the first cylindrical, about the length of second and third taken 

 together. Thorax covered with yellowish-grey bloom, with brown 

 stripes and spots"*; two more or less distinct, somewhat irregular, 

 intermediate stripes terminating at transverse suture ; two lateral 

 ones from below humeri to above origin of wings ; a roundish spot 

 on each side at the back of mesothorax ; a deep brown stripe on 

 lateral border from collare to origin of wings ; pleurae covered 

 with a greyish or yellowish-grey bloom, with a short brown stripe 

 midway between origin of wings and fore coxse ; scutellum and 

 metathorax more or less covered with greyish bloom, the scutellar 

 pits distinct, brown. Halteres ochreous-yellow, the club usually 

 slightly infuscated. Abdomen brown ; the posterior margins of 

 segments and venter more or less ochreous ; genitalia reddish- 

 testaceous, similar in structure to L. Lawsonensis. Legs ochreous 

 or dull testaceous ; the joints ringed as in L. Lawsonensis. Wings 

 sub-hyaline, in both sexes spotted exactly as in the $ of L. Lawson- 

 ensis ] venation very similar to that of last species, except that the 

 anterior branch of second longitudinal vein in all cases joins the 

 costa beyond the tip of first longitudinal vein a distance at least 

 equal to its length. 



Hah. — Woronora, and Knapsack Gully, Blue Mountains, N.S.W., 

 5 (?> 7 9 specimens (Masters and Skuse) ; King George's Sound, 

 Western Australia (Masters), two 9 specimens in Coll. Australian

Like Li77i. geniculata (Meigen, Syst. Beschr. II. pi. 2, fig. 15,

* The pattern in the thorax seems only a modification of that in L. 

 Lawsonensis.
