Not represented in the British Museum. 
It is quite probable that this speeies (described from 
Australia) does not belong to Choroedocus at all, but I 
still think it useful to include it here provisionally. 
The three species of Choroedocus, known to me from 
specimens, may be easily distinguished by the aid of the 
following key :— 
1. (4) General coloration yellowish-grey. Elytra with brown spots 
or points. Wings slightly infumated towards the fore 
margin and apex. Hind tibiae dull sanguineous or 
yellowish. 
2. (3) Elytra with numerous rather large brown spots. Male sub- 
genital plate truncate at the apex. . . capensis Thunb. 
3. (2) Elytra with-few small black spots and points. Male sub- 
genital plate conical. . . . . . . tllustris Walk. 
4. (1) General coloration greenish-brown. Elytra without any : 
brown markings. Wings strongly infumated except inner 
margin. Hind tibiae coral-red. . ..» . robustus Serv. 
Genus EuPpREPOCNEMIS Fieber. 
I. Bolivar only included five species in this well-charac- 
terised genus, but my study of the British Museum col- 
lection has doubled this number, while I am able to 
describe a series of new species and forms, as well as to 
establish the correct synonymy of some others, hitherto 
little known. I give, therefore, a full list of the species 
of this genus, though some of them are not represented 
in the Museum collection. 
1. Euprepoenemis plorans (Charp.). 
The synonymy of this species given by Kirby (Syn. Cat. 
Orth., i, p. 560, no. 1) is quite correct, except in the case - 
of #. plorans var. intermedia Bol. (= EH. alacris Serv., see | 
below). I would add, however, the following synonyms :— 
1846. Calliptamus reticulatus Fischer Waldheim, Orth. 
Imp. Ross., p. 239, tab. xix, fig. 1 (see Uvarov, Horae 
Soc. Ent. Ross., xl (3), p. 35).
