334 THE BLOWFLIES OF NortH AMERICA 
Cynomyopsis, but fly in straight courses like species of Oestridae 
or Sarcophagidae. Adults may be seen about swampy areas par- 
ticularly in the vicinity of gopher holes. Both sexes may be in- 
frequently collected upon swampy ground as they come in for 
water or they may be collected still less frequently as they dart 
into gopher burrows or as they rest in the shade of dense sage- 
brush thickets. Two male specimens were collected by my son 
upon regurgitated dog food, but this is the only instance known 
to me of specimens attracted to any attrahent. As many as five 
collectors made numerous collecting trips to areas where the 
species was known to be present, but approximately 20 specimens. 
comprised the total collection of nearly 5 weeks’ effort. 
Adult females deposited eggs upon decaying meat in rearing 
cages. One female collected on July 30, 1940, at 8500 feet eleva- 
tion, along a seepage area.on Beaver Creek in Upper Logan 
Canyon, Utah, deposited 76 eggs in batches of 6 to 10 eggs each. 
Another female collected in the same area remained alive for 
38 days in a small cage and probably would have lived con- 
siderably longer had not an attempt been made to transport it 
to the east. 
As indicated by Hough in the original description of elongata, 
one male and one female of this species were collected in copula.. 
These specimens are in the National Collection. In the type 
series were two other specimens, a male (Lectotype) from Tor- 
rey’s Lake, Wyo., and a female from Brookings, S. Dak. The 
latter two specimens are in the Field Museum, Chicago, the male 
marked ‘‘Type.’’. All were originally treated as cotypes.
