The wing appears larger and broader, the veins more separated, 

 generally speaking. The subcostal cross-vein is at the absolute 

 tip of the auxiliary vein. The tip of the wing is represented in the 

 figure as missing, but the end of the ist longitudinal vein can be 

 plainly seen, and it is shorter than in Cladura, running straight to 

 the wing-margin ; the marginal cross- vein being placed shortly after 

 the fork of the 2nd vein, which forking takes place just opposite 

 the tip of the auxiliary vein. The praefurca originates at one- 

 third of the length of the wing, and is nearly as long as the 

 remainder of the vein, and nearl}'' in a line with the 3rd vein, 

 which ends much below the tip of the wing, in which latter pecu- 

 liarity it differs from Cladura and my two new genera, in all of which 

 it ends exactly at the tip of the wing or immediately below it. 

 Discal cell pointed at proximal end, the anterior cross-vein joining 

 the 3rd vein immediately^ after its origin, and the lower end of it 

 situated at one-third of the discal cell. Anterior branch of 4th 

 vein simple, parallel with the 3rd vein ; lower branch widely forked 

 soon after the cross-vein which closes the discal cell. The discal cell 

 is composed of a proximal triangle combined with almost a distal 

 square ; four sided : the whole upper side forming a slightly curved 

 line, the lower side two lines ; the outer side is the discal cross-vein, 

 upright ; the posterior cross-vein placed at the angle formed b}' 

 the two lower sides of the discal cell. The 5th vein bent consider- 

 ably at its junction with the cross-vein; the 6th vein nearh' 

 straight; the 7th gently bisinuate. Between the 6th and 7th is 

 shown what is apparently a spurious vein of some length, entirel}' 

 disconnected. 



PARACLADURA, mihi, gen. nov. 



Allied to Cladura, Os. Sac. Type P. gracilis, mihi, sp. nov. 



Two submarginal cells, five posterior cells, a discal cell. 



Differing from Cladura in the face being distinctly though not 

 conspicuously gibbose. The antennae are of a totally different con- 

 struction altogether; the scapal joints both being very short, sub- 

 globular, no longer than broad, whilst the flagellum is composed of 

 fifteen joints, a very unusual number throughout the famih' 

 Tipulidae. All the joints are very elongated, minutely pubescent. 

 The whole antenna if bent backwards would reach the basal seg- 

 ments of the abdomen. 



The venation affords several very marked differential charac- 

 ters. The subcostal cross- vein is situated a long distance before the 

 tip of the auxiliary vein, only a short distance beyond the base of 

 the 2nd longitudinal. 



The auxihary vein ends gradually in the costa at about two- 

 thirds the length of the wing. The ist longitudinal vein is ver3' 

 long, following the line of the costa nearly to the tip of the upper 

 branch of the 2nd longitudinal vein, and parallel to that section 

 of that vein ; thus ending itself much nearer the tip of the wing 

 than is usually the case.
