(Bloomfield). I took a female at Ringsteatl, in Norfolk, as late 

 as August 23rd, 1906. 



6. tabidus. — I have five specimens appearing to belong to 

 nothing but this species, which is said to prey upon Longicorn 

 beetles. Three were bred by Mrs. Holmes at Sevenoaks in 1906 

 from Eiipithecia minutata, and had spun white or pale ochreous 

 cottony, cylindrical cocoons of 5 mm. in length, from which one 

 failed to emerge, and had, as the Parasitica often do in such 

 cases, died with its head inwards ; one female was captured by 

 Wilson Saunders at Reigate in July, 1872 ; and I took the last 

 on bracken at the Wilverley Enclosure, near Brockenhurst, June 

 14th, 1907.
