INSECTS AFFECTING PARK AND WOODLAND TREES 43 I 



An olive, gray-mottled beetle with black head and thorax and about inch long, occurs 



in early spring on partly decayed beech stumps

 A brown-headed, black-wTnged, rather stout beetle about '4 inch long, was bred from 



larvae taken from a hollow oak Dermestes p u 1 c h e r, p. 489 



For less important species taken under decaying bark or in decaying wood, see p. 489-494 



Fungous beetles 



There are a number of species formed on various fungi growing on trees, and some of the 



more common are noticed briefly on p. 494 

 Natural enemies of one kind or another are frequently found in association with the 



above named species, and they are noticed briefly on p. 499-505 



Beautiful hickory borer 



Goes pule fir a Hald. 



A stout beetle about an inch long and beautifully marked with dark brown, silvery 

 and reddish yellow bores in hickory. 



The parent insect is a stout beetle, about i inch long, beautifully 

 clothed with dark brown, silvery and reddish yellow pubescence. There is 

 a broad, transverse, lighter band across the wing covers, and the tips of the 

 latter are conspicuous on account of the golden pubescence covering them 

 [pi. 9, fig.i]. 



This insect deposits its eggs on different varieties of hickory, frequently 

 selecting smaller trees only an inch or thereabouts in diameter. The opera- 

 tions of the grub inside young trees, causes the trunk to enlarge so that 

 there is produced a gall-like swelling, which weakens the tree and may result 

 in its breaking off in a gale. Old borings are marked by an ugly wound 

 [pi. 9, fig. 3], Recent operations of the larva are shown at figure 4, its 

 characteristic feedings at the base of leaf stems and the exit hole of the 

 parent beetle are represented at figures 2 and 5 respectively, plate 9. 



This species is not abundant in New York, if one may judge from the 

 condition of the State collections. This may be due in part to the retiring 

 habits of the adults. It was reported a number of years ago by Dr Hodge 

 as scarce, though found every season in shagbark and pignut hickory, about
