are in my collection. Other localities are Sanford and Jacksonville 

 (Mr. Genung) and Tampa, Florida (U. S. Natl. Mus. Coll.). 



This is quite a distinct species, smaller than either tnmidus or 

 concolor, and easily distinguished from Icicisii and borealis by both 

 color and punctuation. It has no thoracic impression, or plica, as 

 have all the species in the nificollis group, except borealis. The upper 

 surface is exceptionally polished, and the extent of the very dark 

 markings give it an almost black appearance. 



Haliplus annulatus new species. 



Oval, very small, rufous. 



Size: length 2—2]/2 mm.; width ikj-iM mm. 



Head very finely, not deeply, punctured ; eyes large ; antennae color 

 of head. 



Pronotum finely, densely punctured, scarcely less so on disc, impressed 

 at base, slightly infuscate along the apical margin. 



Elytra widest at about the middle, sides gradually rounded, apices 

 rounded exteriorly and very feebly oblique to the sutural angle, which is 

 rectangular ; punctures of the strias small, not deep, largest at the sides and 

 gradually smaller to the sutural stria, but not strongly diminishing apically ; 

 punctures of the interspaces very minute, scarcely discernible ; the markings 

 consist of bars or bands of black placed on base, across the middle and at 

 apex, of which the basal is narrowest, but not linear, the others broad and all 

 extending nearly, if not quite, across the elytra from side margin to side 

 margin, the middle being the most irregular of the three in outline. 



Under surface rufous. 



Prosternal ridge narrowest at base, gradually broadening to apex, sides 

 and apex distinctly margined, slightly convex basally with a few scattered 

 punctures. 



Mid-metasternum narrowly impressed each side at base of side margins ; 

 side margins fine and nearly reaching the suture of antecoxal piece. 



Hind coxal plates with fine, not deeply impressed, punctures which are 

 coarser towards the apices ; apices separately rounded, but with the sutural 

 angle very sharp, almost produced. 



Abdoijiinal segments with the usual rows of punctures very fine. 



Male tarsi thickened, slightly pedunculate, and with the claws noticeably 

 long for so small a species. 



Male and female types from Taylor Co., Florida (W. S. Genung), 

 in my collection. 



Distinct froin any other species on account of its small size and 

 peculiar markings. About one hundred and fifty specimens examined 

 show very little variation, and the largest is not larger than the 

 smallest specimen of Icwisii. T have seen other localities from which
