34 PEELlMIISrARY EEPOET ON ALFALFA WEEVIL. 
A NATIVE TRUE PARASITE. 
Only one specimen of a single species of a true parasite of the alfalfa 
weevil has so far been found in America. This Avas described by 
Mr. Viereck as JEnoplegimorplia pliytonomi. It was found August 30, 
1911, at Hoytsville, Utah/ in the form of a cocooned pupa within the 
cocoon of the alfalfa weevil. The specimen was picked up from the 
surface of the ground in a badly infested alfalfa field and the adult 
parasite reared. The adult emerged September 3. 
INTRODUCED PARASITES. 
Several species of parasites were sent over from the vicinity of 
Portici, Italy, by Mr. W. F. Fiske during April, May, and June, 1911.

The egg parasites were obtained by collecting stems of alfalfa con- 
taining eggs of -the alfalfa weevil, placing these in boxes (PI. X, fig. 3), 
and transporting them by cold storage on steamers bound for New 
York. On arrival from Europe they v/ere promptly forwarded by 
refrigerator express to their destination, Salt Lake City, Utah, where 
they were at once taken either to the laboratory at Salt Lake City 
(PL XIII, fig. 1) or to the laboratory at Murray (PL XIII, fig. 2). 
Parasites that attack the weevil after it has hatched and before it 
has developed to the adult were handled in much the same manner. 
The boxes in which they were consigned are shown in Plate X, fi.gure 
2. The time required to transport these boxes from Portici, Italy, 
to Salt Lake City, Utah, was from 16 to 21 days.
