this last author (7. c). The true Capsus sordidus, Kirschb., is = 

 Macrocoleus tanaceti. Fall., Eeut., Saund., nee Fieb., nee Doug, and 

 Scott. Oncofj/lus imnctvpes^ Eeut. (= O. tanaceti, H.-Sch., Fieb., nee 

 Fall., nee Doug, and Sc.) is very different from the species with the 

 same name in the Catalogue of Douglas and Scott ; the former is a 

 true Oncotylus, and not found in Britain. 



PsALLUs. To my mind, and also according to Mr. Saunders, P. 

 alni and P. sanguineus (Cat., 41, 2 and 3) are only varieties of one 

 species (vide Rev. crit. Capsin., p. 17G). P. distinctus (Cat., 41, 9) 

 is likewise a variety of P. varians (Cat., 41, 8). I have seen per- 

 fectly different coloured varieties of P. dimimdus, representing a 

 different species, as well as P. distinctus. 



Neocoris Scotti (Cat., 42, 2) is only a variety of iV. nigrituhis, 

 Zett., as cited by Mr. Saunders (Synops., 301, 6). I have found it in 

 Finland in eopula with the typically coloured form. 



Capsus capillaeis (Cat., 43, 1). This is the sole Scandinavian 

 species which can be regarded as Cimex laniarius of the Systema Na- 

 turae, 726, 75 (described from Sweden). The diagnosis of Linne 

 accords vezy well with the var. danicus, Fabr. 



Camptobeochis punctulatus (Cat., 44, 1). The British species 

 of CamptohrocTiis is not punctiilatus of Fallen, but luteseens, Schill. 

 (= punctulatus, Fieb., nee Fall.), a species not yet found in Sweden. 

 I have examined several specimens communicated by Mr. Saunders. 

 The C. punetulatus, Fall., H.-Sch., Rent., Saund., is = C. FalJeni, 

 Fieb., erroneously cited by Messrs. Douglas and Scott as synonymical 

 with their species.

Pst/lla rhamnicola bred : description of the vymph. — Towards the end of last 

 month I paid a visit to Purlej Downs for the purpose, if possible, of learning some- 

 thing about the earlier stages of the above-naraed species. The large tree of Rhamnus 

 catharticus which grows in the valley, well known, I daresay, to many entomologists, 

 and where I took the original specimens of P. rhamnicola, was the first to which I 

 directed my steps, and after examining tlie leaves for some little time, I observed 

 first one and then another small creature running about upon them. I at once took 

 out my pocket-lens, and discovered they were the nymphs of some species of Psylla. 

 I then set to work to beat the branches into my sweeping net, and in a short time 

 had the satisfaction of collecting into a tin box a goodly number of these individuals. 

 On reaching home I turned them out into a wide-mouthed stoppered bottle, into
