As a curiosity it may be noted that Cetonia metallica, by attacking 
potato stalks and leaves, caused alarm and was sent in for examina- 
tion, as it was suspected to be ‘the terrible Colorado potato-beetle” 
from America. We have, however, another beetle which occasionally 
attacks the potato plant in our country, viz, Adimonia tanaceti. 
Besides many of the well-known apple pests, such as Anthonomus 
pomorum, Carpocapsa pomonella, several leaf-destroying tortricids, 
Phyllobius pyri, Phyllopertha horticola, Psylla mali, Aphis mali, ete., we 
have, especially in the western “ fiord districts,” a most serious enemy 
to the apple trees in Telephorus obscurus (and some allied species), which 
occurs in immense numbers and totally destroys the apple blossoms by 
eating them away as soon as they begin to open. Spraying with Paris 
green kills a great many of them, but their numbers are often quite 
overwhelning. 
The chief enemy of the pear is Phytoptus pyri, which is often most 
troublesome, ‘‘bladdering” the leaves to such an extent that not a 
single one can be found untouched. 
Gooseberry and currant have suffered very much from the attacks 
of Nematus ribesti (ventricosus), which in the past year occurred in unu- 
sually great numbers throughout the country, defoliating, especially, the 
gooseberry. The berries of the latter have also been damaged by 
Zophodia convolutella. 
Rose leaves have been to a great extent sucked and discolored by 
Typhlocyba rose. Aphis rose and Tetranychus telarius are common 
pests. 
Among the insects on forest and shade trees may be named as havy- 
ing caused injuries in different parts of the country: 
PINE: Hylurgus piniperda, Lophyrus rufus, Bupalus piniarius, Ceci- 
domyia brachyntera, Tetranychus sp.; LARCH: Orgyia antiqua and 
Bombyx rubi; Brrcu: Two different species of Nematus larvee (from 
Finmark); SORBUS AUCUPARIA: Hyponomeuta variabilis; PRUNUS 
PADUS: Hyponomeuta padi; and ALNUS INCANA: Apoderus coryli. 
NOTES FROM MARYLAND ON THE PRINCIPAL INJURIOUS INSECTS 
OF THE YEAR. 
By WILLIS G. JOHNSON, College Park, Md. 
The first insect of the season that attracted any considerable atten- 
tion throughout the State was the clover-leaf weevil (Phytonomus pune- 
tatus). The larve were first observed by me here at the station on crim- 
son clover April 14, but no complaints of injury by them were reported 
to me until April 22, at which time Mr. H. O. Devries, of Marriottsville, 
Howard County, wrote that they had appeared in the clover fields in 
his vicinity ‘“‘ with renewed vigor.” Other reports came almost daily of 
their avrival, in great abundance, in the counties of Montgomery, How- 
ard, Washington, Frederick, Carroll, Harford, Baltimore, Anne Arun-
