striking distance. Yet another up and down the roadside slopes just 

 before reaching Sus, no possibility of reaching it, however, and after 

 seeing it disappear and reappear three or four times I start to walk on, 

 whilst a friend, more patient, waited for yet one more turn, and, as the 

 big-looking creature swung in reach, quick as lightning it was 

 struggling in the folds of the net. It was our last recollection of Sus, 

 for we had arranged on the 10th to be back about 4 p.m., and when 

 we arrived preparations for going were hardlj' completed before a local 

 steed was ready to convey us to our next stopping-place. 



Synopsis of the Orthoptera of Western Europe.

Genus III : Gryllodes, Sauss. 



Brunner remarks that this genus differs from Gryllus more in its 

 general appearance than in any particular character. The head is 

 round and prominent : the eyes are small ; the pronotum somewhat 

 widened behind (in Griillus the pronotum is always a trifle narrower 

 behind). The elytra, in the $ , are as long as the abdomen, but very 

 short in the 5 . The front face of the anterior tibite has no 

 tympanum. 



AH the species are natives of the Spanish Peninsula. Owing to 

 their pale colour, crepuscular habits and great activity, they are 

 exceedingly difficult to capture.
