Elongate, subcylindrical. Fuscous or smoky to piceous, rather densely 

 clothed with ash gray prostrate hairs ; tibia-, base of antennae and femora 

 paler. Thorax longer than wide, much narrower than elytra; coarsely, 

 densely and deeply punctured. Length 5.5-6.5 mm. 



Western and southern portions of the State; frequent. Not 

 taken north of Vermillion County. May 24-August 11. Occurs on 

 the foliage of wild grape. 



2116 ( 6725). Fidia viticida Walsh, Pract. Entom., II, 1867, 87. 

 Elongate, subcylindrical. Dull reddish- 

 brown, rather thickly clothed with short gray- 

 ish-yellow pubescence; antenna? and legs 

 paler. Thorax wider than long in female, 

 often longer than wide in male, widest at or 

 just behind the middle, finely and densely 

 punctate. Length 6-7 mm. (Fig. 492.) 



Southern two-thirds of the State, ^ 

 common; probably throughout. May 

 2 7- July 21. Occurs on the wild grape 

 and occasionally does much damage to 

 the cultivated varieties. The adult bee- 

 tles may be killed by the use of an arsen- 

 ical spray with lime, at a strength of Kg. 492. 

 one pound to 150 gallons of water. The 

 larvae about the roots may be destroyed by bisulphide of carbon or 

 by wetting the soil before the end of June with a kerosene emulsion 

 diluted nine times with water, a gallon or two being poured about 

 the base of the vine.
