being wingless and feed on cactus. Digger wasps are very com- 
mon especially ‘velvet ants,” sometimes called “cattle killers.” 
Butterflies are very rare. The speaker stated that he took only 
one common species on his collecting trips. He collected an 
abundance of geometrids. Agricultural ants were very abun- 
dant and ciccadas were also quite common. Mosquitoes were 
found only within a belt of 5 miles of the Rio Grande Valley. 
Moisture is very scant. The light (8 in.) rain comes during

_ Mr. Walker presented the paper of the evening on “A Sum- 
mer’s Collecting of Orthoptera in Florida.” He discussed and 
exhibited the characteristic orthoptera of the salt marsh, sand 
scrub, sandy ponds, cypress ponds, low pine woods, high pine 
woods, flat woods, and hammock. The new species collected 
brings the total number for Florida to 208. Of particular in- 
terest was an undescribed grasshopper from the sand scrub. 
Mr. Walker described the methods used in collecting. He em- 
phasized the fact that many species not to be found at all, or 
rarely, during the day could be readily taken at night.
