 IN THE SOUTHERN PART OF THE COUJSTY OF SUSSEX. 



BY W. C. UNWIN, LEWES. 



No IV. — Including the Leptid./E, Bombylidje, Scenopinus, EmpidjE, 



DOLTCHOPID.E, LoNCHOPTERID^E, CONOPID.E, AND MUSCID.E. 

 ( Continued from page 93. ) 



LEPTLD.E.— Westwood. 



Leptis scolopacea. — Not common. On the banks by the Winterbourn stream, 

 in June. 



L. trigaria. — It has been observed, but rarely, in the neighbourhood of 

 both Lewes and Brighton. 



L. lineola. — This species is by no means common, although frequently 

 observed in this locality in June and July. 



Chrysopila holosericea. — Frequently obtained by sweeping the flowery banks 

 in the Lewes levels, in July and August. 



BOMBYLLD^.— Walker. 



Thereva plebeia. — By the sides of corn-fields, on thistles and other composite, 

 in July and August. 



T. annulata. — Rare. Near the coast at Newhaven in July. 



Bombylius major. — Common in the Plashet and Wai'ringore Woods, and 

 also in Compton Wood, near Firle, frequenting the sunny glades in these 

 localities on bright spring days, appearing in some years as early as March, 

 but usually in April and May. Its habit of hovering in the air reminds us 

 of the interesting Humming Bird Hawk Moth, (Macroglossa stellatarum.) so 

 frequently noticed in gardens in August. 



B. medius. — In plenty on the first fine warm days of April, in the same 

 localities as the last species, but seems to prefer the sunny banks of the 

 skirts of woods. It is commonly called the Unicorn Fly and Sword Bee, 

 from its long proboscis. 



SCENOPINUS.— Cuktis. 



Scenopinus fenestralis. — Of frequent occurrence in early spring. 



EMPLOYE.— Leach. 



Empis iesseVata. — Plentiful, basking on the leaves of trees and shrubs in 

 July; commonly in moist situations near Langport and Kingstone, near Lewes. 



E. livida. — Not rare. Generally obtained by sweeping the long grass on 

 hedge banks in the neighbourhood in July. 



E. femorata. — Common. On Umbelliferce, and by sweeping. 



Hilara quadrivittata. — Very common. Hovering and sportitjg at the close 

 of day over running streams in little parties in May and June. 



Rhamphomyia sulcata. — Not uncommon among the grass by the sides of
