apex, black. Legs flavo-fuscous, the anterior femora being riavous 

 and the posterior tarsi rufo-fuscous. 



South Carolina, Uiritecl States. In the collection of Mr. Waterhouse. 



Genus 10. PHYSIMERUS*. (Tab. III. figs. 2-7.) 

 Dej. Cat. ed. 3, 1837, p. 407. 



Labrtjm transverse subrotundatum. 



Palpi maxillares elongati, art. 2" do subovato, 3 ampliori. 



Palpi labiales elongati, subcylindriei. 



Antenna; approximator, robwstce, filiformes aid subincrassatte. 



Caput breve, antice subproductum, plerumque inter oculos tuberculatum 

 aut foveolatum. 



Thorax quadratics aut elongatus, rarissime transversus ; cmgulis an- 

 terioribus acutis, haud ut in llhinotmeto rotundatis. 



Elytra lata, subparallela, punctato-striata aut punctata. 



Pedes : femoribus anter. ad apicem dilatatis, tarsorum art. l mo triau- 

 gidari, 2, ndo brevi, minuto ; femoribus posticis inerassatis, oca t is ; 

 tibiis brevibus, apicem versus dilatatis, plerumque simplicibusChaud 

 ad marginationem calcaratis) ; tarsis brevibus et attenuatis. 



Labrum transversely subrotundate. 



Maxillary palpi (Tab. III. fig. 3 m, fig. 4 hi) elongate, more or less 

 subincrassated ; the basal joint is minute ; the second subovate, the 

 apex being truncate ; the third joint is larger than the second, and 

 also ovate ; the terminal joint is smaller than the others, and conical. 

 The different species of this group seem, while exhibiting a manifest 

 relationship in the general form of the maxillary palpi, to be subject 

 to more variation inter se respecting them, than is found in the other 

 genera : possibly they may be hereafter subdivisible into different 

 sections. 



Labial palpi (Tab. III. fig. 3w, fig. 4n) elongate, subeylindrical ; 

 the basal joint is, in outline, parallel ; the antepenultimate slightly 

 dilated towards the apex, and the terminal joint elongate and atte- 

 nuated. 



Antenna? tolerably approximate, situated under and between the 

 inner margins of the eyes ; robust ; generally filiform, or, in a very- 

 few species, subincrassated ; the first joint is elongate, dilated and 

 incurved outwards towards the apex ; the second short, narrower 

 than the first, ovate ; the third as long as (and in the males some- 

 what longer than) the first, attenuated, subincrassated at the apex ;
