lii the characters of the loss of r and the reduction or loss of the 

 tibial spurs this group suggests Phyllolabis, O.S., of the northern 

 Holarctic region. 



LlMNOPHILA (LlMNOPHILOMYIA) LACTEITARSIS, sp. n. 



General coloration, including the wings and halteres, brownish-black ; 

 legs black, the tips of the posterior tarsi creamy-white ; antennae of 

 the male elongated ; tibial spurs microscopic or lacking ; wings with r 

 and cell J/j lacking, the deflection of J^ 4 + 5 in direct alignment with 

 the radial sector. 



Male. Length 7 mm.; wing 7'7 mm.; hind leg, femur 7'3 mm., 

 tibia 7'1 mm. ; antenna about 4'3 mm. 



Frontal prolongation of the head very short, light brown, running 

 cephalad into a shiny chitiuised median point. Lower lip triangular, 

 pointed. Palpi dark brown. Antennae of the male 16-segmented, 

 dark brownish-black ; the organ is elongated, about equal to twice the 

 length of the combined head and thorax ; scapal segments small, 

 the flagellar segments greatly elongated, the first segment longest, the 

 remaining segments gradually shortened to the end of the organ ; 

 flagellar segments cylindrical, densely clothed with a rather long 

 blackish pubescence and with a few short verticils. Head broad, dark 

 brown. Eyes contiguous beneath, the ommatidia coarse. 



Mesouotum dark brown, the praescutum a little paler and without 

 distinct stripes. Pleura dark brown. Halteres black. Legs broken, 

 excepting one of the posterior pair ; this has the coxa and trochanter 

 brown ; femur, tibia and base of the metatarsus black, the apical 

 quarter of the metatarsus creamy white, remainder of the tarsus 

 broken ; in the unique specimen at hand the writer cannot detect 

 tibial spurs, and if they are present they are very short and hidden by 

 the rather long apical tibial hairs. Wings with a strong blackish 

 suffusion, the costal and subcostal cells a little darker; stigma 

 indistinct ; veins dark brownish-black. Venation : Sc-i ending about 

 opposite the fork of Rs, Sc. 2 , projecting considerably beyond, nearly 

 four times the length of S^ alone ; Its long, almost straight ; tip of 

 R l indistinct and r lacking ; R., + 3 strongly angulated at origin ; basal 

 deflection of R 4 + :) in a straight line with -Rs; r-m a little shorter 

 than the basal deflection of M l + z ; cell 1st M z small, almost square; 

 cell M l lacking ; basal deflection of Cu l at about two-fifths the length 

 of cell 1st Mr,. Long black setae on vein R and all the longitudinal 

 veins beyond the cord, scarce or entirely lacking on the basal portions 

 of If, Cu and the anal veins. 



Abdomen rather long, dark brown, the basal stemites paler.
