apex of the clavus ie a silvery-white band terminating at the claval suture, and 

 at about one-tliird the distance from the apex is another similar one, slightly 

 angulato (in cinnamopterus it is slightly convex), continued across the clavus. 

 Membi-ane brown, velvety, with a broad iridescent margin along the margin of 

 the cuneus narrowly white. Prosternum black ; posterior margin of the meso- 

 sternum, on the sides, silvery- white. Legs brown ; coxce and fulcra white or 

 pale yellowish-white ; thighs brown ; 3rd pair darkest ; base and lower margin 

 at the apex frequently reddish-brown ; tibi(B ferruginous ; tarsi white or pale 

 yellowish-white ; 3rd joint dark brown. 

 Abdomen, underneath, black, with a broad silvery-white band extending from the 

 2nd segment to the posterior margin of the 6th, slanting inwardly in the 

 direction of the apex. Length, 1| line. 



In colour and size, this species mostly resembles P. cJavafus, but 

 differs from it in tlie following characters : — the more contracted 

 anterior margin of the elytra, the continuous nearly straight lower 

 silvery band on the same, and a simple silvery spot at the inner basal 

 angle of the cuneus, as in P. cinnamopterus, from which species it may 

 also be distinguished by the different colouring of the antennae, elytra, 

 and tarsi. 



With us, this is the commonest of the three British species. It 

 occurs in July and August, on oak trees in a hawthorn hedge, as well 

 as in the hedge itself, in the vicinity of the nests of Formica rufa, in 

 company with which insect we believe it dwells. 



Camaronotus ciniiamoptvrus, Fieb., Doug, and Scott, Brit. Hem., i, 

 359, 1, is not, as stated by Renter in his " Revisio critica Capsiuarum," 

 part ii, 8.5, 1, tlie Cimex hlfasciaius, Fab., Mantiss., ii, 305, 264. Stal 

 confirms Fieber's view, and refers the insect to the genus Closlerotoimis 

 of this author.

ON THE LAEVA, &c., OF CATACLYSTA LEMNALIS. 

 BY WILLIAM BUCKLEB. 



On TsTovembcr 10th, 1874, Mr. "W. C. Boyd kindly sent me 

 six young larv» of this species in their cases, and I found no great 

 difficulty in keeping them in thriving condition by placing them in a 

 vessel of water with a sup[)ly of Lemna minor floating on the top. It 

 gave me much interest and pleasure to watch them from time to time, 

 and I have set down my observations as it occurred to me to note them. 



AVhen they first arrived, these larvso were often protruding from 

 their cases half or more of their bodies, both on the surface of the 

 water and also below it, while appai-ently examining the surrounding
