702 FAMILY VIII. GKYLLID.K. THE CUK'KKTS. 



Dunedin it is the most common field cricket noted, both adults 

 and nymphs occurring throughout the winter, the long-winged 

 forms, there frequent, being often attracted to light. Hebard 

 captured them in numbers on Feb. 9 ber_3ath boards and stones 

 along the main street of Miami, where "after dark they were strid- 

 ulating at a great rate." 



In Ontario Walker (11)04, 2."0) says that adults begin to ait- 

 pear about the second week in August and in September and Oc- 

 tober become very numerous and congregate in large numbers 

 under every chunk, log or board, under the loose bark of old logs 

 or in burrows in the sand. Late in the season they may be seen 

 by hundreds sunning themselves on fences close to the ground. 



About Moline, 111., according to McNeill (1801), "the eggs of 

 aljbrcridtiiK hatch in July and the first adults appear as early as 

 the second week in August. During every stage of life they are 

 social, feeding together, seeking shelter in company and when 

 egg laying time comes, in October, the females collect by hundreds 

 in some suitable locality, an abandoned or little used roadway 

 suits them well, and each lays several hundred eggs in an irregular 

 mass. After this duty is performed their business on this planet 

 seems to be finished and they succumb to the cold, none surviving 

 the winter. The eggs do not hatch until the following July, or if 

 in rare cases they do they probably perish with cold." 



Allard (lOlla, 157) says that about Washington abbrcriatiis 

 "not infrequently takes up its quarters in the house, announcing 

 its presence by its stridulations which are intermittent chirps, 

 possibly louder than the chirp of (}. pennsylvanicus."
