576 Mr. E. Bergroth on a new 



Head rounded ; rostrum as long as the rest of the head ; 

 antennae 16-jointed, joints with verticillate hairs. Thorax 

 longitudinally moderately convex ; pronotum rather long, but 

 a little shorter than broad at the base. Wings very narrow, 

 pedunculate; axillar angle broadly rounded, Sc somewhat 

 passing base of Rs, Sc 2 placed a little before the base of 

 the moderately curved sector, which originates behind the 

 middle of the wing ; no radial cross-vein ; R 2 and the apical 

 half of R 3 strongly upturned, parallel or slightly convergent, 

 R 2 joining margin of wing a little in front of or at apex of 

 R x , cell R 3 about four times longer than cell R 2 , M two- 

 branched, Mj and M 2 fused ; median cross-vein present, 

 roundedly confluent with M 3 , but in some specimens angularly 

 joined to it and in this case emitting a short stump of a vein 

 from the angle backwards, basal part of M 3 entirely lacking 

 and discal cell consequently confluent with cell M 3 , ascending 

 portion of Cu! joining M at a good distance before the base 

 of the discal cell. Propygium elongated, median style very 

 long and slender ; lateral lobes without apical apophyses, but 

 each with two interior hooked appendages. Legs very long; 

 tibiae without spurs. 



This genus should be placed near Gfonomyia, from which 

 it differs by the narrow petiolate wings, the position of 

 Sc 2 which is more removed from the tip of Sc^ and the 

 shape of cell R 2 which is very short and subrectangular 

 owing to the strongly upturned apical half of R 3 — a course 

 of this vein not known in any previously described Tipulid 

 genus. The propygium is also somewhat differently con- 

 structed than in Uonomyia. The disappearance of the basal 

 part of M 3 and the shifting of this vein upon the median 

 cross-vein is a rather uncommon character, but occurs also in 

 some other Eriopterina, in Ellipoptera, Schin. (this is the 

 correct spelling of the name), and Thaumastoptera, Mik., and 

 in some species of Dicranomyta.
