Selandria Sixi, Voll. (Bouwstoffen voor eene Fauna van Neder- 

 land, iii, 278, 1858), according to Vollenhoven, is identical with S. 

 grandis, Zad., and, as it has priority by a year, the name of Sixi 

 must stand. The larva, according to the Dutch entomologist, feeds 

 on Poa aquatica. S. serva is not known in its earlier stages, but it 

 frequents the same marshy situations as Sixi. 



Poecilosoma longicorne, Thoms. (Hymen. Scand., i, 232, 6), I find 

 among my Scotch specimens. Mr. J. B. Bridgman has taken near 

 Norwich a Poecilosoma which seems to be intermediate between 

 longicorne and submuticum ; while I have from Rannoch an apparently 

 undescribed species. Without further specimens, however, I can say 

 nothing definite about them. The species mentioned at p. 119 of this 

 Magazine (vol. xvi) I have seen through the kindness of Mr. Roebuck. 

 It is a badly set specimen of excisum, Thoms.

DESCRIPTIONS OF FOUR NEW SPECIES OF RUSSIAN FSYLLID^. 



BY JOHN SCOTT. 



Some few months ago I wrote to M. .Takowleff at Astrachan, 

 asking him to be good enough to permit me to see all of the Russian 

 species of Psyllidce which he had in his collection, in order that I might 

 be able to give the localities of those already known to science, and, 

 further, to describe such as might prove to be new, in my monograph 

 of the PsyllidcB of Europe, on which I am at present engaged. I 

 received a box from him in September last, and I think it will be of 

 interest to give a list of the species forwarded to me. These are as 

 follows : 



Aphalara JaJcoicleffi, Scott, described in Ent. Mo. Mag., p. 266, 

 May, 1879. I am now able to say that this species is found on 

 Tamarix laxa, in May. 



Aphalara lurida, n. sp. A. hicolor, n. sp. A. unicolor, n. sp. 



Rhinocola tamaricis, Puton. Found upon Tamarix laxa in May. 



Alloeoneura radiata, Forst. 



Psylla glycyrrhizcB, Becker. P. spireece, Becker, taken at Sarepta. 



Trioza dichroa, Scott, described in Ent. Mo. Mag., p. 265, May, 

 1879. T. Dalei, Scott ?, immature example, found on Atriplex laci- 

 niata in May. T. elasagni, n. sp. 



Aphalaea lueida. 

 Green. Head scarcely as long as broad. Crotvn with a deep fovea on each side, 

 posterior margin slightly concave. Face : anterior margin somewhat deeply cleft 

 in the middle, lobes distinctly rounded. (Antennta wanting.)
