UROXYS.— SCATIMUS. 43 



UROXYS. 



Uroxys, Westwood, Trans. Ent. Soc. Lond. ser. I, iv. p. 229 (1842) ; Harold, Col. Hefte, iii. p. 33 

 (1868). 



Seventeen species of this curious little genus, confined to Tropical America, have 

 been described. 



1. Uroxys micros. (Tab. II. fig. 22.) 



U. pygmaeo (Harold) affinis, paullo major, elytris perspicue crenato-striatis, etc. Oblongo-ovatus, nigro-seneus 

 vel ferrugineus, politus ; clypeo bidentato, juxta dentes leviter sinuato nee subdentato, vix punctulato, 

 vertice lsevi ; thorace leevi, sulco submargiaali prof undo, basi immarginato, distanter punctato ; elytris 

 striatis, striis versus latera et apicem profundioribus, distanter crenato-punctatis ; pygidio basi sulco semi- 

 circular! profundissimo. 



Long. 4-4f millim. 



Ilab. Guatemala, La Gavia 2000 feet {Champion). 



The singular curved sulcus on each side of the base of the pygidium exists in 

 XT. pygmmus, but it is broader and deeper in the present species. The sides of the 

 thorax exterior to the marginal furrow are also more convex in U. micros than in 

 U. pygmceus. The eyes above are large and the mesosternal suture angulated, as in 

 the rest of the genus. 



2. Uroxys aphodioides. 



U. elongato (Harold) affinis ; minus convexus, niger, nitidus, vertice cuprascente ; capite fere laevi, vertice valide 

 bidentato, fronte tuberculo conico ; thorace (elytris latioribus) subtilissime punctulato, sulco laterali 

 flexuoso margineque medio angulato et antice arcuato, basi puuetato-marginato ; elytris crenato-striatis, 

 interstitiis convexis ; corpore subtus impunctato ; mesosterno longissimo, sutura parum angulato ; pygidio 

 valde convexo, politissimo ; tibiis 4 posticis extus irregulariter dentatis. 



Long. 10 millim. $ ? 



Ilab. Nicaragua (coll. Bates). 



One example, which, from the absence of curvature in the anterior tibiae, I judge to 

 be a female. It was obtained, I think, from Dr. Seemann's collections made at Javali. 

 It resembles TJ. elongatus in little except the uni-tuberculate forehead. 



3. Uroxys rodriguezi. 



Uroxys rodriguezi, Preudhomme de Borre, Ann. Soc. Ent. Belg.. xxx. p. 107 (1886)\ 

 Eab. Guatemala 1 . 



SCATIMUS. 



Scatimus, Erichson, Archiv fur Naturg. 1847^ i. p. 110. 



A genus peculiar to Tropical America. Three species only have been described.
