2 RHYNCHOPHORA. 
Editors from Mexico, whence two species have been recorded, and this habitat therefore 
requires corroboration. Lacordaire includes the genus amongst the ‘‘ Naupactides, 
most of which belong to the Otiorrhynchine.

Hab. Nortu America ! ?,—MExico °. 
If this insect is really nothing more than a variety of the European S. flavescens, 
Marsh., as stated by Allard (doc. cit.), it has no doubt been introduced into Mexico, as 
well as into the United States. 
2. Sitones ordinarius.

I have seen one of the types of this species, which, as Allard states, is very like the 
European 8. puncticollis, Kirby, but differs from it in having the head sharply sulcate 
between the eyes, the prothorax a little more rounded at the sides, and the fifth elytral 
interstice callose towards the apex. 
Group HYPERINA. 
Hypérides, Lacordaire ; Phytonomini, Leconte & Horn (part.) ; Hyperini, Bedel, Petri. 
This group contains but few representatives in Tropical America, and these mostly 
belonging to the genera Isorrhinus and Phelypera.  Listronotus, Jekel (a genus 
represented in Mexico, and extremely closely allied to Desiantha, Pase., of Australia), 
referred to the Hyperina by Leconte and Horn, seems to me to be more nearly related 
to the Erirrhina. 
HYPERA. 
Hypera, Germar, Mag. Ent. iv. p. 335 (part.) (1821); Capiomont, Ann. Soc. Ent. Fr. 1867, p. 490; 
Petri, Monogr. Hyperini, pp. 6, 25 (1901). 
- This genus, even if Phytonomus is retained as distinct, includes numerous represen 
tatives, most of which inhabit the Palearctic region. The single species now added 
from the mountains of Western Mexico is a very remarkable form *. 
* In the Sallé collection there is a specimen of Phytonomus rumicis (Linn.) labelled as from “ Mexico,” but 
further evidence is required before it can be admitted into our list. 
P. rumicis (?=diversus, Gyll., and 
comptus, Say) has, however, been recorded from North America.
