This genus is readily distinguished by its long horns, from 

 whence its name Macrocera. Their metamorphoses have not 

 been discovered that I am aware of, but very probably they 

 are bred in Fungi. The following species have been found 

 in Britain. 



* AntenncB twice or thrice as long as the body in the males. 



1 . phalerata Hgg. 

 Ochreous spotted with black, wings with an abbreviated 

 fascia, a spot on the costa and the apex fuscous : 2^ lines 

 long. 

 Beginning and middle of June, Blarney and CoombeWood.
