is double-brooded, and that the larva lives upon sloe and sallow, but, 

 in Vlind. Ned. Micr.,508 (1882), Snellen contends that it feeds "only 

 on sallow (Salix alba), and not on sloe (Prunus spinosa) as Treitsohke 

 says." I have failed to find any confirmation of Kollar's belief that 

 the species produces two broods in the course of the year.

NOTOCHILVS HAMULATUS, Thoms., AN ADDITION TO THE 

 LIST OF BRITISH HEMIPTEUA. 



BY EDWARD SAUNDERS, F.R.S., &c. 



This species, which closely resembles the common Notochilus con- 

 tractus, H.-S., has probably been overlooked b\ r most collectors, and 

 it will probably be found not uncommonly when it is looked for. I 

 have seen several specimens from this country. Mr. Champion has 

 found two in his collection labelled "London district," one of which he 

 has very kindly given to me. Mr. E. A. Butler has also two speci- 

 mens, but without notes of locality, one of these, however, came from 

 Dr. Capron's collection, and so was probably from the neighbourhood 

 of Shiere in Surrey. Mr. West of Lewisham has one taken in rubbish 

 at Lewisham ; he took two specimens in the same spot which he sent 

 to me for examination, they are both of the small size and dark colour 

 of hamulatus, but one of them has all the other characters of con- 

 tractus, and I feel convinced is only a small dark variety of it. 



N. hamulatus may be known by its smaller size, its rather shorter 

 and therefore thicker looking antenna?, itg shorter pronotum, which 

 is less widened posteriorly (N.B. — both species are macropterous), 

 and rather more closely and more rugosely punctured, its transverse 

 impression rather less strongly marked. The elytra are rather darker, 

 especially at the base, and the spot near the apex is reduced to a 

 minimum, the corium also is less punctured. 



I bring this forward as it is generally recognised on the Continent 

 as a distinct species ; but I must say I think that the characters which 

 distinguish it from contractus are unusually " slender."
