 Trans. 1, 425. 

 The head and prouotum of dried sjjeciraens turn yellow, and the 

 hemelytra ouly^preserve the delicate green colour of the living insect. 

 Found locally in great profusion in damp meadows, but only in certain 

 years. Very numerous in 1864 in Leicestershire, on the banks of the 

 Soare. Less frequent on Wimbledon Common in 1865. 



Note. — To this section belongs, perhaps, lasstts cMorizans, Hardy 

 M.S., a fine species from Scotland, examples of which, presented by Mr. 

 Hardy, are in the British Museum. I have had no opportunity of 

 examining this insect, and have not succeeded in procuring any infor- 

 mation about it. It appears from a hasty inspection to be about 2^ 

 lines long ; the head and pronotum are j^ellow, and the hemelytra pale 

 green. See Walker's Cat. of Brit. Mus. Homopt. No. 100 (lassus), 

 where I. assimilis Ahr. For. 17, 15 is given as a synonym. The latter, 

 however, is Pediopsis virescens, as plainly appears from the fig. in Ahrens 

 Fn., 1. c, as well as from the words " Vertice brevissimo,'' applicable 

 only to a Byihoscopus or Pediopsis. To increase the confusion, there 

 is an insect described as Cicada assimilis by Fallen, Kongl. Vet. Ac. 

 nya Handl., 1806. p. 22, and Hemipt., part 2, p. 35, which is certainly 

 a DeltocepJialv^, and is wrongly quoted by Ahrens as identical with his 

 lassus (Pediopsis) assimilis. See also Flor, R. L. vol' 2, p. 253 (Z 

 assimilis). I conclude only from these descriptions that the Scotch 

 species in question is not assimilis Ahr., nor yet assimilis Fall., Flor,
