Umbonia gladius, Fairm. Ann. Soc. Ent. Fr. sér. 2, iv. p. 275, t. 6. figg. 4, 5°. 
Hab. Mexico, Valladolid and Temax in Yucatan (Gaumer), Campeachy!. 
About twenty-five examples, all, with one exception, females. This species appears 
to belong to Umbonia, although it differs from the other members of the genus by its 
broad, compressed, perpendicular horn. U. gladius appears to be either rare or very 
local, for I have not seen it in any other collection. I have not had the opportunity 
of examining the type-specimen which Fairmaire records as in Guérin’s collection, but 
his description and figure easily admit of identification. The single male specimen 
above referred to is much smaller than the females, with the dorsal horn shorter, and 
the pronotum only slightly reaching beyond the abdomen, and the tegmina projecting 
considerably beyond its apex. 
A specimen from Valladolid is figured. 
| HOPLOPHORA. 
Hoplophora, Germar, Rev. Ent. Silb. iii. p. 240 (1835) ; Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. 
p- 269; Stal, Kong]. Sv. Vet.-Ak. Handl. Band vii. 1, p. 37; ibid. Ofv. Vet.-Ak. Férh.

This genus, as restricted by Stal, contains about a dozen species from Central or 
Tropical South America, and one is recorded by Fairmaire from North America; they 
are stout and broad insects, varying considerably in size, with the pronotum short and 
shield-shaped, sinuate behind the horns, which are short and blunt, then nearly parallel 
for a certain distance, and then gradually narrowed to a sharp point, which scarcely 
reaches the apex of the body; the tegmina are much longer than the pronotum, and 
are furnished with long, more or less oblong areas, bounded by distinct thick veins ; 
there is no trace of a dorsal horn. The genus may be easily distinguished from Platy- 
cotis (apart from the dorsal horn or process, which in the latter genus is occasionally 
almost wanting) by the much narrower head and by the shape of the pronotum behind 
the horns.

Hoplophora monogramma, Germ. Rev. Ent. Silb. iii. p. 242°. 
Hoplophora sanguinosa, Fairm. Ann. Soc. Ent. Fr. sér. 2, iv. p. 2707. 
Hab. Mexico 1”, Omilteme and Xautipa in Guerrero (H. H. Smith), Jalisco (Schu- 
mann), Orizaba (Bilimek, in Mus. Vind. Ces.), Oaxaca; GuATEMALA, Cerro Zunil 
4000 to 5000 feet (Champion). 
This species is very variable in size and colour ; it may, however, be distinguished by 
the fact that the central keel of the pronotum from the centre of the dorsum to just
