marked in all the feeble striae. Length (9) 8.6-8.8 mm.; width 

 3.3-3.4 mm. Alabama (Mobile). Two almost perfectly similar 

 specimens nanula Csy. 



Anterior tarsi ( 9 ) not so equally slender throughout, the two basal 

 joints notably wider and strongly as^^mmetric, acutely produced 

 internally at apex. Body not so small and rather more elongate, 

 convex, polished black, the legs obscure rufous; head a little larger, 

 the anterior impressions similarly deep, remotely separated and 

 diverging; mandibles a little longer, thick; maxillary palpi similarly 

 dark rufous but stouter, especially the thick fusiform fourth joint; 

 prothorax not so short, two-fifths wider than long, otherwise nearly 

 similar, except that the subapical incised transverse line is more 

 arcuate and, medially, more distant from the apical margin, the 

 base narrower, not half the maximum width, and the subbasal 

 marginal denticle small and very feeble and at a greater distance 

 from the base, the sides from denticle to base more evenly con- 

 tinuing the curvature of the posterior part of the sides; elytra 

 nearly similar in outline, a fifth wider than the prothorax and but 

 slightly more than twice as long, the striae more widely, very feebly 

 impressed and with punctures evident throughout the width but 

 feebler and almost completely disappearing under certain angles of 

 view. Length (9 ) lo.o mm.; width 3.45 mm. Alabama (Mobile). 

 One example simiola n. sp. 



3 — Male more parallel, convex, polished and very smooth, rufo-castane- 

 ous in color; head nearly as in the preceding species and with simi- 

 larly thick antennae; anterior impressions more nearly parallel; 

 prothorax of nearly similar outline but only a third wider than long, 

 the sides subparallel, rapidly rounding at apex, converging basally, 

 the subbasal denticle at some distance from the base and almost 

 completely obsolete, the foveae, anterior incised line and median 

 stria as usual; elytra of thq^same outline, fully one-half longer than 

 wide, but not evidently wider than the prothorax; surface with 

 vestiges of feebly impressed smooth striae at certain angles of view; 

 anterior tarsi very moderately dilated, convex above, the joints 

 virtually symmetric. Female more abbreviated than the male but 

 otherwise nearly similar, the anterior cephalic impressions more 

 strongly diverging as in the preceding species, the prothorax shorter, 

 with the posterior denticle strong, prominent and relatively nearer 

 the base; anterior tarsi more slender but with the first three joints 

 strongly and obliquely produced and acute internally at apex; 

 elytra more distinctly wider than the prothorax than in the male; 

 maxillary palpi with the fourth joint not very stout, gradually 

 narrowed in apical half, the apex narrowly truncate. Length 

 (cf 9 ) 9.0-9.2 mm.; width 2.85-3.0 mm. Alabama (Mobile). 

 Two examples castigata n. sp. 



Female still more abbreviated than in the preceding, also with relatively 

 smaller head and prothorax and more rapidly rounded elytral 

 humeri, deep polished black, the legs rufo-piceous, the mandibles 

 smaller, as usual with a few oblique strigae; cephalic impressed 

 lines very moderately diverging; last palpal joint more pointed at
