 [Verrall]. 

 NB. „In conflict with another turpis Wk., Ins. Saund. 

 Jan. 1856; under the donbt and carelessness I think 

 both Walker's names had better cease." Verrall, 

 1. c. p. 158. 

 (?) Dicranomyia ptibipennis O.S., Proc. Ac. Nat. Sc. Phil., 

 p. 211 (1859); Monograph's etc. IV, p. 73, Tab. I, f. 2 

 [Verrall; O.SJ. 

 NB. This American species is, according to both anthors, 

 very probably the same as the European pilipennis 

 but its priority should not be accepted for the Euro- 

 pean species without further verification. 



3. Trochobola annulata Lin. 



When I discovered this species near S. Petersburg I rccognized 

 at once tliat it was something new, but, with the reserve of a beginner, 

 I sent it to Loew to describe. I was soon rewarded for ray courtesy 

 by the fact that I had to correct Loew, and not myself, when I 

 asoertained in Linne's collection in London that it was the Tipida 

 annulata Lin. and not a new species. (Comp, my article in the 

 Stett. Ent. Zeit. 1857, p. 90—91.) 



Prof. Mik has published an elaborate and very interesting paper 

 in theVerh. Z. B. Ges. 1878, p. 617— 632, entitled: Ueber die Art- 

 rechte von Trochobola caesarea O.S. ') This article contains 

 a critical history of the career of Tipida annulata Lin. in the 

 dipterological literature, as well as a vindication of Limnobia cae- 

 sarea 0. S. as a different species. I have carefully compared this 

 paper with the original publications, and can bear witness of its com- 

 pleteness and cxactitude. A few additional remarks may not be 

 amiss here: 



1. Linne's X th edit, 1758, p. 586 (which Mik did not have at 

 hand) contains the same short diagnosis as the XII th edit., reproduced 

 by Mik, 1. c. p. 620. It is followed by the mention: Fn. Süec. 1122, 

 the (wrong) quotation from Reaumur, and the: Habitat in Europa. 



2. The T. annulata Scopoli, wrongly quoted by Linne X th edit. 

 p. 973, 16, and many times wrongly referred to by Fabricius, is 

 very probably Poecilostola pictipennis M., the slight discrepancies 



i) In the Wien. Ent. Zeit. 1884, p. 65— 67 Mik has published a 

 careful description of the pupa of T. caesarea (both <f and $) with 

 figures.
