34 B. C. ENTOMOLOGICAL SOCIETY 



Cyphoderris monstrosus Uhler. Syhaii. A nocturnal species. 



May be found during the day time beneath logs and flat stones in the 



forests. 



Family GRYLLIDAE 



Gryllus abbreviatus Serville. A saxicolons campcstrian. An un- 

 common insect in this locality found only in warm situations close to 

 the Fraser River. Frequents rock-slides and stony ravines, where the 

 males may be heard stridulating during the heat of the day. 



Oecanthus quadripunctatus Beut. A phytophiloits campcstrian. Found 

 occasionally among tall plants and rose bushes in dry, warm ravines in 



the river valleys. 



Family ACRIDIDAE 

 Tettiginae 

 Acrydium granulatum Kirby. A huinicolous hygrophile. Taken only 

 in damp grass beneath willow and birch close to water. Both long and 

 short-pronotumed forms were collected. 



Acrydium brunneri Bol. A Jiimiicoloits hygrophik. Observed only 

 in one small area among fallen leaves and moss under birch and willow 



around an upland spring. 



Tryxalinae 



Amphitornus bicolor McNeill. A pJiytophilous campcstrian. Inhabits 

 the bunch-grass slopes of the river valleys. A few found on Upper table- 

 land in depressions where the herbage was fairly plentiful. 



Chloealtis abdominalis Thomas. Syhan. Very common. Fre- 

 quenting open forests, especially where logging operations have been 

 conducted leaving the ground strewn with dead limbs. Less plentiful 

 in aspen groves in semi-sylvan locations. 



Chloealtis conspersa Harris. Syhan. Common. Inhabiting open 

 forests in company with C. abdominalis. 



Mecostethus gracilis Scudder. A palndicolous hygrophile. Collected 

 in wet marshes and flooded areas in wild hay mea'dows. Flies actively 

 about in the tops of tall grasses and rushes. 



Chorthippus curtipennis Harris. A humicolous hygrophile. A very 

 common species in long rank meadow grass and under aspens in damp 

 locations. Extending in places into distinctly sylvan surroundings. 



Platybothrus brunneus Thomas. A geophilous campestrian. Was 

 found in great numbers over approximately 1,000 square miles of dry, 

 bare, overgrazed range. The only geophilons species of this sub-family 

 collected and, I believe, the first record of a Tryxaline occurring in 

 injurious nuinbers in Canada. 



Oedipodinae 



Arphia pseudonietana Thomas. A phytophilous campestrian. Rarely 

 seen. Taken in small numbers in hot, dry ravines, and among sage 

 brush near the Fraser River. 



Camnula pellucida Scudder. A geophilons campcstrian. This common 

 and destructive species was found everywhere on the open range land.
