 Latham's collection, and the male from one in Mr. Marsham's, 

 supposed to have been taken in the neighbourhood of London. 



In the Kirbyan type-collection are two specimens of the 

 male and one of the female ; one of the former sex is much 

 fresher than the other, and is probably that referred to in the 

 above note as having been taken at Little Blakenham. The 

 only example that I have seen, that has been captured since
