576 Mr. E. Bergroth on a new 



Head rouncled ; I'ostrum as long as the vest o£ the head ; 

 antennse 16-jointed, joints with verticillate hairs. Thorax 

 longitudinally moderately convex ; pronotuni 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, Sc2 placed a little before the base of 

 the moderately curved sector, which originates behind the 

 middle of the wing ; no radial cross-vein ; R2 and tiie apical 

 half of R3 strongly upturned, parallel or slightly convergent, 

 R2 joining margin of wing a little in front of or at apex o£ 

 Ri, cell R3 about four times longer than cell R2, M two- 

 branched, Ml and M3 fused ; median cross- vein present, 

 roundedly confluent with M3, 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 M3 entirely lacking 

 and discal cell consequently confluent with cell M3, ascending 

 portion of Cui 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 Gonomyia^ from which 

 it differs by the narrow petiolate wings, the position of 

 Sc2 which is more removed from the tip of Scj, and the 

 shape of cell R2 which is very short and subrectangular 

 owing to the strongly upturned apical half of R3 — a course 

 of this vein not known in any previously described Tipulid 

 genus. The propygium is also somewhat differently con- 

 structed than in Gonomyia. The disappearance of the basal 

 part of M3 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 Dicranomyia.
