C’oiiper in the LeConte C'ollection, which the lattc'r aulhor 
l)i-iefly characterizes as a little less elonj^ate (than conjinis), 
polished Mack, not bronzed; punctures of elytral rows sti-onyc'i' 
and ccpially densely placed. In his remarks, IwContc' r(‘it('r- 
ates as follows: ‘‘Of the same size as confinU but a little more 
robust and easilj' distinguished by the entire al)senee of bi-onzed 
lustre on the upper surface, even at the suture, and margin.” 
I have carefully examined these two specimens and fiml tlnan 
both to be females and of different species. The one bearing 
the name laliel (in LeConte’s hand) is entirely black above', 
finely alutaceous toward the apex, without trace of bronzi' 
luster, but with the eljdra at the tip slightly tinged with rufous 
as if immature; the specimen is, 1 think, not iierfectly normal. 
The second example is entirely polished and with a very distinct 
narrower bronzed margin to the elytra. LeConte’s character- 
ization is evidently di'awn from the fii'st specimen, but although 
C'ouper’s description neither affirms nor denies the ])resenc(' of 
a bronzed margin, I believe that normal examples will be found 
to possess it, and that in this respect the second specimen will 
prove to be more truly representative of his spc'cies. It is (piite 
impossible with available data and material to determine just 
what C'ouper’s species is. He evidently mixed at least 'wo 
species, possibly more. The first of the two LeC’ontc* sp('ci- 
mens has the lateral elytral stria more closely marginal and 
the ventral surface slightly darker medially: it is likely therc'- 
fore to be an abnormal aquiris or Iccontei. The second LeContc' 
specimen has the lateral elytral stria more remote from tlu' 
margin and may therefore be ventralis, or it may l)e an ('xample 
of a very closely allied species which I hav(' provisionally sc'par- 
ated from ventralis because of a small diffc'rc'uce in tlu' male 
genitalia; the tip of the middle lol)e of the oedc'agus having the 
lateral angles rounded instead of distinct as in th(' true rcnlrahs 
(see figs. 3 and 4 of plate). This form is as likely as any otlu'r 
to be the thing described by C’ouper and rather than I'ch'gatc' 
fraternus to the limbo of unidentified si)eci('s I have chosc'ii to 
use the name for this close ally of venirali-'<. ddu'rc' appear to 
be no characters other than the genitalic' oiu' by which llu'sc' 
two species — if such they are — may be separated.
