 hind tarsi less than one-third the length of tibia?. 

 g. Small black species; hind femora black; head broad, about one-

Small elongate-oval, pubescent species having the head 

 broader across eyes than long, its front strongly deflexed ; ver- 

 tex convex, carinate at base; pronotum short, subtrapezoidal, 

 twice as broad across base as long, hind margin truncate, hind 

 angles rounded, calli subobsolete ; mesoscutum concealed ; elytra 

 entire, surpassing abdomen, cuneus subhorizontal ; beak reach- 

 ing first ventral. One of the three known North American 

 species occurs in Florida. 



1025 ( — ). Sthenarus plebejus Reuter, 1907b, 26. 



Head, pronotum and scutellum fuscous-black; elytra and humeral 

 angles of pronotum dull brownish-yellow to fuscous-brown, cuneus con- 

 colorous; membrane dusky-hyaline, the apical half iridescent and mi- 

 nutely rugose; legs pale straw-yellow, tarsi and apical third of tibia? 

 tinged with fuscous ; under surface dark fuscous-brown tinged with red- 

 dish, middle of ventrals paler. Joint 1 of antenna? straw-yellow, two- 

 fifths as long as width of vertex; 2 reddish-yellow, darker at tip, its 

 apical half slightly thickened, four and one-third times as long as 1 ; 

 3 and 4 dusky, subequal in length, united two-thirds as long as 2. Upper 

 surface sparsely clothed with long fine yellowish hairs. Front half of 

 pronotum smooth; hind one finely transvei'sely rugose. Scutellum and 

 elytra similarly rugose. Length, 2 — 2.8 mm.
