LISPE. 147 



very slightly curved; discal transverse vein slightly oblique, hardly 

 curved inward, parted by much more than its length from the praebra- 

 chial transverse vein, and by much less than its length from the border. 

 Alulae greyish, with testaceous borders. 

 Not rare. (E. I.) 



Genus III. LISPE. 



LISPA, Latr. G. C. iv. 347 (1810); Zett. Musca p., D. G. Lispe, 

 Fal.; Meig. ; Hal.; Mcq. 



Corpus subsetosum. Caput breve. Frons lata. Facialia nuda. Epistoma 

 subprominens. Oculi nudi, in utroque sexit remoti. Palpi capitati. 

 Antennae epistoma vix attingentes; articulus tertius secundo cluplo 

 longior; arista basi supra plumata. Alae parvae. Alulae mediocres. 

 Abdomen ovatum, depressum. Pedes intermedii elongati. 

 Body slightly bristly. Head short ; front broad ; facialia bare ; epi- 

 stoma slightly prominent. Eyes bare, remote in both sexes. Palpi capi- 

 tate. Antennae nearly reaching the epistoma; third joint twice the 

 length of the second ; sixth plumose above towards the base. Wings 

 rather small ; cubital and prsebrachial veins diverging from the prae- 

 brachial transverse vein to the discal transverse vein, nearly parallel 

 from thence to the border ; discal transverse vein slightly oblique, nearly 

 straight, parted by about twice its length from the praebrachial trans- 

 verse vein, and by much less than its length from the border. Alulae 

 of moderate size ; lower valve extending much beyond the upper. Ab- 

 domen oval, flat. Legs slender ; middle legs rather long. 



These flies inhabit the sea-shore, and the borders of ponds and 

 lakes. L. adscita, Hal., and perhaps another British species, might 

 be removed from this genus.
