THERATES. 
Having given a list of the species (Berl. Zeitschr. 1860) and a 
supplementary note to it (¢b¢d. 1862), I will confine myself here to 
a few observations. 
Therates vigilax, Schaum, from the Philippine Islands, varies in 
the extent of the black colour of the elytra; I have seen specimens 
where it has even completely disappeared and the elytra are quite 
yellow. The same variation seems to occur in Th. fasciatus from 
Celebes; for a specimen in Mr. Wallace’s collection with entirely 
yellow elytra did not, on a cursory examination, appear to me to be 
anything but a variety. Th. flavilabris, Fabr., seems to have been 
established on such a specimen ; his type was considered as a variety 
of fasciatus (Boisd. Faun. de ’Océan. p. 10) by Latreille. 
To the list of species enumerated by me is to be added T'h. cyaneus, 
Chaud. (Bull. d. Mosc. 1861, iv.), from Mysol. 
The name of the species no. 3 of my list (Berl. Zeitschr. 1860, 
p. 183) ought to be cwruleus instead of cyaneus. 
VII.— Descriptions of four new Genera of Carabidee. 
By Dr. H. Scnavm. 
Tyzonorus [tribum novum 7'ylonotint constituens |. 
Coxe medi@ valde approximatie, mesosterno et metasterno apice angustis. 
Epimera mesothoracis episternis concreta coxas medias attingentia. 
Tibie antice simplices, anteriores intus ciliatee. 
Prothorax dorso turbinatus. 
Margo elytrorum integer. 
This most interesting insect, on which I propose to establish a new 
tribe of Carabide, bears a great similarity to the Ozenid (espe- 
cially to the genus Z’ropopsis, Sol.), and agrees with them (and the 
Pseudomorphide) in having a very narrow mesosternum, so that the 
middle coxe are nearly contiguous ; it differs, however, by its com- 
pletely simple anterior tibis, by the margin of the elytra not being 
interrupted, and by the epimera and episterna of the mesothorax 
being entirely connate. 
Hyes prominent, entirely globose, not truncated or emarginated behind
