Mr. Jacoby has described all the tibiae as armed with a short spine ; 

 M. Duvivier gives the anterior pair as unarmed. I have failed to 

 discern any tooth on the anterior pair. , 



Genus NADRANA. 



Dr. Chapuis has given an erroneous diagnosis of this genus ; he 

 states that the anterior acetabula are open, the apices of the anterior 

 tibiae unarmed, and that the basal joint of the metatarsus is only equal 

 in length to the following two united. In all my specimens, including 

 the type, the anterior acetabula are entirely closed, the anterior tibiae 

 are armed with a distinct spice, and the basal joint of the metatarsus 

 is longer than the following three united. 



Beyond the shallow excavation on the disc of the thorax in 

 Nadrana, which I look upon as a specific, not generic, character, and 

 a slight difference in the relative lengths of the second and third 

 joints of the antennae, I do not see any reason for separating Candezea 

 (Chap., Ann. Mus. Civ. Gen., xv, p. 24) from the present genus. 



Genus OCHRALEA. 

 Dr. Chapuis, in the Genera des Coleopteres, gives the anterior 

 acetabula in Ocliralea as closed ; I have examined many specimens of 

 OcliraJea flava (Chapuis' type) as well as of other allied species of the 

 genus, and have found in every instance the acetabula open ; Mr. 

 Jacoby, whom I requested to examine the specimens in his collection, 

 has found them in one solitary instance closed, but in all the rest 

 open. It thus appears that open acetabula are the rule, and closed 

 ones the exception in the present genus, and that Ochralea must be 

 removed from the section in which it at present stands, and be placed 

 near Luperodes, with which genus it becomes a question as to whether 

 or not it ought to be amalgamated. As our knowledge of the 

 GaJerucina extends, it will, I think, be found that the open or closed 

 states of the anterior acetabula have not the same primary importance 

 in the arrangement of the family as that assigned to them by Dr. 

 Chapuis ; as seen above, the acetabula in individuals of the same species 

 vary from open to closed, whilst in some genera, Si/oplia, Metroidea, and 

 others, the anterior acetabulum is often closed on one side, and open
