82 TABLE OF FAMILES OF ORTHOPTERA. 



CLASSIFICATION OF ORTHOPTERA. 



Prof. Comstock* divides this order into seven families, 

 which are grouped in live sections. Each of the first four 

 sections contain but a single family, the fifth one includes the 

 three remaining ones. The names of the sections, with the 

 exception of the first one, were suggested by the form of the 

 legs. The following are the names of the sections and ol the 

 families they include: 



I. Dermaptera ; includes the F or hculidae or Earwigs. 

 II. Cursoria or Runners; includes the Blattidcc or 



Cockroaches. 

 HI. Raptatoria or Qrasj^ievs; includes the Alantidse or 



Rear-horses. 

 IV. Amhulatoria or Walkers; includes the PZ/flSOT/c/a? or 

 Walking-sticks. 

 V. Sa/t^Jtorja or Jumpers; includes the /Icr/Vf/V/^ or Lo- 

 custs or Short-horned Grasshoppers, the 

 Locustidae or Long-horned Grasshoppers and 

 • K.\TYDIDS, and the Gryllidse or Crickets. 

 Prof. Scudder,** our highest authority on this order 

 of insects, whether recent or fossil, also arranges them in 

 the above seven families. 



With the exception of the Rear-horses (il/^nt/J^) all the 

 families are represented by one or many species. 



To enable the student to recognize the different families, 

 the following table is quoted from Prof. Comstock's Intro- 

 duction :
