width of the interstice. The clothing is denser than on other- 

 species of Mdanterius. The punctures of the under-surface 

 are practically the same on all three species. 



On the present species the sutural interstice is strongly- 

 elevated from the middle to the apex, the third is similarly 

 elevated from before the middle to the apex, the fifth is 

 elevated for a less distance, and the elevated part suddenly 

 terminates some distance from the apex ; the seventh is also 

 elevated for part of its length. On the basal third the inter- 

 stices are all much alike. The tooth on each of the front 

 femora is so minute that it is quite invisible from most direc- 

 tions ; on the others it is also small, but being equilaterally 

 triangular is moderately distinct. The mesosternal receptacle 

 is so strongly concave as to leave the middle coxae exposed, 

 but the front margins curve round the coxae, and from the- 

 sides appear as short processes behind them. 



On nemorhinns the interstices are only moderately 

 elevated, and the elevated parts are confined to the posterior 

 declivity, instead of commencing some distance before sam.e. 

 The tooth on each hind femur is very strong and acute, on 

 the others it is quite distinct, although smaller. The meso- 

 sternal receptacle is much shallower and much smaller than in 

 lamellatus, and curves less around the middle coxae. Its 

 rostrum is longer and straighter than in lameJlatus and len- 



On leucojohceiis the elevated parts of the interstices com- 

 mence much as on latiiellatvs, but are somewhat less strongly 

 elevated, although more so than on nemorhinus, and the- 

 sutural interstice, although elevated above the second, is not 

 as strong posteriorly as is the third, whereas on lawellafu!^ it 

 is quite as strong. The tooth on each front femur is small 

 but distinct, on the middle pair it is acute and fairly large, 

 on the hind pair large and acute (larger than on nentorhiriits). 

 The mesosternal receptacle is intermediate between that of 

 lameUofus and neinorhinvs. 



Melanterius nemoehinus, n. sp. 



Colour and clothing much as in preceding species. 



Rostriun long, thin, and almost straight, with clearly- 

 defined punctures, becoming linear in arrangement towards, 

 and concealed about, base. Scape as long as funicle, inserted 

 two-fifths from apex of rostrum ; first joint of funicle dis- 

 tinctly longer than second. Prothorax without trace of a 

 median carina. Elytra not much wider than prothorax, but 

 sides and punctures much as in preceding- species. Leno-th,.
