THE MUSEUM. 



by such means failures were the rule 

 and captures the exception. Hundreds 

 of these were seen in various pools 

 where the water was too hot for the 

 insects. In some cases they were 

 cooked, and were so soft and unsightly 

 as to be useless as specimens. At first 

 it would appear difficult to account for 

 their presence in these hot pools. 

 From the fact that many males are 

 among the dead it cannot be from an 

 attempt at depositing eggs in water 

 too hot to endure. They undoubtedly 

 are overcome by the escaping steam, 

 smothered and boiled. Siviplicieollis 

 has an extensive distribution, being 

 found in the United States generally 

 west of the Rocky Mountains, in Mex- 

 ico, West Indies and the Bahamas. 

 The variety collocata is found in Tex- 

 as, Yellowstone National Park, Cali- 

 fornia, and Baja, California. Calvert 

 is of the opinion that the varietal dif- 

 ferences are very slight and it is doubt- 

 ful if the variety should be considered.

The dragon flies of the Park are not 

 very numerous in species, but are very 

 interesting, and are deserving of more 

 extensive study.
