Caffrey, of the Maxwell, N, Mex., station, reports an unusual scarcity of 
yae of Hemileuca this season. A long period of drought has apparently re- 
in the prevention of the hat¢hing of the eggs of the range caterpillar. 
Caffrey is having great difficulty in securing enough caterpillars to furnish 
Or rearings of the predaceous enemies of the range caterpillar. The heads | 
id stations of this branch are therefore asked to send to Mr, 
€¢y lepidopterous larvae of any kind which may be used as food for 
oSema bectles or as hosts for Tachinid fly Compsilura concinnata. 
iS6 larvae should be packed in such a way as to reach Mr, Caffrey 
lv6 and in a8 good condition as possible.
