14. Genus EXALA, nov. gen., Meyrick 



Characters. -- Head with appressed scales. Antenna about 1, basal joint e'ongate, without 

 pecten. Labial palpi long, curved, ascending, somewhat loosely scaled, terminal joint hall second, 

 tolerably pointed. Maxillary palpi moderate, porrected, pointed, with short erect hairs internally. 

 Posterior tibia; clothed with very long hairs. Forewings elongate-lanceolate, apex produced, acute; 

 2 from towards angle, 5 and 6 out of 7, 8 absent, q out of 7, 1 1 almost from base. Hindwings two-thirds, 

 lanceolate, cilia 1 ; 5 and 6 absent. 



1 have not seen this insect, but have interpreted to the best of mv ability the particulars given 

 by Enderlein. which seem to be carefully stated; the features of the neural structure at the base "1 

 forewings are however probably misrepresented in the figure. The genus appears to be a modification 

 of Gvacilaria. 



Early stages unknown; for the larva represented as conjecturallv belonging to the species 

 (found under stones and not bred) is certainly not attributable to this family, having prolegs on 

 segment 10. 



Geographical distribution of species. — Only known from a very small southern island, 

 approximately intermediate between South Africa and Australia, but immensely remote from either.
