Nautes ovatus, n. sp. 



Length. 4£ lines. — Ovate, convex ; shining ; of a rich, purplish-brown with, 

 slight green and purplish-coppery reflections ; epistoma broadly emarginate ante- 

 riorly j faintly separated from the front, and — together with the latter — rather 

 densely punctured : prothorax somewhat closely punctured, the punctures more 

 scattered on the disc ; lateral margins thickened ; broadly lobed at the middle of 

 the base, the angles moderately prominent : scutellum punctured at the sides : 

 elytra deeply striated, the striaa faintly punctured, or nicked at the sides ; intervals 

 sub-convex, sparingly punctured : under-side shining reddish-brown, the legs a 

 little darker : metasternum with a few punctures at the sides : abdomen strongly 

 longitudinally wrinkled. 



Hab. " Colombia." 



The above description applies to a specimen (labelled " Nautes 

 ovatus, Dej., nov. g., Colombia ") formerly in tbe collection of Dejean ; 

 Nautes being one of tbe new genera proposed by bim since the publi- 

 cation of his last catalogue ; another example (both form part of the 

 collect. Laferte) is a trifle more bulky — 4£ lines ; a little duller in 

 colour, the green, &c, reflections being less apparent ; the punctuation 

 on the prothorax finer ; and the legs and antennae a shade redder. 



Nautes elegans, n. sp. 



Length 2| lines. — Elongate oval ; but little convex ; entirely of a glossy dark 

 brown with a slight golden tinge ; head rugosely punctured, epistoma broadly 

 emarginate anteriorly, confounded with the front : prothorax rather closely — save 

 on the disc — punctured ; the sides moderately margined and but little thickened 

 at the edges ; the fore angles produced ; the base moderately bisinuate, lobed in 

 the middle, having the usual basal foveas, and another, fainter and oblong, between 

 them and exactly in the middle of the base : scutellum slightly punctured at the 

 sides : elytra but little convex, more gradually attenuated behind than in the 

 preceding species ; deeply striated, the striee finely and remotely punctured, or 

 nicked at the sides ; the intervals sub-convex at the sides and apex, flat on the 

 middle, slightly and transversely rugulose : under-side, legs, &c, shining reddish- 

 brown. 



This species forms part of the coll. Laferte ; it stands labelled 

 "Nautes elegans, mihi, col. Dupont," but, unfortunately, no clue is 

 given as to its habitat. 



.Nautes eximius, n. sp. 



Length 3^-3| lines. — Oblong ; convex ; head and prothorax slightly rugged, of 

 a coppery-brown variegated with patches of vivid green, somewhat iridescent ; 

 epistoma squarely truncated anteriorly, separated from the front by a broad, well- 

 marked, lunate impression ; head rather coarsely punctured, especially between the 

 eyes : prothorax punctured, the punctures larger and more crowded at the sides ;
