3 (4) Wings without sharply defined spots (and no spots much nearer base than 



is tlie origin of radial vein) and with no clouds ... lifasciata, Schrk. 



4 (3) Wings with sharply defined spots (one or more nearer base than is the 



origin of radial yein) and with numerous clouds. 



5 (fi) Femora with two sharply defined black rings. (Very large species) 



anmdus, Mg. 



6 (5) Femora with only one sharply defined terminal black ring... 



quadrinotata, Mg. 



7 (2) Subcostal vein continued much beyond the cross vein which unites it to 



the radial vein. 



8 (17) Wings with spots and clouds, or at any rate, three black spots near costa. 



9 (11) Thorax chiefly blackish or dark, never shining clear ochreous with a single 



black middle line. (Wings more or less clouded). 



10 (13) Wings clouded all over, with spots near costa somewhat more defined ; 



joints of antonnte elongate, bearing hairs nearly three times as long as 

 each joint ( <? ), or much longer than joint ( ? ). 



11 (12) Femora with three (or at least two) clearly defined dark rings .. 



nuhecuJosa, Mg. 



12 (11) Femora with only the tip distinctly dark (a pale i-ing preceding) 



Jlavipes, F. 



13 (10) Wings with slight cloudings, and three blackish spots near costa ; joints 



of antennae oval, bearing hairs rather longer than each joint... 



nitida, n. sp. 



14 (9) Thorax shining clear ochreous, with a black middle line in front. (Wings 



not in the least clouded, but with three dark spots near costa). 



15 (16) Front femora black, the basal third luteous niffropuncfata, Schnm. 



16 (15) Front femora with only a ring just before the tip black, before which 



seems to be a paler ring trijmnctata, F. 



17 (8) Wings clear, no markings or spots at all triviitata, Schum. 



18 (1) Origin of radial vein nearly opposite end of mediastinal vein... 



macrostigma, Schum. 



L. NITIDA, n. sp. ( (? $). — Atra, nitida, alis nigro-punctatis et nehulosis, abdo- 

 mine nigro segmentis quatuor mediis apiceqtie fulvis,femoribus rujo-fiaois, omnibus 

 apice, anticis in medio nigris, tibiis tarsisque obscuris. 



This species must be exceedingly near L. pannonica, Kowarz 

 (Verb. z.-b. Wien., xviii, 213), and I should have no doubt that either 

 that or this was L. anaJis, Meig., but for Meigen's positive statement 

 that his L. analis was only L.Jlainpes, Y. ; I know, from specimens in 

 the British Museum, that Walker's L. analis is L. nitida. It comes 

 between L. nubeculosa, Mg., and flavipes, F., on the one side, and L. 

 nigropunctata, Schum., and tri^mnctata, F., on the other side, but differs 

 from all in its shining black thorax and more darkly marked wings ; it 

 is slightly the smallest of all ; the black ring on the front femora, and 

 the strongly darkened wing tip, are similar to those in L. nigropunctata, 

 but that species has the wing perfectly free from cloudings ; from L. 

 pannonica I note the following distinctions (according to description) :
