find nothing by which to separate the two species. The marsupium in the 

 type 5 was practically destroyed, so that it was not possible to check 

 Douglas's remarks regarding it, but in the meantime I think we are justified 

 in regarding O. maenarieyisis as a synonym of O. tiHicae L. and sinking 

 MacGillivray's Douglariella to Orthezia Bosc. — F. Laing, British Museum

Aleyrodidae : correction of generic nomenclature. — Messrs. Quaintance and 

 Baker in their "Classification of the Aleyrodidae," Part ii (U.S. Dept. Agr., 

 ]Jur. Ent., Techn. Ser. 27, pt. ii, 1914), assigned Aleurodes vaporariorum 

 Westw., as the type species of Asterochiton Mask., while they erected the 

 genus Dialeitrodoides with Aleurodes attreus Mask, as the type. In the " Con- 

 tents and Index " to the Classification, published in 1915, the authors, in the 

 corrigenda, p. xi, point out that Cockerell had in 1902 designated aureus 

 Mask, as the type of Asterochiton Mask., and cited penjandei Quaint, as the 

 type of his sub-genus Trialeurodet>. A. pergandei is congeneric with vapor- 

 ariorum Westw. The synonym stands, therefore, as follows : — 



Asterochiton (Mask.) Ckll., type aureus Mask. 



DiALEUKODOiDES Quaint. & Baker, type aureus Mask. 

 Trialeurodes Ckll., type perga7idei Quaint. 



Asterochiton Quaint. & Baker, type vaporariorum Westw. 



I bad not seen the " Contents and Index" section (we do not seem to have 

 a copy in the library here, and there is no mention of it in the "Zoological 

 Record"), and it was not until Dr. A. S. Neave showed it to me that I was 

 aware of its existence. As I have followed Quaintance & Baker's nomencla- 

 ture and spread the mistake, I take this opportunity of pointing out to English 

 Entomologists the necessary change. — F. Laing, British Museum (Natural 

 History) : October IQth, 1922. 



Localities for Kotonecta halophila J. Edxo. — During the last few weeks 

 Miss J. Barrington and Mr. J. Omer Cooper have kindly Bent me several 

 specimens of this species. Miss Barringtou's specimens are fruui three 

 localities near Bridgwater, Somerset, all at some distance from tlie sea. 

 Mr. Omer Cooper's are from Little Sea, Studland, Dorset, and New Milton, 

 Hants. I believe other collectors have taken the species in the latter county 

 frequently. I have also one specimen taken at Madingley, near Cambridge, in 

 a pond where N. ylauca is common. — G. E. Hutchinson, Aysthorpe, Newton 

 lload, Cambridge : October 10th, 1922. 



Billaea irrorata Alg. in Britain. — In Major Austen's interesting note upon 

 new British Tachinidae in pp. 182 and 188 of the present volume of this 

 Magazine is a record of the occurrence of this species in various localities 

 in this country in the years 1921 and 1922. I took a single female on 

 August 19th, 1898. It was not identified by me until 1909, since when, 

 however, it has been in my collection over its correct name. It was taken iu 

 Kan Dan Woods, in Worcestershije. — Colbhan J. Wainwright, Daylesford,
