He now gives the characters of the genus, and cites the following species as 
belonging to it: — C. aptera (Charp,), inch dilatata simplex (Lafr.) and 
alpina (Bon.) j C. dufouri (Serv.) j C. paupercula (G(Sne) j and C. aeantho- 
pygia (G^n^). Cheli{lura anthrmina (Kolen.) is the larva of F. higuttata 
(Fab.). 
Bourn also gives some additional characters of his Pygidicrana opldhaU 
mioa (/. 0 . p. 844), indicates some characters of SiSl’s F. parvicoUis (referred 
to Psalidophora), and fully describes F, ochropus (Stftl), which he places iu 
the genus Labia (/. c. p. 345). 
Stone ascribes the destruction of wasps partially to an abundance of ear- 
wigs, and Westwood thinks that they may also be injurious to bees. Proc. 
Ent. Soc. 1805, pp. 113-114. 
Weir & Westwood discuss the use of the caudal appendages in the ear- 
wigs. Proc. Ent. Soc. 1806, pp. 110-117. 
Perty (Mitth. naturf. Ges. in Bern, 1807, p. 309) notices an example of 
Forficula auricularia having the right half of the forceps cf , the left $ . 
Lucas has obtained a long yellow worm, probably a Mermis^ from specimens 
of Forjicula auricularia which had the abdomen much swelled. The worms 
issued between the first and second abdominal segments on the dorsal surface.

Goureau (Insectes nuisibles, pp. 60-64) describes the natm*al history of 
the species of this family, which inhabit houses in Europe, especially P. 
amei'icana and orientalis. He describes the general characters of P. germanicuy 
lividUy and lapponicay which, he says, live in our woods, but never iu the inte- 
rior of houses. This, however, is incorrect. 
Polyphaga mexicana (Burm.) occurs in the Mexican cave of Cacahuamilpo, 
according to Bilimek, Verh. zoql.-bot. Ges. in Wien, xvii. p. 904. 
O. Heer has published (Vierteljarsschr. naturf. Ges. in Zurich, ix. pp. 273- 
302) a list of the fossil species of this family, with descriptions of new species. 
Brunner von Wattenwyl (Nouveau systeme des Blattaires) 
divides this family into the following subfamilies : — 
I. Femora spinose. 
A. Last ventral segment in 5 ample, flat, with no subgenital lamina. 
1. Supraanal lamina very narrow, transverse j wings with a triangular 
apical field Ectobidjb.
