466 TIPULIDvE. 



longitudinal, and is equal in length to the petiole ; second sub- 

 marginal cell also with a short petiole ; the small cross-vein 

 situated a little beyond middle of discal cell ; the latter closed, 

 elongated, its inner half cuneiformly narrowed, and its inner end 

 a little before the origin of pra?iurca ; the great cross-vein a short 

 distance beyond inner end of discal cell ; fourth longitudinal vein 

 originating in fifth longitudinal at a little before one-third the 

 length of the wing, joined at its base to first longitudinal by a 

 short cross-vein ; fifth, sixth, and seventh longitudinal veins 

 straight. 



" The most striking peculiarities in the venation are, the course 

 of the first longitudinal which terminates in the second, the 

 absence of the marginal cross-vein, the first and second sub- 

 marginal cells being both petiolate, the position of the small 

 cross-vein, and lastly the shape and position of the discal cell. 



" This genus seems undoubtedly related to Gonomyia."

Range. Australia and India. 



The prffif'urca (that is, the basal section of the 2nd longitudinal 

 vein from its origin to its fork) is shown in Skuse's own plate as 

 beginning just before the middle of the wing and not after it, as 

 he says in his description of the genus. It originates in my new 

 species at the same spot as in L. singularis, Sktise. 



The auxiliary vein ends at the middle of the wing ; the 1st 

 longitudinal vein extends to about three-fourths of the wing and 

 turns down, meeting the 2nd longitudinal at (kingularis) or just 

 beyond (lengalensis) its fork, thus dividing the marginal cell into 

 two parts. The 2nd vein begins a little before the middle of the 

 wing at a rather wide angle, turning up rather angularly before 

 the middle of the pra3furca, and forking at a little beyond ils 

 entire length (bengalensis) or at two- thirds of its length (singu- 

 7cmY), the branches diverging at their tips. The upper submargina. 1 

 cell is subtriangular (singularis) or elongate-conical (berigalensis). 

 The 3rd vein originates at the angle in the pra3furca and is nearly 

 straight, ending at about the wing-tip or just below it ; the 

 anterior cross-vein placed distinctly before the origin of the 3rd, 

 of ordinary length, and over the middle of the discal cell, which 

 latter is elongate, about three times as long as broad, rather 

 irregular in shape with its inner end pointed. The 4th vein has 

 the upper branch forked, the lower prong with a rectangular basal 

 section which forms half the distal side of the discal cell, the 

 discal cross-vein forming the remaining half. The lower branch 

 of the 4th vein simple, slightly sinuous in both the known species; 

 the 5th, 6th and 7th veins nearly straight. Posterior cross-vein 

 just beyond base of discal cell (singularis) or a little before its 

 middle (bengalensis}. Anal angle of wing somewhat rounded.
