ably larger. Klug does not mention the colour of the mouth, but 

 in some specimens in my collection (agreeing otherwise with the 

 description) that is white. In an example in my collection there 

 are still, firmly attached to one of the fore tarsi, two pollinia of an 

 orchid ; they point straight out, and afford clear evidence that 

 this Athalia aids in the fertilization of these curious plants. 



6. LUGENS, Klug, 



is a commonly distributed species. I have taken it near 

 Gloucester, Manchester, and in our neighbourhood at Kilsyth Glen, 

 and Mr Morris Young has captured it on the Gleniffer braes. 

 Under the name of Athalia ahdo?ninalis, Fab. (which is a synonym 

 of higens), Kaltenbach (quoting Bouche, Stett. Ent. Zeits. xii., 

 p. 290), describes a larva which may refer to higens. He states 

 that the female bores into the young branches and leaf-buds of 

 Clematis erecta, and deposits her eggs therein ; and in course of 

 time a bladder-like swelling is formed, wherein the brown-headed 

 larvae live until they are about half-fed, a period extending from 

 14 to 20 days ; after this they become external feeders, assume a 

 brownish-green colour, and devour the edges of the leaves for 14 

 to 20 days more, when they drop down to the earth, where they 

 pass the winter. Supposing this to refer to Ingens, it is certain 

 that it must have some other food-plant besides Clematis, since it 

 is found in places where no Clematis is native, or grows at all — in 

 Clydesdale, for example. There is probably some confusion about 

 the matter. 



7. Annulata, Fab., 



is apparently the rarest of the species. It is described as British 

 by Stephens, but there are no specimens of it in his collection in 

 the British Museum, those under the name of annulata being 

 rosae. I think the species is certain to be British, but it must at 

 present be erased from our lists. Kaltenbach says that he found 

 the larva in July, and again in September and October, on 

 Veronica beccahinga, whose leaves it eats on the under side. The 

 larva is dull black, whitish on the sides, and spins a cocoon in the 

 earth. According to the same author, the fly appears in the 

 Spring and during the Summer on flowers, especially those of 

 Heracleum. 



I may add that I have found a similar larva on Veronica, but
