Triclinltica Thammi. 



Ovata, convexa, rufo-fulva, nitida, oculis, aiitennis (Lasi 

 picea excepta), abdomine, elytrorum dimidio postico, 

 femoribus anticis quatuor apice, posticis fere totis, tibiis 

 tarsisque nigris ; thorace Irevi, basi profunde transversim 

 sulcato ; elytrls pube suberecta grisea vestitis, fortiter 

 punctato-striatis ; interspatiis couvexls, ad latera sub- 

 costatis. 



Long. 2^ lin. 



Hab. — Peru. 



Head trigonate; encarpaj Avell defined, contiguous, sub- 

 rotundate ; carina raised, linear; antennas nearly equal to 

 tlie body in length, filiform, the three lower joints piceous, 

 the rest black. Thorax nearly tAvice as broad as long ; 

 sides straight and very slightly diverging from the base 

 to the middle, thence obliquely converging and slightly 

 rounded to the apex ; the anterior angles thickened, 

 obliquely truncate, the hinder ones produced into a short 

 acute tooth ; disk convex, smooth and shining, impressed 

 just in front of the basal margin with a deep transverse 

 groove, which abruptly terminates on either side, some 

 distance within the lateral margin. Elyti-a broader than 

 the thorax, convex, clothed with rather coarse, long, sub- 

 erect griseous haii'S ; each elytron with ten rows of deep 

 punctures, the first short ; interspaces on the inner half of 

 the anterior disk subconvex, distinctly convex on the 

 hinder disk, those on the outer disk more strongly raised 

 and subcostate. 



So nearly allied in form and coloration to Eugonia 

 dimidiatipennis , that for a time I placed it with that 

 species. 



Genus Stegnea. 



Corpus ovatum, convexum. Caput exsertum ; encarpis 

 contiguis ; carina elevata ; antennis filiformibus ; oculis 

 integris; palpis maxillaribus articulo ultimo conico, 

 acuto. Thorax transversus, margine basali leviter lobato ; 

 disco ad basin sulco profundo, utrinque longe intra mar- 

 ginera lateralem desinente, impresso. Elijtra modice 

 convexa, infra basin nou depressa, punctato-striata. Pedes 

 mediocres ; coxis anticis ovatis, non elevatis ; femoribus 

 posticis incrassatis ; tibiis anticis quatuor apice muticis ; 

 tarsorum posticorum articulo basali sequentibus tribus 

 aiquilongo ; uiiguicidis appendiculatis. Prosternum ad
