768 TINEINA [ZELLBEIA 



on anterior half ; a dark fuscous costal spot before middle, 

 meeting a curved oblique fuscous streak extending from J of 

 dorsum to middle of disc, thence indistinctly continued to apex, 

 often interrupted ; an indistinct dark costal anteapical spot, 

 edged with whitish suffusion ; a black subbasal line in cilia 

 only distinct round apex. Hindwings grey, paler anteriorly. 



Edinburgh (Pentland Hills), local ; Finland, Bavarian Alps ; 

 9, 10. 



3. Z. saxifragae, Stt. 12-15 mm. Head white, sometimes 

 mixed with light fuscous. Forewings white, sprinkled with 

 pale brownish four longitudinal series of black dots, upper- 

 most only on anterior half ; a curved oblique dark brown 

 streak extending from J of dorsum to middle of disc ; an 

 indistinct often interrupted longitudinal brownish suffusion 

 from extremity of this to apex of wing; a black subbasal 

 line in cilia round apex, reaching tornus. Hindwings grey, 

 paler anteriorly. 



Perth, local ; Swiss Alps ; 6, 7. Larva greenish ; dorsal line 

 reddish ; subdorsal dark reddish, interrupted ; head yellow- 

 brown : in hearts of Saxifraga aizoides ; 5, 6. 



20. SWAMMERDAMIA, Hb. 



Head rough. Tongue short. Antennae f , in $ minutely 

 ciliated, basal joint moderate, without pecten. Labial palpi 

 moderate, porrected, second joint somewhat rough -scaled be- 

 neath, terminal as long as second, pointed. Maxillary palpi 

 rudimentary. Posterior tibiae smooth-scaled. Forewings : 1 b 

 simple or furcate, 6 absent, 7 to termen. Hindwings 1, elon- 

 gate-ovate or ovate-lanceolate, with transparent subbasal patch, 

 cilia 1-1J; 4 absent, 6 and 7 parallel. 



A small genus confined to Europe. The position assumed 

 in repose by the imago is that of Zelleria, and in this instance 

 there can be little doubt that it assists (in conjunction with 

 the colouring) in producing a protective resemblance to the 

 droppings of birds. Imago with forewings elongate. Larva 

 certainly often very variable and assuming different forms 

 locally, beneath a slight web on upper surface of leaves. Pupa 

 in dense white cocoon.
