tions. It is therefore only in a few cases, \ think, that there is reason 

 to change the common names according to Horvath's observations. 



CYDNINA. 



1. Cydnus flavicornis, Fabr., = Mthus, id. 



2. [Brachypelta, Am. et Serv.,not British, = Cydnus, Fabr Type : C. tristis, 

 F., = Cimex aterrimus, Forst., 1771, Syst. Rhyng., 1803, p. 185, 7. 



Later authors, with I lie exception of Dallas, Sta.1, myself, and Kirkaldy, do 

 not seem to have duly observed that Fabricius, in Entomologia Systematica (1794), 

 as well as in Systema Rhyngotorum (1803), plainly marks out certain species as 

 genotypes by adding to the diagnosis the generic characters. This I have already 

 expressly pointed out in my Rev. Synon., p. 269. Puton therefore uses Cydnus, F., 

 quite wrongly for flavicornis, and still more incorrectly quotes Cydnus, Fall., under 

 Brachypelta as a synonym ; the genus Brachypelta does not exist, at all in Sweden, 

 and Fallen's generic name does not bear any relation to this species, but to Sehirus 

 morio, L., under which Cydnus tristis, F., has been incorrectly quoted.] 



PENTATOMINA. 



3. Sciocoris cursitans, F., is maintained by Oshanin for terreus, Schr. Puton 

 probably disapproved of the name, because the species had been described as a 

 Naucoris (!), but then consistency required that he should have disapproved also of 

 the name llallicus apterus, L., as that species was described as a Cicada ! 



4. Neottiylossa inflexa, Wolff, 1806, = pusilla, Gmel., 1789. The change lias 

 been accepted by Oshanin and is indisputably correct. 



ASOPINA (=CIMICINA). 



5. Picromerus, A. ct S. (= Cimcx, L., F., 1803). Kirkaldy has (Entomol., 

 1905, p. 76, seqq.) shown that the type of the Linnean Cimex could never be lectu- 

 larius, as (I) Linnaeus fixed no types, (2) Jectularius does not agree with the 

 diagnosis of Cimex, and (3) another type for the latter genus was duly selected by 

 Fabricius later on, who deliberately fixed on bidens as the type of Cimex. 



ACANTHOSOMINA. 



6. Acanthosoma denfatum, de Geer — Elasmosfethus inter stinctus, L. The 

 genus Elasmosfethus, Fieb. (part.), Stal (Gen. Pent., p. 39), differs well from 

 Acanthosoma (Type : hsemorrhoidale, L.), and possesses like this one several species. 

 (See Oshanin, /. c, p. 168). 



7. Acanthosoma interstinctum, Reut., = Elasmucha grisea, L. See Horvath, 

 Rev. d'Ent., 1898, p. 276. Oshanin uses for this species the generic name of Ch'no- 

 coris, Ilahn, Stal (Gen. Pent., p. 79), but as this name is due to our common bug 

 (see below), it ought to be replaced by Elasmucha, Stal (Ann. Soc. Ent. France, 

 1864, p. 54). The name Elasmostethus is to be accepted for interstinctus, L (den- 

 tatus, De Geer). 



8. Elasmostethus ferrugatus, F., = Elasmucha, id. 



COREINA. 



9. Enoplops scapha, F., = Coreits id., wns described by Fabricius, 1794, as a 

 type for the genus Coreus .'
