REMARKS ON SOME BRITISH HEMIPTERA-HETEROPTERA. 

 BY DR. O. M. REUTER. 



{Concluded from vol. xvi, page 175). 



In No. 157 (vol. xiv, p. 11) of this magazine, I began some 

 remarks on British Hemiptera-Heteroptera, which I will now finish. 

 I have only to make some corrections of my previous remarks, and to 

 reply to several objections made by Mr. Douglas to different points of 

 my observations. 



Pentatoma baccartjm, E. M. M., xiv, p. 11. Mr. Douglas's 

 remarks concerning the nomenclature of this species are quite correct, 

 and I am obliged for the elucidation he has given. However, I still 

 think -F '. fuscispina, Boh., is a good species, and different from nigri- 

 cornis, Eabr. 



Neides parallelus, /. c, p. 12. Mr. Douglas admits this species 

 to be only an imperfectly developed form of JST. tipularius, Linn. ; but 

 he says that it can hardly be termed brachypterous, " for it has fully 

 developed elytra, the wings only being short:" still, I think that the 

 term " brachypterous " may be employed in this case. The dimorphism 

 is here of the same kind that Dr. Sahlberg has named " crypto- 

 dimorphism " (Eeut., Ann. Soc. eut. de Er., ser. v, t. 5, p. 233), the 

 brachypterous form having the elytra only a little shorter, or, at least, 

 with narrower membrane, than the macropterous, bat the wings always 

 much shorter, and the pronotum posteriorly narrower and less convex. 

 The membrane in N. parallel 'us is not "fully developed," being much 

 narrower than in N. tipularius. 



Scolopostethus ericetorum, /. c, p. 13. Mr. Douglas thinks 

 this species is not decoratus, Hahn. This opinion has, however, not 

 been approved either by Dr. Puton or by Dr. Horvath ; and I also 

 must continue to hold my concurrent opinion. The figure 71 of Hahn 

 (Wanz. Ins., i, p. 139), can never be regarded as representing any 

 other species than ericetorum. All the legs are black, the antennae 

 black, with the exception only of the extreme lase of the second, and 

 the extreme apex of the first joint. These are just the characters of 

 ericetorum, which also often has the first joint of the antennae quite 

 black. The figure given by Hahn can nowise represent affinis, which 

 has the first joint of the antennae quite red, or only toward the base 

 black, and the second joint only in its apical half black, and the rest 

 red, or sometimes almost entirely red. In a finis only the anterior legs
