In my table of the genus would be placed in A, from all 

 i)he species of which it may be distinguished by the hind 

 tibiae of the male. The structure of these represents still 

 -another remarkable aberration in this highly interesting genus. 

 Each is somewhat thickened and flattened on the basal half 

 (but not at the extreme base) with the thickened portion 

 shining, and marked by a number of fine transverse carinae ; 

 then on the apical half, on a narrower space, but not on the 

 same plane, there are other short ridges, dividing the side, as 

 it were, into small cells. The front tibiae are also remarkable. 

 The general outline and the intercoxal process of mesosternum 

 are somewhat similar to those of the male of niger, but the 

 sculpture is different. 



The prothorax of the male could scarcely be called granu- 

 late, but there are numerous shallow impressions that mark 

 some of the boundaries of somewhat granuliform spaces. In 

 the female, however, the granules are more conspicuous, and 

 there are some very distinct punctures. 



Mandalotus interocularis, n. sp. 



o* • Black, antennae and tarsi reddish, tibiae, coxae, and 

 under-surface partly or entirely diluted with red. Densely 

 clothed with greyish, more or less variegated scales ; and in 

 addition with stout more or less erect setae, varying from white 

 tto black. Under-surface with rather dense but fine setae or 

 pubescence. Tibiae with long clothing, especially on the under 

 surface. 



Head with a narrow inter-ocular fovea. Rostrum con- 

 vex and feebly carinated along middle ; scape long and thin, 

 rather lightly dilated at apex; first joint of funicle distinctly 

 longer than second, second almost as long as third and fourth 

 combined. Prothorax moderately transverse, sides strongly 

 rounded ; with close evenly-rounded granules, of rather large 

 size, and readily traceable through clothing; with a narrow 

 median line, continuous to base and almost to apex. Elytra 

 at widest no wider than prothorax across middle, shoulders 

 evenly rounded, sides strongly incurved near apex; with 

 regular rows of fairly large punctures ; alternate interstices 

 moderately elevated. Under-surface with dense fine punc- 

 tures, with a few of larger size scattered about. Metasternum 

 depressed in middle. Abdomen with basal segment depressed 

 between coxae, the depression bounded posteriorly by a narrow 

 curved impression, immediately outside of which is a very 

 narrow carina, that is fairly close to the apex, which is 

 strongly incurved to middle. Legs rather long; front coxae 

 widely separated ; front tibiae strongly bisinuate, the apex 

 acutely produced. Length (excluding rostrum), 5J-6J mm.
