Insects Visiting Blossoms of Spirea 125 
berry blossoms. Of these two, one was from a spirea 
blossom, while the other was taken June 22 from the surface 
of a beech log felled three years before. Of the twelve speci- 
mens taken in 1917, eleven of which were from flowers, eight 
are of the testaceous variety known as variety luridipennis. 
L. mutabilis has been bred from a small branch of a dying 
alder obtained near Syracuse, and Mr. Carl Wright, a stu- 
dent in the college, has taken a specimen of the testaceous 
form from the wood of hemlock at Cranberry Lake, N. Y. 
Apparently it has a variety of hosts. 
Leptura pubera Say. The seasonal distribution of this 
species nearly coincides with that of L. mutabilis, but extends 
slightly later. Specimens were numerous upon blackberry 
blossoms until the appearance of the spirzea blooms, when 
they showed a very marked preference for the latter. Dur- 
ing the first three weeks in July this species was decidedly 
the most common lepturid. In 1914 several specimens were 
taken from daisy heads. 
Leptura sphericollis Say. But three specimens of this 
species were taken in 1917, two from wild blackberry in the 
first week in July and one from mountain azalea on June 20. 
These all are of the typical form with the black prothorax. 
Three specimens were also taken in July, 1914, of which two 
are of the typical coloration and one has the red prothorax 
characteristic of the variety ruficollis. 
Pachyta monticola Rand. But one specimen of this lepturid 
was taken during the last season and it was obtained from 
a blackberry blossom on July 3. The only other specimen 
taken by the author from this same general region was from 
the bark of recently felled balsam tree, July 8, 1914. No 
breeding data is available, but it is believed the specimen 
captured on balsam was preparing to oviposit. Wickham 
(1897, p. 171) records the adult from the blossoms of wild 
rose. 
Leptura lineola Say. This species, which in the region 
studied is never one of the most abundant lepturids, has a 
seasonal distribution extending over July, the maximum
