orowdi'd, the anterior and lateral mari;ins pale fnlvons, tlie disc blackisli: scntellnm 

 broader than long; elytra more strongly pnnctnred than in the two preceding 

 species, the punctures here and there arranged in irregular rows, the lateral and 

 apical margin and a triangular narrow stripe, surrounding the scntellnm, fulvous > 

 the rest black; abdomen sjjotted with black, the sides of the breast and the legs 

 black ; claws biiid ; anterior coxa! cavities closed.

Timarchosoma gen. no v. 



Body snbglobnlar, terminal joint of palpi truncate, scarcely longer than the 

 preceding one, antennae short, the terminal joints slightly transverse, thorax short 

 and strongly transverse, four times broader than long, the sides not thickened, 

 strongly oblique; scntellnm small: elytra snbglobnlar, the posterior half abruptly 

 deflexed, the sides projecting beyond the abdomen below, tibiae prismatic, short, 

 the anterior ones curved, shai-ply edged at the sides and above, first joint of the 

 tarsi as long as the following two joints together, claws simple, closely approached; 

 prosternum narrowly elongate, mesasternum transverse, narrowed at the base, 

 metasternum three times longer than the mesosternum, the first abdominal segment 

 distinctly longer than the metasternum; anterior coxal cavities open. 



The insect for which the present genus is proposed is the most globular shaped 

 form of the entire grouji of the true Clinj^omclinae., resembling in that respect some 

 species of Timnrcha; half the underside is covered b}- the sides of the elytra 

 making the abdomen appear to sink within them; the thorax is also of exceptional 

 width and the compressed, dilated and prismatic shape of the tibiae add another 

 characteristic detail to this extraordinary genus, resembling somewhat species of 

 Entomoscelis ; the ojjcn coxal cavities show the affinity however to lie with the 

 genus Ckri/somela. 



Timarchosoma transvaalense sp. nov. 



Below black, above obscure metallic dark violaceous, antennae piceons, head 

 and thorax minutely punctured, elytra less closely and scarcely more strongly 

 punctured. 



Length 4 lines. 



Head opaque, extremely finely and closely punctured, the anterior margin 

 of the labrum fnlvons, antennae scarcely extending beyond the base of the thorax, 

 the basal joints more or less fulvous below, the terminal five joints widened, 

 with the exception of the last, not longer than broad ; thorax about four times 

 broader than long, the sides straight, strongly oblique and narrowed towards 

 the front, all the angles rather obtuse, the anterior margin deeply concave, the 

 posterior one parallel, the surface without impressions, the margins not thickened, 

 the disc punctured like the head; scntellnm small, triangular: clj'tra snbglobnlar, 

 the posterior half strongly and abruptly deflexed, the apex pointed, the surface 

 finely and less closely punctured tlian the thorax, the interstices finely acicnlatc, 

 the punctuation evenly dispersed over the entire surface ; underside and legs 

 blackish, very finely punctured, the apex of the tibiae and the tarsi below covered 

 with dense fulvous pubescence.
