prothoracic bristle, but differincf from Tetanocera in having shorter, more 

 Sciomyzid-like antennae and from other neighbouring genera in having only one 

 preapical bristle to the hind tibiae. Sciomyza pallida. Fin., and fuscinervis, 

 Zett., of the " List," belong to this genus, to which I now add striata, Mg. 

 {affinis, Zett.), taken by Col. Yerbury at Nethy Bridge (Inverness) in June and 

 August, and at Kingussie (Inverness), and Nairn in July. It has like 

 fuscinervis a dark median fillet or band to the frontal stripe, but differs in 

 having the tip of the antennae slightly darkened, the arista with shorter hairs, 

 frons narrower at the antennae, bristles under the hind femora of the male less 

 numerous (none in female), and the prothoracic sterniun bristly. 



Renocera fuscinervis, Zett. — I have recently seen the specimens in Zetter- 

 stedt's Collection at Limd and noted that they are as follows : — a male labelled 

 "S. fuscinervis g Scan.," a second male labelled "Fredensb. Ostrogoth," 

 and a female labelled "As ad Ostersund Jemtl. V" 40." This female is un- 

 doubtedly a Renocera. identical with strohli, Hendel, while the two males are 

 Tetanocera unicolor, Lw. The original types (a pair taken at Wilhelmina, r. 

 Ins. Lapp., p. 737) are missing, but Zetterstedt's description in Ins. Lapp, 

 applies equally well to either strohli, Hendel, or unicolor, Lw., wliile his 

 description in Dipt. Scand, Vol. v, most obvioiisly includes strobli. After 

 the description of Tetanocera unicolor by Loew, in 1847, * fuscinervis of 

 Zetterstedt was aiitomatically restricted to the secoiad species inchided under 

 that name, whicli Hendel described as strohli, therefore Hendel's name must 

 sink as a synonym. 



Aniichseta vittata, Hal. — Sciomyza vittata of the " List " belongs to this 

 genus which is distingiiished from Renocera by having two preapical bristles 

 to each hind tibia. Hendel considers Haliday's species a synonym of analis, 

 Mg., but some explanation is required in regard to Meigen's description of the 

 antennae as " rostgelb." 



Heteropteryx brevipennis, Zett. — Sciomyza hreinpennis of the " List," has 

 been made by Hendel the type of this genl^s which he separates from Antichxta 

 by its abbreviated wings, different venation, &c. 



* Ctenulus distinctus, Mg. — This sj^ecies has been taken by Col. Yerbury at 

 Tram Inn (Herefordshire), and Forth cawl (Glamorgan), it appears to be a rarer 

 insect than the next. 



* Ctenulus pectoralis, Zett. — Also found by Col. Yerbury at Porthcawl 

 (Glamorgan) in June, Torcross (Devon) in August, and Gravesend (Kent) in 

 September. Mr. Verrall took it so long ago as 1875, at UpAvare (Cambridge- 

 shire), and in 1888 at Slapton (Devon). It may be distinguished from distinc- 

 tus, Mg., by its yellowisli pleurae and its distinct sternopleural bristle. 



* Ectinocera borealis, Zett., was taken by Mr. C. G. Lamb at Nethy Bridge 

 (Inverness), and by Mr. J. R. Malloch at Bonhill (Dumbarton) in June, 1906, 

 Its elongate third antennal joint makes it a distinct looking insect. 



Tetanocera robusta, Lw. — This has generally been considered only a variety 

 of ferruginea. Fin., but is absolutely distinct. In addition to its larger size, 



* In his " Revision der Scioniyzidae," Handel erroneously refers to Zetterstedt's species as 



ruHntrvis.
