California, at San Francisco and San Diego; only two males secured. The 
impressions of the thorax are very deep, the transverse undulated line is not 
interrupted at the middle; the rhinarium is red and trapezoidal; the anterior 
tarsi are strongly dilated.

New York and Lake Superior. I have only males of this species; of three 
from Lake Superior, the smallest has the rhinarium large, trapezoidal and 
black ; in the other two no rhinarium is visible. ‘The impressions of the thorax 
are very deep, the longitudinal line is more distinct than usual; the red band of 
the elytra, although reaching the lower margin of the epipleura, is not dilated 
there. 
The specimen from New York differs from the other three in having the 
elytra more finely punctured, and the red bands much more bright colored; the 
rhinarium is large and trapezoidal, as in the first mentioned specimen. 
I formerly considered the large specimens as N. hebes Kirby, (1. c. 96,) 
which by description seems closely allied, but is placed in a different division 
of the genus, with the *prothorax dilated anteriorly.”’ 
9. N. lunatus, niger, thorace subovali, latitudine vix breviore, marginibus 
punctatis, elytris subtilius punctatis punctisque maioribus 3-seriatim impressis, 
epipleuris, fascia utrinque angusta dentata, maculaque lunata postica rubris; 
antennarum clava ferruginea basi nigra, pectore flavo-piloso, abdomine nigro- 
ciliato, ano flavo-pubescente. - Long. :'75—:79. 
New York and Georgia. This species is named in Dejean’s Catalogue, but I 
cannot find that any description has yet been published. The posterior tibiw are 
curved. The rhinarium is red and trapezoidal in two specimens; in another it 
is scarcely to be seen. 
10. N.orbicollis, niger thorace rotundato, marginibus punctatis, elytris 
distinctius punctatis, parcius pilosis, utrinque fascia dentata maculaque postica 
lunata rubris, antennarum clava ferruginea basi nigra, pectore flavo-villoso, ab- 
domine nigro ciliato, ano griseo-pubescente. Long. -73—-90. n

Middle and Southern States, abundant. The rhinarium is short, triangular and 
reddish; the punctures of the elytra are furnished with tolerably long erect 
yellowish hairs; the tibie are nearly straight; the posterior ones of the male 
are gradually broadly dilated towards the tip. 
One male from the Sault de Sainte Marie, Michigan, differs in having glabrous 
elytra, and much more dilated posterior tibia ; the rhinarium in it is piceous, 
broad and trapezoidal. The hairs of the elytra may have been removed by 
accident, and the other characters seem scarcely sufficient for the definition of a 
new species. 
b. Thorace villoso. 
12. N. velutinus, niger, thorace, pectore, epipleurisque basi flavo-villosis, 
illo ovali subtransverso, lateribus sinuatis, elytris distinctius punctatis, fasciis 
utrinque duabus, dentatis rubris, epipleuris flavis. Long. :53—-85.

Common throughout the Atlantic States asd Missouri Territory. The anterior 
tarsi of the males are strongly dilated; the rhinarinm is red, sometimes large 
and trapezoidal, sometimes small and triangular; the latter form occurs in both 
ace the former I have observed only in males. The club of the antenne 
is black. 
As the two names applied to this species appear to be equal in date, I have 
followed other authors in adopting that of Fabricius, as his work is of a more 
systematic nature, and much more easily accessible.
