There are at present 6 species of the genus Fidia known to Boreal America and by including those occurring in Central America there are 14 known species. Of these, Fidia viti- cida Walsh and Fidia lon- gipes Melsh. have been re- corded as being injurious to the native varieties of the domesticated grape. Fidia longipes (fig. 3) is found gen- erally throughout the Mis- sissippi Valley and in the Eastern States. It is, how- ever, less common than F. viticida. In Missouri and Kentucky it occurred in in- jurious numbers on the Con- cord and on Norton's Vir- ginia varieties of grapes. The earlier stages of this beetle are not yet known. For characteristic distinction of the species of Fidia reference is made to the works of Lefevre, Jacoby, Horn, and S-chseffer, as listed in the appended bibliography (p. 93). BEETLES FREQUENTLY MIS- TAKEN FOR THE GRAPE ROOT-WORM BEETLE. There are several different kinds of beetles injurious to the grapevine, and these when found in numbers are frequently mis- taken for the grape root-worm beetles. It is essential that an insect pest should be properly determined before any success- ful control measure can be prop- erly recommended. Although most leaf-eating beetles can be controlled with a poison spray, as used against the grape root- worm, there exists a marked difference in the time of appearance of Fig. 3.' -The grapevine Fidia {Fidia longipes): Adult or beetle.
