 Altlioiigh the difficulty of setting these tiny moths in the natural 

 position must be veiy great, I actually found three specimens in 

 which one or both wings had become engaged in the natural 

 manner; and one of these came from Mr, Meyrick's own col- 

 lection. 



Wishing to have my result tested in the field, I wrote at once 

 to Mr. A. Philpott, of Invercargill, X.Z., asking him to investi- 

 gate the coupling-apparatus in the wings of the living insect, and 

 sending him careful drawings of my results. The onlj^ species 

 that he was able to stud}^ was a new species of Sabatinca, of 

 which he reported that the coupling apparatus was exactly" the 

 same, in structure and position, as that of >S'. inconyrup/Ia, repre- 

 sented in m}" drawings. He also added some valuable notes on 

 the habits of flight and rest in this species.* 



We come, then, to the following conclusions with regard to the 

 Jlicroptpvi/g ida- : — 



(1) In so far as it is a fact, that a definite and well-developed 

 frenulum is present in this family, the}" are of a frpnate rather 

 than lijngafp type. 



(2) In so far as the so-called jugum does not pass backwards 

 under the hind wing, so as to engage the costa in a finger-and- 

 thumb grip, it is not a true jugum, but must be termed a juyal 

 lobe; also, for the same reason, these moths are not true jugate 

 types. 



(.H) Since the jugal lobe is turned forwards under the forewing, 

 and acts as a catch for the frenulum, it is clear that it should be 

 regarded as an archaic form of rptlnacidum, analogous to, but 

 not homologous with, the retinaculum found in the true Frenate 

 forms. 



(4) From this, it will be seen that the Microptpvygida- combine 

 in themselves certain characters belonging to both Jugate and 

 Frenate types.
