The object of this short paper is to call attention to a fact 

 in the anatomy of the species of the genus Micropteryx* 

 that appears so far to have escaped observation — at any 

 rate, I am not aware of any record of it — and which is yet 

 one of primary importance, with reference to the position 

 of the genus in any classification. 



It might give this paper a more imposing length if I 

 fully quoted Walter's f account of the mouth parts of 

 Micropteryx, and my own paper on the larva, J and espe- 

 cially to transfer in full Packard's discussion § of these 

 papers, in which he founded for Micropteryx a sub-order 

 Proto-Lepidoptera, or Lepidoptera laciniata, a dis- 

 cussion occupying three and a half pages of his Monograph 

 on the Bombycine Moths. Packard notes a further charac- 

 ter, viz. " the male genital armature neuropteroid, exserted, 

 dorsal, lateral, and sternal appendages very large." 



These papers are, however, fairly accessible, and under 

 present conditions it seems a duty to make a paper as 

 short, instead of as long, as possible. 



Packard would have been justified, on the facts before 

 him, in placing Micropteryx in a new order, instead of a 

 sub-order. However this may be, the further structural 



* Micropteryx, Hubner, seems to be the name to which this 

 genus is entitled. In my paper on the larva I adopted the name 

 Eriocephala, and Packard did so also. This is a name given by 

 Curtis, and sinks as a synonym; but it had (and has) the advan- 

 tage of referring to this genus only, whereas Micropteryx for long 

 included Eriocrania also, and has even been applied, but of course 

 wrongly, to Eriocrania, to the exclusion of Micropteryx proper 

 (calthella, F.).
