ANNUAL REPORT OF NEW TORK 
HAIRY-NECKED ROSE-BUG. ITS LOCALITIES. 
bug, Macrodactylus subspinosus, with details of its history and habits. In 
the eastern section of the State of New York, there usually occurs associ¬ 
ated with this insect, individuals which we must regard as a second 
species, differing from it merely in having short stiff hairs upon its thorax, 
jutting up from the smooth surface like the beard upon a man’s face, this 
beard being of a buff-yellow color, and differing also in the relative 
dimensions of the thorax, it being rather more wide than long, whereas in' 
the common species its length slightly exceeds its width. Of the seven 
specimens just received from Saratoga County, two are of this kind. This 
hairy broad-necked species has generally been confounded with the other. 
Dr. Bunmeister was the first to point it out as being distinct,, and he 
supposes this to be the real subspinosus of Fabricius, and accordingly 
describes the smooth narrow-necked species under the name polyphagus, 
which had been applied to it in Melsheimer’s Catalogue. Dr. Le Conte, in 
his synopsis of the Melolonthidee of the United States, published in the 
Journal of the Academy of Natural Sciences cotemporaneously with the 
appearance of my Second Report, follows Burmeister in applying the 
Fabrician name to this hairy-necked species, and adopts for the smooth¬ 
necked species the name angustaius, heretofore given to it by Beauvois. 
And he supposes the two species to inhabit wholly distinct sections of our 
country, assigning New York as the locality of the hairy-necked beetle 
whilst the other is found only in the Southern States and Kansas. But 
different correspondents have sent me the smooth-necked species from 
different parts of the State of New York, from Massachusetts, Rhode 
Island, Pennsylvania, Maryland, Virginia, Ohio, Illinois, Kansas, and the 
Indian Territory south of Kansas. It is perfectly evident, therefore, that 
this species is not limited to the South and West, as Dr. Le Conte supposes, 
but occurs throughout the Northern and Middle States also. On the other 
hand, the hairy-necked species has never been found, that I am aware, 
except in the State of New York. My specimens of it are from the city of 
New York, from Albany, from the neighborhood of Utica, and from Wash¬ 
ington and Saratoga Counties. So far as yet appears, therefore, this 
species occurs only in the valley of the Hudson River and its tributaries. 
As Dr. Le Conte cites Dr. Harris’s Treatise as describing the hairy-necked 
species he must evidently infer that this species inhabits Massachusetts 
also. But this citation was probably made without due attention to the 
description of the insect given by Dr. Harris. Though he does not state 
whether the thorax of his insect is smooth or bearded, he says this part of 
its body is long and narrow, which precludes us from regarding it as this 
species, in which the thorax is wider than long. And knowing as we do 
that the smooth-necked species occurs in Massachusetts, we cannot doubt 
it was this which Dr. Harris had before him; as it was also the species 
from which the description given in my Second Report was drawn, as will 
be evident by reference thereto. 
The question now remains, was I correct in pronouncing this smooth 
and narrow-necked species to be the subspinosus of Fabricius, or are Drs. 
Burmeister and Le Conte correct in applying this name to the bearded and
