226 AMERICAN COLEOPTERA. 



PARNID^E. 



Elniis pecoseiisis n. sp.— Elongate-ovate, distinctly wider behind, black, 

 shining, with very faint violaceous lustre, tarsi pale. Antennse entirely testa- 

 ceous, last three joints equal in length to thesis preceding. Prothorax wider 

 than long, sides convergent from the basal angles, before which they aie faintly 

 sinuate, broadly rounded at basal third, thence more strongly convergent to the 

 acute apical angles; disk evenly feebly convex without median channel, moder- 

 ately strongly punctured, the punctures separated by their own diameters or 

 slightly more; basal plica parallel with the margin and nearly attaining the 

 middle ; sides exterior to the plica subrugose. Elytra slightly more than one-half 

 longer than wide, at base very little wider than the prothorax, humeri small but 

 evident, sides diverging to apical two-fifths, striai distinctly though not deeply 

 impressed, punctures rather strong; interstices feebly convex, evidently but 

 sparsely irregularly punctate. Beneath rufopiceous, densely ochreo-cinereous, 

 sericeous pubescent. Length 2.5 mm.; width 1.1 mm. 



Pec(ts. One example (Cockerell). 



Of the described species this is apparently nearest to corpulentus 

 Lee. The latter from the description is of stouter build, greenish- 

 black, the prothorax scarcely punctate and feebly channeled, the 

 antennae blackish at tip, legs testaceous. All other species allied to 

 the present one have the elytra maculate, except divergens, which is 

 distinctly different by its more parallel form and greenish-black color. 



The maculation of the elytra is probably not entirely constant, at 

 least one example thus marked is associated with the otherwise uni- 

 formly colored corpulentun. 



Elniis addfndus n. sp.— Moderately stout, subovate, black, shining, 

 scarcely at all pubescent. Antennae testaceous, last joint becoming piceous at 

 apes; ninth similar to the eighth and scarcely larger; eleventh as long as the 

 two preceding united and just visibly wider. Prothorax distinctly transverse, 

 sides nearly parallel in basal third, faintly sinuate before the hind angles, broadly 

 rounded and convergent anteriorly; lateral elevated line extending from base to 

 apex, disk between the carinse finely punctate, feebly transversely impressed 

 before the middle, punctures distant from two to three times their own diame- 

 ters; spaces between the carinae and side margin opaque, punctures not defined, 

 an oblique carina extending forward from the hind angles for about two-fifths 

 the thoracic length. Elytra wider behind, striae evidently imi)ressed and rather 

 strongly punctured, intervals minutely sparsely punctulate. Lower surface 

 paler, pubescent and finely punctate as usual; legs rufous. Length 2.25 mm.; 

 width 1.2 mm. 



Pecos. Two examples (Cockerell). 



The tips of the humeral umbones are dull rufous in one example, 

 but it is not likely that the elytra ever become truly maculate. 



From the described species having entire thoracic carinse and 

 shinino- surface, the present differs in the absence of lateral elevated 

 lines on the elytra. It should precede glaher on our lists.
