denser. Genitalia differ in being shorter, aedeagus wider (but not as 

 wide as verherans), apical blade broader, and bearing four bristles. 



Elytron: 6.6 ±0.6 mm (5.9-8.4). 32 spec. 



Female. — 'Not positively identified (see discussion below). 



Type.— Holotype of emissus: Male, labelled with orange circle 

 "Ga." (MCZ). Damaged specimen only one in type series.

 Dakota and Kansas.

In the material studied there are two different females associated 

 with the males on the basis of similarity in appearance and locality. 

 One seems to be the same as the female of verherans and the other a 

 distinct form (fig. ^k). The latter, from Ash, N.C., is tentatively 

 assigned to emissus but not with certainty. This also poses the 

 question as to the proper association of sexes in verherans, but that 

 cannot be answered at this time. 



11. Melanotus land Quate, new species 



Figures 5a, 9h; Plate 1/ 



Male. — Same as communis, but smaller in size, generally darker 

 in color; antenna as in communis, ratio of segments 2:3:4=5:9:12, 

 segment 4 about VA times as long as wide; pronotum narrower, ratio 

 of width/length =1.0-1.1, vestiture thicker, pronotal punctures 

 smaller and denser; genitalia shorter, aedeagus evenly tapering from 

 base to apex. 



Elytron: Holotype 6.6 mm; paratypes 6.7 ±0.6 mm (5.9-8.2). 

 17 spec. 



Female.- — Same as male, but larger. Genitalia as communis with 

 diverticulum branching from spermathecal duct, differs from communis 

 in that bursa has fewer spines, from 15 to 20 (allotype with 17). 



Elytron: Allotype 8.0 mm; paratypes 7.6 ±0.5 mm (6.7-8.7). 21 

 spec.
