Platypsyllidjd. 
Platypsylla. Leconte, P. Z. S. 1872, pp. 799-804, pi. Ixviii., describes the 
single known species very minutely, in all the salient features of its external 
anatomy. He considers it should form the type of a family, Platypsyllidee, 
which he places in the Coleoptera, between the HydrophilidcB and a family 
Leptinidce (erected by himself in 1866 for the reception of Leptinus), but 
vnth. a strong tendency to the Trichopterygidce and Corylophidce. Various 
portions of the insect are figured. The author repeats this opinion in P. E. 
Soc. 1872, p. xxviii, considering P. castoris to be rather an inquiline than a 
true parasite, living probably on epidermal scales. Westwood, ibid.) demurs 
to the insect being considered Coleopterous.

European Russia. Nachr. Ges. Mosc. (1872). Translated 
into the Russian language from the Recorder's MS., with 
Latin diagnoses of some new spp. 
Consists 'chiefly of notes on a collection of Russian Neuroptera. An ex- 
tract, under the title 'Notes sur quelques especes de Phryganides, et sur une 
Chrysopa,^ appears (in French) in Bull. Mosc. 1872, pt. 3, pp. 187-194.

The Odonata are by De Selys, the Non-Odonata by the Recorder. They 
enumerate about 110 spp. as now known from Asia north of the parallel of 
50° of latitude. Of these 43 are Odonata and 67 Non-Odonata. 77 also occur 
within the limits of Europe, and 49 in the British Isles. The aspect of the 
fauna is decidedly European, with occasional North American and Exotic 
elements. 
In Ann. Sc. G(5ol. ii. is a memoir by Oustalet (see antb) p. 224) on the 
fossil insects of the tertiary formations of France, in which a larva is de- 
w,ribod and figur<'d as Lihellida minuscida ; the impression of a wing as 
Ancalaphm cdwardni (which the Recorder thinks wuw no Ascalaphus), and
