Ormerod is a corresponding member of the association, and by her 
work had done much to popularize entomology in Englan 
Dr. C. V. Riley then presented two papers: n Derneriis vulpinus in 
Tobacco,” and “ Government Work gs. the Patent Office.’’ The first 
paper dealt with a case of serious damage to a large cargo of tobacco 
while in shipment. It was thought the Dermestes had gained access 
to the tobacco while in shipment, and that it was not in the tobacco 
at the time of packing. The second paper presented the difficulties 
undergone by the Department of Agriculture owing to that depart- 
ment not having a lawyer to represent it in the courts. The hydro- 
cyanic acid gas treatment for scale insects in California originated with 
the department, but a man not connected with the department has 
recently received a patent on the mere technicality of using the treat- 
ment at night. In the discussion which followed it was the opinion of 
most of the members that the patent would not be valid if brought up 
in the courts. 
Prof. E. A. Popenoe, of TER gave an account of a recent out- 
break of Dissostira longipennis in that state. The outbreak has 
covered an extensive area, and much damage has been done. 
Mr. M. H. Beckwith, of Delaware, presented some interesting 
‘ Notes on a Corn Crambid.’™ In some localities much injury has 
been done. 
Prof. J. B. Smith next presented two papers, one on ‘‘A Note on 
the Habit of Saperda candida,” and the other, ‘‘ Notes of the Year in 
New Jersey.’ The latter consisted of an account of the principal 
insects which have caused injury in New Jersey the present year. 
Mr. L. O. Howard presented an interesting paper on ‘‘A Note on 
Parasites.’ Several new genera and species were exhibited. 
Prof. Herbert Osborn presented a joint paper by himself and Mr. 
H. A. Gossard on ‘‘ Experiments with the Hopperdozer for Grass-Leaf 
Hoppers.’’ The paper gave the results obtained with this machine in 
Iowa this season. The hopperdozer was said to be an excellent agent 
in the destruction of the leaf hoppers. 
Another paper, on “ The Clover-Seed Caterpillar,” by the same 
authors as the above, was read by Prof. Osborn. This insect has been 
very numerous at Ames this year, and has proved very injurious. 
paper upon ‘‘ Notes ‘of the Season in South Dakota’’ was read by 
the secretary from Mr. J. M. Aldrich. Grasshoppers have appeared 
in large numbers in this state the present season, but by the constant 
use of hopperdozers many are killed, and fall plowing is practiced in 
order to kill the eggs.
