The following account of this insect is copied from Professor Riley's 
report as U. S. Entomologist for 1884 : 
During the latter part of May last, Admiral Amnien, who is noted in Washington 
for his devotion to horticulture and arboriculture, brought us specimens of this large 
saw-ily, with an account of its injuries to his imported willows, not as usual by the 
larva, but by the gnawing of the perfect dy, the plantation being described as look- 
ing as if a fire had run over it, or as if it had suffered by a severe frost. As this habit 
was new, so far as we have any records, and as nothing was known of the mode of 
oviposition in the species, we had the matter investigated. The tips of many of the 
plants were found to be dark brown and dead; the dried-up portion extended '2 to 
4 inche8from the tip. Upon investigation it was plain that the cause of the trouble 
was a very fine but deep transverse incision just below the dead portion of the willow, 
the incision often extending more than half way around the twig, or there being a 
number of smaller incisions, one above the other. (Fig. 194, b. ) All these incisions, 
were so narrow that they could hardly be supposed to have been made for feeding 
purposes; but in many instances a number of larger marks, usually of an oblong 
shape, were visible, and looked as though they had been made for food. 
According to Admiral Ammen this iujury had been done by the saw-flies in the 
latter part of May: but on the oth of June the dies had for the most part disap- 
peared, and Mr. Schwarz, who made examination after our departure for Europe, 
found at that date but a single female, sitting on a branch of about 5 mm in diameter, 
and just in the act of cutting one of the incisures referred to above. The insect 
worked its mandibles in a very slow and deliberate manner, and made but little 
headway in cutting during the three or four minutes he watched its workings. 
Upon examination the twig was found to contain three such incisures, each reaching 
more than halfway around. 
The eggs and mode of oviposition.— Whether or not the cutting of the tips is madefor 
feeding purposes, it is evident that it has nothing to do with oviposition, as no trace
