﻿CRITICAL NOTES ON DIPTERA. 153 



taken by Van der Wulp, and I possess six males of a closely- 

 allied species, seven males of another which would pass under 

 Stagger's description, one male of a fourth species, and two large 

 males of a fifth species with dark tibise, besides females of 

 several species. Who can say which of my five species is 

 Chironomus nigrimanus, Stseg., and what species were repre- 

 sented in the stragglers previously recorded ? 



Limnobia stigma, Mg. ; common in North Wales. 



Dicranomyia omata, Mg. ; in Eev. T. A. Marshall's collection. 



Atherix unicolor, Curt. = Ptiolina wodzickii, Frfld. I will not 

 at present discuss the priority of name. 



Rhamphomyia dispar, Curt. = Ocydromia glabricida, Fin. ! 



(Edalea stigmatica is a misprint for stigmatella. 



Clinocera barbatula. Instead of " Hal." put " Mik." 



Tachydromia stramineipes, Zett., is only a variety of T. 

 pectoralis, Fin. I caught a long series last August in Tilgate 

 Forest showing every gradation. 



Psilopus obscurus, Mg., is probably a synonym of P. longulus, 

 Fin. 



Neurigona pallida, Fin. ; confirmed. N. suturalis, Fin. ; con- 

 firmed. N. Erichsonii, Zett. ; relegated to " Reputed Species." 



Gymnopternus pa/rvilamellatus, Mcq., is a Hercostomus. 



Chrysotus angulicornis, Kow. 



Argyra atriceps, Lw. 



Sympycnus nig ritib talis, Zett. = S. ceneicoxa, Mg. S. bifasci- 

 ellus, Zett. = Lamprochromus elegans, Mg. 



Platypeza modesta, Zett., and P. rufa, Mg. Quite correctly in- 

 troduced in Mr. C. W. Dale's 'History of Glanvilles Wootton.' 



Chalarus holosericeus, Mg., is only the other sex of C. spurius, 

 Fin. 



Pipizella biguttata, Curt. = P.flavitarsis, Mg. 



Chilosia mutabilis, Fin. ; confirmed. 



Rhingia campestris, Mg. I am now convinced that there are 

 more than one species of Rhingia in Europe, and that our common 

 species is li. campestris, Mg. I am not yet satisfied that 11. 

 rostrata, L., also occurs here, although I expect it does. 



Anthomvidte. The four subfamilies I have indicated are 

 distinguished as follows : — 



MydjeiNjE : Dorso-central bristles 2 in front of suture, 3, or 

 more commonly 4, behind suture ; anal and axillary veins both 

 straight and abbreviated; eyes often hairy. Usually large, 

 stoutly-built species, with plumose arista and frequently spotted 

 abdomen. 



Antiiomyinte : Dorso-central bristles 2 in front of suture, 

 8 behind ; anal vein extended (though faintly) to margin; eyes 

 very seldom hairy ; abdomen never with the characteristic 

 " Limnophora" spots, and never stout and rounded, but more 

 elongate.
