A Further Note on the Wing-Coupling Apparatus in the Family 

 Micropterygidae. (Lep.). 

 The short note made by the author on this subject in Ent. News, 

 Vol. xxix, p. 90 (March, 1918), needs correction in an important par- 

 ticular. The study was carried out on the five genera Micropteryx, 

 Sabatinca, Mnesarchaea, Eriocrania and Mnemonica. Of the first 

 three genera plenty of good material was available, and the results 

 obtained were undoubtedly correct. Of the other two, the author had 

 unfortunately only one or two very poor specimens. Further work on 

 better specimens since received has demonstrated clearly that these 

 two genera, belonging to the subfamily Eriocraniinae, though they 

 possess a frenulum as before stated, do not have the jugal lobe turned 

 under the forewing; this lobe projects backwards above the costa of 

 the hindwing, as Comstock has recently figured it. Thus there is a 

 very distinct difference between the condition of the jugal lobe in the 

 Micropteryginae and Mnesarchaeinac on the one hand, and that of the 

 Eriocraniinae on the other. Considering also the differences in larval 

 structure, it seems clear that we are really dealing with three distinct 

 families, and that Meyrick's uniting of them all into one can only 

 result in much confusion of ideas. — R. J. Tillyard, Hornsby, New
