Male, pygifliuin acutely eiuargiiiate at luiddle; female, simply rounded. 
Length 7 — 9 mm. ; .28— .36 inch. Habitat. — Mich.. Wis.. Mass. 
The sutural margin of the elytra is slightly sinuate in this species 
for a short distance, not exceeding one-tenth the length, near the 
apex. It seems to be rare, and 1 cannot separate it with the si)eci- 
mens before me from torosa Lee. It would be hazardous, however, 
to unite them without a larger series for coni[)arison. 
Var. toi'osa LeConte. Original description translated. 
“ Slightly elongate, blackish violet, head strongly torose: thorax alutaceous, 
sj)ar.sely, finely punctate, somewhat elongate, narrowed behind, angles prominent, 
sides tuberculate, disc suhcanaliculate ; elytra scarcely triangular, apex rounded, 
truncate, the disc rugose, bi-impressed ; posterior femora moderately clavate, 
armed with a moderately acute tooth. Long. .25. Mass.” 
Mesosternum, etc., as in distincta. 
Length 6 — 7 mm.; .24 —.25 inch. Habitat. — Mass., D. C., 111., Iowa. 
I>. Har risii LeConte. Original descriptiefu translated. 
“Elongate, eyes scarcely prominent, orbit absent; elytra convex, apex trun- 
cate, antennae slender, the second joint shorter; aeneous, head scarcely torose, 
thorax elongate, densely rugosely punctate, scarcely narrowed behind, angles 
prominent; slightly canaliculate impressed in front of the base, the lateral tu- 
bercle scarcely prominent, the basal impression well defined. Elytra parallel, 
obliquely narrowed towards the apex, strongly punctured in row's, finely rugose. 
Antennae annulate, the second joint half as long as the others. Long, .42. Pa. 
Very rare. 
“ Male, posterior femora iucrassate, armed with an acute tooth. 
“Female, posterior femora feebly iucrassate, mutic (not dentate). 
“ A singular species, the small eyes suggesting Statira of the Lagriidae.” 
Mesosternum narrow'er than the coxa ; first ventral about equal to the metaster- 
num ; elytral tip truncate. 
Pygidium acutely emarginate male, rounded quite broadly female. The female 
pygidium appears to be emarginate in two specimens, being somewhat elevated 
at middle, probablj" by accident. 
This is the only large species with the sinuate elytral suture. 
Length 10 — 11 mm. ; .40 — .44 inch. Habitat. — Mass., Conn., N. Y. 
D. piisilla Say. Original description. 
“Green, elytra brassy, tibiae and tarsi rufous, second and third joints of an- 
tennae equal. Head brassy green, very densely and couflueutly punctured, a 
well impressed frontal line, lateral lines none, no a])pearance of frontal tnl>ercles; 
antennae short, much less than half the length of the body, .second and third 
joints equal, fourth hardly longer, joints dull rufous, blackish at tip. Thorax 
green, tinged with brassy, longer than broad, as densely punctured as head, mid- 
dle and anterior edge a little elevated, longitudinal line none, lateral tubercles 
obvious. Elytra brassy green, a little tinged with cupreous, with striae of punc- 
tures, three longitudinal indentations near the suture, of which the anterior one 
is widest and deepest, with a slight impressed line extending obliquely to the 
base, tip decu'rved and rounded. Beneath green, tinged with brassy, feet rufous, 
thighs at tip brassy green, posterior pair with a prominent angle beneath. 
Length rather more than i inch.” 
This species has been known as eiiprea Kirby, from which it does 
not differ. I subjoin Kirby’s description also:
