OPHRYOTA. 
O. rapax, sp. nov. (8). Ovato-campliata; picea, squamis cinereis umbrinisque 
diverse int*eruiixtis vestita ; capite inter oculos concavo utrinque super oculos crista 
erecta (hac in rostrum baud continuata) insigni ; rostro quam caput multo longiori, 
in medio longitudinaliter leviter concavo, utrinque mox intra marginem lateralem 
leviter carinato; prothorace sat transverse, antice angustato, pone marginem 
anticum fovea sat magna leviter impresso, confuse sat grosse nec crebre ruguloso; 
elytris quam prothorax multo latioribus (maris quam feminae magis angustis magis 
parallelis), punctulato striatis, interstitiis convexis, 3° 5° que in parte posteriori 
tuberculis 2 vel 3 ornatis, humeids extrorsum tuberculiformibus ; tibiis ad apicem 
externum processu spiniformi (hoc ad apicem minute bilido) armatis. Long, (rostr. 
inch) 31 —4 1. Lat. 1|—2 1. 
Very like O. squamihunda, Pasc., but at once distinguishable by the peculiar 
spine-like external process at the apex of the tibiae, also by its evidently longer 
rostrum, frontal crests ending abruptly in front instead of gradually merging into 
the rostrum, evidently shorter prothoi’ax, etc. The less T .say about the arrange¬ 
ment of the squamosity the better, as all the examples before me seem more or less 
abraded. Judging, however, by the least abraded, I should expect that the pattern 
on a fresh specimen bears much resemblance to that of O. squaviibioida. 
Crown Point. 
DYSOSTINES. 
A single example (female) of this genus was taken at Crown Point. The 
specific characters of the previously-described species depend so much on the sexual 
differences of the males that it seems to me scai'cely justifiable to describe a 
Dysostines of which the male is unknown. 
OXYOPS. 
O. sicca, sp. nov. (2). Modice angusta; squamis albidis vestita, squamis hie 
illic interruptis sic ut notationes sat determinatai nonnullte formantur; antennis 
tibiis tarsisque obscure testaceis vel piceo-testaceis ; oculis prominulis ; rostro sat 
elongato ; prothorace trans basin quam longiori paullo latiori, a basi antrorsum 
arcuatim angustato, subtilius sat crebre ruguloso, subobsolete tricarinato; scutello 
modico; elytris insequaliter punctulato-striatis, interstitiis leviter convexis inter se 
sequalibus, humeris vix prominulis, striis suturalibus in parte mediana grosse 
foveatis; mesosterno antrorsum sat prominulo. Long, (rostr. inch) 4—5^ 1.
