320 Mr. J. S. Baly's descriptions of new genera 



raised, oblique, linear, separated by the apex of the carina, 

 the latter raised, oblong; lower portion of clypeus and 

 labrura piceous ; antenna three-fourths the length of the 

 body, robust, obscure fulvous, three outer joints black ; 

 second and third joints equal in length, the fourth rather 

 longer than the third. Thorax more than twice as broad 

 as long ; sides straight, quickly converging from base to 

 apex, anterior angles oblique, thickened ; basal margin 

 bisinuate on either side, the medial lobe obtusely rounded ; 

 upper surface finely and rather closely punctured. Scu- 

 tellum semirotundate. Elytra broader than the thorax, 

 minutely and rather distantly punctured. Hinder tibia 

 equal in length to the femur, compressed at the base, 

 strongly thickened towards the apex, its upper surface 

 flattened, slightly concave near the apex; basal joint of 

 hinder tarsus dilated, subtrigonate. $ . 



Euplectroscelis himaculata. 



Rotundato-ovata, convexa, nitida, pallide rufo-picea, 

 antennis, pedibus anticis quatuor tarsisque posticis obscure 

 fulvis; vertice femoribusque posticis piceis ; thorace minute 

 punctato ; elytris minute punctatis, nigro-piceis, utrisque 

 plaga rotundata prope medium posita rufa. 



Long. 1^ lin. Hub. — Brazil, Parana. 



Head trigonate, not longer than broad ; vertex and 

 fi-ont slightly swollen, smooth, impunctate ; encarpge obso- 

 lete ; carina strongly raised, linear ; eyes large, ovate- 

 rotundate ; antennae four-fifths the length of the body, 

 filiform, apex of terminal joint emarginate. Thorax three 

 times as broad as long ; sides nearly straight, converging 

 from base to apex, anterior angles obliquely truncate, 

 thickened ; basal margin bisinuate on either side, the 

 medial lobe very obtusely rounded ; upper surface finely 

 punctured. Elytra finely punctured, the interspaces 

 (when seen under a strong lens) covered with very fine 

 irregular strigee ; hinder tibi^ robust. 



Euplectroscelis placida. 



Late ovata, convexa, pallide picea, nitida, pedibus an- 

 tennisque fulvis, femoribus tibiisque posticis pallide piceis ; 

 vertice impunctato, obscuriori ; thorace sat tenuiter punc-
