EXPLANATION OF PLATES XXLX.-XXX. 



Plate xxix. 



Fig. 1, — Jugum of MicropUryx aruucel/a Scopoli, viewed from beneath ; 



( X 150). 

 Fig. 2. — Frenulum of same, viewed from beneath; ( x 125). 

 Fig. 3. — Humeral lobe and bases of insertion of frenular bristles in Saba- 



tinea inconr/ruel/a (Walker); ( x 250). 

 Fig. 4. — Frenulum of Micropteryx thunhergeUa Fabr. ; ( x 125). 



(Photomicrographs from descaled, cleared and mounted specimens. 

 The jugal lobe in Fig.l, and the humeral lobes in Figs. 2 and 4, have 

 become cracked across near their bases, owing to the pressure of the cover- 

 glass upon old and brittle material. Owing to the same cause, the frenular 

 bristles have become pressed down upon the hindwing, and their correct 

 directions somewhat altered). 



Plate XXX. 

 Fig. 5. — Jugum of Charagia eximia Scott, viewed from beneath; ( x 8). 

 Fig.6. — Frenulum and retinaculum of Cephenodef^ janus janu.^ Miskin, 9 , 



viewed from beneath; ( x 5). 

 Fig. 7. — Frenulum and retinaculum of Hippotion scrofa Boisd., 9 , viewed 



from beneath; ( x 7). 

 Fig. 8. —Frenulum and retinaculum of Hippotion scrofa Boisd., <J , viewed 



from beneath; ( x 6). 

 (Photomicrographs from set specimens, not descaled. In Fig. 7, the 

 black bristles of the frenulum appear white, owing to the incidence of 

 strong artificial light directly upon them).
