New York ; Michigan ; Texas. 



The head is strongly retracted within the prothorax in each of 

 the single representatives of the above localities. The nietasternal 

 process is rather narrow, short, strongly rounded at apex, and 

 strongly beaded at the sides, the mesosternum in front of it un- 

 usually long but almost perfectly flat and not setose, except very 

 sparsely at the sides. Prosternal process rather wide, extending 

 rather further than usual beyond the coxae, with the free edge 

 strongly, transversely arcuate, and very acute ; the process is very 

 minutely beaded at the sides, but not at all at apex, where the seti- 

 form spinules are short, erect and very widely spaced. 



This species is quite as aberrant as conver-gens, but does not at 

 all resemble it in the structure of the sterna. The post-coxal portion 

 of the mesosternum is not as long as in some other species, but is 

 very clearly and abruptly limited throughout by an evenly arcuate 

 declivous line. The terminal setiB of the prosternal process are not 

 quite as short as in convergens, but are very much more widely 

 spaced, being only about four in number, 



S. eloilgatlllus n. sp. — Subelongate, convex, polished, black above, the 

 elytra gradually slightly paler at apex ; under surface pale, rufo-testaceous 

 throughout ; sides feebly convergent behind from the base of the elytra. Head 

 retractile, feebly convex, rather closely but extremely finely punctate ; surface 

 not reticulate; eyes rather large; antennse slender, the club slender, some- 

 what compact, attenuate toward base, the ninth joint rather longer than wide, 

 longer and narrower than the tenth, eleventh about as long as the two preced- 

 ing. Prothorax rather elongate, scarcely twice as wide as long ; sides evenly, 

 distinctly arcuate ; surface polished, not at all reticulate, excessively minutely 

 punctate, the punctures not very sparse ; basal lobe extremely feeble, the 

 bead fine but distinct near the middle, obsolete laterally, Scutellum small, 

 nearly twice as wide as long, angulate ; sides straight, abruptly arcuate near 

 the base. Elytra rather distinctly more than twice as long as the prothorax ; 

 sides nearly straight toward base, together somewhat narrowly rounded 

 behind ; basal stria fine, reflexed along the scutellum, the single discal stria 

 very coarse and deeply impressed, becoming gradually feebler and punctate 

 toward base ; disk coarsely and strongly reticulate in well-defined transverse 

 wavy lines, the sculpture becoming abruptly almost obsolete near the base, 

 having rather distant rows of coarse deeply-impressed rounded punctures, 

 which are scarcely perceptibly stronger toward the suture, the rows not 

 attaining the base and becoming gradually obsolete toward the apex, the 

 punctures of the lateral rows distinct but not dilated, the rows not accom- 

 panied by impressed lines. Length 1,3 mm.
