both sexes have been submitted to Brolemann, whose deter- 

 mination would therefore seem to be the more certain. As 

 matters at present stand, I feel bound to adopt the name 

 /. fallax for this Millipede. Very likely /. pilosus — which 

 is the older name — and I. fallax are synonymous, but a fresh 

 description of the former, from Newport's types, if they exist, 

 with special reference to the male characters, seems necessary 

 to settle the point. This (or the next) is probably the /. 

 terrestris of Leach (nec Linn.); and, according to Verhoeff, 

 /. longaho, Latz., is also to be referred to it. The confusion 

 thus indicated renders any useful statement on distribution 

 next to impossible. Eecords of /. terrestris in the Scottish 

 lists are valueless. /. pilosus has been recorded from England 

 and Ireland (9), and once from Scotland by myself (125). 

 /. fallax is recorded from south of England and Wales by 

 Sinclair (15). Abroad it has been recorded from Denmark, 

 Germany, etc., but not from Norway.

Widely distributed and by no means uncommon, this 

 species is very liable to be confused with the last. I am 

 indebted to Mr Brolemann, who uses the name /. ligulifer, 

 for the determination of a pair of my specimens. Adult $ $ 

 are abundantly distinct ; so much so that the two species 

 have been placed in separate sub-genera, Lejptoiuhts and 

 Micropodoiulus respectively, but $ $ and immature examples 

 are very much alike; with a little practice, however, they 

 can, I think, be separated — at any rate adult $ $ — with
