No. 1599. SOME WESTERN ORTHOPTERA—CAUDELL. 75 
SPHARAGEMON COLLARE Scudder. 
Both sexes taken at Portal, North Dakota. 
SPHARAGEMON VENUSTA Stal. 
Both sexes taken on Santa Catalina Island, California. Also col- 
lected at Sisson and Thrall in California. 
LACTISTA GIBBOSUS Saussure. 
One female, Sierra Madre, California. 
TRACHYRHACHIS KIOWA Thomas. 
Common at Calgary, Moose Jaw, Canada, and Portal, North 
Dakota. 
CONOZOA BEHRENSI Saussure. 
Seven males, one female, Guadalupe, California, one female, San 
Diego, California. This species is very similar to swlcéfrons but the 
pronotum is decidedly more rugose above and the median carina 
more distinctly bilobate. The pronotum is also noticeably less elon- 
gate than in sulcifrons. 
CONOZOA SULCIFRONS Scudder. 
Both sexes taken at Indio, California. 
TRIMEROTROPIS ALBOLINEATA Bruner. 
Two males, San Diego, California. 
TRIMEROTROPIS CHRULEIPENNIS Bruner. 
Two males, Santa Catalina Island and Sisson, California. 
TRIMEROTROPIS CHRULEIPES Bruner. 
This species was taken at Thrall and Sisson in California and at 
Wellington and Nanaimo on Vancouver Island, British Columbia. 
At the latter place they were very active, making a loud crackling 
noise while in the air. 
This is a very variable species. The form with the apical half of 
the wing clouded was described by McNeill as ¢essel/ata from a single 
male specimen from Turkey Tanks, Arizona. I have a female from 
the same place taken on the same date, July 17, and it is unques- 
tionably this species and is topotypical. The name may be used in 
a varietal sense but the form is certainly not specifically distinct 
from the typical form with the wings apically hyaline. About 
seventy specimens are before me and the range of variation covers 
both forms. The variety has about as wide a range as the typical 
form, the above specimens from Vancouver Island belonging to it. 
TRIMEROTROPIS CITRINA Scudder. 
Taken at Calgary, Alberta, Canada. 
TRIMEROTROPIS KEOBELEI Bruner. 
One male, Dunsmuir, California. 
TRIMEROTROPIS MONTICOLA Saussure.
