It will be noted how poorly the genus Harpalus, so commonly found in 
more northern regions, is represented in Florida. The reverse will be found 
in the following genus, which both in species and individuals, seems to abound, 
forming a characteristic featurs of every Florida collection, at least from the 
southerly part of the state. 
The genus Hemisopalus Casey (type Selenophorus opalinus Lec.) differs. 
from Selenophorus by the more or less depressed dorsal surface, by the very 
slender hind tarsi, nearly as long as the tibiz, and other characters, including 
the frequently opalescent elytra; it includes.of previously described Flori- 
dian species, opalinus, gagatinus, wripennis and subtinctus, besides the follow- 
ing described by Casey as new, viz.: (1) delumbis Csy, Lake Worth, said to 
be allied to subtinctus which Casey did not have for comparison; (2) depres- 
sulus Csy, Lake Worth, said to be closely allied to iripennis, not repre- 
sented in Casey’s collection; (8) vigilans Csy, Florida, placed next to 
depressulus. As in some other instances, the description of these species 
as new seems to result from Col. Casey’s inability to make the characters 
observed in Floridian specimens coincide with those described from more 
northern specimens; he does not record as Floridian the species given below 
his own species apparently replacing them, rather than constituting addi- 
tions to the list. It may therefore be eventually necessary to use his names 
in place of those we have cited, perhaps in varietal or trinomial form, but 
not probably as pure additions to the list. 
Selenophorus palliatus Fabricius (including S. stigmosus Leconte, 
treated as a synonym in Horn’s revision of the genus). Enterprise, St. 
Augustine, Lake Worth, Buck Key, not rare, frequently attracted by the 
light (Schwarz); Biscayne Bay (Slosson Coll., January-March); Lake 
City (Agl. Exp. Sta.); Sanford, Jan. 13, one only, beneath board in field 
(Blatchley); Lakeland, Nov. 7 (Davis); Everglade, May, July (one only)

allied, apparently unnamed form, extends to Lower California. Common 
in Mobile Co., Ala. (Léding). 
Selenophorus chokoloskei n. sp. 
Piceous, legs pale, upper surface shining, bronzed. Thorax equally wide at base 
and apex, sides regularly arcuate, widest a little before the middle, hind angles 
distinct but obtuse and rounded, basal impressions almost obsolete. Elytra a little
