costigma] are much less abundant than last year. In most cases 
where injury is being done, the cause is neglect to remove the egg 
masses. The larvae of Prionoxystus robiniae and those of 
Cyllene robiniae have destroyed nearly all the honey locust 
trees in the city, and on June 29 an adult of the former species was 
taken. June 30. Neoclytus erythrocephalus was observed 
July 4 ovipositing on a dying tree, Tilia americana. Phy- 
toptus quadripes was so numerous on silver maple as to cause 
many leaves to wither and fall. The young larvae of Prionoxystus 
robiniae were found the same day in great numbers boring in the 
bark of oak trees, and adults of Saperda candida were taken on 
mountain ash (Pyrus sorbus) and on Paul’s thorn (Crataegus 
oxyacantha var. paulii); this insect has nearly destroyed these 
trees in Buffalo. July 2 the larvae and pupae of Cryptorhynchus 
lapathi were taken from a Carolina poplar, and more recently the 
same stages were secured in Salix babylonica. The adults 
have been taken on Salix alba. White-marked tussock moth 
[Notolophus leucostigma] is now in the pupal state, no 
adults having been seen. July 13. Many Carolina poplars are being 
destroyed by Cryptorhynchus lapathi. Larvae of Agrilus 
anxius were found in the pupal cells July 14; young larvae about 
Y inch long were found July 1g feeding in the cambium layer, and _ 
had then traveled some distance. On investigating the cases of human 
injury attributed to the bite of the “kissing bug ”, it was learned that there 
were a number of sufferers and that examples of Opsicoetus per- 
sonatus were readily found in the localities where most of the people 
were bitten. Adults of Saperda calcarata began to emerge 
from Populus monilifera July 18. This species is very destruc- 
tive to the cottonwood and has been taken from other poplars. July 21. 
One prominent physician took fourspecimensof Opsicoetus per- 
sonatus inhis house. Every case which has come under my obser- 
vation, since my last report, has been correct as regards the sting; the 
persons whom I have seen relate that they were bitten at night. White- 
marked tussock moth caterpillars [Notolophus leucostigma | 
have nearly all spun up and a number of egg masses have been deposited, 
From 85 to 90% of the whole brood has been destroyed by parasites, 
Pimpla inquisitor being the principal parasite; the next a 
Chalcis, which I believe tobe C. ovata, with Pimpla con- 
quisitor anda Tachina fly ranking after in importance. July 
28. Agrilus anxius has been found thoroughly infesting black
