time was almost dry, to sweep tlie yellow Asphodel {Nartheciiim ossifriri/um) for 

 Paracrocera '/fobiihis. Pz., but without any tsuccess, and the heat being excessive I 

 gave up further attempts. I was absent from the Forest during August, but 

 September was a fine dry month, and a noticeable feature was the re-appearance in 

 some numbers of Melanostoma ht/alinatuin* Fin., after being scarce since 1895. The 

 result was twenty specimens, almost equally divided S ^''"'-1 ? , and I also took 

 sixteen more of what was apparently a second brood of D. fasciata, Mcq. 



Throughout the season I noticed more MycetophilidcB and other fungus-loving 

 Diptera than usual, and amongst the former I took the following, of which, how- 

 ever, in some cases I only give the generic names, being doubtful about my nomen- 

 clature of the species being correct : Mycetophila, two, and Qlaphi/roptera, Scio- 

 phila, Maerocera, five species of each genus ; also two Leptomorplius Walkerii, Curt., 

 a rare fly I have not seen since 1895 ; one Platyura atrata, F. ; two P. fasciata, 

 Latr., and seven Ceroplatus sesioides, Whlb. 



Amongst the other flies referred to were ten Spilogaster idiginosa. Fin., and two 

 Myeophaga fungorum,& species I have only taken once before in 1S92. 8. uliginosa 

 turned up singly in 1895, 1897, and 1899, and once when sending a specimen for 

 confirmation to the late Dr. Meade I remarked that althougli he called it common 

 in his " Annotated List of Anthomyidse," I had not found it so at Lyndhurst, and 

 in reply he wrote as follows : " >S. uliginosa is very variable and lofal, and I cannot 

 think what the larvse feed upon. I used to live in a house quite in the centre of 

 the town, and then found a considerable number of specimens (always) upon the 

 windows. I have been sixteen years in my present house just outside the town, and 

 have never seen a single specimen." My specimens also were taken upon windows, 

 and although I have not yet proved the fact by breeding the larvae, I have very little 

 doubt about their pabulum being rotten timber and the fungi associated with the 

 same, as the basement of my cottage is badly afl^ected with what is called " dry rot." 

 I also believe it is from the same source I obtain C. sesioides, as they are also 

 found on the windows and walls of the same rooms, and have given instructions 

 that next time any repairs are made the rotten wood is to be saved, and by placing 

 some blocks of it in breeding cages hope to solve this question. 



In addition to those already mentioned the following species were taken : one 

 Ptychoptera lacustris, Mg. ; four Rhipidia maculaia, Mg. ; one Idioptera pulchella, 

 Mg. ; one Dysmaclius trigonus, Mg. ; two Volucella inanis, L. ; one Prosena 

 siberita, F. ; one Lispe tentaculata, Deg. ; four Norellia spinimana, Fin. ; Amauro- 

 soma fasciata, Mg. (com.); one Tetanocera punctata, F. ; one Liinyiia iiiarginata, 

 F. ; one Dorycera graminiim, F. ; JEnsina sonchi, L., and Tephrites vespertina, Lw. 

 (both com.); three Sapromyza fasciata, Fin.; one Oni.ithomyia avicularia, L., 

 and others. — Fred. C. Adams, 50, Ashley Gardens, S.W. : January, 1901. 



Two unrecorded British Diptera. — I have specimens of a fly which both my 

 father and myself considered to be the Musca erythrophthal ina figured by Panzer. 

 Mr. Austin, who has seen it, tells me it is Chlorops rufina, Zett. ; they frequent the 

 flowers of Mentha hirsuta in the month of August. The other species is Phytomyza 



* Since writing the above I have olitained a copy of Mr. Verrall's new work, " Briti.sh 

 Flies (Syrpbidai)," and find M. hvu.<i'iiuliuii. Kin., must in future be known as Xanlliandrus comtug
