The type is quite distinct in coloration, the oval oblique pale 

 spots at the elytral apex being well defined. This maculation 

 probabl}' becomes gradually obsolete, however, in a large series.

A very small and convex, suboval species, varying in color from 

 black to dark brownish-testaceous, easily recognizable by its 

 small and convex eyes, which are at a great distance from the 

 base, the small prothorax, narrowly suboval el^'tra, with the 

 humeri only moderately exposed and somewhat rounded at base. 

 Length 1.15-1.85 mm. ; width 0.6 mm. 



This species, which has been carefull}^ described by LaFerte, is 

 widespread in distribution, the series in my cabinet being from 

 Kansas, Lake Superior, North Carolina and Pennsylvania ; it is 

 recorded b}' LeConte also from Boston, Mass. There can be no 

 doubt whatever of the synonymy proposed above. 



57. A. ictericus Laf. — Mon., p. 149. 



Somewhat narrowly convex, pale ochreo-flavate and moderately 

 shining throughout; pubescence moderatel}^ long, subdecumbent, 

 coarse and not dense. Head wider than long, broadly, trans- 

 versely truncate at base ; eyes very small, extremel}' convex and 

 prominent, the tempora swollen, rounded, much larger than the 

 eyes and fully as prominent ; punctures fine, rather close-set ; 

 antennae not as long as the head and prothorax, stouter toward 

 apex, especially the last three joints. Prothorax not quite 

 as wide as the head, wider than long, prominent and subangulate 

 laterally near the apex, the sides thence strongly oblique and 

 feebly sinuate to the base ; apex broadly, circularh- arcuate ; punc- 

 tures fine, deep and rather dense. Elytra not more than two- 

 thirds longer than wide, very nearly twice as wide as the 

 prothorax, circularly rounded at apex, the humeri moderately 

 exposed at base; sides parallel, feebly but distinctly arcuate; 

 punctures rather fine but strong, close-set. Abdomen shining, 

 punctulate, the legs slender. Length 1.7 mm.; width 0.6 mm. 



Florida. The male sexual characters are somewhat feeble; the 

 copulatory sheath is ver}^ broadly and circularly rounded at apex, 

 longitudinally impressed along the middle dorsalh', and broadly 

 excavated beneath. LaFerte's measurements appear to be care-
