Thysanura. 
Japyx. A. Humbert discusses the characters of this genus 
and of the family Campodece, and reprints the Latin characters 
given of them and of Haliday’s Japyx solifugus by Meinert 
(Rev. et Mag. Zool. 1868, pp. 345-348). He figures the head, 
thorax, and the terminal segments of the abdomen (/. c. pi. 22. 
figs. 6, 7) of specimens from Savoy and Switzerland, which he 
refers to Japyx solifugus, and of which he gives a description, 
with comparative remarks upon the characters cited by Haliday 
and Meinert (/. c. p. 350). The author also indicates the differ- 
ences existing between the descriptions and figures of Haliday 
and Meinert, and seems inclined to regard those presented by 
the terminal forceps as of specific value. He also describes a 
new species, sent by Sumichrast from Mexico.
