chemicals and as a preparation room for museum material. Extending across the 
south end of the wing is a laboratory 30' x 16'. It has two windows to the east, four 
to the south and two to the west, being splendidly lighted. This will be equipped with 
tables, electric ovens, water, sink, etc. On the west side of the hall-way is a museum 
and collection room, 33' x 16', with six windows to the west. It is planned to use this 
for economic exhibits, life history displays, and such museum material as will interest 
and instruct visitors. The systematic collections and Schmitt boxes will probably be 
kept in the library room. In the basement there is a large room extending the width 
of the entire wing, 25 or 30 to 40 feet in depth, in which can be stored insecticides and 
heavy material and types of spraying machinery for the education and instruction of 
the public. At a short distance from these quarters a greenhouse and insectary will 
be constructed within a year or two. 
The foreign gipsy moth ( Porthetria dispar L.) parasite investigations have been 
continued during the season of 1924. Messrs. S. S. Crossman, R. T. Webber, and 
S. M. Dohanian went to Europe in the latter part of February in search of gipsy 
moth parasites for introduction into the infested area of the United States. After 
spending a few days at Paris, interviewing several entomologists, Messrs. Crossman 
and Dohanian proceeded to Spain, and Mr. Webber went to Poland and Hungary. 
Several medium to heavy gipsy moth infestations were visited in Spain, and through 
the kindness of Dr. M. Aullo, Director of the Laboratory of Forest Fauna of Spain, 
arrangements were made to use two of his field stations for the season. Mr. Dohanian 
remained in Spain during the season to carry on the investigations. Messrs. Cross¬ 
man and Webber spent most of the season in Poland, Hungary, Yugoslavia and Bul¬ 
garia. After finding suitable infestations in each of these countries, temporary field 
laboratories were established. In addition to these countries, parts of Rabat and 
Algiers in northern Africa, France, Austria, Germany, Roumania, Czecho-Slovakia, 
Sardinia and Sicily were searched for P. dispar infestations. No infestations of suit¬ 
able size for parasite introduction work were found in the latter-named countries, ex¬ 
cepting in Algiers and Rabat. Arrangements were made at Algiers to have shipments 
of gipsy moth larvae sent to Melrose Highlands during the season. At Rabat a 
heavy infestation was found, and Dr. Liouville, Director of the Institute Scientifique 
Cherifien, planned to have a study of the parasties of P. dispar made at Rabat this 
summer. Should this investigation show any valuable gipsy moth parasites present 
which have not already been introduced into America, arrangements can be made to 
carry on such work. During the spring and summer about 85,000 tachinids were sent 
to Melrose Highlands. Of these importations, about 50.000 are Parasetigena segre- 
gata Rond., and 19,000 Blepharipa scutellata R. D. These two species have only one 
generation each year, and they have been placed in hibernation at the laboratory. 
The remaining material is composed of species having more than one generation 
annually, and in most cases the adults had issued and died before reaching Melrose 
Highlands. The species involved are Sturmia gilva Hartig, Carcelia gnava Meig., 
Compsilura concinnata Meig., and Tricholyga grandis Zett. In addition a few speci¬ 
mens of Chalcis intermedia Nees, and a few cocoons of a species of Hyposoter, A pan- 
teles fulvipes Hal., A. vitripennis Hal., A. melanoscelus Ratz., were sent to Melrose. 
Also about 1,000 adults of Carabus sp., Reiche and a few Calosoma inquisitor L. were 
sent to the laboratory. A few adults of Silpha quadripunctaia L. were shipped, but 
all were dead when received in the States. S. S. Crossman and S. M. Dohanian re¬ 
turned to the Gipsy Moth Laboratory in August and R. T. Webber early in September.
