Lepidoptera, Mr. Williams exhibited some species of day-flying 
moths. 
Diptera. Mr. E. T. Cresson, Jr., exhibited a small collection of Dip- 
tera presented to the Society by Mr. F. M. Jones, of Wilmington, Del., 
and collected by the donor in western United States and Alaska. Altho 
the collection contains only 95 specimens, it represents 49 determined, 
and about 17 undetermined species; ten of these are new to the collec- 
tion, four of which were described as new to science. Particular attention 
was called to the excellent condition of the material. Special attention 
was also called to two of the new species. One belonging to the Leptid 
genus Arthropeas which contains only two other American species, differs 
from all known species by the entirely black legs and is further charac- 
terized by the globose facial swelling. The other species, belonging to 
the Tabanid genus Silvius, is especially interesting in that it differs so 
materially from the other representative of the genus, gigantulus, while 
having all the appearance of some of the species of Pangonia. However, 
in the structure of the antennae and in the absence of hind tibial spurs, 
supposedly generic characters, it is certainly typical of Silvius. The 
descriptions of the new species are published in the Proc. A. N. S. P. for 
1919. 
Orthoptera. A series of Orthoptera and Dermaptera was exhibited 
by Mr. Hebard, showing the largest and smallest species of the various 
families. It was pointed out that the largest known species of Orthoptera 
is the walking-stick Phryganistria grandis Rehn, the smallest is the 
cricket Myrmecophila oregonensis Bruner. The distribution and habits 
of the various species exhibited were discussed. Further remarks on the 
subject were made by Dr. Skinner, Laurent and Rehn. 
Coleoptera. Mr. J. J. Davis exhibited, in Riker mounts, specimens 
showing the life history of the Japanese Scarabeid beetle, Popila japonica, 
and its ravages on plants (elm, willow, oak, 5-leaved ivy, fern, Norway 
maple, apple, grape, sweet cherry and smart-weed), and gave a_ short 
but interesting talk on its habits, distribution, destructiveness and the 
methods being pursued with a view to minimizing its ravages and prevent 
its spread. He stated that it seemed to be confined to Burlington County, 
New Jersey, appearing in June and continuing its activities into Septem- 
ber. It had first been noticed five years ago, multiplied rapidly and was 
hard to control; the insect in its adult state skeletonizes the leaves of the 
plant it attacks and seems to eat everything. He spoke of the efforts 
being made for its reduction, as plowing the ground at the proper season, 
hand collecting, insecticides and salting, cutting the roadside growths, a 
difficult task as there were about 200 miles of road in the infested area. 
There was discussion as to methods of capture by Messrs. Hebard, 
Skinner and Williams. 
Mr. C. H. Hadley spoke of the quarantine established against these 
beetles and stated’ that they were sun-loving, active insects and did not 
appear in woods. The infected area is now about 25 square miles.
