terruptecl wliite fascia) on the sides and front margins of the rings, which have also 

 both discal and marginal setse ; wings with apical cross vein neai*ly straight and 

 curved at the bend, outer cross vein straight, fifth vein sometimes abruptly shortened 

 a little before reaching the margin of the wing, when the specimen has been looked 

 upon as a distinct species from D. ornata, Mgn., in which the vein extends for its 

 full length ; legs black. Not common ; in the Eev. E. N. Bloomfield's, Mr. Dale's, 

 and Mr. Billups's collections. 



D. BLAND A, Fin. 



Eyes rather widely separated, frontal stripe black or brown, rather narrower 

 than the sides of frontalia, which are white with black reflections ; face and cheeks 

 silvery-white ; antennse long, third joint nearly six times as long as the second ; 

 arista thickened to about the middle ; facialia ciliated about half way up ; palpi 

 black ; thorax shining black, with three glistening white stripes, the middle one 

 shortened, thus leaving two black bands ; post-sutural outer dorso-central setae three 

 in number ; abdomen shining black, with a narrow white continuous band on the 

 front margin of the second, third, and fourth segments, which have both discal and 

 marginal seta? ; wings with apical cross vein straight and curved at the base ; legs 

 black, with the fore tarsal joints dilated in the female. This well marked species, 

 which varies a good deal in size, is rare ; I have only seen one British specimen, 

 which I captured at Windermere in June, 1884. 



D. PULCHELLA, Mgn. 



minima, Mcq. ?. 



Sides of frontalia glistening black in the female ; eyes of male approximated ; 

 face glistening white ; antennae with third joint three to four times as long as the 

 second ; arista thickened nearly to the middle ; palpi black ; thorax shining black, 

 unstriped, with shoulders a little grey ; abdomen bright black, elongated and narrow 

 in the male, with slight white reflections on the sides, and a very slender pale grey 

 band round the front edges of the second, third, and fourth segments, which have 

 both discal and marginal setse ; wings and scales brown in the male ; the former 

 with the apical cross vein rather oblique, straight, and curved at the base ; legs black. 



D. w/»iwa, Mcq.,is described as having the arista only thickened along its basal 

 third, instead of to about half its length, and also as being much smaller than D. 

 pulehella, otherwise they ai'e very similar; the question of size is of no importance, 

 it is so variable in many of the Tachiniidce, so I believe they are only varieties of 

 the same species. Rare ; both forms are in Mr. Dale's collection, and were captured 

 at G-lanvilles Wootton. 



D. ORANDICORNIS, Zett. 



Frontalia wide in the female, middle stripe piceous, and wider than the sides ; 

 antennae with third joint long and thick ; arista thickened to beyond the middle ; 

 palpi black ; thorax shining black, with white reflections in front, and marked by 

 four black stripes ; abdomen conical, black, and glabrous, with a narrow white band 

 round the front margin of the second, third, and fourth segments ; wings with the 

 fourth vein bent at an angle, outer cross vein sinuous, and fifth vein not quite 

 reaching the margin of the wing. This rare species is in the Rev. E. N. Bloomfield's 

 collection. Only the female is known, which closely resembles that of D. collaris,
