Form fl;Uteiicfl ; thorax narrowed in front; elytra truncate at apex, outer 
angle spiniform ; posterior femora pluridentate male, not dentate female; body 
pubescent beneath only, color in the three specimens before me testaceous, with 
metallic gloss; the third joint of antennse twice as long as second ; mesosternum 
as wide as coxa; first ventral segment longer than metasternum. 
Male . — Pygidium short, broadly rounded ; posterior femora strongly incrassated 
with tljree distinct teeth, of which the middle one is much longer and sharper. 
Female . — Pygidium elongate, rounded at apex; posterior femora feebly incras- 
sate, not dentate. 
Length 7 mm. \ .28 inch. Habitat . — Florida. 
I cannot find any description agreeing with the characters of this 
insect. It looks like a small lucida, but differs not only in the sim- 
ple femora of the female, but in the form of the thorax. I have 
seen only three specimens, in the National Museum. 
I>. ciiicticoriiis Newman. Original description translated. 
“Antenme elongate, the basal joint pale, the apical black: vertex shining; 
prothorax quadrate, most minutely punctured, with an impressed dorsal line; 
head and prothorax black seneous, elytra testaceous, shining; elytral apex trun- 
cate; metafemora elongate, incrassate, bidentate; legs testaceous, femora with 
two black vittae. [Corp. long. .325 nnc., lat. .1 unc.] 
This species has been long known as lucida Lac. The synonymy 
was pointed out by Dr. Horn some time ago, [lint. Am. I, p. 9] but 
has not been corrected in the Check List. Lacordaire’s descri[)tion 
of lucida is as follows ; 
“Moderately elongate, above metallic green, very shining, elytra rufe.scent; 
beneath densely cinereo-sericeous ; antennte and legs rufous, maculate with 
black ; protborax transverse, slightly narrowed behind, the angles obtuse but 
distinct, the margin in front and at the middle of the base, reflexed ; towards 
tbe front on each side obsoletely tuberculate; above vaguely rugose, with a 
dorsal sulcus abbreviated behind and an impressed puncture; elytra flattened 
on the disc, declivous at apex, which is squarely truncate; bi-impressed, punctato- 
striate, interstices flat, vaguely transversely rugose. Length 3j — 4i lines; 
width li — Ij lines.” 
Mesosternum as broad as the coxa; first ventral segment longer than the meta- 
sternum; third joint of antennse about equal to the second; posterior femora 
incrassate and dentate. 
Male . — Pygidium truncate; posterior femora strongly incrassate and sharply 
dentate, or even tridentate. 
Female . — Pygidium elongate and rounded at apex; posterior femora feebly 
incras.sate and unidentate. 
The posterior tibiae are serrate in well developed specimens % . 
Length 7 — 11 mm.; .28 — .44 inch. Habitat. — Can., Mich., N. 111., N. H., N. Y., 
Mass., Texas, Vt. 
This is au abundant and very variable species ; it is the species 
called rugifrons Newn. in many collections, which name was applied
