In the "Wiener cntomologiecho Monatschrift," viii, 215, 14 (1864), Fieber 

 described Trapczovotus distinrAuii, D. and S., and T. distinguendus, Flor, as distinct 

 species, but both as liaving the tliird joint of the antenna; red in the middle (GUed 

 3 rostrothlich, am Grund und Endc schwarz). This is vemnvkable, for he says he 

 had the original example of distiiiguendus fi-ora Dr. Flor for inspection. 



In the " Stettincr ent. Zcit.,' xix, 181, 23 (1858), Dr. Stal described Tlhiparo- 

 chrnmus convivm as "articulis 2° ct 3° antennarum medio late flavescentibus." In 

 the " Ofv. k. Vct.-Ak. Forhandlingar," p. 55 (1872), he repeats this, placing the 

 species under the cenns Trapezonotus, and adds, as a separate species, T. distinguendus, 

 Kor, but describing the antenna; as " articulo tertin pallide annulate." 



In his " Opuscula Entomologica," ii, 192, 28 (1870), Thomson has Lygceus 

 convv-us, Stul, = distinguendini, Flor ; but he says of the antenna; " articulo tcrtio fere 

 toto rufo," which is not correct for either. 



According to descriptions, there arc four allied species of Trapezonotus : — 



1. distinguendus, Flor, nee auct. (= convivus, Stal, sec. Thorns.). 



2. distinguendus, Fieb., Stiil, Saund., nee Flor. 



3. distinctus, D. and S., Fieb. {= distingiiendiis, Flor, sec. Saund.). 



4. convivus, Stiil, nee Thorns. 



The question therefore to be decided is whether the above-named are really four 

 species or only forms of one, and I commend it to the attention of those hcmipterists 

 who haye access to type-examples. — J. W. Douglas, Lee : lith October, 1875. 



Notes on some species of Corixa. — In the " Ofversigt af K. Vet. Ak. Forhand- 

 lingar," 1854, Pastor Wallengren described as new four species of Corixa under the 

 names of Fieheri, vaga, variegata, and vernicosa. Several months ago, the worthy 

 Pastor sent an example of each for my inspection, and I having returned them to 

 him by the hands of Dr. John Sahlberg, the latter writes that he quite agrees with my 

 determinations, which are as follows: — C Fieberi and C. vaga = C. hieroglyphica, 

 Duf. ; C. vanegata= C. intricata, D. and S., which latter name will bo superseded ; 

 C. vernicosa is a distinct species alUed to C. Linnei, Fieb., but not yet detected in 

 Britain. 



In the "Notiser nr Siillsk. pro Fauna et Floi-a Fennica Forhandlingar," t. xiv 

 (1875), Dr. J. Sahlberg has a monograph of the Finnish Corixre, which is of interest 

 to us, especially with regard to the British species. 



C. sodalis, D. and S., is admitted to be a good species, but C. socio, D. and S., 

 is put as var. b of C. prcetista, Fieb. ; it appears to me, however, that the differences 

 of marking on the elytra and tarsi are sufficient to give it rank ns a species in default 

 of absolute proof to the contrary. 



C. nigrolineata, Fieb., is reckoned as = C. Fahricii, I'ieb., but I look upon this 

 as very doubtful. C. decora and C. diibia, D. and S., are supposed to be varieties of 

 the species thus constituted ; but I now look upon C. decora, of which I Iiave only 

 the single original example, as an immatvtre C. perplexa, D. and S., to wliicli I also 

 refer the subsequently described G. Whilei, D. and S., all of which have the marginal 

 channel of the elytra pale ; and C. dubia may be regarded as a form of C. nigrolineata. 

 C. Sharpi, D. and S., is identified as =r C. cognnta, Fieb., and the still older 

 C. carinata, Saldb. 



Two new species are described, which not iinpri)l):il)ly may be found in North
