middle. It is obvious from tlie arratij^emeut of the folds 

 that the wing is Cii|>al)le of Hrst fohling up fanwise, and tlien 

 doid)[iii':; up so as to occupy the suiallest possible space. In 

 order to deuioustrate this completely I iuad(; a |>aper luodel 

 of the winj:^, aiul oljtaiucd the expected result by foldin<:^ it 

 carefully along the lines of the " secoiulary venation," coni- 

 meuciug from the anal angle. Since there is no hard costal 

 margin (as in the earwig) ou •which the M'ing can fold b;ud<, 

 it is unlikely that the folding actually takes place after 

 emergence ; it is much more probable that, as in the 

 l^lcpharoceridae, the " secondary venation " merely marks 

 the manner in which the wing was folded in the pupa. This 

 folding of the imagiu.il wing within the pn])al envelope occurs, 

 so far as I am aware, only in the families Blepharoceridre 

 and Simuliidse, and almost certainly indicates a relationship 

 between the new genus and one or both of these families. 

 The very regular arrangement of the folds in the new 

 genus is quite unlike the irregular network found in the 

 Blepharoceridie, in which fainily, moreover, the folds 

 generally beconievery faint wiien the wing is fully expanded 

 and hardened. The basal selerites of the wing are very 

 peculiar, the attachment being unlike that found in either 

 of the families mentioned.

Hah. Kashmir : Srinngar, 11,000-12,000 ft., July or early 

 August {F. J. MUchell). Cotypes, two males in the IJritisli 

 Museum, presented by Mr. M. E. Mosely, Oct. 1921 — one 

 dissected and mounted in balsam, the otner in formalin, one 

 ■wing removed and mounted dry. Mr. Mitchell unfortunately 

 kept no notes as to the habits of the flies, but wrote on 

 2r).xi.l921 that "■ the area in which the collection was made 

 is now probably under G ft. of siiow, increasing po.ssibly to 

 20 ft. or 30 ft. in the spring."
