Mr. W. R. Thompson, who has during the past year been engaged 
m collecting and forwarding parasites of the alfalfa weevil, has 
resigned to take up a course of study in the University of Paris. 
de will, however, continue his connection with us as collaborator. 
Two tachinid parasites of Plathypena scabra have been reared 
recently at the Greenwood station by Mr. E. H. Gibson. Neither of 
them has before been recorded from this host. They are Cuphocera 
ruficauda and Neopales flavicauda V. d. Wulp. 
q Experience during the last two seasons has shown that ordinary 
tin tomato cans are preferable to earthenware florist pots for 
Carrying insects on growing food plants. The plants thrive much 
better and seldom need watering. The Hawaii Station has discarded 
the pots for cans for growing seedling plants. GEO. G. AINSLIE. 
Mr. Wildermuth has succeeded in rearing the tachinid fly, 
Compsilura concinnata from the larva of the range caterpillar 
({Hemileuca oliviae). This is one of the imported enemies of the 
gipsy and brown tail moths, material for this experiment having 
been supplied by Mr. Burgess from the gipsy moth laboratory at 
Melrose Highlands, Mass. 
The discovery of alfalfa weevils, in potatoes shipped in re- 
Utah, laboratory, who has been stationed for some time at Denver, 
Colo., charged with the examination of all such freight cars 
Consigned from within the area covered by the weevil. There were 
very few individuals in any of the cars. 
The rhynchophorid beetle Centrinus penicellus has been found 
breeding very generally, throughout the southeast, in the stalks of 
corn. The egg is placed in the stalk, at the base of the tassel, 
@nd the'larva works downward, usually to the second node, where it 
will be found about mature in early October, forsaking the stalk 
Tor the ground in late fall or early winter. I would like to get 
records of the presence of this beetle or its larvae from other 
localities. GEO. G. AINSLIE. 
During late October the Range Caterpillar Investigation Camp, 
near Koehler, New Mexico, was discontinued until the opening of the 
investigation next spring. The equiptment has been stored and the 
men distributed to other field stations. Despite the unusually dis- 
couraging weather conditions, the results of the season's work have 
been very encouraging and all has been accomplished that could have 
been expected. We shall begin another year with a great deal of 
the preliminary work out of the way, in excellent shape to follow 
out projects which it has not been possible to take up at all this 
year 
frigerator cars, has been duplicated by Mr. Miles of the Salt Lake City,
