FAMiLL'E. {Jph. *^^. c. 3. a.) 161 



Leaves, has an entire anus, while that of the species, 

 which perforates the oak or ehn, is emargiiiate((f)* 

 Several are distinguished by the remarkable form 

 of the fore leg, especially the palm, which is dilated 

 and siagularly ciliated on one side (e) ; the males 

 that exhibit this peculiarity, have been all con- 

 founded under the name of j4. lagopoda. Thi^-; 

 conformation, however, of the fore leg is common 

 to several distinct species, which are separated froni 

 each other by very striking differences. The ge- 

 nuine u4. lagopoda of the Linnean cabinet is larger 

 than any other that I have seen, with filiform an- 

 tennas, and posterior tibiae very large and incras- 

 sate. A small one that stands by this, as a variety^ 

 in the same cabinet, seems distinct ; it is black, 

 less hairy, and its tibiae are proportion ably smalle]-, 

 it may be the Jf. lagopoda of Panzer (/). The 

 male of the willow bee, so well known to English 

 naturalists, which is the only male, of this descrip- 

 tion, that I have known taken in England, is dis- 

 tinguished from both these by its capitate antennae, 

 like those of a Papilio(g). The male of that species, 

 the centunculi of which so alarmed the poor gar- 

 dener and the priestj as described by Reaumur, has 

 the same kind of fore legs, and is also remarkable 

 for a quadridentate anus (A). This is the insect 

 referred to by Linneus as ^pis conica. The male
