longitudinal vein and small cross-vein ; in most species it is short. 

 Discal cell more or less square, usually longer than wide ; in D. 

 punctipennis about four times longer than wide. The great cross- 

 vein usually close to or at the inner end of the discal cell, but in. 

 D. remota a distance more than its length before it. 



290. DlCRANOMYIA PUNCTIPENNIS, Sp.n. (PL XXL, fig. 1). 



9. — Length of antenniTe 0*050 inch .,. 1-27 millimetres. 



Expanse of wings 0-340 x 0-090... 8-62 x 2-27 



Size of body 0-280 x 0-040... 7-10 x 1-01 



Head, including rostrum, palpi and antennae, brownish-black, 

 the head pruinose with greyish ; rostrum rather prominent. 

 Thorax dull dusky brown, pruinose with greyish, with three 

 umber-brown stripes, the lateral ones extending posteriorly 

 beyond the suture; mesosternum dusky brown, pruinose with 

 greyish. Halteres pallid, the club somewhat infuscated. Abdo- 

 men dark brown, ovipositor ferruginous-brown. Legs brown ; 

 coxae ochraceous ; femora more or less ochraceous for their basal 

 half, those of the fore legs often entirely brown. Wings almost 

 hyaline, stigma pale ; origin and tip of all veins (except tips of 

 third longitudinal vein and anterior branch of fourth longitudinal 

 vein), and all cross-veins, slightly clouded with dark brown ; 

 seventh longitudinal vein somewhat bisinuated, with a very small 

 brown spot on each curve above. Auxiliary vein reaching the 

 costa beyond the origin of the prsefurca, sometimes a distance 

 equal to the length of marginal cross-vein ; sub-costal cross-vein a 

 little before origin of prsefurca ; first longitudinal vein suddenly 

 strongly arcuated before its tip, the marginal cross- vein at the 

 middle of this bend, and situated from the tip a distance usually 

 rather greater than its length ; the latter consequently shortened 

 and straight ; prsefurca and that portion of third longitudinal vein 

 before small cross-vein almost in straight line, both distances 

 equal or the first a little longer ; small cross- vein very short ; 

 discal cell closed, about four times longer than broad, the great 

 cross-vein a little before, at, or somewhat beyond its inner end.
