INSECTS INJURIOUS IN 1902. 49 
which were flying in that vicinity, according to the statement of 
Mr. Shugard, was caught in the trap. 
A most thorough trial of lantern traps has been made by the 
Cornell Experiment Station, to see whether they would accom- 
plish all that the advertisers claim, and any orchardist or farmer 
thinking of buying one of these humbugs is advised to read the 
Cornell bulletin before purchasing. 
This Beetle has been reported by Webster as feeding upon 
roots of carrots, by Weed as injuring corn in Mississippi and by 
Forbes as guilty of the same trick along with L. rugosa, in Hlinois 
causing the corn to wither and turn yellow about the time it should 
be maturing. 
The species under discussion was reported in 1808 as injur- 
ing corn in both Wisconsin and Louisiana. In Bulletin No. 33, 
Div. of Entomology, U. S. Department of Agriculture, F. H. Chit- 
tenden reports it as injuring the roots of Sun Flower and Sweet 
Potato in I[ll., and the roots of the former plant in Neb., also roots 
of celery, carrots and parsnips in Indiana. The same bulletin 
quotes Prof. Bruner as stating that it has been quite destructive 
to sugar beet in localities in western Nebraska. 
In view of what we know of the habits of this family I was 
not surprised to receive a letter from Mr. Shugard under date of 
Oct. 30, stating, in reply to certain inquiries mailed him, that in 
1900 “cleanings from a horse yard were spread upon this plat of 
ground to the depth of about 2 inches and the yard was cleaned 
up every 3 or 4 weeks.” He stated, further, that in 1gor a light 
application of horse manure was maae, and that in the spring of 
1902 about 3 inches of horse and cow manure was used. 
MOSQUITOES. 
A country containing as much water area as Minnesota will 
always suffer to a greater or less extent in localities with this 
troublesome pest, though it is well to bear in mind that it is not 
the deep ponds or lakes which favor its increase. In other words, 
since the larva or “wiggler” or “wriggler” as it is called, gets its 
food from the bottom and its oxygen from the surface and in con- 
sequence spends much of its time oscillating between these two
