reduce them to mere shreds. The preparatory stages of this 

 beetle are not yet known."* 



In 1870, Mr. Riley received the beetle from Bunker Hill, 

 Illinois, where it was feeding on the leaves of grapes. f 



In his "Materials for the Study of the Phytophaga of the 

 United States," Mr. G. R. Crotch describes the species murina, 

 from the Middle and Southern States, but seems to have over- 

 looked viticida, and did not mention it.+ In his paper on 

 " The Eumolpini of Boreal America," Dr. G. H. Horn unites 

 murina with viticida, and gives the distribution as being from 

 the " Middle States to Dakota, Florida and Texas. "|| He also 

 unites with the species F. lurida Leferre, " Catalogus Eumol- 

 pidarum," Mem. Liege, 1885, p. 76 (separate). 



Prof. H. F. Wickham records viticida from the vicinity of 

 Iowa City, Iowa,§ and Prof. Riley has recorded both murina 

 and longipes as injuring the foliage of grapes at Vineland, 

 Arkansas'* 



This is a summary of all the available information relating 

 to the species up to December, 1893, tne time when I began my 

 studies of larvae sent me from the vicinity of Cleveland, 

 Ohio, where they were said to occur in great numbers about 

 the roots of grapes, causing very serious injury by eating the 

 outer bark. 



DESCRIPTION OF THE SEVERAL STAGES. 



Of the following descriptions, that of the adult is copied 

 from Walsh; those of the preparatory stages are my own, 

 drawn from material taken from the vineyards about Euclid 

 and Nottingham, Ohio. 



Adult: A, Fig. 1, PI. IX. Chestnut rufous, punctured, 

 and densely covered with short, grayish-white prostrate hairs, 

 so as to appear hoary. Head rather elosoly punctured, with
