PJil/tophagous Culeoptera, ^^c. 249 



sat elongati ; coxis anticis elevatis, subrotundatis ; femo- 

 Tibus posticis leviter incrassatis ; tibiis ad apicem obsolete 

 canaliculatis, anticis quatuor muticis; uncjuiculis appen- 

 diculatis. 



Eugonia ought to stand near Crepidodera ; it may be 

 separated from that genus by the unarmed apices of the 

 four anterior tibias and by the slender hinder thighs. 



Eugonia dimidiatipennis. 



Ovata, modice convexa, rufo-fulva, nitida, oculis, an- 

 tennis, abdomine pedibusqne (femoribus anticis quatuor 

 basi et infra, posticis basi, exceptis), nigris ; thorace con- 

 vexo, Isevi, impunctato ; elytris modice convexis, infra 

 basin non depressis, punctato-striatis, striis ante medium 

 uniseriatim, pone medium confuse biseriatim punctatis, 

 striis prope apicem penitus confusis ; subopacis, sordide 

 rufo-fulvis, a medio ad apicem cajruleo-nigris. 



Long. 2 lin. 



Hab. — Chanchamayo. 



Vertex shining, impunctate ; encarpce transverse, well 

 defined, carina strongly elevated ; antennaj filiform, three- 

 fourths the length of the body, the basal joint rufo-fulvous, 

 the rest black. Thorax twice as broad as long ; sides 

 rather broadly margined, rotundate-ampliate ; basal mar- 

 gin transversely truncate, obliquely truncate on either side 

 near the hinder angle ; disk shining, impunctate, somewhat 

 swollen, impressed transversely at the base by a deep 

 sulcation, which terminates abruptly on either side just 

 v/ithin the lateral margin. Elytra broader than the 

 thorax, oblong-ovate, moderately convex, rather strongly 

 punctate-striate on the anterior disk, the punctures (which 

 are of equal depth and strength to the apex of the elytra) 

 are arranged in a single row on each stria ; posteriorly 

 they become confused and form irregular double rows; 

 at the apex the striie themselves are confused and entirely 

 lost; interspaces on the outer and hinder disk thickened 

 and convex. 



Longitarsus peruvianus. 



Elongato-ovatus, fulvus, nitidus, capite nigro, antennis 

 (basi flava excepta) scutcllo, pectore abdomineque piceis, 

 pedibus flavis ; thorace lateribus basi rectis, ante medium
