France, North Africa, and Venice, but he distinguished L. xshmm ; 

 lastly, in 1909 Strobl placed L. vircjo from Spain and Dalmatia as a 

 synonym of L. maritima. I consider I am justified in naming two 

 females taken by Col. Yerbury at Walton-on-Naze on August 19th, 

 1907, and one female at Studland on Jul_y 29th, 1909, as L. maritima. 



76. Homalomyia fucivorax, Kieff. This recently distinguished 

 species (Ann. Soc. Ent. Fr. 1898) has been taken by Dr. J. H. Wood 

 in the Monnow Valley in Herefordshire. It is very much like the 

 common H. canicularis, but may be known by the wide silvery optics, 

 almost unstriped thorax, more extensively yellow knees, &c. Dr. Wood 

 tells nie that it appears to be associated with Odynerus spinipes ; if so, 

 the association of the genus Homalomyia with Aculeates is not new, 

 but the peculiar resemblance which the shape of the head and frons of 

 H. fucivorax bears to the species of Ammomyia must have some 

 significance. I suspect that Meade's H. vesparia is the same as Stein's 

 H. ciliata. 



77. H. lineata, Stein. A number of specimens were bred in 

 June, 1906, from rotten debris in a hollow tree at Snailwell, near here. 



78. Pegnmyia rtiji7ia, Fall. This species, of which P. squami/era 

 is probably a variety, has occurred at Dawlish. P. univittata,\. Eoser, 

 is probably a variety of P. genicuhita, Bouche, but I do not feel quite 

 certain upon this point. 



79. P. squamifera, Stein. This species occurred in considerable 

 numbers in my garden in June, 1904. 



80. P. interruptella , Zett. I caught a number of males of this 

 species hovering under a tree between Soham and Wicken on May 

 15th, 1892. I had previously taken one male at Lyndhurst on 

 June 10th, 1884. My specimens were named by Stein, and therefore 

 probably represent this little known species. 



80a. Pegomyia femorata, Stein. This may not be an addition to 

 the British List, because Stein says that it is Meade's P. hsemorrhomn. 

 I must admit that I ain not satisfied with Stain's distinctive charac- 

 ters for this somewhat common species. 



81. Antliomyia yrocellaris, Eond. I think A. phivialis was 

 rightly separated by Rondani into three species, as I find genital 

 characters supporting his superficial characters. It is however probable 

 in that case that there ai*e several more South European species, 

 aud therefore the nomenclature must for a while remain uncertain. 

 A. procellaris is widely distributed in Britain,
