528 Coleoplerological Notices, V. 



tennae pale ; head and pronotum subimpunetate ; elytra distinctly, 

 sparsely punctate, the punctures becoming finer toward base. An- 

 tennas not quite as long as the head and prothorax, the third joint 

 slightly longer than wide, only a little shorter than tlie fourth, 

 which is barely twice as long as wide; fifth about as long as the 

 third and fourth together; sixth slender, very long, distinctly 

 longer than the third, fourth and fifth combined, fully as long as 

 the seventh, the latter strongly inflated within. Prothorax short, 

 one-half as long as the elytra. Scutellum distinct. Elytra a little 

 wider at basal fourth than at base, the basal stria extending fully 

 to the middle but approaching very close to the pronotum ; sutural 

 deep, feebly and somewhat unevenly arcuate; external apical angles 

 distinctly rounded. Mes-epimera £,earcely extending niidway to the 

 coxae ; met-episternal suture fine and very oblique. Metasternum 

 coarsely, strongly punctured toward base except along the hind 

 coxae. Posterior tarsi slender, the basal joint as long as the next 

 three. Length 1.8 ram.; width 1.25 mm. 



New York. The very long sixth antennal joint, more than equal 

 to the preceding three together, the coarsely punctured metasternum 

 and i)ale apex of the elytra, will readily identify this species, which 

 is much larger and rather more broadly oval than the next. 



S. evanesceilS n. sp — Narrowly oval, black, highly polished; elytra 

 with a pale apical margin ; aiiteniije, legs and abdomen toward apex pale, 

 rufous ; head and pronotum impunctate ; elytra finely, sparsely punctate, 

 the punctures completely evanescent and effaced in basal half; metasternum 

 extremely minutely, sparsely punctulate. Head vertical, moderate ; eyes 

 large, separated by one-half more than their own width ; antennae not as long 

 as the head and prothorax, the third joint very small, triangular, scarcely 

 longer than wide, fourth very short, barely twice as long as wide, fifth four 

 times as long as wide, distinctly longer than the third and fourth together 

 and a little shorter than the sixth. Prothorax two-thirds wider than long, 

 the basal lobe small, strongly rounded; basal angles produced and acute. 

 Scutellum distinct. Elytra about as long as wide, twice as long as the pro- 

 thorax, a little wider at basal fourth than at base ; truncate apices nearly 

 three-fourths of the maximum width ; angles distinctly rounded ; sutural stria 

 fine, nearly straight, the basal fine, scarcely attaining the middle and distant 

 from the pronotum. Mes-epimera rather wide, barely extending halfway to 

 the coxae; met-episternal suture very fine, strongly oblique, the parapleurre 

 wide behind ; epimeral suture fine but distinct. I'ost-coxal plate of the first 

 ventral rather strongly rounded behind and extending two-fifths of the length. 

 Legs slender; basal joint of the hind tarsi not as long as the next three. 

 Length 1.4-1.55 mm. ; width 0.9-1.0 mm.
