BRITISH ICHNEUMONS. II7 



it differs in its paler legs, prominent eyes, sub-obsolete femoral bands, 

 deeper and more eoarsely striolate gastrocaeli, flavous markings, and 

 more ample flavescent wings ; from Amhlyteles pallidicornis^ Grav., it 

 differs, besides the generic characters, in its immaculate seventh seg- 

 ment, &c. The abdominal coloration of the $ is quite unlike that of 

 /. sanitorius, which it closely resembles in structure and contour ; the 

 antennae are, however, longer than half the body, the cheeks are not 

 buccate and the pale-marking of the apical segment is extended to its 

 ventral surface. 



The types of this species are not in Desvignes' collection in the British 

 Museum, where is but a single $ labelled " Whittlesea Mere ; H. Squire," 

 which was mixed with /. snrcitorius. They may, perhaps, be found in the 

 Curtis collection, in the Victorian National Museum, at Melbourne. 



I possess a single ? , captured by Mr. E. C. Bedwell, on September 

 nth, 1900, at Kessingland in Suffolk, probably on the coast sandhills; it is 

 possible that the original examples are from the same locality, since Curtis 

 collected somewhat extensively about Covehithe, &c., in 181 2-1832. I 

 have found the $ by no means uncommonly on the flowers of Angelica 

 sylvestris, near Lyndhurst, in the New Forest, from 6th to 19th of August ; 

 and I noticed they were sometimes caught in the act of feeding and killed 

 by a white spider, Misumena vaiia, Clk., which lurks, almost invisibly with 

 wide-spread legs, upon the flower-tables. The $ of this species appears to 

 be unknown upon the Continent and the $ to be considered a variety 

 (probably viutabilis. Berth.) of /. sarcitorius, from which Dr. O. Schmie- 

 denecht tells me he does not think it differs. I do not think it possible 

 to be a variety, so constant are the markings and coloration of these two 

 species ; it is, nevertheless, worthy of note that, while it is abundant 

 throughout the country, /. sarcitorius has never been taken, to the best of 

 my knowledge, in the New Forest, where alone I have found /. laiitatorius 

 of frequent occurrence.
