100 GEO. H. HORN, M. D. 



S. pacificns Or. — Oval, outline nearly continuous, black shining, each ely- 

 tron with a larjfe reddish yellow oval spot slightly in front of middle, anterior 

 angle of thorax yellow. Head sparsely punctate, color either yellow or piceous. 

 Thorax slightly narrowed in front, sides feebly arcuate, sparsely iinely punctate, 

 basal marginal line distinct. Elytra moderately coarsely, not closely punctate ; 

 prosternnm smooth at middle, the elevated lines parallel and entire ; metasternum 

 roughly punctured at the sides, the mesocoxal line arcuate, joining the suture 

 one-third from the front. Abdomen moderately, coarsely and closely punctate, 

 the metacoxal line forming a complete arc as long as the first segment; femora 

 piceous, knees, tibise and tarsi rufo-testaceous. Length .08 — .10 inch. ; 2 — 2.5 mm. 

 PI. II, fig. 7. 



There does not appear to be any variation in the coloration of the 

 specimens examined, except as to the head, which may be either 

 yellow or black, independently of sex. The color of the anterior 

 angles of the thorax is not sexual, as Crotch's description would 

 seem to indicate. 



Hab. — California, Calaveras to Los Angeles. 



S. strabus n. sp. — Oval, convex, outline continuous, black, shining, each 

 elytron with an oblique red spot, nearly all of which is in front of middle. Head 

 sparsely punctate. Thorax slightly narrower in front, sides feebly arcuate, basal 

 marginal line distinct, surface finely not closely punctate. Elytra sparsely, in- 

 distinctly punctate; prosternal elevated lines not reaching the anterior margin 

 of sternum ; metasternum at sides coarsely, closely punctured, the mesocoxal line 

 arched, joining the suture one-third from apex. Abdomen closely punctate, the 

 metacoxal line forming a complete arc, as long as the segment, the enclosed space 

 smooth. Legs piceous, tibia? and tarsi somewhat paler. Length .10 inch. ; 2.5 

 mm. PI. II. fig. 6. 



Of this species but one female specimen has been examined. It 

 resembles pacif{ci(i<, but is more convex and broader, the red spot is 

 oblique, the thorax entirely black,

S. flebilis n. sp. — Eegularly oval, black, head and sides of thorax broadly 

 reddish yellow, each elytron with a reddish yellow triangular spot near the apex. 

 Head sparsely punctate. Thorax narrowed in front, sides feebly arcuate, sides 

 broadly reddish yellow, this extending narrowly along the apex, surface very 

 sparsely punctate, the basal marginal line indistinct. Elytra moderately coarsely, 

 not closely punctate ; prosternal lines parallel and entire; metasternum coarsely 

 punctate at sides, the mesocoxal line arcuate, joining the suture one-fourth from 

 the front. Abdomen black, closely punctate, the metacoxal line forming a com- 

 plete arc a little shorter than the segment. Legs piceous. Length .08 inch. ; 2 mm. 



The elytra are paler along the apical border, but without forming 

 the red edge characteristic of the forms allied to eo/Arri-y. To this 

 latter species it has considerable resemblance apart from the moder- 

 ately large reddish spot near the apex of the elytra, which may be 

 called triangular with rounded angle.=*. 



Hub.— Arhona, Gila Bend (Wickham).
