8 NEW YORK STATE M,USEUM 



lotte, N. C, and westward into Ohio and Kentucky. It occurs 

 in most of the cities and villages in the Hudson valley, having 

 made its way north to Glens Falls and Ticonderoga and along 

 the Mohawk valley at least to Amsterdam. It has become well 

 established at Elmira and Ithaca and has been known for some 

 years in Oswego, though it does not appear to have been par- 

 ticularly destructive in that city. There is no record known to 

 us of this species occurring in Utica, Syracuse, Rochester or 

 Buffalo, though it is rather surprising that it has not already 

 become established in all of these cities. 



Description. The skeletonized brown appearance of the fol- 

 iage in midsummer is very characteristic of the work of this 

 pest, particularly in the eastern cities and villages of the State. 

 The irregular, oval holes about one-quarter of an inch in diam- 

 eter, eaten by the beetles in early spring, are another indication 

 of the work of this species. 



The parent beetle may be recognized by reference to the 

 colored illustration [pi. i.fig. 5,6]. It is about one-quarter of an 

 inch long, with the head, thorax and margin of the wing covers 

 a reddish yellow. The coal-black eyes and median spot of the 

 same color on the head are prominent. The thorax is marked 

 with a dorsal black spot of variable shape and with a pair of 

 lateral ovoid ones. The median black line on the wing covers is 

 widely separated from lateral stripes of the same color by green- 

 ish yellow. The wing covers are minutely and irregularly punc- 

 tured, bear a fine pubescence and at the base of each there is an 

 elongated, black spot in the middle of the greenish yellow stripe. 

 These miarkings are fairly constant in the beetle, though the 

 color is quite variable during life and changes more or less after 

 death. Many of the insects emerging from winter quarters have 

 the yellowish stripes of the wing covers nearly obliterated by 

 black. 



The orange-yellow eggs [pi. i, fig. i] are usually deposited in 

 irregular rows side by side, forming clusters of from three to 

 twenty-six or more on the underside of the leaf. Each egg is 

 somewhat fusiform, attached vertically by its larger end and 

 with the free extremity tapering to a paler rounded point. 



The recently hatched grub [pi. i, fig. 2] is about one-twentieth 

 of an inch long with the head, thoracic shield, numerous tuber- 

 cles, hairs and legs jet-black. The skin is dark yellow but the 

 tubercles are so large and the hairs so prominent that the pre- 

 vailing color of the grub at this stage is nearly black. An increase
