inhabiting exclusively the southern Atlantic states, may be dis- 

 tinguished as follows: 



Elytra narrowly and obliquely sinuato-truncate at tip, the exterior angle 

 very obtuse and blunt, the sutural slightly produced and acute.. .2 



Elytra not truncate at tip, rounding regularly to the sutural angle, which 

 is acute but not at all spiniform 3 



Body larger and a little stouter, slender, parallel, subdepressed, deep 

 black, the tibiae, tarsi and antennas picescent; lustre dull, the elytra 

 alutaceous; eyes separated by evidently less than their width, the 

 head and prothorax very finely, densely punctate, a narrow median 

 line impunctate: antennae (cf) about a fifth longer than the body, 

 joints 3-6 abruptly much thicker than the very slender and filiform 

 outer part, smooth and shining, with merely a few long erect hairs, 

 the fourth joint four-fifths as long as the equal fifth or sixth and 

 three-fourths as long as the third; prothorax fully two-fifths longer 

 than wide, the sides parallel and straight anteriorly, gradually very 

 feebly arcuato-convergent posteriorly to the feeble subbasal con- 

 striction, the median line slightly tumid just behind the centre, the 

 sparse hairs decumbent and very minute; elytra a little more than 

 three times as long as wide, two-fifths wider than the prothorax, 

 minutely, closely sculptured and with some small sparse subasperate 

 punctures, generally lineate in arrangement and bearing short, stiff 

 and very inconspicuous fulvous hairs. Length (cf) H-5 mm.; 

 width 1.9 mm. Florida ebenus Newrru 



Similar to the preceding but much smaller and more slender, dark piceous- 

 brown in color, alutaceous, the sculpture throughout nearly similar; 

 eyes less widely separated; antennae similar but only slightly longer 

 than the body, the third joint relatively thicker, the fourth shorter, 

 only three-fourths as long as the fifth and two-thirds as long as the 

 third; prothorax not quite so elongate, otherwise similar, except 

 that the basal constriction is deeper and less obtuse and the median 

 line faintly tumescent from behind the middle nearly to the apex; 

 elytra similar throughout but relatively a little narrower, only about 

 a third wider than the prothorax. Length (cf) 9.0-9.3 mm.; width 

 1.5-1.6 mm. Florida (Biscayne Bay), Schwarz. 



floridanus n. sp. 



3 Similar to ebenus but much smaller, more slender and blackish-brown, 

 the antennae (c?) distinctly longer than the body, the joints similarly 

 proportioned but not so elongate, the head and prothorax similarly 

 sculptured; prothorax similarly elongate but with the sides broadly 

 and feebly arcuate, converging slightly anteriorly and posteriorly 

 to the similar subbasal constriction, the median line broad and flat 

 behind the centre, without trace of tumidity; elytra similar though 

 a little more shining, more finely sculptured and punctate and 

 relatively narrower, only about a fourth wider than the prothorax, 

 the sparse prostrate hairs similarly minute, the erect hairs nearly 

 similar. Length (cf,9) 7-7-9-3 mm.; width 1.3-1.5 mm. North 

 Carolina (Southern Pines), Manee exilissimus n. sp.
