Alebra Wahlbergi, Boh., Sv. Ak. Handl. 42. Plate 

 LXI., fig. 3, and Plate LXIL, figs. 1 to 1&. 



Alebra alhostriella, Edw., pt. ii., p. 79. 



Head whitish. Frons all yellow. Abdomen of female 

 flat, with a projecting saw-case. Colour brown, but 

 reddish at the apex. Legs pale yellow ; hind tibias 

 finely punctured with brown. Corium of the elytron

 figure). The under side is all yellow. 



Expanse of wings, 0-30 inch, or 7-62 millimetres.
