the National Museum it seems that the insect was collected at Palmer. 
Utah, in July, 1869, which is evidence that it must have been intro- 
duced many years earlier. In 1873 it was found in central Missouri. 
It has been taken by Messrs. Dyar and Caudell in Denver, Salida, and 
Sedalia. Colo., by Cockerell on the top of the range between Sapola 
and Pecos rivers in New Mexico at about 11,000 feet elevation. It is 
also recorded from Winnipeg. Manitoba, as well as from several 
localities in Nebraska. Kansas, and Michigan. It does not appear to 
have been observed in Illinois, although search has doubtless been 
made for it on sugar beets cultivated in that State. Dr. Dyar, in a 
note to the writer, generalizes that the species is rather common 
throughout the Rockv Mountain range. 
Meyrick records this species as inhabiting England. Ireland, western 
and central Europe, and northern Asia, as well as North America, 
and mentions its occurrence on the upper side of the leaves of Arte- 
misia vulgaris and eampestrix. Kaltenbach also records Artemisia as a 
food plant.

There seems no reasonable doubt that we have another case of 
introduction from Asia into the Pacific States of this country, analo- 
gous to that of the beet army worm treated in preceding pages. There 
is this difference, however, that the present species was introduced 
many years earlier, has a much wider range, and is capable of sustain- 
ing life in several zones, from the Lower Austral, perhaps to the 
Transition. There is no doubt about the establishment of the species 
in the Colorado localities, but larvae do not appear to have been 
observed in the localities mentioned in New Mexico and Manitoba, 
which are obviouslv transitional. 
THE IMPORTED CABBAGE WEBWORM. 
(HeUula undcUis Fab.) 
Up to November 19. 1900. only one complaint of injury effected by 
the imported cabbage webworm reached this office, It was. however, 
reported from a new locality in Georgia by Mr. H. Walter McWillianiv,
