REPORT OF THE STATE ENTOMOLOGIST 



409 



Dr. Fitch, in his Third Report on the Insects of New York, has 

 described it as "pale, dull yellow, with the thorax black, except on each 

 side and on the middle of its hind edge; the hind part 

 of the head, the scutel and under side of the body 

 being also black, with the abdomen brown or sometimes 

 dull yellowish." 



The great range in variation in color of the individuals ^^inigrapevJne 

 of this species ascribed to it, is in all probability largely Li-cicoL^After 

 sexual. Two males of the examples received were in tfiove-.) 

 entire accord with the description of Dr. Fitch above given. 

 The remaining seven were females, and had the thorax yellow 

 and concolorous with the elytra, except a small black spot on each 

 side in front (as has also the male in its yellow margin), and 

 another black spot centrally and more or less distinct, near its hind 

 margin. The wing-covers are narrowly margined wiih black or brown. 

 The abdomen beneath is yellow. 



Description. 



Ai a farther ail to identification when detected feeding upon the 

 foliage of the grape,, the following is copied from Dr. Horn's " Notes 

 on the Species of Anomala Inhabiting the United States," loc. cit., pp. 

 157-164. 



Form oval, robust; color variable from entirely yellow to entirely 

 black; head moderately densely punctured; clypeus transverse; sides 

 very little divergent, angles rounded, margin in front narrowly reflexed, 

 thorax convex; sides regularly arcuate, gradually narrowed to the 

 point, basal marginal line obliterated, surface rather coarsely but not 

 densely punctured ; elytra with moderately deep striie of rather coarse, 

 clo^ ly-placed punctures, the intervals nearly equally convex ; pygid- 

 ium sparsely punctured ; body beneath coarsely but sparsely punc- 

 tured; the pectus very slightly hairy. Length, .35-. 40 inoh; 

 9-10 mm. 



The front claw of the anterior and middle tarsi is deeply cleft at tip, 

 the two portions nearly equal. 



Habits and Destructiveness of the Beetle. 

 The beetle is noted for its fondness for the foliage of the grape. 

 Dr. LeBaron, in his First Report on the Insects of Illinois, has 

 recorded their destructiveness and habits, particularly that of their 

 peculiar flights. They were noticed at about sunset on an evening 

 during the latter part of June, flying close to the ground in a zig-zag
