The larvai of the four species described below were collected, with a 

 large number of others, from temporary pools which form on the plains 

 around this city after the seasonal rains. The different species were 

 separated into breeding bottles^ and specimens of the larval skin casts 

 and of the larvae themselves, when abundant, were preserved for study.
