ELEODES GRACILIS van DISTANS, new variety. 



Elongate ovate or oval, slightly robust, integuments firm, glabrous 

 and shining; elytra with distant stria? of very sharply defined j)unc- 

 tures. 



Head about twice as wide as long, feebly and quite evenly convex, 

 broadly and. slightly impressed laterally, frontal suture not generally 

 evident, finely, rather sparsely and somewhat evenly punctate, slightly 

 more densely so laterally. Antenn(B rather long, attaining a short 

 distance be3''ond the prothoracic base, feebly compressed and a little 

 incrassate in outer four joints, third joint about equal to the next two 

 taken together, the fourth a little longer than the fifth, the latter to 

 the eighth inclusive subequal in length, eighth about as wide as long 

 and triangular, ninth and tenth feebly transversely oval, eleventh 

 short and subtrapezoidal or ovate. 



Pronotiiin widest at about the middle and about one-fifth wider 

 than long; disc moderately and quite evenly convex, more or less 

 declivous at the aj)ical angles, polished and shining, rarely subalu- 

 taceous, very finely and sparsely punctulate. laterally in anterior 

 four-fifths narrowly and feebl}^ impressed, impressed area subopaque 

 and more or less obsoletely granulato-rugulose ; apex feebly and 

 broadly emarginate, rather coarsely beaded laterally, obsoletely so at 

 the middle; i^ides broadly, evenly, and not strongly arcuate in ante- 

 rior three-fourths, thence to base less arcuate, straight or scarcely 

 subsinuate, rather coarsely beaded; base broadly and slightly arcu- 

 ate, coarsely beaded, about one-fourth wider than the apex and equal 

 to the length; apical angles acute, not large, subdentiform and fre- 

 quently slightly everted ; basal angles obtuse, distinct, and not 

 rounded. 



Projdewrce smooth and opaque, veiy sparsely and obsoletely punc- 

 tulate, more or less rugulose. 



Elytra oval, widest at the middle, polished and shining; hase 

 broadly, feebly, and distinctl}^ emarginate, very slightly wider than 

 the contiguous prothoracic base; humeri obtuse, distinct, and not 

 prominent; sides evenly arcuate, somewhat gradually narrowed pos- 

 teriorly, apex obtusely rounded ; disc more or less moderately convex, 

 rarely slightly flattened on the dorsum, evenly and broadly rounded 

 lateralW, arcuately but not suddenly declivous behind; surface 

 striato-punctate, striae distant and not impressed, regular and usually 

 very distinct, punctures distinctly defined, those of the stria:> close 

 and separated by a distance equal to their diameters, moderately small, 

 intervals flat Avitli a series of very fine and distantly spaced minute 

 punctules; punctures simpl(\ but somewhat feebly submuricate on
