tured, with the interstices smooth and shining; sides slightly margined and a little rounded ; basal 
margin not sinuated, produced towards the scutellum, with the angles rectangular. Scutellum small, 
triangular. lytra generally castaneous, rather long, broader and more than one half longer than the 
head and thorax, widest before the middle; moderately and rather remotely punctured, with the inter- 
stices smooth and shining ; sides slightly margined and a little rounded; extremities broad and rounded. 
Abdomen acuminate, brightly rufescent. Legs moderate, bright rufous. Underparts rutescent.

Numerous examples. Differs from S. bilimeki in its larger size, broader form, finer 
and remote sculpture of its elytra, and shorter legs and antenne.

Late ovatum, convexum, nitidissimum, confertim punctatum, aterrimum ; capite lato, brevi; oculis magnis, sat 
prominentibus; pronoto magno, minute et confertim punctato, interstitiis glabris, nitidis, lateribus rotun- 
datis, vix marginatis, margine basali vix sinuata, scutellum versus valde producta, angulis fere rectis ; 
elytris brevibus, quam caput atque pronotum parum longioribus, vix latioribus, prope humeros latissimis, 
profunde et confertissime punctatis, interstitiis alutaceis, stria suturali modica, lateribus leviter rotundatis, 
sat late marginatis, apicibus vix rotundatis, rufescentibus; abdomine rufescente ; pedibus atque antennis 
longis, gracilibus, rufescentibus. Long. corp. 2°25 millim. ; lat. 2 millim. 
Body broadly ovate, convex, and very shining, closely punctured, deep black. Head broad and short; eyes 
large and rather prominent; antenne long and slender, rufescent. Thorax large, minutely and closely 
punctured, with the interstices smooth and shining; sides rounded, scarcely margined ; basal margin 
scarcely sinuated, much produced towards the scutellum, with the angles nearly rectangular. Scutellum 
minute, triangular, covered by the thorax. lytra short, rather longer but scarcely broader than the 
head and thorax, widest near the shoulders; deeply and very closely punctured, with the interstices 
alutaceous ; sutural stria moderate; sides faintly rounded, and rather broadly margined ; extremities 
scarcely rounded, rufescent. Abdomen rufescent. Legs long and slender, rufescent. Underparts rufo- 
piceous, with the mouth and venter paler. 
Hab. Mexico, Teapa!, Guanajuato (Sallé). 
Differs from the preceding species in its smaller size, short and broad form, deep 
sculpture of the elytra, and rufescent legs and antenne. The examples before me 
agree sufficiently well with Reitter’s description of S. bilimeki to be identified therewith.
