X. bizonata, sp. nov. Sat late ovalis; sat nitida; sat fortiter 
convexa; obscure cyanea, antennarum parte intermedia 
elytrorum parte dimidia anteriori mesosterno metasternoque 
rufo-fulvis ; capite fere ut preecedentis sed antennis paullo 
brevioribus, articulo 3° (?femine solum) quam 4"° manifeste 
longiori; prothorace fere ut precedentis sed sparsim sat 
fortiter punctulato; elytris (colore excepto) fere ut prece- 
dentis sed paullo magis elongatis; pedibus fere ut prece- 
dentis sed tibiarum posticarum sulci margine externo minus 
distincte crenulato. Long., 1} 1.; lat., <1. 
An easily recognisable species on account of its color and 
markings.

ARSIPODA. 
There is great diversity of facies among the species that, 
according to Dr. Baly, ought to be attributed to this genus ; but 
amid this diversity there seems to be great structural uniformity. 
T refer below (under A. eneofulva) to the sexual characters. The 
males, it may also be noted, have (I think in all the species) a 
fovea near the apex of the fifth ventral segment from which a 
furrow (varying from a deep sulcus to a fine line) runs hindward 
towards the base of the seyment. In some few species the males 
have the hind femora strongly toothed. The following tabulated 
statement of characters includes those of the previously named 
species with the exception of A. bifrons, Er., which I am unable 
to place. I should have felt some hesitation in identifying 
A. chrysis, Oliv., had I not possessed an example ticketed as that 
species from the collection of Dr. Chapuis who probably had good 
reason for his identification. 
A. Elytra dark or metallic. 
B. Seriate puncturation of elytra well defined-— 
at any rate near the base. 
C. Prothorax with a transverse impression. 
D. Elytra dark, prothorax (at any rate 
partly) red. . 
E. Anterior femora testaceous or red.
