Suborder ACHETOIDEA. 



The crickets, although not as numerous as either the short-horned 

 grasshoppers or locusts, or the long-horned grasshoppers, are, never- 

 theless, quite abundant in both genera and species. Like both of 

 those subordersof the saltatorial orthoptera just mentioned, the present 

 group is most numerously represented in subtropical and tropical 

 countries. This statement is especially true of the more humid 

 sections of those countries where the great forests and jungles of the 

 world are to be found. In and about these they abound in great 

 variety as to size, habits, etc. Thus far the group has been less col- 

 lected and even less studied than other orthopterous insects. 



Generally speaking, the crickets are less attractive than are the 

 representatives of either of the "grasshopper" groups, because they 

 are as a rule either dull in color, or do not possess striking structural
