Genus LIMATUS Theobald 

 LIMATUS DURHAMI Theobald 



This widely distributed little mosquito, which is easily recognized 

 by its brilliant golden and royal-blue thorax, was bred from larvae 

 found in rain-water collected in a fallen palm-leaf on the bank of the 

 upper Chagres River, where it was associated with Anopheles eiseni. 

 It was also bred from an old tin can, full of rain-water and rotten 

 leaves, in the woods near Tabernilla, and from a small wooden barrel 

 in a native village near Tabernilla. 



The larvae are ver\' long and slender and have a snaky movement ; 

 they are only found in water rich in decomposed vegetable matter.
