66 BRITISH C1CAT>M. 



Size, 0*15 inch, or 4-10 millimetres. 



Scott gives as characters for his D. I-alhum, *' Face 

 bone-white ; frons black, with three transverse pale 

 lines, the white I-shaped character across the transverse 

 nerve of the basal area of the corium : these alone afford 

 characters for easy recognition." Nevertheless, he *'is 

 not prepared to see the name positively retained." As 

 this description only fairly agrees with my specimens, 

 I have queried the synonym.
