mens of ruficornis, so conclude that they are only entitled to 

 varietal rank. I propose the name semirufus for this form.

Tychius armatus new species. 



Elongate-oval, convex, robust, black, moderately densely clothed with 

 narrow grayish scales not concealing the surface sculpture above, the scales 

 of elytra being longer and more slender, those of the striae very fine and 

 setiform; erect setae absent. Beak stout, one-fifth shorter than prothorax; 

 feebly arcuate, slightly tapering and flattened towards apex; densely 

 squamulose below antennal insertion, glabrous at tip; punctures con- 

 fluent longitudinally; apex smooth at middle. Antennae inserted at 

 apical two-fifths of beak; color dark, scape reddish, not attaining the 

 eyes; funicle seven-jointed, second joint two-fifths shorter than first, 

 longer than third, outer joints subequal, last two slightly transverse; club 

 elongate-oval, scarcely pointed, nearly as long as five preceding joints. 



Prothorax slightly wider than long; sides nearly straight and subparallel 

 from base to beyond middle, thence strongly converging to apex; apical 

 constriction indicated by a feeble sinuation; base twice as wide as apex; 

 disk with large, circular, moderately dense punctures. 



Elytra nearly one-half longer than wide, more than twice as long as 

 the pronotum and one-third wider at the humeri; sides parallel, broadly 

 rounded behind; tip of pygidium visible, the elytral apices being very 

 feebly separately rounded; disk striate, the intervals finely irregularly 

 punctured; vestiture nearly uniform in distribution, a little denser on the 

 sutural interval. 



Femora strongly clavate, deeply notched within at apex, the middle 

 and hind pairs distinctly toothed, the fore pair feebly so. Length 3.8 

 mm., width 2 mm. 



Six specimens from Graybeard Mountain, North Carolina, 

 June 19 to 25, in the cabinet of Mr. Wenzel, who has kindly 

 permitted me to retain a pair in my own collection. They 

 were collected by Mr. Wm. Beutenmuller. Armatus belongs 

 to Casey's Group I and is easily distinguished from the other 

 species assigned thereto by all the femora being toothed. It 

 should follow sordidus in a cabinet arrangement. The type 

 described above is a male. The rostrum of the female is as 

 long as the prothorax, more slender, nearly cylindrical, very 

 feebly tapering at apex, and the point of antennal insertion is 

 a little less apical. 



Tychius suturalis Schaeffer. 



Specimens collected in the Davis Mountains, Texas, July 9, 

 were identified as T. snturalis for Mr. Wenzel by Col. Casey.
