ACYLOPHORUS (p. 324). 
4 (a). Acylophorus versicolor. 
Niger, nitidus, abdomine versicolore ante apicem obscure rufo-cingulato, antennarum basi pedibusque rufo 
obscuris ; scutello crebre punctato. 
Long. 9 millim. 
Hab. Mexico, Tehuantepec (Hége). 
Similar to A. simplex, but readily distinguished by the closely punctate scutellum 
and the colour of the hind body, and differing also in numerous other particulars. The 
antenne are rather long, and the base of the elongate basal joint is brown. The head 
is dull beneath, pubescent, and sparsely punctate, the parts of the mouth red, with the 
apical joint of the maxillary palpi darker. The elytra are longer than the thorax, 
closely and rather closely punctate. The hind body has fulgid reflections, is densely 
punctured and very strongly pubescent, the spinose sete of the hind margins of the 
segments largely developed; the hinder part of the penultimate segment and the base 
of the following segment are red, the white membranous border of the penultimate 
segment very distinct. One example. 
QUEDIONUCHUS (p. 336). 
Quedionuchus impunctus (p. 336). 
Add:—Var. 3. Abdomine rufo-testaceo. 
Hab. Mexico, Ciudad in Durango (Hége). 
A small series of this variety was obtained: both it and the form with red elytra 
may, perhaps, prove to be distinct. 
CYRTOTHORAX (p. 340). 
Cyrtothorax salvini (p. 341). (Tab. VIII. fig. 11.) 
The reference to the figure was accidentally omitted on p. 541. 
Group PLATYPROSOPINA. 
(To precede Xanthopygina, p. 342.) 
PLATYPROSOPUS. 
Platyprosopus, Mannerheim, Brach. p. 36 (1830) ; Erichson, Gen. et Spec. Staph. p. 292. 
This genus is widely distributed in the tropical regions of the Old World, but in the 
New World has hitherto been only detected in the Amazons Valley, where the species 
are rather numerous. 
1. Platyprosopus mexicanus. 
Angustus, parallelus, fusco-rufus, capite prothoraceque piceis, antennis pedibusque testaceis ; prothorace nitido, 
seriebus punctorum discoidalibus brevibus parum discretis, ad latera parce punctatis; elytris abdomineque 
opacis, dense subtiliter punctatis. 
Long. 9 millim. 
Hab. Mexico, San Juan Bautista in Tabasco (Hoge), Tlacotalpam (Lohr).
