REPORT OF ENTOMOLOGIST. 
AULOCARA Sou elder 
elliotti Thom. This is also a very abundant species over the grass- 
covered plains of the eastern portion of the State, and 
occurs upon open grassy areas in the mountains to an altitude 
of 8000 feet. Adults appear in the vicinity of Ft. Collins 
about the middle of June and the sexes have been taken in 
coitn as early as July 2. 
The 75 females in the collection vary in length between 
21 mm. and 27 111111. and their elytra between 16 111111. and 
18 mm. The males vary between 17 111111. and 20 111111. and their 
elytra between 11 nun. and 1 7 111111. 
There is a wide variation in the colors. The common 
one is a dingy brown, slightly tinged with rufous, with more or 
less numerous brown spots, particularly upon the elytra. Occas¬ 
ional specimens are deep ferruginous in color with or without 
. the fuscous spots upon the elytra and with the posterior portion 
of the dorsum of the pronotum deeply infuscated. Specimens 
from the higher altitudes (Buena Vista, Antonito and Gunni¬ 
son) are smaller and are of a dark slate color with markings 
very inconspicuous. 
Our specimens came from the following places: Ft. Collins, 
Laporte, Pike’s Peak at 9000 feet (Cockerell), Dutch George’s, 
Livermore, Sterling, Boulder, Lafayette, Ya. Dale, Nepesta, 
Rockyford, Lamar, Trinidad, Canon City, Buena Vista, Anton¬ 
ito, Durango and Dunkley. 
femoratum Scudd. A very abundant species near the foothills in 
northern Colorado. It occurs among the native grasses which 
probably serve as its food plants. It occurs entirely across the 
plains to the eastward but we have not found it occuring far 
back in the foothills nor upon the western slope. O11 July 16, 
1902, adults were just beginning to appear in the foothills west 
of Fort Collins (Ball). In 1901 a few males were found in‘the 
same locality June 29, and on July 26th of this year Mr. Ball 
found females containing fully developed eggs. Occasional 
specimens have been observed at Fort Collins as late as Sept. 
30, (1902). 
This species has been collected at Ft. Collins, Laporte, 
Dutch George’s, Windsor, Greeley, Ft. Morgan, Boulder, 
Rockyford, Las Animas, Lamar and Holly. 
An examination of the 74 females and 52 males in the col¬ 
lection shows that the former vary between 19 and 25 mm. and 
their elytra between 12 mm. and 19 mm. in length, and that the 
latter vary between 14 mm. and 17 mm. and their elytra between
