VII. AULOBARIS LeOonte, 1876. (Gr., "cylindrical" -f- Baris.) 



Strongly convex, shining species of elliptic- form, having the 

 beak cylindrical, rather slender, as long or longer than thorax ; 

 antennae slender, second joint of funicle nearly as long and stout 

 as the first, fully as long as the next two united, joints 3 7 

 gradually slightly wider; prosternum deeply, broadly silicate; 

 third elytral interval with a small oblong spot of pale scales at 

 base; third tarsal joint very wide, deeply bilobed.

558 (8901). AVLOBARIS SCOLOPAX Say, 1831, 26; ibid, I, 295. 



Oval-elliptic. Dark reddish or chestnut brown; head and under 

 surface darker, the latter with a small yellowish scale-like hair in each 

 puncture. Beak longer than head and thorax, finely and rather sparsely 

 punctate. Thorax one-third wider than long, distinctly, not strongly, 

 constricted near apex, finely and densely punctate, the punctures usually 

 separated by about one-half their own diameters. Elytra at humeri 

 one-fourth wider than thorax, thence distinctly converging to the 

 broadly rounded tips; strias deep, not punctured; intervals each with a 

 row of shallow, close-set transverse punctures, those of the second and 

 third intervals broadly confused. Length 3.3 3.7 mm. 



Frequent throughout southern Indiana, much less so in the 

 northern counties; July 13 Sept. 27; swept from thistle. Not- 

 taken near New York City. Ranges from northern Indiana and 

 Wisconsin south to District of Columbia, Georgia and Texas. 

 At Dallas, Texas, on July 3 the ''adults were found feeding on 

 the buds of Baldwin's iromvccd. }'n-noni<i Ixiltliriiti Torr. and 

 burrowing in the heads of r<ir<lin<x." (Pierce.} The thoracic 

 punctures vary considerably in density, and there is often a trace 

 of a median smooth line.
