204 RAWASIA RITSEMAE. 



Legs moderate; tibiae somewhat compressed and gra- 

 dually enlarged towards the apex ; tarsi with the first 

 joiut triangular ; the second of a distinctly transverse trian- 

 gular shape, bisinuated at the apex; the third of a struc- 

 ture which is unusual in the family, being entirely visible , 

 very large, rounded and bilobed ; the fourth joint elonga- 

 ted , its internal claws long and parallel with the outer tooth. 



A most remarkable genus , by the development of the 

 third joiut of the tarsi , quite unusual in the Anthribidae , 

 this joint being hidden in the greater majority of the spe- 

 cies. In the genus Lagopezus Schönli. it is free, but in 

 no way of so considerable dimensions as in the present 

 genus. In the genus Eucorynus vSchönh., close to which 

 the new genus will have to be placed, the third joint is 

 partially free but rather small.
