S. &. Rohwer, Entomologist, in Charge 
In the autumn of 1924 Dr, William Schaus leerned from his friend end 
colleague Paul Dognin that the collection of Lepidoptera belonging to the 
jJatter would be offered for sele. Mr. Dognin formed this collection during 
his 40 years' active work as e lepidopterist, nd it seemed to him ‘advisable 
Pewercanee the finel disposition of this veluable collection before th 
Cessation of his opportunities to work. The collection contains about 
SOPOOO Specimens of lepidoptere, of which 82,000 are spread, oand includes 
Bepernor 5, 500 Species known to occur in the New world. Mr. Dognin set for 
the collection the price of $50,000, and out of friendship he gave Dr. 
sehaus an opportunity to purchase it, provided he could raise this amount 
before the end of March, 1925... Dr. Schaus immediately began an active canvas 
for the necessary money and by vigor end perseverance was successful. The 
Doeoin Collection of tlepidoptera will be one of the finest recent additions 
to the rapidly growing collection of insects in the National Museum, end samer- 
je¢an entomologists should be “deeply grateful to Dr. Schaus for his service 
Seeoeieins 1+ to America. 
Dr. Sehaus and his friend J. T. Barmes will sail for‘Europe early in June 
to arrange for the packing of the Dognin collection and its transportation 
Soummerace, Dr. Schaus expects to study types of Lepidoptera in Berlin, 
then proeeed to London, where he will compare material with the types in 
the British Museum. By way of preperation Dr. Scheus has picked out over 
5,000 Specimens of Oriental and Africen moths from tke National Colleetion, 
Which are being sent to the British Museum for this comparison. It is 
Expected thet the trip made by Dr. Schaus and Mr. searnes will occupy about 
five months. Dr. Scheus will beer the expense of this trip, but during tine * 
time he is pr ne in Europe he will be on pay Status.
