Orthoptera 143 



probable that some at least of the three British Ectobiidae 

 occur, but records of captured Orthoptera in the county are 

 few and far between.) 



EUORTHOPTERA. 



ACRIDIODEA. 

 Family TRUXALIDAE. 



Mecostethus grossus, L. " Cambridge " (C. W. Dale). 

 Abundant in the feus round Ely; also in Burwell and Swaff- 

 ham fens, Gamlingay bogs, etc. (Jenyns). 



Stenobothrus lineatus, Panz. 



Omocestus viridulus, Linn. Common in meadows, Burwell, 

 etc. (Jenyns) ; common at Wicken Fen (Porritt). 



0. rufipes, Zett. Common at Wicken Fen (Porritt). 



Stauroderus bicolw (Charp). An abundant species in most 

 places, Burwell, etc. (Jenyns); abundant at Wicken (Porritt). 

 This species is exceedingly variable in colour, and nearly as 

 common as it is variable. 



Chorthippus elegans (Charp). "Bottisham Fen" (Jenyns); 

 also Whittlesea Mere and Wicken Fen. This species occurs 

 in a few scattered localities, but is usually numerous where it 

 does occur. Not uncommon at Wicken (Porritt). 



Ch. parallelus (Zett). Abundant throughout Britain. "On 

 rushes and fen-ditches," Thorney (Jenyns). 



Gomphocerus maculatus, Thunb. "Devil's Ditch and New- 

 market Heath, Gamlingay, Wilbraham Temple" (Jenyns). 



Family OEDIPODIDAE. 



Pachytylus danicus, Linn., a so-called Locusta migratoria, 

 is recorded from Duxford in September 1847, and also near 

 Wisbech and Fulbourn (Jenyns). It is probably referable to 

 this species. 



Family TETTIGIDAE. 



Tettix subulatus, L. " Coe Fen near Cambridge in April ; 

 not uncommon" (Jenyns).
