Insects Visiting Blossoms of Spirea 131 
Leptura biforis Newn. One specimen of this beetle was 
taken July 23, 1914, from spirea bloom. Nothing is known 
regarding its breeding habits. 
Leptura vibex Newn. A single example of this species was 
taken July 10, 1914, from leaves about half way up Spruce 
Top Mountain. It is not known that this species ever visits 
wild spirea but from the great uniformity in habits shown 
by the adults of this genus it seems probable. 
Leptura aurata Horn. Two specimens were taken from 
spirea July 23, 1914. Nothing further is known regarding 
its habits. 
Only a few species of Coleoptera other than the lepturids 
already treated were taken in sufficient numbers for any 
conclusions to be drawn regarding their seasonal distribution. 
A few of these are briefly mentioned below. 
Oberea tripunctata Swed. and Oberea bimaculata Oliv. 
may be mentioned together. Two specimens of each were 
taken during the first two weeks of July, 1917, from blossoms 
of wild blackberry in the stems of which they are said to 
breed. 
Clytanthus ruricola Oliv. This cerambycid occurs at its 
maximum numbers in late July and early August at the 
heighth of the wild spirea season. While it frequents these 
flowers by preference it is also occasionally seen on the 
flowers of the daisy, golden-rod and others. A number of 
specimens of this form have been bred from hickory at Syra- 
euse but no hickory occurs in the Elka Park region and it 
must depend upon some other wood. In one case a specimen 
was observed which was apparently preparing to oviposit in 
‘beach and it is probable this serves as a larval host. 
Chaulignathus pennsylvanicus DeG. is well known to be 
a late season form. It appears about the middle of August 
and does not occur in great numbers until the spirea blos- 
soms are decidedly on the wane and the golden rods are at 
their maximum. For that reason much larger numbers are 
to be seen on golden rod than upon spirea, Yet in spite of 
this it will be seen from the table that the specimens actually
