This species belongs, as may be easily recoo-uised by the widely 

 dilated sides of the pvouotuin, to the group which includes Clinocoris 

 lectularius, L. It differs from that insect by its smaller size, by the 

 body being clothed with longer hairs and provided with less dense 

 punctuation, the very narrowly l)ut distinctly reflexed margins of the 

 pronotum, the shorter and darker scutellum, the more thickened legs, 

 and especially by the different shape of the elytra. The rudimentary 

 eMra have the commissural (inner) margin straight and longer than 

 the scutellum ; their apical margin is nearly straight, but much 

 rounded towards the exterior angles. The pronotum is less emargi- 

 nated at the apex and its marginal cilia are longer than the breadth of 

 the insect's eye.

CHLORIONA DORS AT A. Edw., AN ADDITION TO THE LIST OF 

 BRITISH HOMOPTERA. 



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



Three species of Chloriona have hitherto been recognised as 

 British. I am now able to add a fourth, viz., C. dormfa, Edw., of 

 which I have taken both sexes in some numbers in Eppiiig Forest. 

 Like the other members of the genus, it lives on reeds, and so far as 

 my present experience goes, it occurs only at one pond. Mr. Edwards' 

 description of the ^ , taken from two specimens from " Haute Savoie," 

 is given in Ent. Mo. Mag., xxxiv, p. 59, and I reproduce it below for 

 convenience of reference. At the time the description was made, the 

 ? was not known. I have therefore added a description of it. Usually 

 the ? ? of this genus are difficult to distinguish from one another, 

 but that of C. dorsata may readily be recognised by the dark ring at 

 the extremity of the abdomen, which does not occur in either of our 

 other British species. The description of the macropterous ? is taken 

 from the only specimen I possess.
