as new, I name it after the food plant, D. epiJohii* It is also this 

 species, wliicli in the Ent. Mo. Mag., a'oI. xvii, p. 166, is quoted under 

 the name D. stacJii/dis, Rent., according to specimens found by Saunders 

 at Hastings, and wrongly determined by me as my stachi/dis, from 

 which it is easily distinguished amongst other characters by the longer 

 first joint of the antennae. 



As D. jjnlUdus I have quoted (Ent. Mo. Mag., vol. xiv, p. 186) a 

 species found at Perth on Si/mplnjtuni, still this species is not the true 

 pnllidus, H.-Sch., neither is it identical with my new species fjniohii, 

 but it agrees thoroughly with the ty^pical specimens of D. constrictus, 

 Boh., a species referred without reason by Fieber as a synonym of 

 2)aUidus. 



A very different species has been confounded with D. errans, 

 AN'olff. Messrs. Douglas and Scott say (/. c. p. 3S0), " frequently the 

 ? has undeveloped elytra." Also concerning pallidus, it is said, " ? 

 with undeveloped elytra without cuneus (!) and membrane." All the 

 females of epiJohii (^ paJIidns, D. & S.) which I have seen, however, 

 have, like the female of errans, completely develoj)ed wings. Perhaps 

 the paler specimens of the species, with undeveloped wings, confounded 

 with errans, have been supposed to be $ of pallidus, D. & S., the 

 darker specimens being described as $ of errans. But the $ of errans 

 is always macropterous, as far as I know, and I have examined a great 

 many from different parts of the palearctic zone. The species which 

 has been regarded as being a short-winged ? of errans is, however, in 

 both sexes dimorphous, and easily distinguished by the short first 

 joint of the antennte, this character allying it to paUicornis, Eieb. It 

 lives on SfacJii/s sylvaticn, and is widely distributed in Europe ; it is 

 also found in the west of Siberia. I have named it D. stachijdis, by 

 which name it has alread}" been recorded from Britain by Mr. Norman 

 (Ent. Mo. Mag., vol. xv, p. 255), by the same author (J. c. vol. xiv, p. 

 166) given in error as D. errans. This species is also described by 

 Eior (Rh. Livl., i, p. 483) as coUaris, Fall., and by me (Hem. Gymn. 

 So. et Fenn., p. 128) as the brachypterous form of errans. 



I am publishing in the third volume of Hemipt. Gymnor. Europse 

 (now in the press) the more detailed descriptions of the European 

 species of Dicyphiis, and I shall there give a complete account of their 

 synonymy. As the British fauna, however, now possesses seven 

 species instead of five, and as it is not impossible that two other ad- 

 ditional species {pallidus, H.-Sch., and lujalinipennis, Klug) may yet 



* Mr. S.iunders has written to me (Dec. 2nd, 1882'—" I have seen a pair of pallidus which 

 Mr. Douglas has lent me ; they are clearly identical with the pale Ei^ilobizon form."
