 grave River (Henry Hacker). 



The punctures (except on sides of elytra), fovese, and 

 granules are entirely concealed by the clothing. On abrasion 

 the derm of the prothorax is seen to be opaque, whilst that of 

 the elytra is shining; the punctures of the latter, though 

 smaller posteriorly than elsewhere, are still of considerable 

 size there, fully as large as those of the prothorax. 



Paletonidistus, n. g. 



Head moderately large; forehead trisinuate; ocular 

 fovea deep. Eyes moderately large, subovate, rather finely 

 faceted. Rostrum moderately long and rather thin, curved, 

 with a shallow groove on each side above the scrobe. Scape 

 not the length of funicle, inserted nearer apex than base of 

 rostrum ; two basal joints of funicle elongate ; club briefly 

 ovate. Prothorax moderately convex, walls almost vertical, 

 base bisinuate, sides and apex moderately rounded. Scutellum 

 absent. Elytra subovate, much wider than prothorax. Pectoral 

 canal deep and rather narrow, terminated between four anterior 

 coxae. Mesosternal receptacle raised, longer than wide, ridged 

 along middle, emargination semicircular; cavernous. M eta- 

 sternum very short; episterna narrow but traceable through- 

 out. Abdomen rather large; two basal segments large, suture 

 between them rather feeble but traceable throughout; first as 

 long as second and third combined, intercoxal process wide, 

 third and fourth combined the length of fifth and slightly 

 shorter than second. Legs rather long; posterior coxae not 

 touching elytra; femora subclavate, acutely dentate, not 

 grooved, posterior not extending to apex of body; tibiae thin 

 and compressed, bisinuate beneath, tarsi long, thin, and 

 polished above, third joint not much wider than second but 

 deeply bilobed, claws thin. Elliptic-ovate, convex, squamose, 

 tuberculate, apterous. 



Allied to Paleticus and Onidistus, from both of which it 

 may be distinguished by the shape of the mesosternal receptacle. 



Paletonidistus teisinuatus, n. sp. 



Black, opaque; antennae and tarsi red and shining. 

 Densely clothed with muddy scales, interspersed with longer 

 and stouter but almost unicolourous scales, becoming sub- 

 fasciculate on tubercles ; under-surface sparsely clothed. Head 

 and basal half of rostrum with large and moderately-dense 

 scales. 



Head moderately convex, basal portion visibly punctate ; 

 forehead distinctly but not deeply trisinuate; ocular fovea
