3. Cyrtoma simplicipes, Zett. Another widely distributed species 

 of this genus easily recognised by its very slender hind tibiae. It has 

 occurred from Dorset to Aviemore and the Isle of Arran. 



4. BJiamj)homyia obscum, Zett. This is a moderately small brownish- 

 black species (3 mm.) with practically uniserial dorso-central bristles 

 and biserial acrostichal bristles on the thorax, best distinguished in the 

 male by the curious downwards loop at the base of the wire-like penis, 

 and in the female by the way in which the legs are ciliated, the middle 

 femora bearing pennate bristles at the tip beneath, and the hind 

 femora with a distinct pennate ciliation beneath. I have examined 

 only a pair taken by Mr. J. J. F. X. King at Kilmun (Argyllshire), 

 on June 16th, 1906. 



•5. Bhamphomyia hirtula, Zett. A pair of this species in the late 

 Mr. Verrall's collection were taken at flowers by Mr. I. H. Bui-kill at 

 Clova (Forfarshire) when making observations upon flowers and insects 

 in that locality. It is a most interesting addition to our fauna because 

 it has previously only been recorded from Greenland by Zetterstedt 

 and Lundbeck. It is a hairy species, as its name implies, and some- 

 what allied to fumipennis, Zett., but the upper laniellsB of the male 

 genitalia are notched above, and the penis is thin and wire-like. 



6. Bhamphomyia tibialis, Meig. Two males of this species were 

 taken by Col. Yerbury at Aviemore (Inverness- shire) on May 21st, 

 1904. It is allied to sulcata. Fall., but the male may be known by 

 the little cluster of spines on the dorsal side toward the end of the side 

 lamellae ; the female has the hind tibiae broader than the femora and 

 with a pennate fringe on the dorsal surface. 



7. Bhamphomyia nigripennis, F. We possess in Britain both B. nigri- 

 pemiis and nmbripennis as distinguished by Lundbeck (Dipt. Danica, 

 III) . The present species was labelled umbripennis in the Verrall collec- 

 tion, and umbripennis (of Lundbeck) was labelled holosericeus, Zett, 

 {nee Mg.). It is not at all an uncommon species in numerous localities 

 from Brockenhurst (Hants) to Spey Bridge (Inverness) . 



8. Bhamphomyia hijbrida, Zett. The sexes of this species differ 

 in colour, the male being a black, dark-winged insect resembling 

 culicina, Fall., but differing in the form of the genitalia, and in having 

 a distinct bristle beneath the hind femora, while the female is yellowish, 

 resembling /avrt, Fall., but the thorax is indistinctly striped and the 

 basal joints of the antennae are darker. It is possible this may be the 

 B. sciarina, Fall., of the " List."
