Madiza latipes, Meig. — The g'eniis Madiza is now placed in the Milic.hidse, 

 and I can confirm M. latipes as being British, for I have seen specimens in the 

 collections at Cambridge. I consider that the shape of the face and the long 

 pointed chitinous band down the middle of the frontal stripe, prove its correct 

 location in Madiza, instead of in Desniometopa, where it has been placed by 

 Becker. 



Cacoxenus. — This genus is placed by Becker among the Agromyzidse, but it 

 cannot possibly belong to that family. It seems to resemble in many ways the 

 genera at the commencement of the Drosophilidas such as Acletoxenus, Leuco- 

 phenga, and Phorfica, and may ultimately have to be located there, but at 

 present I leave it in the Milichidse where it has been placed by Loew, Schiner, 

 and others. 



*Rhicnoessa longirostris, Loew. — I am content with the identification of 

 this species as British, because my specimens agree with one iinder that name 

 in Kowarz's Collection, labelled " sec. typ. Loeivii." I have myself caught and 

 seen specimens from various sea-coast localities in Svxffolk, Essex, and 

 Dorsetshire. 



Bhicnoessa grisea, Fin.— This is the Anthomyza grisea of the old "List," 

 and is also a sea-coast insect. 



Tethina illota, Hal. — This species has not been corx'ectly recognised by 

 Kuntze and Strobl, for their specimens must be Rhicnoessa cinerella, Hal., or a 

 very closely allied species, and Haliday's description of illota -. " Fades impressa, 

 " epistoniate pi-o^ninulo nxulo. Peristoma elongatum. Labium cylindricum higeni- 

 " culatum " could not apply to cinerella. I am not certain that my own identi- 

 fication is correct, but specimens taken at PorthcaAvl (Glamorgan), in June 

 and Jvily, 1906, by Col. Yerbxiry, which would answer to the descriptions of 

 Rhicnoessa griseola, v. der Wulp = alhosetulosa, Strobl, represent my idea of 

 Tethi7ia illota. I refrain from substituting the name Tethina for Rhicnoessa 

 until such time as I can prove the correctness of my views. 



(To be co7icluded). 



NOTES ON THE OCCUEUENCE OF XEN0P8YLLA SCOPULIFER, 

 EoTHS., IN GERMAN EAST AFRICA. 



BY THE HON. N. CHARLES ROTHSCHILD, M.A., F.L.S. 



Messrs. Scliuberg and Manteufel recoi'd this species from Grerman 

 East Africa as liaviug been taken from rats.' This record has been 

 quoted by Messrs. Chick and Martin^ in their recently pubhshed 

 valuable paper. Through the kindness of the Director of the Kaiser- 

 liche Gesundheitsamt in Berlin, we have been able to examine these 

 specimens, which are Xeaoj^sylhi hrasiliensis, Baker, and not Xenop-
