NES ITEMS FROM THE HAGERSTOWN (.) FIELD STATION. 
The light trap has been run at this station every night throughout the summer 
a but few exceptions when heavy storms interfered. The first appearance of the 
Otton-worm moths (Alabama erst? laces) was ceptember 28 when 7 motns were ¢col- 
ed at the trap-light. No other flights of this insect have been observed at . 
S point. On the same date, 11 army-worm moths (Cirphis unipuncta) were taker, 
nich is this season's last record for this moth. 
a A cheap apparatus for the control of environmental factors for experimental 
fork with insects has been constructed at this station and has proved quite satis- 
ory. The apparatus consists of a galvanized iron box 10" x 14" x 24" with sol- 
red joints and hinged glass door on one side, which accommodates a selfrecording 
mnermohygrograph. In one end is a small sliding door for the introduction of the 
Srial to be experimented upon and a small hole near the bottom for the introduc- 
of the tube from the drying apparatus. In the top is a small hole for the ine 
duction of moisture apparatus and another for the thermostat. In the other end 
‘the top is a hole in which a funnel has been soldered to serve as an air 
Rhaust. A circulation of air is forced through the drying apparatus, which consists
