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

 and the posterior tarsi rufo -fuscous. 



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



Genus 10. PHYSIMEKUS*. (TAB. III. figs. 2-7.) 

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

 LABRUM transverse subrotundatum. 



PALPI MAXILLARES elongati, art. 2 nd0 subovato, 3 ampliori. 

 PALPI LABIALES elongati, subcylindrici. 

 AjrmnLB approximatce, robuslce,filiformes aut subincrassatce. 



CAPUT breve, antice subproductum, plerumque inter oculos tuber cula turn 

 aut foveolatum. 



THORAX quadratus aut elongatus, rarissime transversus ; angulis an- 

 terioribus acutis, haud ut in Ehinotmeto rotundatis. 



ELYTRA lata, subparallela, punctato-striata aut punctata. 



PEDES : femoribus anter. ad apicem dilatatis, tarsorum art. I mo trian- 

 gularly 2 ndo brevi, minuto ; femoribus posticis incrassatis, ovatis ; 

 tibiis brevibus, apicem versus dilatatis, plerumque simplicibus(haud 

 ad marginationem calcaratis) ; tarsis brevibus et attenuatis. 



Labrum transversely subrotundate. 



Maxillary palpi (Tab. III. fig. 3m, fig. 4m) 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. 3 n, fig. 4 n) elongate, subcylindrical ; 

 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, m&incrassated ; 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 ;
