SUPPLEMENT TO ANNOTATED LIST OF BRITISH ANTHOMYIID^. 



BY R. H. MEADE. 



Since the last portion of my List was published in October, 1883, 

 I have found a few British species of AntliomyiidoB which appear to be 

 new, and a considerable number of others which were unknown to me 

 at the time of the compilation of my paper. I purpose, therefore, to 

 go through the different genera into which the Family has been 

 divided ; shortly to describe those species which seem to be new ; to 

 record all additional ones which have come under my notice ; to amend 

 several errors into which I had fallen ; and, finally, to add a few sup- 

 plementary remarks, which may be of interest. 



POLIETES, Eond. 



The few species included in this genus resemble some of the true 

 Muscida, by having their bodies softer and less spinose than those of 

 most of the other larger Anthomyiidce ; Eob. Desvoidy, therefore, 

 placed them in his genus Macrosoma, between the genera Grapliomyia 

 and Mesembrina, but, as he afterwards acknowledged, this was a mis- 

 take, for the widely open extremity of the first posterior cell of the 

 wing is an essential character of all Authomids. 



P. HIETICEURA, Sp. 71. 



Mas, cceruleo-nigra nitida, puree tenuiterque setosa. Thorax vittis albi- 

 dis striatus. Abdomen glauco-cinereum, linea dorsali nigra, tessellisque nigris 

 signatum. Oculi longe-hirti. Calyptra squamis aureis. Halteres olscuri. 

 Alee hyalincE, nervis transversis obliquis, sed rectis. Tibice posticce arcuatce, 

 denseque villoscB. Long., 9 mm. 



Male, shining steel-blue ; antennte, palpi and legs black. 



Head : eyes sub-contiguous, thickly clothed with long yellowish hairs ; face 

 with glistening white reflections ; cheeks small and reddish-brown ; mentum grey, 

 thickly clothed with black hairs and bristles ; vibrissse extending about half way up 

 the facial groove ; antennae rather short, third joint scarcely twice as long as the 

 second ; arista long, thickened at the base, thinly clothed with hairs of a moderate 

 length to a little beyond the middle, extremity long and bare. 



Thorax with scutellum shining blue-black ; the former is marked with five 

 silver-grey longitudinal stripes, which are very distinct at the sides and front margin, 

 but become pale behind ; they divide the dorsum into four blue-black bands, the 

 outer pair of which are twice as wide as the inner pair ; the dorsal bristles are small 

 and weak, but the sides are furnished with numerous hairs and setae. 



Abdomen bluish-grey, showing white and black reflections ; it is mai-ked down 

 the back with a longitudinal central black stripe, which is dilated into a large trian-
