(araplitudine valde rotundata), profunde bisinuato ; elytris 
latius magisque deplanato-impressis, lateribus a basi ad 
apicem sensim angustatis ; corpore subtus pedibusque (tarsis 
exceptis) uniformiter fusco squamosis. 
1. Stenocerus fulvitarsis ^ Germ., Sch. 
2. Stenocerus testudo, Jekel. 
Stirps II. Corpus aut ovato- aut oblongo- subparallelum, latitudine 
saltern duplo longius, majoris mediaeque magnitudinis; 
thorace mediocriter transverso, longitudine inter 7 | et ^ la- 
titudinis, elytris certe angustiore, anterius minus eonvexo, 
haud pulvinato ; lateribus minus conico-ampliato (amplitu- 
dine ante-basali angustius acutiusque rotundata), medio¬ 
criter bisinuato; elytris angustius minusque deplanatis, 
lateribus mox ultra medium subparallelis aut parum angus¬ 
tatis ; corpore subtus pedibusque (tarsis exceptis) aut laete 
aut obscure brunneo tomentosis, sed dilute irroratis aut 
plagiatis.

Stirps III. Corpus ovato-subellipticum, latitudine saltern duplo lon¬ 
gius, mediae minorisque magnitudinis; thorace minus 
transverso, longitudine latitudinis, elytris certe an- 
gustiore,' anterius parum eonvexo, supra longitudinaliter 
evidenter bicanaliculato, carinam medium insigniorem 
emittente; lateribus subrectim conico ampliatis, haud 
sinuatis, lobo postico amplitudinis angulato ; elytris latius 
1 Exceft the frontalis, but the extremely acute production of the pos¬ 
terior carina at the sides, which are straight and conical, distinguish 
it from the first Stirps, of which it has the broadest proportions.
