We have adopted Ollvier's order Orthoptera, because we 

 conceive that insects which bite their food are essentially 

 distinguished from those that take it by suction. This 

 order includes such of the Linnsean Hemipterous Genera 

 as are furnished with maxillse ; viz. Blatta, Mantis, and 

 Gryllus, leaving in Hemlptera those insects only that take 

 their food by means of a rostrum. The learned Scopoli, 

 led by this circumstance, had long since united the above 

 genera to Coleoptera ; but from that order they are evidently 

 distinct, not only on account of the different substance of 

 the elytra, but likewise by the mode in which they fold 

 their wings; Coleopterous insects folding them transversely, 

 while those in question fold them longitudinally. Olivier's 

 characters of the two orders Orthoptera and Hemlptera are 

 as follows :
