It is opened and then chipped suddenly together about the insect 

 \vliich is held tightly between the two pieces of gauze until re- 

 moved. Many Orthoptera can also be taken by beating into an 

 open umbrella, but quick action is usually necessary to capture 

 the specimen after i! is once in the ungainly receptacle. 



.Most of the ground crickets hide by day in burrows or beneath 

 slop.es, loi:s. piles of dead leaves or other debris, while roaches 

 hide beneath loose bark or behind signs attached to trees. These 

 nocturnal forms can usually easily be taken by overturning their 

 cover and capturing with fingers or forceps. .Mole crickets may 

 often lie found beneath a stone or chunk at the end of their bur- 

 rows, or by digging with a spade or trowel into the muck about 

 the border of a lake or pond. 



TitAi'Pixc; .TAKS. W. T. Davis and others have had much suc- 

 cess in taking camel-crickets (Ccutliophilus) and other terrestrial 

 species by trapping wilh a special molasses bait. This bait is 

 made by taking a pint of cane or New Orleans molasses (not corn 

 syrup i and adding to it a teaspoonful of fusel oil. Into an old 

 tin or wide mouthed jar or bottle this bait is poured to a depth of 

 about one-third of an inch. The jar is then sunk in the ground 

 to the level of its mouth and a chip or flat stone placed at an in- 

 cline just above it to keep out rain or falling debris. If visited 

 two or three times a week many insects will be found Avhich, when 

 removed with forceps into a box, then thrown into water for half 

 an hour and afterward dried, will be ready for mounting. These 

 traps are most successful when placed along woodland paths, bor- 

 ders of fields, near an old log, a pile of stones or base of a cliff, 

 especially where dead leaves or other debris occurs in quantity. 



NIGHT COLLECTING. Many rare species of nocturnal Orthop- 

 tera can best be captured by using a flash light or small camp 

 acetylene lantern after night. They will then be found moving 

 freely about over foliage or along pathways. Many can be located 

 by their night song. By taking two cross-bearings, thus closely 

 approximating the exact locality of the singer, it can be cautious- 

 ly approached and captured with net or hand. Numerous spe- 

 cies of Orthoptera are attracted by light, and good night collect- 

 ing will often be found at the proper season beneath or near the 

 electric street lights of cities and towns. 



KILLING BOTTLES. After capturing a specimen for a cabinet 

 it is best to kill it as quickly as possible before its antenme, legs 

 or other delicate appendages are broken. This is best accom-
