Iowa ; Texas. 



This small species resembles terminata in the distinctly defined 

 pale apex of the elytra, but may readily be known by the strongly 

 marked difference in antennal structure and feebly punctate meta- 

 sternum, sculpture of the elytra and much smaller size. 



S. rulieilS n. sp. — Narrowly oval, very convex, highly polished and pale 

 rufo-testaceous throughout, subglahrous, the hairs very distant but visible ; 

 head, pronotura and metasternum siibimpunctate ; elytra finely feebly and 

 very sparsely punctate. Head vertical, the eyes moderate, distant by nearly 

 twice their own width ; a-ntennsp somewhat longer than the head and pro- 

 thorax, the third joint almost twice as long as wide, feebly narrowed toward 

 base, barely one-half as long as the fourth, which is evenly cylindrical and 

 four times as long as wide, distinctly shorter than the fifth, the latter thicker 

 beyond the middle, rather longer than the stxth, seventh longer than the 

 fifth, inflated and arcuate within, eleventh much longer than the tenth. 

 Protliorax two-thirds wider than long, the apex one-half as wide as the base ; 

 scutellar lobe moderate, rounded ; basal angles produced and acute. Scutellum 

 distinct, a little wider than long. Elytra fully as long as wide, twice as long 

 as the prothorax, a little wider at basal third than at base, the truncate apex 

 barely two-thirds of the maximum width ; angles distinctly rounded ; basal 

 stria obsolete, the rather widely and deeply impressed sutural stria simply 

 turned outward slightly at base. Mes-epimera extending halfway to the 

 coxje ; met-episternal suture fine and distinctly oblique, the episterna how- 

 ever only moderate in width. Legs slender, the basal joint of the hind tarsi 

 scarcely longer than the next two. Length 1.7-1.9 mm. ; width 0.95-1.05 mm. 



Massachusetts; New York (Catskill Mts. and Long Island). 



The pale coloration of this species recalls rufula very greatly at 

 first sight, but it is more elongate and differs altogether in the form 

 of the mes-epimera. 



S. rufula Lee— Proc. Ac. Nat. Sci., Phila., 1860, p. 323. 



Oval, rather short and stout, highly polished and pale rufo-testa- 

 ceous throughout, the head and pronotum subimpunctate ; elytra 

 extremely finely sparsely and obsoletely punctulate. Ar'tennse long, 

 the third joint short, constricted at base, barely one-half as long as 

 the fourth, which is four times as long as wide and distinctly shorter 

 than the fifth, the latter a little longer than the sixth. Prothorax 

 rather long, scarcely one-half wider than long ; basal angles pro- 

 duced and acute. Scutellum excessively minute but present. Ely- 

 tra not quite as long as wide, not much more than one-half longer 

 than the prothorax ; sutural stria deep, curved outward for a short 

 distance at base, the basal stria represented thence to the middle by
