226 [October, 



It ahould be observed that No. 4537 of Stgr. & Ebl., Cat., ii, 

 p. 236 (1901), embraces three distinct species, viz., Monopls rnxtlcetla, 

 Hb., M. weavereUa, Scott (=: semispUotella, Strand), and BlaJxqjhaues 

 spilotella, Tgstr., and that, in consequence, the synonymy there given 

 requires careful correction. 



Although Norway is the only continental habitat of M. iveaverella 

 at present ]\:nown to me, the species shows a remarkably wide distribu- 

 tion in Britain, and I have been able, partly through the kindness of 

 friends, to examine and identify individuals fl-om the following locali- 

 ties therein : ENGrLAND — Dorset (Bloxworth, one, E. B. Bankes) : 

 Hampshire (Brockenhurst, one, E. B. Bankes ; Lyndhurst, one, E. B. 

 Banlces) : Herefordshire (Tarrington, not imcommon, /. H. Wood) : 

 Sussex (Abbots Wood, not imcoiuinon, A. F. Grifith, T. SaJvaye, 

 A. C. Vine; Hassocks, taken sparingly, A. C. Vine). SCOTLAND— 

 Aberdeensliire (Braeinar, apparently not uncommon, P. M. Bright) : 

 Inverness-shire (Aviemore, widely distributed, but rather sparingly 

 taken, C. T. Crtithoell, E. B. Bankes) : Perthshire (Mas. Bankes) : 

 Sutherlandshire (Strath Naver, two, A. F. Griffith). 



Except for Weaver's " Perthshire " (captures, recorded by Staiuton 

 [Ins. Brit., Lep. Tin., p. 27 (1854)] as perhaps representing a variety 

 of M. rusticella, the only British examples of weavereUa known to me, 

 that I have not actually seen, are the original co-types taken by Scott 

 at Raunoch. Perthshire, where he found it not uncommon ; his notes 

 (I.e.), however, leave one in no doubt whatever as to the insect that 

 was before him. C. G. Barrett's series of rusticella, which I acquired 

 at the dispersal of his collection, included a few examples of weaver- 

 eUa: one of these bears his written label "Perthshire," while the 

 rest, which were, to my knowledge, taken and set by Dr. J. H. 

 Wood, are labelled, in Barrett's handwriting, either " Ledbu2-y," or 

 " Tarrington in woods," both names denoting the Tarrington district. 



Since the above notes were written. Dr. T. A. Chapman has, at 

 my request, Icindly compared the genitalia of M. rusticella and 

 weavereUa, and his valuable preparations fonned the subjects of the 

 photographs, which are reproduced on the accompanying plate. He 

 informs me that the appendages of these species " are close, but 

 sufficiently distinct to confirm specific non-identity deduced on other 

 grounds," and I am greatly indebted to him for the following detailed 

 notes respecting them.
