326 Mr. M. Jacoby's contributions to the knowledge of 
closely and strongly punctured, with an obsolete depression at 
each side near the base; elytra closely and strongly punctate striate, 
the interstices finely rugose and punctured ; legs very robust, 
piceous ; the base of the tibiae and the tarsi obscurely fulvous, inter- 
mediate tibiae dilated at the apex into a tooth, posterior ones with 
a distinct tooth at the middle. 
Eah. Natal. 
This Chsetocnema, of which a single apparently male 
specimen is before me, possesses the longest antennae of 
any species of the genus known to me. The structure 
of the head is also peculiar. In the other sex the 
antennae are probably shorter. 
Amj)himela ornata, sp. n. 
Ovately-rounded, black, head, and the basal joints of the 
antennae fulvous ; thorax transverse, piceous, impunctate ; elytra 
very minutely punctured, flavous, the suture and three dentate 
transverse bands black, base of the tibiae flavous. Length, If lines. 
Head fulvous, scarcely perceptibly punctured, without any 
frontal tubercles and carina, the sides near the eyes with a short 
oblique groove ; the antennae widely separated at the base, not 
extending to the middle of the elytra, the lower three and the 
apical joint fulvous, the others black, second joint thick, scarcely 
shorter than the third one ; thorax three times broader than long, 
the sides nearly straight, the anterior angles strongly oblique, the 
posterior ones preceded by an oblique groove which extends 
upwards some distance near the lateral margins, the posterior 
margin broadly rounded, the surface extremely minutely punctured, 
piceous ; scutellum broad, black, its apex rounded ; elytra scarcely 
more strongly punctured than the thorax, flavous, the suture, a 
transverse band below the base, curving upwards at the shoulders 
and joined at its middle to another band, slightly wider and placed 
at the middle, as well as a third band near the apex enclosing a 
flavous spot, black ; underside and legs black, the extreme base of 
the femora fulvous, the base of the tibiae and the tarsi more or less 
flavous, posterior tibife mucronate, anterior ones unarmed, the 
former widened at the apex, the first joint of the posterior tarsi as 
long as the following two joints together ; claws appendiculate, 
anterior coxal cavities closed.
