Mr. Bignell says he received eight larvae of A. Atropos, whicli were all 

 infested by this parasite. His observations bear out those of M. Ser- 

 ville that great numbers live in the sarme larva, for he says that he 

 only kept the first batch that came out (about 20), and threw many 

 others away. Mr. Eignell sent me some of the pupa-cases of the fly, 

 which were agglutinated together in groups of six or eight, and arranged 

 side by side like cells in a honeycomb. 



This fly is interesting, as it affords an example of one species of 

 parasitic Diptcron being apparently confined to one species of 

 Lepidopteron ; and also from its habit of infesting the same larva in 

 large numbers ; the parasite being rather a. small species (about 4 lines 

 in length), and the victim a very lai'ge one. In conclusion, I beg to 

 return my thanks to Mr. Bignell for the trouble he has taken, and the 

 interest he has shown in the subject ; and I hope other entomologists 

 will follow his example.

AN ADDITION TO THE LIST OF BEITISH SUMIFTUBA. 

 BT F. S. SAUNDEES. 



In July I caught two specimens of a bug off Salia^ on Wimbledon 

 Common which I had not taken before, and on shewing them to my 

 uncle, Mr. Edward Saunders, he told me that they belonged to a 

 species not yet recorded as British, viz., Lygus Umhatus, and I there- 

 fore forward their description for the information of the readers of 

 your magazine. 



Ltgus limbatus. Fallen. 



Similar in shape to L. lucornm ; pale yellowish-green, densely clothed with pale 

 pubescence ; antennae dark, with the base of each joint narrowly pale ; a spot on 

 the liead in front, the base of the thorax, the scutellum, chiTus, a largo spot on the 

 end of the corium internally, dark brown ; scutellum lighter in the front angles, and 

 witli a small yellow spot at the apex. Extreme outer margin of corium and cuneus 

 black. Membrane dark, with the nerves and a spot below the apex of the cuneus 

 pale. Legs pale ; apices of femora bright red, with two deeper red rings ; tibiffi 

 with black spines, each springing from a black spot at its base ; apical joint of tarsi 

 black. Length 2 lines. 



The species varies to a pale uniform green, with the dark markings 

 scarcely distinguishable, but the bright red apices to the femora, and 

 the black spines springing from black spots on the tibiae, at once 

 separate it from any of its allies.
