The Mtcropterygidae Not of the Jugate Type (Lep.). 



By R. J. TILLYARD, Macleay Fellow in Zoology, Linnean 



Society of New South Wales. 



While carrying out researches upon the phylogeny of the 

 Panorpoid orders, I have made a careful study of the Jugate 

 Lepidoptera. The result of the study of five genera of the 

 family Micropterygidae (sens, lot., including the Eriocraniidae) 

 is that I find them all to be, not of the jugate type of the 

 Hepialidae, but of a more primitive jugo-frenate type, in which 

 the wing-coupling apparatus closely resembles that of the 

 Planipennia, Megaloptera and Alecoptera. On the hind wing, 

 near the base of the costa, there is a strongly developed frenu- 



lum of from two to six bristles (usu- 

 ally three or four), which becomes en- 

 gaged, during flight, in the sinus formed 

 between the dorsum of the forewing 

 and the so-called jugum ; this latter is

figure will explain these points clearly. I will shortly publish 

 a full account of my researches, and only send this short note 

 because of the present-day difficulties and delays in sending 

 communications from Australia to other parts of the world.
