The Cordylurae approach very near to Scatophaga, but the 

 proboscis and wings are shorter and the form of the abdomen 

 in the males very diiferent. Meigen has formed them into two 

 divisions : the typical species have the antennae, head, legs, &c., 

 very bristly, whilst those most remote from it are merely pu- 

 bescent; there are also great differences in the intermediate 

 species, C. spinimana has the anterior thighs and legs furnished 

 with long spines, somewhat like a Tachydromia (pi. 4<77. f. 8.), 

 others have the palpi dilated and varying in colour in the sexes 

 as in C. liydromyzina.

This pretty species, which is new to Britain, has been observed 

 on the leaves of the Water-lilies in the Stoure River, Hants, in 

 July for several years, by the Hon. C. A. Harris, who found the 

 greater number upon the yellow one (^Nuphar lutea, pi. 495). 



The Plant is Nymphaa alba {White Water-lily): the leaf 

 is represented about one fourth the usual size.
