the five preceding joints, the sixth and seventh are compressed and 

 more or less sharply angular inwardly, the third is not longer than 

 the fourth ; prothorax a little ampliated and rounded laterally in the 

 middle, sinuate in the posterior part and with the basal angles either 

 sharp {dispar, rihatlensis) or moderately rounded (delagoensis), basal 

 part moderately sinuate ; scutellum cordate ; elytra sub-parallel, 

 somewhat depressed in the dorsal part, covering only the basal part 

 of the propygidium, pygidium sloping ; anterior tibiae tri-dentate 

 outwardly, and with a slender inner spur, no oblique carina on the 

 outer part of the intermediate and posterior ones, the latter are 

 dilated at the apex, the spurs are compressed, the upper one is either 

 broadly rounded (rihatlensis) or blunter than the lower, the tarsi are 

 long, slender, bristly at the apex of the joints, and also beneath in 

 the case of the posterior ones, the basal joint of which is not longer 

 than the one following, but plainly wider ; claws long, slender, some- 

 what widened at the base and having a post-median, short, vertical 

 tooth ; membranaceous hinge of the ultimate abdominal segment 

 very plain. 



Although I have not seen Klug's type of the genus, the excellent 

 figures given of C. dispar leaves no doubt as to the identity of 

 the insect. Brenske's genus Diaclaspus founded on a species, 

 D. delagoensis, is in all respects identical with Cyclomera. 



I know only the males of the three species I include in this genus, 

 but Klug has given the figure and description of what he believed to 

 be the female of Cyclomera dispar. Like the females of the two 

 species of Macrophylla known to me, it is more heavily built than 

 the male, more convex, the femora are very short and thickened} the 

 hind ones almost resembling a disk, the tibiae are short, the hind 

 ones even shorter than the femora, tolerably three-cornered, and 

 nearly as broad as long at the apex, with the spurs strong, short, 

 and bluntly pointed ; the tarsal joints are very short, and the claw 

 very small. 



The species included in this genus are densely but somewhat 

 briefly hairy on the prothorax and scutellum, and have a very long 

 pubescence on the pectus ; the elytra are shagreened and clad with 

 a very short, appressed pubescence. 



Key to the Species, 

 A 2 . Frontal part simple. 



B 2 . Head with a clypeal not grooved keel. 



C 2 . Clypeus rounded in front. 



Keel very high, seventh antennal joint compressed and 

 acuminate inwardly dispar.
