RHYNCHOPHORA. 
All the twenty odd species of Meanthribus known to me have three prominent 
tufts on the pronotum. ‘The insect named Anthribus lividus by Leconte and Horn is 
described as being without tufts. As the beak, moreover, is said to be entirely flat, 
not at all carinate, I conclude that the N.-American species does not properly belong to 
Neanthribus.

1. Neanthribus championi, sp. n. (Tab. XII. figg. 18, 18a.) 
3 2. Blackish-brown, pubescent clayish-grey, variegated with brown and greyish-white. Antenna rufous, 
club brown, end-segment paler than 9 and 10. Legs long-hairy, rufescent, spotted with brown. Head 
and rostrum luteous, the former with indistinct white patches. Pronotum with a high mesial tuft which 
is black on the hinder side, this colour being continuous with a large black patch which extends to base 
and is variegated with some milky-white pubescence; rest of pronotum luteous, unicolorous in middle, 
variegated with brown laterally ; a small tuft on each side of the large one, with two or one small, sharply 
marked, elongate, black spots in front; at apical margin two luteous tufts feebly tipped with white. 
Elytra tessellated with black along suture, the spots more or less oblique, a larger elongate spot before apex, 
a small black dot near tuberculiform sutural angle, alternate interspaces feebly pustulated and faintly 
tessellated, third interspace with sub-basal tuft and a smaller one before middle, obliquely behind the 
latter a still smaller pustule each in interspaces 5 and 7, the area behind these three tufts being grey; a 
larger tuft in third interspace before apical declivity and another of the same size further back in the 
fifth ; side of elytron without long hairs. 
Length 33-64 millim.
