and in the « Proceedings of the American Entomological Society ». 
At the present time his successors are doing good work, and the 
names of FALL, FucHs, BLAISDELL, VAN DYKE and WRIGHT 
are well known. The Pacific Coast Entomological Society 1s active 
and efficient and doubtless has a great future. Dr. BEHR's first 
paper in this country was published in 1855, and in the next ten or 
twenty years a number of men commenced to contribute to the 
science, and while they were by no means a large army, the study 
was being pursued in a number of places. 
In 1861 Prof. P. R. UHLER had commenced his valuable studies 
on the Hemiptera, which has been his life work so far as entom- 
ology is concerned. In 1869 Dr. A. S. PACKARD gave to American 
entomologists his « Guide to the Study of Insects », and no serious 
student of the subject was without this work. He was a prolific 
writer, and we can only mention his « Text-book of Entomology » 
and his « Studies on the Bombycine Moths ». In 1867 a man com- 
menced to write on the Noctuidæ. I refer to A. R. GROTE of 
Buffalo, New York. He was an untiring systematist and described 
a considerable portion of our species in the family. 
In the late fifties that indefatigable author SAMUEL H. SCUDDER, 
whose many contributions to entomology mark him as one of our 
greatest students, commenced his work. His work on the Ortho- 
ptera, his « Butterflies of the Eastern U. S. and Canada » and his 
works on fossil Insects will make his name immortal in entom- 
ology. 
Another Pennsylvanian who acquired a great reputation was 
Dr. HERMAN STRECKER of Reading. He was probably known to 
every collector of Lepidoptera the world over and amassed an 
enormous collection, which now adorns the Field Museum of 
Natural History in Chicago. 
In 1878 he published his « Butterflies and Moths of North 
America » and in 1872 commenced his illustrated work entitled 
« Lepidoptera, Rhopaloceres and Heteroceres ». The last parts did 
not appear until 1900. 
In the early sixties, WM. H. EDWARDS, one of the world's 
greatest lepidopterists, commenced writing and describing species 
and life-histories and did splendid work for more than thirty years. 
His publication on American Butterflies has never been surpassed, 
either as to the value of the contents or for beauty and accuracy 
of the illustrations. When he began there was very little known of 
the stages of our American Butterflies.
