Antenna brown ringed with white. Forewing ochreous brown, mottled with yellowish scales near base(wornspecimenstendtobecomemoreuniformyellowish-brown).Twowhitefasciae.Firstfascia oblique from 1/4 of costa towards 1/2 of dorsum, ending beyond fold. Second fascia almost straight,from3/4ofcostato3/5ofdorsum.Severalwhitespotsnearoutermarginofwings,eitherabsent or condensed into a narrow streak. Fringe coloured as forewing, with obscure lines. Hindwing brown to dark brown.

Remarks. Dirhinosia trifasciella wasdescribedbyREBEL (1905)fromasingle female originating from Bulgaria. We were able to examine the holotype whose genitalia are prepared on NHMW slide 3435. After examining this specimen,weconsideredthat D. trifasciella and D. cervinella wereidentical.Wesenta drawing of the holotype female genitalia to Dr ALEXANDR LVOVSKY at ZIAP for comparison with the type material of cervinella from the EVERSMANN collection. He confirmed our view that the female genitalia of syntypes of cervinella are conspecific with those of trifasciella . The first record of Dirhinosia cervinella in Central Europe ( Hungary, Gyöngyös) was identified mistakenly as Chionodes lugubrella (FABRICIUS,1794)( BUSCHMANN 2000) . D. cervinella resembles lugubsrella externally, but the ground colour of the forewing of the latter is dark brown without any yellowish or reddish tinge.
