centiform, although not at all deeply impressed. Abdomen somewhat coarsely 

 and densely, asperately punctate, and very coarsely pubescent. Legs very 

 short and somewhat robust ; the posterior tibiae more strongly arcuate within, 

 strongly setose, nearly spinulose externally ; spurs very small, slender, un- 

 equal; the corresponding tarsi four-fifths as long as the tibiae, one-half longer 

 than the anterior, with the first joint about two-thirds as long as the second. 

 Length 1.0-1.2 mm.

The metasternal process is short and very broad, coarsely reticu- 

 late, but with the lines very feeble, truncate at apex, very sparsely 

 pubescent, the mesosternum before it moderate in length, not very 

 tumid, pubescent at the sides only. The prosternal process is 

 broad, the terminal setose spines long and conspicuous. 



This is the most minute species known to me within our faunal 

 limits, and is so distinct in all its characters that it cannot be mis- 

 taken for any other. 



S. piisilllis Lee. — Proc. Ac. Phil., 18.56, p. 17. — Oval, slightly attenuate 

 behind from anterior third, strongly convex, piceous-black throughout above, 

 pale testaceous beneath, strongly shining. Head very minutely, feebly punc- 

 tate, not reticulate; eyes rather large ; antennae moderate, third joint clavate, 

 nearly as long as the next two together, outer joints of funicle but slightly 

 more robust, seventh much longer than the eighth, the latter strongly trans- 

 verse, club rather long and slender, the ninth joint longer than wide, longer 

 than the tenth and much shorter than the eleventh. Prothorax excessively 

 minutely and feebly punctate, not at all reticulate ; basal lobe extremely feeble, 

 broad, the marginal bead almost obsolete. Scutellum one-half wider than 

 long. Elytra finely and distinctly reticulate in wavy broken transverse lines ; 

 discal stria obsolete at basal third, rather deeply impressed, punctate ante- 

 riorly ; siarface with rows of punctures of which the two nearest the suture are 

 very distinct, but obsolete in basal and apical third, rather deeply impressed 

 and very narrowly but strongly crescentiform ; the rows thence to the sides 

 composed of more minute and very feeble punctures, which are not larger or 

 more distinct, and rather more confused near the sides, except a regular 

 series just within the extreme lateral bead which is composed of slightly 

 larger, more closely placed and feebly dilated punctures. Abdomen very 

 sparsely, feebly punctate and pubescent. Legs slender ; posterior tibiae 

 slightly wider at apical third than at apex, spinose, especially externally ; 

 terminal spurs minute, the tarsi slender, with the basal joint rather more 

 than one-half as long as the second Length 1.1-1.3 mm.

The post-coxal portion of the mesosternum is indefinitely limited 

 and angulate behind ; the metasternum is very strongly reticulate, 

 and rather densely and distinctly punctate and pubescent in the
