The above is only a brief description of the species occurring in the writer's collec- 

 tion. It is not by any means a complete list of the family Acrididae in Nova Scotia, as 

 there are some species reported that the writer has not seen, and there is a possibility 

 of some being in the province which have never been reported. 



EXPLANATION OF TERMS. 



As the members of the Acrididae are all comparatively large species, this group af- 

 fords an attractive field of work for beginners in entomology. In order to render the 

 terms used in the foregoing article more intelligible to those who might wish to follow 

 this subject further, and have not had the advantage of special entomological training, 

 the following explanations are given and should be used in conjunction with the plate.

Apical margin — Pertaining to the apex. See Fig. 5, b. 



Carina — A ridge or keel on pronotum. See Fig. 7.

also Fig. 11a.
