third joint, its pale palpi and silvery white face, the tibiae are dark with only 

 the extreme base and tip pale. N. chamieleon, Becker, must be exceedingly 

 closely allied, if not identical. 



Notiphila stagnicola, Desv.— In the " List " this species is wrongly credited 

 to Macquart instead of Desvoidy. 



Notiphila macidata, Stenh.— From Stenhammer's description it is obviovis 

 that in his species there should be no ciliation beneath the middle femora, 

 therefore Schiner was correct in suggesting that venusta, Lw., was identical 

 with macidata, Stenh., which necessitates a new name being given to the 

 species called niaculata by Loew and Becker. 



Notiphila supposita, n.n. — This is the name proposed for maculata, Lw., 

 Beck., nee Stenh. I have seen it from only Herefordshire. 



Discomyza cimiciformis, Hal.— A genus Clanoneurum has been established 

 for this species by Becker (1903), and Cyclocephalomyia, Hendel (1907), a new 

 name for Cyclocephala, Strobl. (1902) is a synonym {v. Czerny, 1909). 



*Atissa durrenhergensis, Lw. — I took this species at Aldebixrgh (Suffolk), 

 on September 17th and 18th, 1907. It has black antennae and smoky wings 

 without the postical cross vein clouded. 



*Atissa limosina, Becker, like the last species has black antennte, bvit is 

 darker in general coloiiring, not even having the basal joint of the tarsi pale ; 

 the postical cross vein is infuscated. I fovmd it at Arne (Dorset) in September, 

 1906, and at Woodbridge and Aldeburgli (Suffolk) in August and September, 

 1907. 



*Athyroglossa ordinata, Becker. — This species was taken by Mr. C. G. 

 Lamb, at Padstow, Cornwall, in July, 1904. Compared with .4. glabra, Mg., 

 the thorax is more bare, the scutelhuu more rounded and shining without 

 the coarse punctuation of that species. 



Psilopa compta, Meig. — Becker considers this to be only a variety of 

 nitidida, having found specimens, in the Canary Islands, intermediate between 

 the two in the coloration of the legs. I, however, prefer to leave it in tlie 

 British List for the present. 



*Discocerina (Clasiopa) cinerella, Stenh. — This species was found by 

 Col. Yerbury at Aviemore (Inverness) and Nairn, in Jvily, 1905, and Dr. Wood 

 has taken it in Herefordshire. It is one of the larger species, of a dull 

 yellowish browTi colour with the last abdominal segment brilliantly shining 

 black, with only two bristles on each side of the yellowish face, Avith pale third 

 joint to the antenna, and pale knees and tarsi. 



*Discocerina {Clasiopa) plumosa. Fin., is the largest British species of the 

 genus, the thorax is indistinctly shining, the face nearly perpendicular and 

 flat, and the 3rd antennal joint indistinctly yellowish. Colonel Yerbury fotmd 

 it at Tarrington (Herefordshire) in August and September, 1902, and I took it 

 in some numbers in that county in August, 1910.
