Bagous diglyptus, Boh. (a species new to the British list), at Burton-on- Trent. — 

 Two examples ( ^ and ? ) of a Bagous, recently submitted to me for inspection by 

 my friend, Mr. J. T. Harris, I find on examination to be B. diglyptus, Bob., a spe- 

 cies not hitherto recorded as British. Superficially, not unlike B. brevis, Schon., 

 diglyptus may be at once separated from that species by its proportionately shorter 

 and broader form, the thorax not having three fovete just before the apex, the much 

 shorter tarsal joints, &c. ; from lutulosus, Gyll., which it resembles in its very short 

 stout tarsi, it may be known by its larger size, stouter limbs, the alternate interstices 

 of the elytra less raised, &c. 



The very short broad form, uniform grey colour, the head longitudinally im- 

 pressed between the eyes, the rugulose thorax, which is much consti'icted before the 

 apex, and having a short dorsal channel near the base, the alternate interstices of the 

 elytra slightly widened and raised, with the usual callus on the 5th almost obsolete, 

 the very short stout limbs, the tibiae ferruginous, much curved inwardly and thickened 

 above the middle, and the very short tarsi with the penultimate joint simple and not 

 bilobed, readily distinguish this species from its allies. 



M. Chas. Brisout de Barneville has corroborated this species for me, and remarks 

 that it is still very rare on the continent. One example, taken by Mr. Hai'ris from 

 accumulated flood-refuse in his own garden on the banks of the Trent, at Burton, in 

 April, 1872, and a second subsequently found by Mi's. Harris crawling on a wall near 

 the same spot. — Gteo. C. Champion, 274, Walworth Eoad, London, S.E. : January

Synonymic notes on some British Semiptera. — In Dr. Puton's recently published 

 "Synopsis des Hemipteres-Heteropteres de France" (vide p. 94, ante), there are some 

 points which, having reference to British species, deserve our special attention. 



Nysius maculatus, Fieb., is reckoned to be only a variety of N. thymi, Wolff, 

 but Dr. Puton says he has not Fieber's types. 



Nysius brunneus, Fieb., is referred to N. helveticus, H.-Schf., as a variety ; and 

 N. obsoletus Fieb., and N. ericce, Boh., are put as synonyms of helveticus. 



KiEiDOCEETJS, Westw., is substituted for Ischnorhynchus, Fieb., but I cannot 

 find that Westwood ever characterized a genus under that name. In Stephens's 

 "Catalogue of British Insects," ii, 342 (1829), the name first appeared as " Kleidocerys, 

 Westw., MSS.," and in his " Introduction to the Modern Classification of Insects," 

 ii, Synops. 123 (1840), Westwood puts it as a synonym of Cymiis, Halm ; being, there- 

 fore, merely a name, it cannot supersede Ischnorhynchus, which is a genus duly 

 defined by Fieber. 



The species reseda, Panz. (F. Gr., 40, 20), is made to give way to d'ldymus, Zett. 

 (Act. Holm., 1819), but, according to Hagen, Panzer's description and figure were 

 published in 1797, and his name must, therefore, be adopted. 



Heteeogastee, Schill., was superseded by Phygadicus, Fieb. (Eur. Hem., 201), 

 expressly on account of the previous employment of the name in Coleoptera by 

 Dejean. 



Stygntts, Fieb. The name having been already used by Laporte in Arachnida, 

 was altered to Sttgnocoeis in Brit. Hem., p. 213. 



Pachtmbeus. When, in 1875 (Ent. Mo. Mag., xi, 185), I i-epeated what had 

 been already said by others, that the names Pachtmeetjs, Le Pel. et Scrv., and
