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<ind 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. lunatu s, niger, thorace subovali, latitudine vix breviore, marginibus 

 punctatis, elytris subtilius punctatis punctisque maioribus 3-seriafim 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 tibiae are 

 curved. The rhinarium is red and trapezoidal in two specimens ; in another it 

 is scarcely to be seen. 



10. N. o rb i c oil is, niger thorace rotundato, marginibus punctatis, elytris 

 distinctius punctatis, parcius pilosis, utrinque fascia dentata maculaque postica

 domine nigro ciliato, ano griseo-pubescente. Long. '73 '90.

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 tibiae 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 tibiae ; 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.

N. tomentosus Weber, Observ. 47, (1801.) 



Common throughout the Atlantic States awd 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 

 sexes ; the former 1 have observed only in males. The club of the antennae 

 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.
