purascenti-nigris, basi, sutura et lateribus usque medium anguste

TETANOLA. 
Corpus elongatum, postice gradatim acuminatum, sparsim setosum, 
vittis nudis politis. Caput (cum oculis) thorace ¢ 2 haud latius, 
inter antennas depressum, fronte modice elongata, quadrata, infra 
retracta. Thorax cylindricus, prope basin paullulum contractus. 
Elytra valde elongata, postice acuminata, apice fere acuta, dorso 
planata, sparsim tenuiter lineato-punctata, carina laterali recta, 
obtusa, usque ad apicem continuata. Antenne <6 2 corpore 
breviores, sparsim ciliate. 
The acuminate elytra and extension of the lateral carina 
(although as an obtuse ridge only) to the apex constitute the 
chief characters of this genus. The smooth and shining 
integumental stripes of the upper surface are also a peculiarity 
which distinguishes it from the Amphionyche. 
Tetanola polita. 
Subtus fulva, tenuiter pubescens, lateribus nigro-fuscis ; supra nigro- 
vel fusco-castanea, elytrorum basin versus rufo-castanea, polita, 
capite, vitta laterali prothoracis, elytrorum lineis tribus (suturali 
et laterali ad apicem conjunctis, interiore ante apicem desinente) 
flavis ; thorace tomentoso, disco postice tuberculo polito; antennis 
cinereo-fuscis, scapo fulvo-nitido ; pedibus fulvis, geniculis tarsis- 
que nigris.
