Note on Li/cfus hrimneus found in London. — In the year 1862, on a small 

 log of wood with the bark on, imported into the London Docks from Swan 

 Eiver as a sample, I found five beetles, of a species which has recently been 

 identified as Lyctus briinneus by Dr. Sharp, who informs me that he has specimens 

 of it from New Zealand, France, and Britain, and that it is recorded from Woodlark 

 Island.— Id. : 10i!/i October, 187G. 



Note on Corixa vernicosa, Wallengr., and C. Douglasi CFieb.). — A renewed in- 

 vestigation of a typical example of Corixa vernicosa, kindly sent to me by Pastor 

 Wallengren, of Farhult, Sweden, and comparison therewith of specimens of C. 

 Douglasi, including several recently taken by Dr. Renter in Scotland, have convinced 

 me that both names refer to one species. The majority of the British individuals 

 diifer from the Scandinavian type before me in having the yellow lines on the corium 

 somewhat closer together, and the posterior lines shorter, thereby leaving the charac- 

 teristic black space at the inner angle larger. The synonymy will therefore be :

Notes on some additional species of PsyllidcB new to Britain.- — It is interesting 

 to find that this group still furnislies fresh representatives in different genera, and 

 as no doubt many others will be added, I at present merely give a list of the 

 additions. 



Psylla cratcegi, Scop., not common on hawthorn in August. P. costalis, Flor, 

 on hawthorn in August, in company with P. mali, from which it may be separated 

 by the green costal nerve and shorter elytra. P. stenolabis, Fr. Low, a single <J 

 beaten from an oak tree in this neighbourhood, was kindly named for me by th? 

 author, to whom I had sent it for identification. It is described by him in the 

 " Petites Nouvelles Entomologiques," for September 1st, 1876. P. j'yricola, Fiii-st., 

 taken by Mr. Douglas on pear trees in Scotland, not uncommon in August ; I have 

 previously considered this species to be only a variety of P. pyri, L., not having 

 before seen examples, and believing that tlie short diagnosis of Forster referred to it. 

 The elytra are shorter and yellower than in the last named, and witliout the black 

 marks between the nerves. P. pyrisuga, Forst. ?, and P. peregrina, Forat. ? : I have 

 as yet only females of these two, which Dr. Fr. Low agrees with mc in believing 

 may prove to be the species to which they are referred. 



I have also two other undetermined species of Psylla which are evidently new, 

 one of them allied to P. flaoopunclata, Flor. 



Trioza abdominalis, Flor. I have seen what I believe to be a c7 & ? of *his 

 species, taken by Dr. F. Buchanan White in Scotland on pjnes ; it js about the si7-e 

 of T. gain ; S black, with slu>rt yellowish elytra blunt at the apex, and with a green 

 abdomen ; ? orange-red, with paler longitudinal streaks on the mesonotum, abdomen 

 coloured as in the other sex : Flor appears to have seen only three males, the female 

 being unknown to him. T. abieticola, Forst. : this may be considered as good as a 

 new species, as Forster had only seen a single $ , sent to him by Mr. Walker when 

 he made liis description ; I have, however, met with it in gre.at abundance on Purley
