from Phceaocerus by tlie former having " Prosieinal sulcus mar- 

 gined within by an elevated line only in its hinder part'' as 

 against " a continuous elevated line," it is to be noted that 

 Bonvouloir says of PJuenoc-erus ^^Sillon-viargiiial . . . etunt borde 

 en arriere inter ieurenwnt par une ligne eleve'e.^^ Quite possibly 

 the following species should have been referred to Phca^iocerus, 

 but it is evidently distinct from P. siibclavatus by its larger size, 

 and different antennte and hind cox?e. 



Dystrigonisthis ferrugineus, n.bp. 



Dark rusty-castaneous, appendages somewhat paler. Densely 

 clothed with short, rusty-red pubescence. 



Head with crowded punctures of moderate size; with a short 

 and rather wide median line; clypeus shallowly concave. An- 

 tenna3 rather stout, second joint short, third cylindrical, almost 

 as long as the three following combined, fourth-eighth short, 

 subequal and distinctly transverse, ninth and tenth somewhat 

 longer and wider (and with small fovese at apex), eleventh about 

 as long as the three preceding combined. Prothorax with sides 

 rather strongly rounded in front, and then obliquely increasing 

 in width to near base, which is somewhat wider than elytra, and 

 almost twice the width of apex; with dense punctures of moder- 

 ate size, smaller in middle than elsewhere, and becoming crowded 

 on sides. Elytra feebly decreasing in width from base; densely 

 granulate-punctate about base, punctures becoming smaller and 

 sparser posteriorly; striation as in preceding species. Hind coxie 

 with greatest length about equal to that of second abdominal 

 segment, curvilinearly decreasing to sides, which are very short; 

 basal joint of hind tarsi somewhat shorter than the rest com- 

 bined; second, third, and fourth regularly decreasing in length 

 and width, fourth not bilobed and scarcely produced on under 

 surface. Length, 11-12^ mm.

The antennie so regularly increase in width, that the three 

 apical joints can scarcely be regarded as forming a club; from 

 above, the second joint appears to be slightly shorter than the 

 fourth; but, from below, it is seen to be slightly longer. The
