TIScniERIA. 2(V.i 



Common at SaiKlcrstoad, aiul in many otlier looalilics, in Juno; 

 (lie perfect insects appear very slncrtrish. The larva mines the 

 upper part of the leaves of the Dact)jlh r/lomeraia in May.

Head beJilnd with raiher erect hairs, \\\ front smooth. Labial palpi 

 short, filiform, droopina;. Tongue of moderate length, clothed with 

 scales. Antennas considerably sliorter than the anterior wings, in the 

 ^ with pilose cilialioi/s, in the ? simple, the basal joint furnished 

 with a projecting tuft of hair. Wings with long cilia, the anterior 

 pointed, hardly caudulate, the posterior lanceolate. Hinder tibiaj 

 luiiry. In the anterior wings the discoidal cell is not closed, the sub- 

 costal vein is obsolete for a considerable length towards the base ; it 

 sends five veins to the costa, the median emits three to the hinder 

 margin, the subdorsal vein is simple ; in the posterior wings the 

 veins are simple. 



A rather singular genus, of which only two species have oc- 

 curred in this country (two or three others arc known on the 

 continent) ; the perfect insects sit with the head slightly raised, 

 the tips of the wings firmly ])rcsscd against the substance on 

 which the insect is sitting. The larvte are leaf-miners, and re- 

 markable for their extremely vuidevelopcd legs, whicli require to 

 be seen by the aid of a microscope ; the liabits of our two species 

 exhibit considerable diU'erences.
