226 PHYTOPHAGA.—SUPPLEMENT. 
closely punctured than the thorax, the interstices (especially at the sides) finely transversely rugose, the 
shoulders smooth and prominent; underside nearly black, very finely punctured; legs fulvous, sparingly 
pubescent, the apices of the anterior tibiz produced into a strong tooth. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith, Hoge). 
In the robust antenne in the male, the shape of the thorax and its sinuate margin, 
&c., this species agrees well with Aletes. The female insect has the antenne shorter 
and scarcely thickened. The upperside is very slightly metallic. 
6. Alethaxius pubicollis. 
Blackish-green, the basal joints of the antenne and the femora obscure fulvous; head and thorax geneous, the 
latter closely punctured and sparingly pubescent ; elytra metallic greenish, strongly punctured, the sides 
transversely rugose. 
Length 14 line. 
Elongate, parallel; the head rather remotely impressed with oblong punctures, eneous ; the clypeus transverse, 
defiexed ; labrum piceous; antenne robust, two-thirds the length of the body, black, the lower four joints 
more or less fulvous ; thorax more than twice as broad as long, the sides strongly rounded, very obscurely 
angulate at the middle, the surface crowded with small punctures (especially at the sides), sneous, laterally 
clothed with fine short whitish pubescence ; elytra with a very obsolete depression below the base, greenish, 
the punctuation much deeper than that of the thorax, and obsoletely arranged in rows, the interstices at 
the sides strongly transversely rugose ; legs robust; the underside and tibie nearly black. 
Hab. Mexico, Chilpancingo (H. H. Smith). 
A single specimen only of this small species was obtained. It is well distinguished 
by the sparingly pubescent thorax and its general colour. 
RHABDOPHORUS (p. 148). 
Rhabdophorus, Lefévre, Mitth. Miinch. ent. Ver. 1878, p. 126 (nomen preocc.). 
Rhabdopterus, Lefévre, Cat. Eumolp. in Mém. Soc. Roy. Liége, xi. p. 46 (1885). 
For this genus Lefévre has proposed a change of name, the one first used by him 
being preoccupied. 
Rhabdopterus salvini (p. 148). 
&. salvini and R. rugosus (antéa, p. 150), as already noted on p. 217 of this Supple- 
ment, have been transferred to Talurus by Lefévre. 
Rhabdopterus jansoni (p. 149). 
Fo the locality given, add :—Panama, Bugaba, Volcan de Chiriqui (Champion). 
A single female specimen from Chontales served me for the description of this 
species ; the numerous examples since received, obtained principally at Bugaba, do not 
differ from it to any marked degree, and amongst them are many males; these latter 
have the tarsi entirely black, and the first joint of the anterior pair (as usual) broadly
