TlIE following Memoir contains descriptions of seventeen spn-ios of Thymnnrtt, 



belonging to the Smynthuridae, Poduridae, and Lipuridae. Five are new ; the others hav< 

 been already observed on the Continent. With those described in my previous Memoirs. 

 and the sixteen in that of Templeton, this will make a total of about fifty species, one- 

 fourth of which have been as yet observed in this country only. I have also met with 

 several forms which will probably prove to be distinct species, but about which 1 mid ttol 

 as yet prepared to offer a decided opinion. There can, however, be very little doubt that 

 many more species remain to be discovered in this country. Even the Continent haa 

 been anything but thoroughly examined; and yet, including the Lepismidas and tin 

 curious genera Campodea and Nicoletia, 117 species are said to occur in Europe, of which 

 eighty-three have been fonnd in Prance.

Green; eyes on a black patch; terminal segments of antennae reddish ; abdomen with 



a reentering angle ; hairs scattered. 

 Length tV of an inch. Very common among grass, in May, June, July, August, and 

 September. It is sometimes attacked by a small red mite. 

 Geoffroy's description of this insect is still quite sufficient : ? B. viridis, oculis 



capite flavescente, antennis in medio fractis." 



The antenna have the basal segments pale green, the terminal one re, hash. Th 

 segments increase in length from the base to the apex. The basal one is of an im-l, 

 in length, and -003 in breadth; the seeond is -008 in length, the thud 013, and he 

 fourth 027. The segments do not taper, though eaeh i. .little narrow,, ,a,, , to
