They correspond closely with Mr. SchaefTer's description with 

 one exception: the antennal funicle has six instead of seven 

 joints. A single example from the Huachucha Mountains, 

 Arizona, shows the same structure. 



Aulobaris elongatus new species. 



Elongate-oval, shining, black throughout. Head finely punctulate. 

 Beak a little shorter than head and thorax, regularly arcuate, finely punc- 

 tured, coarsely at the sides below antennal insertion. Second joint of 

 funicle one-half as long as the first, scarcely as long as the two following 

 joints together; joints three and four, slightly longer than wide, five and 

 six shorter and quadrate, seven transverse; club as long as four preceding 

 joints. 



Prothorax one-sixth wider than long, the apical constriction almost 

 obsolete; apex one-half the basal width; sides nearly straight and feebly 

 converging from basal angles to middle, thence strongly arcuate to apex. 

 Disk of thorax with coarse, deep, rounded punctures separated by their 

 own diameters or less and becoming obliquely confluent at the sides; 

 median impunctate line not distinct; basal lobe very small. Scutellum 

 coarsely punctured. Prosternal groove normal, the sides not produced 

 inwardly before the coxae. 



Elytra three-fourths longer than thorax, widest at the humeri where 

 they are slightly wider than the thorax; sides straight and feebly con- 

 verging two-thirds to apex; disk moderately striate, intervals three to 

 five times as wide as the grooves, each with a single fairly regular series 

 of coarse rounded punctures but little smaller than those of the thorax. 

 Length 3.5 to 4.1 mm. 



Three specimens, Macdona, Texas, July 29. Elongatus 

 would be placed near ibis in a synoptic arrangement of our 

 species. The latter is easily separated by the distinct sub- 

 apical constriction and the much finer elytral punctures. 



Centrinus falsus Lee. 



I have taken two specimens of this species at Mauch Chunk, 

 Pennsylvania, August 10, which agree in every respect with 

 the form so named in the Horn collection. My specimens 

 are both males and have the antennal formation of Odonto- 

 corynus, namely the enlarged and concave apical funicular 

 joints and the polished basal area of the club provided with 

 a dentiform process. On each side of the prothorax im- 

 mediately behind the apical margin there is a small polished 

 tubercle. This character is unique among our species of
