with their pubescence all whitish except the reddish inner tarsal tufts, the 
basal joint of hind tarsi three and one-third times as long as wide, mid- 
dle joints about one-half as wide as long. Anterior coxae not distinctly 
spined. Tibial spurs long and yellowish, not pectinate. Claws rufous with 
a large submedian tooth. Abdomen neatly conical, very polished, two basal 
segments smooth and practically impunctate, following segments less pol- 
ished and finely, indistinctly punctured: Apical margins .of segments not 
depressed, 1 with a narrow fascia reduced to a mere line medially. and par- 
alleled by a very thin fascia on base of 2, apical margins of 2-5 with broad 
fasciae, all pure white, continued as strong apical fringes ventrally. Disks 
of segments 4-6 with scattered black bristles. 
dS. Length 10 mm. Differs from the 2 as follows: Pubescence denser 
and more tinged with yellowish, the clypeus covered by long, pale yellow- 
ish hair, the thoracic dorsum pale yellowish gray mixed with a few black 
hairs on scutellum; malar space three-fifths as long as broad; antennal 
joint 3 distinctly shorter than 4 and twice as long as 2, 2+3=4, the pro- 
portion being 2:4:6; flagellar joints one and two-fifths as long as broad; 
mesothorax more finely and sparsely punctured, these not crowded, even 
anteriorly, scutellum with very large, coarse punctures; bow! of metathorax 
with a few short lateral ridges; basal joint of hind tarsi five times as long 
as wide, middle joints one-half as wide as long; apical tarsal joint rufes+ 
cent; abdominal segments 1-5 with narrow, white, apical fasciae, segment 
1 more distinctly punctured and with long pale ochraceous hair on the disk. 
Genitalia—Stipes notched, its apical joint slender and sparsely haired; 
sagittal’ rods basally much dilated, becoming abruptly very slender medially 
and converging distally, the wings hood-shaped; volsella large, about one- 
half the length of sagitta; seventh ventral plate elongated latero-apically, 
the outer prolongations recurved, the inner ones overlapping, the whole of 
the apical lobes finely haired, thinnest medially. (Plate 2, figures 8 and 
8a.) 
Type LocaLity.—Georgia; type in collection of American En- 
tomological Society. 
This handsome species was described by Mr. Cresson from a 
single male specimen collected by Mr. James Ridings in Georgia. 
Mr. Charles Robertson recognized the species from Florida spec- 
imens, and described the female in 1895. The above description 
is drawn from a pair very kindly sent by Mr. Robertson, taken at 
Inverness, Florida, March 19, 1891, by himself. I have also a 
single female collected in Orange county, Florida, by Mr. F. 
Rauterberg. There is nothing in Smith’s description of C. nitidus 
to indicate specific distinctness from the present species, and I
