cinerea Brim. What I have placed under this name seems to be a 
light colored form of occipitalis , and it occurs over about the 
same area. Perhaps my specimens are not true cinerea , but 
if so, we have not taken this species in the State. 
crenulata Brun. Generally distributed on dry grassy areas east of 
the Continental Divide to 8,000 feet altitude and also occur¬ 
ring over some of the western slope. It seems to be a grass 
feeder. The earliest that adults have been seen at Ft. Collins 
is June 26, 1901. (Ball.) They continue until the middle of 
September. 
Specimens taken at FT Collins, Laporte,Windsor,Greeley, 
LaSalle, Wray, Boulder, Denver, LaFayette, Colorado 
Springs, Pueblo, Rockyford, Lajuhta, Lamar, Las Aninas, 
Trinidad, Ridgway, Antoni to, Durango and Grand Junction. 
occipitalis Thom. The notes for the preceding species may be re" 
peated for this. In addition to the above localities we can 
add Dolores, Salida, Golden,Virginia Dale, Timnath, Ft. Mor¬ 
gan, Julesburg, Merino, Trinidad, Alamosa, Antonito and 
Durango. 
Specimens from Tiinidad, Alamosa, Antonito and Du¬ 
rango are darker in color and the elytra are longitudinally 
striped with dark fuscous with or without light yellow spots, 
but I do not take this form to be specifically distinct from the 
specimens from other parts of the State as there is considera¬ 
ble inter-gradation. 
PHLIBOSTROMA Scudder. 
quadrimaculatum Thom. very common species feeding upon prairie 
grasses, particularly on the plains of the northeastern portion 
of Colorado. The species occurs in the foothills at an altitude 
of about 8,000 feet. It varies much in size and color, and in 
wing-length. This is one of our most destructive species to 
prairie grasses. 
Specimens taken at Ft. Collins, Laporte, Dutch George’s, 
Virginia Dale, Livermore, Windsor, Greeley, La Salle, Sny¬
