RETROSPECT OF A DIPTERIST FOR I'.IOl. 55 



Retrospect of a Dipterist for 1904. 



By JAS. E. COLLIN, F.E.S. 



The most noteworthy addition to the recorded species of British 

 diptera during the past year is that of L'allkera yerbun/i, Verr., a 

 species new to science found by Col. Yerbury at Nethy Bridge in 

 Invernessshire, the discovery of such a large and handsome Syrphid 

 is the more remarkable when it is considered that the Sijrjihidac, by 

 reason of their size and showy appearance, have been more widely 

 collected, and are consequently better known, than any other family of 

 the diptera. Mr. C. G. Lamb is responsible for another addition of 

 special interest, c/c, that of <khthera iiicaitispa, Lw., a Mediterranean 

 Ephydrid taken near Padstow, and he also records the capture of 

 Peri.'<ci'lis anniilata, Fin., in the New Forest and at Cambi'idge {K)it. 

 Mo. Mag.). 



Mr. Verrall has published a " List of the British Dulichopodidar" 

 {Ent. Mo. Ma;/.) adding one genus and seven species to the old list, 

 r/c, ('hryaotiis )iwnocIiaetus, Kow., DoUchopna andalusiacus, Strobl. 

 (previously standing in our list under the MS. name of D. scottii), D. 

 laticola, Yerr., new to science ; fJydrophoras niribarbiH, Gerst., only 

 previously known from one male taken near Stettin, and one female 

 taken near Berlin ; Porpluirops patida, Radd., Sij)iipijciius spiculatus, 

 Gerst., and Si/atciuis adjjiopiwjuaiis, Lw. The Rev. E. N. Bloomfield 

 has recorded ('Iiyliza rittata, Mg., ] >iloplnis teniatiis, Lw., and Tanypiza 

 lonyiiiHina, Fin., as occurring in this country, and Mr. F. Jenkinson 

 the capture of the third known species of Asteia, vis., A. elet/antida, 

 Ztt. {Knt. Mn. Mail.). 



The Rev. A. E. Eaton, in commencing a " Revision of the genera of 

 the Psychodidae" {Ent. Mo. May.), has indicated five genera and two 

 species new to science and Britain. The present writer has contributed 

 (Ent. Mo. May.) a "Revised list of the British Cecidoinyidac," adding 

 fifteen new specific names, and bringing their arrangement in line with 

 that of European lists, and, at a meeting of the Entomological Society 

 of London, on May -ith, exhibited specimens of Corethra obscurijies, 

 V. d. Wulp, a Calicid new to Britain, while at the same meeting Mr. 

 Verrall exhibited specimens of Xeoitaniiis fot/inrnatiis, Mg., an addi- 

 tion to the ]iritish A^iilidar taken near Oxford. 



Mr. P. H. Grimshaw has recorded Sriara nifivcntris, Mcq., from 

 Saline, Fife ; Oncomyia aundewalli, Ztt., from near Oban, and 

 Hydmtaea pilipes. Stein, from Aberfoyle (^/(». Scot. Nat. Hist.); while 

 Mr. Evans published the capture of a specimen of Sajmniiyza a/iiniK, 

 Ztt., from Newpark, Midlothian (Ann. Scot. Xat. Hint.). 



On the Continent, Becker's " Monograph of the Pahearctic species of 

 Liapa'' {Zcitacltr. /. Ent.) and Czerny's " Monograph of the Helo- 

 myzidae'' {Wien. Ent. Zcit.), probably form the two most important 

 descriptive works. In addition, Czerny has published papers on the 

 genus Ayat/iiiiiiyia and on the Oc/it/iiphilinac {U'icn. Ent. Xeit.), and 

 Becker an article on the genus I'chtliop/tila {Zcitschr. Jlym. ii. Dipt.), 

 which latter genus has also been dealt with by Bezzi {Att. Soc. Ital. 

 Sc. Xat.). 



AVahlgrcn has given some interesting notes upon the types of 

 Zetterstedt's Xonoccra {Arla'r f. Ztxd.). Yilleneuve contributes 

 towards a *' Catalogue of the Diptera of France " {La EcuilU). An 

 March Ioth, 1905.
