Homalota ex parte, Er. 
This genus has been comparatively recently established by the above writers for three 
or four European species placed by previous authors in the great genus Homalota. 
Little is known about the genus beyond the limits of Europe; but Fauvel has recently 
described a species from Australia as pertaining to the genus. The New-world species 
here described are extremely similar in appearance to the European members of the 
genus; but two of them have the intermediate coxe more distant. The other species, 
. mexicana, makes a close approach to Zachyusa. 
1. Gnypeta nigricans. 
Nigra, nitida, pube tenuissima dense vestita, subtilissime punctata, pedibus fusco-testaceis ; prothorace sub- 
quadrato, postice leviter angustato, basi bifoveolata. 
Long. 3 lin. 
Hab. Mexico, Guanajuato (Dugeés, coll. Sallé); Guaremaua, Guatemala city and San 
Geronimo (Champion). 
Antenne only moderately long and slender, third joint a little shorter than second, 
tenth slightly transverse. Head as broad as the thorax, with a fine punctuation of 
impressed punctures, and with a depression on the middle. Thorax a good deal 
narrower than the elytra, slightly but distinctly narrowed behind, its punctuation 
scarcely visible, at the base in front of the scutellum with two small foves very close 
together. LElytra very indistinctly punctulate, a little longer than the thorax. Hind 
body rather broad, sparingly and very indistinctly punctulate. Legs infuscate yellow, 
with the tarsi yellow. 
The species is extremely similar to the European G. labilis; but the extremely fine 
punctuation is less dense, and the prothorax is distinctly narrowed behind, and on the 
under surface the intercoxal process of the mesosternum is considerably broader and 
has a truncate apex. 
2. Gnypeta fragilis. 
Nigra, nitida, abdominis basi sordide testacea; pube subtilissima vestita, subtilissime punctata, pedibus 
testaceis, tibiis antennisque fusco-testaceis, his articulo ultimo elongato, colore dilutiore; prothorace ” 
transversim subquadrato, postice leviter angustato ; abdomine dense subtilissime punctato. 
Long. 2? millim. 
Hab. Guatemata, Paso Antonio 400 feet (Champion). 
Antenne slender, rather elongate, fuscous in colour, the terminal joint paler than 
those preceding it, and rather longer than the ninth and tenth together, the latter 
not transverse. Head rather short and broad, scarcely visibly punctulate. Thorax
