superam scrobis directis et approximatis, ibique saspe con- 
junctis, quarurn infera continuationem superam scrobis 
marginat, tertiaque magis distante, infera, prolongationi 
scrobis parallela ; demum carinis basi rostri supra lateribusque 
simul novem; scrobe obliqua, elongata, basi subcirculari, 
cavernosa, dein sublineari, infra usque prope basin rostri 
ducta, raro subinterrupta. Pedes breviusculi : femoribus 
posticis apicem segmenti tertii abdominis non attingentibus. 
—Ptychoderes , Sch. 
B. Rostrum elongatum, basi valde angustatum, latitudine basali 
subtriplo longius, lateribus versus apicem valde ampliatis; 
medio disci unice, supra lateribus utrinque bicarinato, ca¬ 
rinis elevatis, duobus lateralibus approximatis, una vero, 
altera intra-marginali, secundum lateribus rostri flexuose 
excurrentibus, antice cum oppositis divergentibus, latera 
apicis attingentibus ; lateribus inflexis carina tertia duabus 
supra-lateralibus parallela; demum carinis basi rostri simul 
septem ; scrobe antennali parum elongata, infra medium 
rostri baud superante, basi subcirculari, cavernosa, dein 
lineari, obliqua, leviter impressa, plus minusve interrupta et 
obsoleta. Pedes longiusculi: femoribus posticis medium 
segmenti quarti abdominis superantibus. — Hypselotropis , 
Jekel. 
II. Rostrum lateribus ab oculo ad scrobem antennarum subteres, nullo 
modo carinatum, interdum subimpressum, aut rugulosum aut sub- 
lseve; scrobe subcirculari, brevi, infra raro per impressionem inter- 
ruptam laevem oblique continuata.— Tribotropis , Jekel. 
Thus the genus Phlceotragus remains quite homogeneous, and the 
formerly misplaced American species are arranged near the Ptychoderi of 
Schonherr, and become types of two new genera. As may have been ob¬ 
served in the preceding characters, there is in these species a more or less 
distinct continuation of the groove beneath, and by them we are naturally 
led to the Phlceotragi and other elongate genera, in which the groove is 
only circular or ovate, without any appearance of continuation beneath.
