Nirina Weise. 

 Weise lias established ihis genus on a single species 

 N. Jacohyi (Deutsche Ent. Zeitschr. 1892 p. 403). I thiiik that 

 Gatenica ephippiata Dalin. (Mesodonfa transversofasciata Jac.) 

 which Stands in Gemminger's Catal. as a species of Diacantha, 

 should be placed in Weise's genus as well as Mesodonfa 

 imitans Jac. 1 cannot find sufficient diÜerences to justiiy its 

 Separation, although the shape of tlie thorax does not agree quite 

 with Weisels type, but every otlier characler, ineluding the 

 pubef-cent elytra is present. 



Hystaspes gen. n. 



Allied to Forphytoma and likewise of nietallic coloration, 

 the basal joints of the antennae filiform, the terminal ones tliickened 

 and shortened; thorax one half broader than huig, the sides 

 straight, the angles tubereuliform ; elytra much wider at the base 

 than the thorax, rugosely punctured and finely pubescent, their 

 epipleurae very narrow from the niiddle downwards, tibiae long 

 und siender, finely channelled, the metatarsus of the posterior 

 legs very elongate, claws bifid, anterior cavities open. 



This genus difi'ers from Pachytonm and all the other allied 

 genera by the siender tibiae and the elongate legs; the thorax 

 resenibles niore nearl}' that of Forphytoma but has all the angles 

 tuberculiform and is much less transverse in shape. 



A Single species is known to nie.
