Habitat in Ja]:)onia. 



In Mus. Hopeiano Oxonia}. 



The bead and thorax are clothed with a fine sericeous 

 coating, giving them a greyish colour. The wings are 

 fulvous, the anterior margin being rather more deeply 

 coloured. The veins are dark fulvous, having a moderate- 

 sized brownish patch towards the base, followed by a small, 

 nearly central spot, and an irregvilar and much broken 

 bar between the middle and apex of the Avings. The legs 

 are comparatively thick, and covered with fine, short 

 hairs. The halteres are luteous buff.

 totum capitis occupantibus, supra et infra coalitis ; nasus 

 mediocrife ; palpi breves, 4 ?-articidati. Antennas breves, 

 graciles, 14-articidatro, articulo Imo longiori, 2ndo bre- 

 vissimo, reliquis sensim attenuatis, singulo setam longam 

 supra emittenti. Thorax compressus. Abdomen breve, de- 

 pressum, thorace duplo longius. ALt; elongate, anguste, 

 venis in parte apicali alarum simplicibus (nee furcatis), 

 parallelis; venis analibus gracillimis versus basin curvatis, 

 vena cubitali unica Integra, venis tribus externo-medianis

0/js, — The venation of the wings in this genus is quite 

 unlike that of any other Tipulideous insect with Avhich I 

 am acquainted. Its peculiarities will be best understood 

 by a reference to the figure of the Aving (fig. Gb). It is 

 not easy to speculate on the near affinities of so anomalous 

 an insect. 



Libnotes Tliicaitesiana. 



Capite nigro, antennis et palpis fuscis; thoraceet ab- 

 domine laste testaceo-fulvis ; alis limpidis, costa tenui venis-
