Messrs. Benton, Caudell, Couden, Barber, Dyar, Heidemann, 
Hopkins, Patten, Pratt, Titus, Ulke, members, and Messrs. 
Clemons, Knab, Pinkus, and Ulke, Jr., visitors. 
Mr. Titus was appointed to act as Recording and Correspond- 
ing Secretary during the absence of Messrs. Currie and Benton. 
Mr. Barber exhibited specimens of Spharidium scarabce- 
oides and a map showing its present distribution in America 
and presented the following notes: 
THE SPREAD OF SPHjERIDIUM SCARAB^OIDES LINN^US. 
(COLEOPTERA, HYDROPHILID^E.) 
BY H. S. BARBER. 
The Genus Sphaeridium is included in LeConte and Horn's 
Classification (1883) but with the following footnote: "A 
specimen of the European Sphceridium scarabczoides has been 
found in Canada. The species is undoubtedly introduced, and 
accidental in occurrence . . . . " The name is included 
in Henshaw's Check list, 1885. 
In 1893 Mr. G. Chagnon, of Montreal, Can., published 1 
the following note: "Sph&ridium scarabczoides, which has been 
introduced from Europe, is now very common here. I had the 
pleasure to send several specimens to Dr. Geo. H. Horn." 
The next mention of its capture that I can find is by Mr. 
C. O. Hough ton, in 1 898,2 where he records its occurrence at 
Potsdam, N. Y., in 1896, and gives an account of the habits. 
Entomological News, Volume XII, 1901, has four notes on 
this species : R. F. Pearsall (p. 158) mentions LeConte and Horn's 
note, and records the capture in the Catskill Mts., N. Y., in July, 
1900. C. O. Hough ton (p. 209) records it from Ithaca, N. Y., 
in May, 1901 ; Mr. Luccareni (p. 256) from Split Rock Pond, 
Morris Co., N. J. (probably 1901?) and G. W. Caffrey (p. 296) 
records it from Bethlehem, Pa., May 28, '01. 
Mr. Schaeffer gives a note concerning its spread, 3 recording it 
from West Farms, N. Y., and also mentions Wisconsin and 
Canada. 
Mr. Pratt took the species abundantly at East Providence, 
R. I., in August, 1903. 
Mr. Dickerson reports it 4 from Chester, Morris Co., N. J.,
