1902.] 109 



6. — C. guttatus, Curt., has long been accepted as a synonym of C. nemorosus, 

 Meig. 



7. — Cecidomyia pictipennis, Meig., remains where it was in my List of 1888. 

 Walker did not include it as British in 1856. 



8. — It is, according to MS. notes of mine, and I expect that is the reason that 

 I included L. rubi, Schrk., in my List of 1888. 



9. — It is possible ; but C. dolens, Wlk., is apparently an Orthocladius, while 

 Zetterstedt's name would sink as a synonym, on the ground of priority, if the two 

 should prove to be the same species. I possess a distinct Chironomus, which I have 

 been calling C. anthracinus, Zett. 



10. — Chironomus tarsa/is, Wlk , and C. modicellus, Wlk., are in the expurgated 

 List as being merely encumbrances. They have never yet been " described," and 

 therefore it is impossible to say of what species they are synonyms. 



11. — Ceratopogon is a most remarkably homogeneous genus, and all attempts 

 to divide it have been failures. When Winnertz monographed the Mgcetop/iilidee, 

 he made scores of new genera, but in his exquisite monograph of Ceratopogon he 

 recognised that he was dealing with a large natural genus. Some recent further 

 attempts by an inexperienced French author would place numerous males in one of 

 his so-called genera, and the females in another genus. If Mr. Dale will give us 

 thoroughly reliable characters (distinguishing, without doubt, in all species) of 

 Sphreromyia, Culicoides, Serromgia, and Forcipomgia, he will grant a great boon to 

 Dipterologists, because for some seventy years we have been searching for those 

 clear distinctions. 



12. — Nothing to do with my " List." 



13. — Xiphura rujicornit, Meig., was more than fifty years ago accepted as a 

 synonym of the very variable X. atrata, L. 



14. — As Mr. Dale says "at present the question is not quite cleared up." I 

 consider the distinctive characters of the European species of Orimarga still very 

 uncertain. 



15. — Xgsta cana, Meig., v. Phasia Rothi, Zett. ; see Austen, Ent. Mo. Mag., 

 xxxiv, 39. 



16. — If Moses Harris had described a Mitsca permundus I would have 

 accepted his name, but unfortunately he did not do so. The name he gave is 

 inadmissible, as it is not Latin. 



17. — Nothing to do with my " List." 



18. — I suppose Masieera virilis, Rnd., was omitted because I had not the 

 vaguest idea what species was intended. When Meade could return Sarcophaga 

 carnaria to an enquirer as a fine new species of Masieera (as I am assured he did) 

 I do not think that he understood the limits of the genus.' 



19. — See British Flies (Sgrphidte) pp. 589 and 633. I only re-instate Moses 

 Harris' names when they are indisputable ; in this case there is doubt which can 

 never be cleared up. 



20. —Baron Osten Sacken has himself said that lie does not expect his proposed 

 changes to be adopted without long consideration, and possibly modification after 

 they have been well tested. I desired to make as little change as possible from my 

 "List" of 1888, though I can foresee many changes probable, but I hope gradual, 

 such as (pace Osten Sacken) Rhyphus and Leptis next to each other.
