306 MEMOIRS ON THE COLEOPTERA 



areas, behind the oblique fascia; femora strongly clavate. Length (9) 

 10.0 mm.; width 4.1 mm. Florida (Lake Worth). 



I do not know of any species closely allied to this; in general 

 ornamentation it is somewhat as in planidorsus, but is much nar- 

 rower and with more anterior position of the oblique fasciae. 



Leptostylus crescenticus n. sp. Similar to the preceding in coloration 

 and vestiture, but the body is narrower in form, the front quadrate, the pro- 

 thorax more narrowed apically than basally and with only three tubercles, 

 the outer posterior being obsolete; the elytra are similar but with the 

 sparse punctures rather coarser, the arcuately oblique pale fasciae more 

 posterior and not margined behind with darker tint. Length (9) 

 8.6 mm.; width 3.4 mm. Florida (Crescent City), Schwarz. 



For many years the type of this species has been in my collection 

 under the name collaris Hald., but on reading the original descrip- 

 tion of collaris, I find the two do not agree in any important par- 

 ticular. The elytral truncatures are as sharply marked as in 

 lecontei. 



Leptostylus taeniatus n. sp. Stout, oblong, convex, blackish-piceous, 

 the minute dense and coarse vestiture cinereous, with small fulvous 

 clusters of more erect hairs sparsely intermingled on the elytra, limited 

 by a straight transverse even and densely white entire fascia at the 

 summit of the declivity, the posterior parts like the anterior; front dark, 

 a small yellowish spot at the centre; antennae slender, barely longer 

 than the body (o 71 ), a little shorter (9 ), the joints to the fifth strongly 

 mottled brown and white, those beyond cinereous, all the joints black 

 at tip; prothorax one-half wider than long, carinate medially and with 

 a short oblique elevation at each side of the middle anteriorly, the sides 

 obtusely tumid at the middle; vestiture concealing the sculpture, except 

 an even transverse subbasal line of punctures; elytra parallel, rapidly 

 oblique and moderately declivous behind, two-fifths wider than the pro- 

 thorax, the tips narrowly arcuato-truncate, without sharp angles; two 

 discal ridges uneven, distinct, fasciculato-spinulose, the outer bent 

 outwardly near the base; punctures coarse, rather close but filled with 

 the vestiture; femora clavate; tarsi rather short and slender throughout, 

 the basal joint of the posterior not twice as long as wide. Length (o 71 9 ) 

 8.4-10.8 mm.; width 3.6-4.5 mm. Florida (Lake Worth), Kinzel. 



Very distinct from any other of our known species, but its rela- 

 tionship with Cuban species cannot be stated at present; it was 

 sent in considerable number. 



Leptostylus divisus n. sp. Narrower, more elongate and less convex, 

 parallel, clothed densely with rather dark cinereous vestiture, becoming 

 brown on the elytra behind an even posteriorly arcuate transverse line 

 near posterior fourth, the coloration, sculpture and vestiture throughout
