G. ptisilla is usually a little smaller than calmariensis, it is less 

 marked with black on the upper-side, and the colour of the upper- 

 surface is a little paler. It is most easily distinguished by the ter- 

 minal two segments of the abdomen being entirely red. 



Bedel (Faune Col. Bassin Seine, v, p. 279, note) declines to accept 

 pnsiUa as a valid species; but it is still maintained in the recent 

 European catalogue, and I incline to the opinion that it is valid. 



The species occurs in this country both in spring and autunm. 

 My localities for it are Horning, Mildenhall and the New Forest.*

CYBTORRHINUS GEMINUS, Flor, AN ADDITION TO THE LIST 



OF BKITISH HEMIPTEBA. 



BY E. A. BUTLER, B.A., B.Sc, F.B.S. 



Of the genus Cyrtorrhimis four species are known to inhabit 

 Europe, and three of these have long been recognised as British. The 

 fourth species, C. cjeminus, Flor, which has hitherto been recorded 

 only from Scandinavia, Finland, and Livonia, may now be added to 

 our list. I have in my collection two British specimens ; one of these 

 was taken at Broxbourne last September, the other, which has hitherto 

 been standing unrecognised in my long series of G. pygmseus, Zett., 

 was taken many years ago somewhere in the South of England, 

 probably in Surrey, but unfortmiately I have no record of the exact 

 locality. 



0. geminns is so much like C. pygmsens that only the differences 

 need to be pointed out. In C. geminus, the basal joint of the antennae 

 is considerably longer than in C. pygmmus, and instead of being black 

 with pale apex, as is always the case in C. pygmasus, it is either wholly 

 pale, or with at most a slight dark shade at the apex; the legs of C. 

 gemmus are much longer, and the spines on the hmd tibiae larger and 

 darker. The insect as a whole also is sHghtly larger. The size and 

 colour of the basal antennal joint will, however, always enable it to be 

 recognised. In habits it resembles C. pygmaeus, being found in damp 

 places low down amongst rushes.
