the mandibles entirely black. The scape 

 of the antennae covered with white hair ; the flagellura brownish beneath ; the third 

 joint about twice the length of the fourth, not much narrower at the base than at the 

 apex. The thorax is not much longer than the head, the base rounded; sharply 

 narrowed from the tubercle ; the edges rough, the sides of the median segment denti- 

 culate ; coarsely punctured, and covered with white hair ; the apex black (the black 

 triangularly projecting in the middle), obliquely rounded, densely covered with long 

 white hair. The pleurae shining, impunctate, except at the apex, which has some 

 moderately large punctures ; covered with a short white pile. The basal segment of 

 the abdomen covered with long white hair ; on the base of the second segment are two 

 oval transverse orange marks, and at the apex are two larger round ones ; the third and 

 following segments are covered with white hair ; the pygidium black, covered with 

 pale fulvous hair. The first ventral segment, triangular at the base, shining, the sides 

 depressed, the keel blunt, rising gradually at the base ; the punctures on the second 

 segment large and irregular ; the apices of the segments fringed with white hair. 

 The femora and tibiae sparingly covered with long whitish hair, that on the tibiae 

 having a fulvous tinge ; the pubescence on the tarsi bright ferruginous.

Agrees almost* in coloration with S. cordovensis, except that the pleurae are reddish 

 at the base, and that there is a black triangular mark at the base of the mesonotum ; 

 also differs in the hinder edges of the head not being broadly rounded, while behind it 

 is distinctly convex. 



Head distinctly wider than the thorax, transverse in front, convex behind ; the 

 edges rounded posteriorly, but not broadly ; coarsely punctured ; the vertex ferrugi- 

 nous, the hair on it black ; the apex of the clypeus rounded, dull piceous ; the 

 mandibles ferruginous before the apex, their base bearing long white hair. The scape 

 of the antennae covered with white hair, its apex ferruginous ; the flagellum obscure 

 brownish beneath ; the third joint distinctly narrowed at the base, rather more than 

 twice the length of the fourth. The thorax not much longer than the head, coarsely 

 punctured ; the mesonotum bearing blackish hair, the median segment with longer 

 white hair ; the base rounded ; the apical half distinctly narrowed ; the apex with 

 the sides coarsely toothed at the base, oblique ; ferruginous, a somewhat triangular 

 elongate mark at the base and apex black. There is a subtriangular ferruginous mark 

 on the pleurae at the base, the central part of this being striolated ; the apex has 

 widely-separated punctures ; the base of the mesopleurae is obscure ferruginous. The
