This small species resembles /e?'??u'??flYa in the distinctly defined 

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

 marked difference in antennal structure and feebly ])unctate meta- 

 sternum, sculpture of the elytra and much smaller size. 



S. riltieilS n. sp. — Narrowly ov^al, very convex, highly polished and pale 

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

 head, pronotum and metasternum subimpunctate ; elytra finely feebly and 

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

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

 thorax, the tliird 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 sixth, seventh longer than the 

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

 Prothorax 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. Ehjtra 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-epiraera extending halfway to the 

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

 ever only moderate in width. Leys 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 mesepimera.

 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
