*Gnoriste bilineata, Zctt.— Mr. C. G. Lamb took an insect at 

 Nethy Bridge in June, 1905, which appears to be this. The thorax 

 has a fine, paler, central line as well as the two dark side lines, and 

 may thus represent Zetterstedt's O. trilineata, which Kertesz (Kat. 

 der palaarktischen Dipteren, i, 42) identifies with bilineata. Mr. 

 Lamb's specimen does not agree with apicalis, hnrcynice, or longi- 

 rostris. The rostrum is very long, and may well reach to the fourth 

 abdominal segment ; but in its present position 1 cannot say with 

 certainty. 



* Paratinia sciarina, Mik. — A single male of this species was taken 

 at Carrow Abbey, outside Norwich, on June 1.3th, 190 t. A specimen 

 taken at Crowborough in April, 1901, is smaller, and the sides of the 

 thorax are yellower ; it seems to be another species. 



The genus Paratinia (Mik, Verb, zool.-bot. Ges. Wien, xxiv, 333 

 [187-1]) differs from Polylepta by the long cell, straight cubital vein, 

 equal length of third and fourth joints of palpi, spineless tibiae, and 

 long hairs on the wing ; the fork of vein 5 is almost directly under the 

 small cross vein ; from Empalia by the spineless tibiae, long cell, and 

 long stalk of vein 4, which last character also separates it from Lasio- 

 soma ; in Empheria the eyes are round, the costal cross vein is over 

 the cell, and the fork of 5 is nearer the base. 



* Polylepta undulata, Winnertz. — This is the only species of the 

 genus that I have taken or seen (Logie, August 27th and 29th, 1903 ; 

 Crowborough, June 28tli, 1903 ; and in the New Forest by Dr. Sharp, 

 June, 1903). Specimens standing as P. splendida in Mr. Verrall's 

 collection agree with mine. The distinctive marks, according to 

 Winnertz, are the following : in P. splendida the fore tarsus is 

 1^ times the length of the tibia, the metatarsus three-fourths of the 

 tibia, and the fork of 5 is under the fork of 4 ; in P. undulata the 

 fore tarsus is 2| times the tibia, the metatarsus H, and the fork of 

 5 is much nearer the base. 



*Hertioigia niarginata, ! >ziedz. — The genus Hertwigia, Dziedz. 

 (Pam. Fiz. V [1885]) "differs from Telragoneura by the greater length 

 of the mediastinal vein, which joins the subcostal over the cell, also 

 by the forking of vein 5, and the course of vein 3 " (which in Tetrago- 

 neura is almost straight, in Hertivigia bent where the cross vein 

 meets it). 



" From the other Sciophilince it differs by the fact that the medi- 

 astinal vein in the other genera ends in the costal vein, whereas in 

 Hertwigia it joins the subcostal vein. From Paratinia it differs in
