At present not much is known about the immatiu"e stages of most 

 species of Walshiidae; however, some general statements can be made. 

 The known larvae of Ithome feed on the florets of species of Legu- 

 minosae and Polygonaceae. The larvae of Walshia miscecolorella 

 (Chambers) and W. amor'phella Clemens are stem and root borers; 

 W. miscecolorella has been reared from several species of Leguminosae 

 and is potentially a pest of sweet clover in parts of Texas. The larvae 

 of W. amorphella are gall formers on the stems of Amorpha fruticosa 

 L. and occasionally on Hydrangea spp. The known larvae of species 

 of Aeaea Chambers are leaf miners in Ostrya virginiana (Mill.) K. 

 Koch., Quercus spp., and Rhynchosia tomentosa (L.) H. & A. Species 

 of Periploca (Braun) are known from Ceanothus spp. (gall formers on 

 the stems), Gleditsia spp., and Rohinia spp. (borers in the thorns), 

 Juniperus spp. (found in the fruits), Gymnosporangium spp. (in galls 

 and as a twig girdler). Two species, Periploca laeta Hodges and P. 

 nigra Hodges, sometimes are pests of ornamental junipers. Perimede 

 erransella Chambers has been reared from Taxodium spp. and leaves 

 of Ulmus spp., but whether this species is a miner during all or part of 

 the larval stage or whether it is an external feeder is not known. Obithome 

 punctiferella (Busck) has been found in cages which contained cotton 

 bolls, but whether the larva feeds on the bolls or is a scavenger is 

 unknown. The larvae of Stilbosis tesquella Clemens are external feed- 

 ers on Amphicarpa spp. and Lespedeza spp. The larvae of Chryso- 

 peleia purpuriella Chambers have been reared from the leaves of 

 Rohinia pseudo-acacia L., but the exact habits are not known. Sorha- 

 genia rhamniella (Zeller) and S. nimhosa (Braun) are leaf folders on 

 Rhajnnus spp. in the larval stage. 



Because the species of Aeaea Chambers have similar maculation 

 and habitus, it was necessary to make genitalic preparations of each 

 specimen. In some of the female abdomens, single larval head cap- 

 sules were found. Dm'ing the process of cleaning the specimens, the 

 head capsules were often removed; but they are present on two slides 

 (RWH slides 1167 and 2121), Aeaea "d" and Synploca gumia, new 

 genus and species, respectively. These head capsules indicate that 

 the species possibly are ovoviviparous, a condition known to occur in 

 the Coleophoridae (Toll, 1952), Tineidae (Diakonoff, 1952), and 

 Oecophoridae (teste Clarke).
