Gali'chida: — In the pupa of Cnjptoh'chia (figs. 22, 23) we have an example of the modern Pvpa 

 ohtecta, there being no eyepiece (^maxillary palpi) and no labial palpi visible, while a cremaster 

 is well developed. Both in its larval, pupal, and imaginal characters 

 the transition to the I'terophoiida', Crambida', Phycida', and I'yralida; 

 is not great, and we can thus see that these families may liave 

 descended from the Tiueina. 



Family Tahvporlda'. — This group, comprising the genera Solenobia 

 and Taheporia, has evidently either directly descended from the case- 

 bearing Tiueida; or the two families have had a common origin. They 



form a side branch by themselves and 

 are the direct ancestors of the broad - 

 winged, more recent Psychida-. Their 

 relations are shown in the genealogical 

 tree at the end of this chapter. 



The imagines have, according to 

 Stainton, no maxillary paljii, and the 

 tongue is wanting, while the females are 

 wingless. The head is broad, and in 

 fact in this group we have, so to speak, 

 Tineid Bombyces. The venation (fig. 

 50) is generalized Tineid, and it is evi- 

 dent from a long abode iu cases that the 

 features which separate the family so 

 widely from the Tineidiv are the result 

 of disuse and resulting adaptation. The 

 family had diverged considerably from 

 the Tineid source aloug a path which 

 unmistakably ends in the Psychida^. 

 Without specimens of tlie wingless 



female we are unable at present to compare them with those of 

 the Psychid;^; and we still need examples of the larv.i? (living 

 and in alcohol) to compare with those of the Tineids on the one 

 hand and those of the Psychid;^ on the other. 



The pupa of Talaporia pfieiidobombycelld ' (tig. 24) has a broad 

 head, with distinct paraclypeal pieces and glazed-eye- sutures. 

 The maxillary palpi {mx. p.) are large and well developed, extending under the eye from the 

 antenuie to the labial palpi, which are large, but short and very broad. The maxillie are present, 

 but small. The abdomeu bears no cremaster, but there are two terminal small spines which 

 may be the homologues of the anal-leg hooks of the pupa' of Psycliida;. The scars of the four 

 pairs of anterior abdominal legs are present, as in PsychidiV. 



In T. conspurcateUa (flg. 25) the maxillae are much more rudimentary, and before exuviati<in 

 concealed by the long labial palpi (mx. p.); the maxillary palpi {mx.p.) are large and triangular.
