COLEOPTERA. 407 
In this elaborate memoir the author discusses the structure 
of the skeleton of the thorax and head in the Coleoptera, and 
refers in detail to the opinions of previous writers on the sub- 
ject. His conclusion is opposed to the conception of an analogy 
between the segments of an insect and ihe vertebrae of the 
higher anitnals. He regards the head as composed of a single 
segment, and the organs of the mouth as its metamorphosed 
pleurae,

This is an enlargement of the paper on the structure of the 
luminous organs in Ldmpyris splendidula^ published by the 
author in 1864, and referred to iu the Record for that year at

curious structures described by the author. 
General Notes. 
Dietrich, in his Catalogue of the Coleoptera of Zurich 
(Nouv. Memoires Soc. Helv. Sci. Nat. tom. xxi. 1865), enume- 
rates 1872 species as occurring in that canton, or about the half 
of the species known from the whole of Switzerland. Referring 
to FuSsli^s catalogue published in 1775, and which includes 1203 
species, the author remarks that since the date of its publication 
several species appear to have disappeared from the eanton of 
Zurich, Fiissli includes Ulomd cvlinaris in his catalogue j but 
it is no longer to be found in Zurich. Very few species of 
Aphodius occur there, and Copris lunaris and the species of 
Onthophagm haVe either disappeared or become very scarce. 
This diminution in the number of Dung-beetles is attributed by 
Dietrich to the prevalence of the practice of feeding cattle in 
stalls. A few species appear to have immigrated into the can- 
ton since Fiissli^s time. The author enumerates the families and 
their constituent genera and species in a table. All the Euro- 
pean families admitted by Schaum, except nine, are represented 
in Zurich ; these nine families are small and chiefly confined to 
the south of Europe. The largest families are Staphylmidm with 
354y Curculionid^e with 304, Carabid(B with 182, and Chrysonte- 
lidce {—Fliyiophagd) with 181 species. The genus Apion is 
represented by 58 species ; the genera Stenus, PhilonthuSj Ho- 
malota, Cantharis (= Telephorus) , Siudi Bembidium comQ next in 
number of species. OtiorhyncJius, the most extensive European 
genus of Coleoptera, includes only 14 species found in Zurich. 
Desbrochers des Loges gives a list of Coleoptera captured by him in 
France and not included in Grenier’s catalogue, namely Ptindla pallida
