DESCR. CORPUS nigro-brunneum, oblongo-obovatum, pilis flavescenti-griseis vestitum, 
subtilitér vagéque rugulosum. 
CAPUT nigrum, collo haud constrictum. Labrum Palpique structura ut in, prece- 
dentibus, ferruginea. Antenne fusco-ferrugineze basi apiceque dilutiores, sub- 
incurve, thorace dimidio breviores, apice valdé incrassate ; articulis duobus 
baseos sequenti pauló crassioribus et longioribus, ovali-cylindricis ; tertio sub- 
 obeonico; 4—7 precedenti brevioribus, obconicis, sensim crassioribus ; 8—10 
transversis, zequalibus, precedentibus dupló erassioribus ; extimo contiguis pauld 
longiori et angustiori obtuso. 
Truncus. Thorax brunneo-niger, convexus, trapeziformis, anticé subcompressus, 
posticé dilatatus et fer& dupló latior, longitudine feré latitudinis, lateribus ab 
apice ad basin rotundatis, margine postico truncato recto, sine excisione ullä. 
- Scutellum triangulare, nigrum. Coleoptra castaneo-brunnea, thorace dupló lon- 
-  giora et paulò angustiora a basi sensim ad apicem angustata, apice rotundata, 
_. Striis (suturali marginalique exceptis) nullis. Pedes piceo-brunnei ; 3 antici coxis 
globoso-pyramidalibus, femoribus latioribus et paulo brevioribus ; femoribus sub- 
dimidiato-ovatis, apice lateri interiori in mare constriéto ; tarsis in mare articulis 
tribus primis dilatatis ; postici femoribus in mare subtus in medio dente parvo 
acuto triangulari armatis. 
Itis obvious, from the description of this species, that it recedes 
materially not only from the characters of the foregoing, but 
even of the genus; its antenne being sub-incurved, the two 
first joints manifestly thicker than the three next, the eighth not - 
in the slightest degree less than the other joints of the club, and 
the last obtuse at the apex. "These differences, certainly, are so 
considerable, as in the system to warrant Latreille's institution of 
a new genus to include this insect and its congeners. In a mo- 
nograph like the present, I have not thought it necessary to follow: 
his example, because | know but this single species furnished with
