Type locality. — Barnesville, Ga., August 11, 1927 (T. L. Bissell). 



Type.— Male, Cat. No. 29034, U.S.N.M. Type and paratype. 



Resembles scrohicoUis Bolieman and is closely related to that 

 species. It is shorter, has a distinctly arcuate and backward bent 

 rostrum and the strial punctures at the base are larger, more closely 

 set and quadrate. The two specimens differ in a few respects, the 

 smaller one having smaller strial punctures with the pronotum 

 narrowed just before the base. 



LIXUS TKICRISTATUS, new species 



Elongate cylindrical, nearly four times as long as wide. Black, 

 feebly shining, dorsum with dull plumbeous effect; vestiture fine, 

 forming a wide gray lateral vitta on elytra and prothorax; elytral 

 vitta pale whitish gray; antennae dark reddish brown, legs black. 

 Head moderately coarsely and deeply punctate; fovea rounded and 

 deep. Rostrum in the female a little shorter than the prothorax, 

 thick, distinctly arcuate, somewhat coarsely, deeply and densely 

 punctate at base, finely in apical third, finely subcarinate in basal 

 half. Scrobes not extending to apical third. First funicular joint 

 very wide, about one-fourth longer than wide ; second slightly longer 

 but more slender, scarcely wider than third and fourth, which 

 combined equal it in length. Prothorax short, distinctly wider 

 than long, subconical; basal half subparallel; punctures moderate 

 sized and fairly densely placed, interspaces very finely, irregularly 

 punctulate, a very short rather deep impression at middle just be- 

 fore the scutellum; vestiture fine, long, depressed, extending irreg- 

 ularly backward toward the base, a short median line at apex 

 extending one-third toward the base, each side of which there is 

 an incurved line directed toward the sides; at the sides a wide 

 vitta of yellowish gray thicker hairs. Elytra about four-ninths 

 as wide as long, wider than prothorax at base; humeri not promi- 

 nent, umbone hardly visible; sides subparallel in basal two-thirds, 

 apices scarcely separate; punctures rather small and deep in rows, 

 vestiture very short and fine, lightly mottled, a vitta of longer, 

 lighter gray squamules covering the outer four intervals. Ventral 

 surface with longer hairs, dense, partly concealing the fine surface 

 punctulation. Inner margin of anterior tibiae distinctly serrulate. 



Rostrum in the female longer than in the male. First ventral 

 segment in the female feebly convex; third, fourth, and fifth seg- 

 ments strongly separated. 



Rostrum in the male notably shorter and thicker. First ventral 

 segment broadl}'^ but feebly impressed at middle. 



Length, 7.2-10.4 mm. ; width, 2-2.8 mm.
